Description

Generic Omnicef is a semi-synthetic (partially man-made) oral antibiotic in the cephalosporin family of antibiotics. Like other cephalosporins cefdinir stops bacteria from multiplying by preventing bacteria from forming walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Bacteria cannot survive without a cell wall. Generic Omnicef is active against a very wide spectrum of bacteria, including Staphylococcus aureus; Streptococcus pneumoniae; Streptococcus pyogenes (the cause of strep throat); Hemophilus influenzae; Moraxella catarrhalis; E. coli ; Klebsiella; and Proteus mirabilis. It is not active against Pseudomonas. Therapeutic uses of cefdinir include otitis media (infections of the middle ear), infections of soft tissues, and respiratory tract infections.

Generic name of Generic Omnicef is Cefdinir.

Omnicef is also known as Cefdinir, Sefdin, Adcef.

Brand name of Generic Omnicef is Omnicef.

Dosage

Generic Omnicef is taken once or twice daily, depending on the nature and severity of the infection.

The capsules or suspension can be taken with or without food.

Patients with advanced renal disease may need to take lower doses to prevent accumulation of cefdinir since it is eliminated from the body by the kidneys.

For adult infections the usual dose is 300 mg every 12 hours or 600 mg per day for 5-10 days depending on the nature and severity of the infection.

The recommended dose for children 6 months to 12 years of age is 7 mg/kg every 12 hours or 14 mg/kg per day for 5-10 days depending on the infection.

For most infections once daily dosing is as effective as twice daily dosing, though once daily dosing has not been evaluated for the treatment of skin infections or pneumonia.

Do not stop taking Generic Omnicef suddenly.

Overdose

If you overdose Generic Omnicef and you don't feel good you should visit your doctor or health care provider immediately.

Storage

Store at room temperature between 20 and 25 degrees C (68 and 77 degrees F) away from moisture and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

Previous studies suggest that the unexplained sudden and severe onset of obsessive-compulsive disorder (OCD) and/or tics may be infection or immune precipitated. Beta lactam antibiotics may be neuroprotective beyond their antimicrobial efficacy. We examine the preliminary safety and efficacy of cefdinir in reducing obsessive-compulsive and/or tic severity in children with new-onset symptoms.

A total of 2767 children with severe acute malnutrition were enrolled. In the amoxicillin, cefdinir, and placebo groups, 88.7%, 90.9%, and 85.1% of the children recovered, respectively (relative risk of treatment failure with placebo vs. amoxicillin, 1.32; 95% confidence interval [CI], 1.04 to 1.68; relative risk with placebo vs. cefdinir, 1.64; 95% CI, 1.27 to 2.11). The mortality rates for the three groups were 4.8%, 4.1%, and 7.4%, respectively (relative risk of death with placebo vs. amoxicillin, 1.55; 95% CI, 1.07 to 2.24; relative risk with placebo vs. cefdinir, 1.80; 95% CI, 1.22 to 2.64). Among children who recovered, the rate of weight gain was increased among those who received antibiotics. No interaction between type of severe acute malnutrition and intervention group was observed for either the rate of nutritional recovery or the mortality rate.

Of 447 children enrolled, 230 were clinically and bacteriologically evaluable (74% 2 years old or younger; 57% treated for AOM in previous 3 months). Bacteriologic eradication, based on repeat tympanocentesis on days 4-6, was achieved in 74% (170 of 230) of children; 76% (201 of 266) of AOM pathogens were eradicated. Eradication of penicillin-susceptible, -intermediate and -resistant S. pneumoniae was 91% (50 of 55), 67% (18 of 27) and 43% (10 of 23), respectively (P < 0.001); eradication of H. influenzae was 72% (90 of 125). Overall clinical response at days 12-14 was 83% (76 and 82% for children with S. pneumoniae and Haemophilus influenzae, respectively). Sustained clinical response at days 25-28 was 85%. Clinical response was 83% for culture-positive children versus 96% for culture-negative children at baseline tympanocentesis (P < 0.001).

We examined the attachment of Staphylococcus aureus to plastic tissue-culture coverslips after incubation for 24 h. The attachment to coverslips was weaker in rabbit plasma with 5% zinc oxide (ZnO) than in the control rabbit plasma without ZnO (P < 0.01). Plasma coagulation by S. aureus strains was not detected in plasma with 5% ZnO after incubation for 24 h. The membranous structure (an immature biofilm) was formed on the coverslips by S. aureus cells in plasma after incubation for 24 h. The colony counts of S. aureus cells on the membranous structures were lower in plasma with 5% ZnO, plasma with 0.2% hinokitiol, plasma with 5% ZnO + 0.2% hinokitiol, plasma with cefdinir at 4 minimum inhibitory concentration (MIC) and plasma with levofloxacin at 4 MIC, than in the control plasma after incubation for 24 h (P < 0.01). The colonies on the membranous structures completely disappeared in the case of plasma with 5% ZnO and 0.2% hinokitiol. The colony counts on membranous structures were lower in plasma with cefdinir at 4 MIC or levofloxacin at 4 MIC containing 5% ZnO than in plasma with cefdinir at 4 MIC or levofloxacin at 4 MIC only, (P < 0.05). The MICs of hinokitiol against S. aureus strains peaked at an MIC distribution of 16-32 micrograms/ml. The peak shifted to below 1 microgram/ml by adding 5% ZnO in agar plate method. The results suggest that the attachment of S. aureus cells to the coverslips is suppressed in the presence of 5% ZnO and that antistaphylococcal activities of cefdinir, levofloxacin and hinokitiol increase in the presence of 5% ZnO.

We studied the clinical efficacy of cefdinir (CFDN), a new oral cephalosporin, in 18 children with ages 2 years and 4 months to 11 years and 4 months with pediatric infections. The diagnoses consisted of respiratory tract infections in 15 cases, impetigo in 2 and balanoposthitis in 1. Clinical efficacies were excellent in 11 patients and good in 7, with an efficacy rate of 100%. Bacteriologically, 9 (64.3%) of the 14 strains of clinical isolates were eradicated. No side effects nor abnormal laboratory findings were observed. We have concluded that CFDN is a useful antibiotic for the treatment of mild to moderate pediatric infections.

Antimicrobial susceptibilities for fosfomycin (FOM), cephalexin, cefpodoxime, cefdinir, cefditren, ampicillin, sulbactam/ampicillin, imipenem (IPM), panipenem, meropenem (MEPM), biapenem, levofloxacin (LVFX), gatifloxacin, pazufloxacin, prulifloxacin and sulfamethoxazole/trimethoprim were determined by an agar dilution method using Mueller-Hinton agar (MHA) in Escherichia coli, Klebsiella spp., Serratia marcescens, Citrobacter spp., Enterobacter spp. and Proteus mirabilis, which were isolated from patients in 2003-2004. Those for FOM were determined by the agar dilution methods using MHA containing glucose-6-phosphate (G6P) under aerobic conditions, MHA under anaerobic conditions and nutrient agar under aerobic conditions. Those for FOM, LVFX, IPM and MEPM were also determined by an Etest method. The results by the agar dilution method showed that carbapenems had good antibacterial activities in all isolates, whereas MIC ranges for other antimicrobials were broad. Our results showed that the agar dilution method for FOM using MHA containing G6P under aerobic conditions provided reliable MICs in E. coli, which agreed with data previously reported. The results by the agar dilution method for LVFX, IPM and MEPM showed the high rate of agreement compared with those by the Etest method. In E. coli, the results for FOM by the agar dilution method using MHA containing G6P showed the high rate of agreement compared with the Etest results, although the rate was affected by bacterial species and culture conditions in various ways.

ss-Lactamase-producing (BLP) strains with the bla gene were identified in 16 (2.5%) of isolates. PGM strains were identified in 279 (43.3%) isolates. There were 242 (37.6%) PGM1-nonBLP strains with mutations in variable mutated locus of ftsI, 35 (5.4%) PGM2-nonBLP strains with mutations in highly mutated locus of ftsI, 2 (0.3%) BLP-PGM strains with mutations in ftsI and producing ss-lactamase. BLP-nonPGM strains producing ss-lactamase without mutations in ftsI were identified in 14 (2.2%) isolates. MICs of PGM1-nonBLP strains to AMP were 0.5-2.0 microg/ml. The MIC(90) of CDN to the PGM1-nonBLP strains was lowest (0.06 microg/ml). Proportions of PGM1-nonBLP strains rapidly increased during 1999 to 2002 and then decreased in 2003. In contrast, PGM2-nonBLP strains increased in 2003.

FK482 is an oral aminothiazolyl hydroxyimino cephalosporin with a C-3 vinyl group. Its activity was compared with those of cephalexin, cefuroxime, cefixime, and amoxicillin-clavulanate. FK482 inhibited 90% of Staphylococcus aureus isolates at 1 micrograms/ml and 90% of Streptococcus pyogenes, Streptococcus agalactiae, and Streptococcus pneumoniae isolates at less than or equal to 0.012 micrograms/ml, superior to cephalexin and cefuroxime and similar to cefixime. It did not inhibit oxacillin-resistant S. aureus. FK482 inhibited 90% of Enterococcus faecalis isolates at 8 micrograms/ml. Although 90% of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella species, and Shigella species isolates were inhibited by less than or equal to 2 micrograms/ml, FK482 was less active than cefixime against Citrobacter, Enterobacter, Morganella, Serratia, and Providencia species, with MICs for many isolates of greater than 8 micrograms/ml. FK482 inhibited Haemophilus influenzae and Neisseria gonorrhoeae at concentrations comparable to that of cefixime and superior to those of cephalexin and cfaclor. Bacteroides and Pseudomonas species were resistant. FK482 was not hydrolyzed by the TEM-1 and TEM-2 beta-lactamases but was hydrolyzed by TEM-3 and the Proteus vulgaris enzyme. It had a high affinity for chromosomal beta-lactamases.

The therapeutic activities of orally administered FK482 were compared with those of reference antibiotics against systemic and local infections with a variety of bacteria in mice and rabbits. In systemic infections in mice, oral FK482 was almost as effective as oral cefaclor (CCL) and more effective than oral cephalexin (CEX) against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis infections. However, FK482 afforded superior protective activity when given subcutaneously against E. coli infection in mice, and this activity was more potent than that of subcutaneously given CCL. In comparison with CCL, the reason that the in vivo activity of orally given FK482 against mouse systemic infections was weaker than had been anticipated from its potent in vitro activity was due to its poor oral absorption in mice. In local infections in rabbits, a species in which FK482 was better absorbed than in mice, FK482 was more effective than CCL, CEX or amoxicillin (AMPC). Against pneumonia induced by S. aureus or Streptococcus pyogenes, FK482 was as effective as AMPC and more effective than CCL in reducing the number of viable bacteria in the lungs of infected rabbits. In the oral treatment of experimental ascending pyelonephritis in rabbits, FK482 was superior to CCL and AMPC against methicillin-resistant S. aureus infection, as effective as AMPC and more effective than CCL against Enterococcus faecalis infection, and as effective as cefixime (CFIX) and more effective than CCL and AMPC against E. coli infection in reducing the number of viable bacteria in the kidneys and urine.

We consider studies in which an enrolled subject tests positive on a fallible test. After an intervention, disease status is re-diagnosed with the same fallible instrument. Potential misclassification in the diagnostic test causes regression to the mean that biases inferences about the true intervention effect. The existing likelihood approach suffers in situations where either sensitivity or specificity is near 1. In such cases, common in many diagnostic tests, confidence interval coverage can often be below nominal for the likelihood approach. Another potential drawback of the maximum likelihood estimator (MLE) method is that it requires validation data to eliminate identification problems. We propose a Bayesian approach that offers improved performance in general, but substantially better performance than the MLE method in the realistic case of a highly accurate diagnostic test. We obtain this superior performance using no more information than that employed in the likelihood method. Our approach is also more flexible, doing without validation data if necessary, but accommodating multiple sources of information, if available, thereby systematically eliminating identification problems. We show via a simulation study that our Bayesian approach outperforms the MLE method, especially when the diagnostic test has high sensitivity, specificity, or both. We also consider a real data example for which the diagnostic test specificity is close to 1 (false positive probability close to 0).

Among orally administered cephalosporins, aminopenicillins (+/- clavulanate), and macrolides, cefditoren was the most potent agent against Haemophilus influenzae (MIC(50/90), < or =0.008/0.03 microg/mL; 316 isolates including 100 beta-lactamase-positive and 10 beta-lactamase-negative ampicillin-resistant [BLNAR]) and was 32-, 64-, and 512-fold more potent than cefdinir, cefuroxime, and cefprozil, respectively. Cefditoren (MIC(50), 0.03 microg/mL) was also > or =32-fold more active against BLNAR phenotypes, although newer macrolides provided complete coverage against these strains. All Moraxella catarrhalis isolates were inhibited by cefditoren (0.5 microg/mL), including beta-lactamase producers (MIC(50), 0.12 vs < or =0.008 microg/mL). Cefditoren retains potent activity against respiratory tract isolates in the United States, including those with resistance phenotypes.

The in vivo antibacterial activities of a new oral trinem, sanfetrinem cilexetil (a prodrug of sanfetrinem), were evaluated in comparison with those of cefdinir and amoxicillin. Sanfetrinem cilexetil showed potent efficacy against experimental murine septicemia caused by Staphylococcus aureus, Streptococcus pyogenes, and Escherichia coli and against murine respiratory infections caused by Streptococcus pneumoniae. Likewise, in murine models of respiratory infection by penicillin-susceptible and penicillin-resistant S. pneumoniae, sanfetrinem cilexetil was more effective than amoxicillin in reducing the number of bacteria in infected lungs. These results were reflected in its potent in vitro activity and high levels in plasma.

Various 7 beta-[2-(2 buy omnicef -aminothiazol-4-yl)-2-substituted acetamido]-3-vinyl-3-cephem-4-carboxylic acid derivatives (Ia--e, IIa--g) were synthesized in order to find a new orally active cephalosporin improving the antibacterial activity of cefixime (CFIX) against Staphylococcus aureus. These derivatives include three types of alpha-substituted 2-(2-aminothiazol-4-yl)acetyl side chain; i) mono or non substituted acetyl moiety, ii) carboxyalkoxyimino acetyl moiety, iii) phosphonomethoxyimino and hydroxyimino acetyl moiety. Their structure-activity relationships and urinary recoveries in rats were studied. As a result, the compound with a hydroxyimino acetyl side chain (IIg, FK482) showed good oral absorption and excellent antibacterial activity against both gram-positive and gram-negative bacteria and was selected as a candidate for clinical trial.

Acute otitis media (AOM) is not only the most common bacterial infection in children in the United States, it is also the most common indication for the prescription of antibiotics. Unfortunately buy omnicef , antibiotic resistance to pathogens (Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis) typically causative of AOM, continues to increase. More than 30% of the beta-lactamase producing H. influenzae are resistant to amoxicillin and virtually all strains of M. catarrhalis are beta-lactamase-positive. The emergence of multidrug-resistant strains, particularly S. pneumoniae, complicates the management of AOM and increases the risk for treatment failure. Because of growing resistance, the Centers for Disease Control and the American Academy of Pediatrics promote the judicious use of antibiotics in the treatment of AOM. Their recommendations emphasize the importance of distinguishing AOM from otitis media with effusion, minimizing the use of antibiotics, and discerning between first- and second-line antibiotics in the treatment of simple uncomplicated AOM versus non-responsive/recurrent AOM. Because spontaneous cure rates are lower in complicated AOM and AOM secondary to S. pneumoniae infection, antibiotic therapy remains an appropriate treatment option for most children with AOM. When amoxicillin, the treatment of choice in AOM, is not effective or not tolerated in children, the prescriber should consider an alternative that displays not only excellent antimicrobial activity against the suspected pathogens, but also characteristics, such as convenient dosing, tolerability, and palatability, that promote compliance and adherence in children. The cephalosporins offer an alternative to penicillins. Cephalosporins such as cefuroxime axetil (second-generation) and cefdinir and cefpodoxime proxetil (third-generation), offer a broad spectrum of activity and are approved for use in a convenient once- or twice-daily dosing schedule, thus increasing the likelihood of compliance with the full course of therapy. Cefdinir is a possible second-line alternative to amoxicillin for children with AOM, particularly among children who are likely to be noncompliant with a two- to three-times-daily dosing schedule, and those instances where there is a high likelihood for, or a known infection with an amoxicillin-resistant pathogen.

We examined the substrate specificity of human organic anion transporter (hOAT) 1 and hOAT3 for various cephalosporin antibiotics, cephaloridine, cefdinir, cefotiam, ceftibuten, cefaclor, ceftizoxime, cefoselis and cefazolin by using HEK293 cells buy omnicef stably transfected with hOAT1 or hOAT3 cDNA (HEK-hOAT1, HEK-hOAT3). Additionally, we examined the uptake of various compounds by these transfectants. The mRNA level of hOAT3 in HEK-hOAT3 was about three-fold that of hOAT1 in HEK-hOAT1. Functional expression of hOAT1 and hOAT3 was confirmed by the uptake of p-[14C]aminohippurate and [3H]estrone sulfate, respectively. p-[14C]Aminohippurate, [3H]estrone sulfate, [14C]captopril, [3H]methotrexate, [3H]ochratoxin A, [3H]leucovorin and [3H]cimetidine were shown to be substrates for hOAT1 and hOAT3, and [3H]dehydroepiandrosterone sulfate was shown to be a substrate for hOAT3. All cephalosporin anitibiotics tested were shown to inhibit the uptake of p-[14C]aminohippurate and [3H]estrone sulfate via hOAT1 and hOAT3, respectively, in a dose-dependent manner, and the IC50 values of these antibiotics, except for cefaclor, for the hOAT1-mediated uptake of p-[14C]aminohippurate were within four-fold of those for the hOAT3-mediated uptake of [3H]estrone sulfate. The uptake of cephaloridine, cefdinir and cefotiam by HEK-hOAT3 was 35-50-fold greater than that by control cells. Moreover, the accumulation of the other cephalolsporin antibiotics was significantly greater in HEK-hOAT3 than in control cells. In contrast, the uptake of these antibiotics by HEK-hOAT1 was within two-fold of that by control cells. In conclusion, hOAT3 plays a more important role than hOAT1 in the renal secretion of cephalosporin antibiotics.

Intestinal absorption of the orally active cephalosporin, cefdinir, was investigated using brush-border membrane vesicles prepared from rabbit small intestine. The initial uptake of cefdinir was pH-dependent, with increased uptake at acidic pH, and was not influenced by either sodium gradient or membrane potential difference buy omnicef . Cefdinir uptake was saturable with an apparent Michaelis constant of 8.1 mM. Initial uptake of cefdinir was inhibited by dipeptides (glycyl-L-proline and glycylsarcosine), beta-lactam antibiotics (cephradine, cefixime and penicillin V), and monocarboxylic acids (acetic acid and L-lactic acid), whereas the uptake of cephradine and cefixime was not inhibited by monocarboxylic acids. Cefdinir significantly inhibited the initial uptake of cephradine, cefixime and [3H]acetic acid. From these results, it was suggested that cefdinir was transported across brush-border membranes by both dipeptide and monocarboxylic acid carriers.

Complications of laser resurfacing include infections, scarring, hyperpigmentation, hypopigmentation, and delayed healing. Postoperative infections cause pain, prolonged healing, and can result in scarring. Ablative laser techniques cause partial- or full-thickness wounds, whereas so-called "nonablative procedures" may cause "spotty" epidermal wounds. Antibiotic prophylaxis is necessary when the risk for postoperative infection is significant or when the risk of infection is moderate but the consequences of infection are significant. Prophylactic antibiotic agents should have a broad spectrum buy omnicef of activity, be well-tolerated and be safe. The most appropriate choice is a broad-spectrum agent such as cefdinir, even for patients allergic to penicillin. Additionally, all patients should be treated prospectively with antivirals to prevent activation and dissemination of herpes simplex virus type I. Treatment of infections in patients who have and have not received prophylactic antibiotics requires identification of the causative factor and appropriate treatment. Nonablative treatments such as photodynamic therapy do not usually require antibiotic prophylaxis, although a few patients treated for acne may acquire a secondary bacterial infection that should be treated.

The bactericidal activity and the postantibiotic effect (PAE) of cefdinir (Cl 983, FK 482) (CDR), were determined against Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Branhamella catarrhalis and Escherichia coli (5 strains each) in comparison to erythromycin (E), cotrimoxazole (SXT) and amoxicillin-clavulanic acid (AMC). Kinetic studies of kill showed that CDR was rapidly bactericidal at concentrations 2 and 4 times the minimum inhibitory concentration (MIC): a reduction of 99.9% in CFU values was observed after 6-8 h for many of the isolates tested. As expected, a PAE was observed when S. aureus was treated with CDR at MIC (range of individual values for 5 strains 0.8-1.5 h) and 4 x MIC (range 1.1-1.4 h). Moreover, CDR showed a significant PAE at both its MIC and 4 x MIC against S. pneumoniae (range 0.5-1.0 h and 0. buy omnicef 9-1.1 h), H. influenzae (range 0.4-0.7 h and 0.4-0.8 h), B. catarrhalis (range 0.5-0.7 h and 0.65-0.95 h) and E. coli (range 0.5-0.6 h and 0.5-0.7 h). The good bactericidal activity and the significant PAE of CDR against Gram-positive and Gram-negative bacteria (including respiratory pathogens) are a promising indication for the clinical efficacy of this cephalosporin in several bacterial infections.

Among Haemophilus influenzae isolated from buy omnicef children with respiratory tract infections, the evolution of ampicillin resistance was investigated during 1996 and 1997 in Japan. beta-Lactamase production was assessed and minimum inhibitory concentrations (MICs) of eight antimicrobial agents were determined using a broth microdilution method in Mueller-Hinton-lysed horse blood medium. Of 74 H. influenzae, 11 strains (14.9%) produce beta-lactamase and were thus highly resistant to ampicillin (MIC of >4.0 microgram/ ml). In addition, moderate resistance to ampicillin, defined as an MIC of >==1.0 microgram/ml, was noted in 44.4% of all beta-lactamase-negative isolates. These beta-lactamase-negative ampicillin-resistant (BLNAR) organisms were resistant to other cephalosporins such as cefpodoxime and cefdinir, while beta-lactamase-producing strains were susceptible to them. Cefditoren, cefteram, and minocycline were active against all strains studied, whereas cefaclor and clarithromycin were inactive against all H. influenzae isolates in this study. Results indicate that BLNAR strains have emerged among children with respiratory tract infections in Japan.

We consider studies in which an enrolled subject tests positive on a fallible test. After an intervention, disease status is re-diagnosed with the same fallible instrument. Potential misclassification in the diagnostic test causes regression to the mean that biases inferences about the true intervention effect. The existing likelihood approach suffers in situations where either sensitivity or specificity is near 1. In such cases, common in many diagnostic tests, confidence interval coverage can often be below nominal for the likelihood approach. Another potential drawback of the maximum likelihood estimator (MLE) method is that it requires buy omnicef validation data to eliminate identification problems. We propose a Bayesian approach that offers improved performance in general, but substantially better performance than the MLE method in the realistic case of a highly accurate diagnostic test. We obtain this superior performance using no more information than that employed in the likelihood method. Our approach is also more flexible, doing without validation data if necessary, but accommodating multiple sources of information, if available, thereby systematically eliminating identification problems. We show via a simulation study that our Bayesian approach outperforms the MLE method, especially when the diagnostic test has high sensitivity, specificity, or both. We also consider a real data example for which the diagnostic test specificity is close to 1 (false positive probability close to 0).

A sensitive and selective liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method was developed for the determination of cefdinir in human plasma. After a simple protein precipitation using trichloracetic acid, the post-treatment samples were applied to a prepacked RP18 Waters SymmetryShield column interfaced with a triple quadrupole tandem mass spectrometer. Positive electrospray ionization was employed as the ionization source. The mobile phase consisted of methanol-water-formic acid (25:75:0.075, v/v/v). The analyte and I.S. cefaclor were both detected by the use of selected reaction monitoring mode. The method was linear in the concentration range of 5-2,000 ng/ml. The lower limit of quantification was 5 ng/ml. The intra- and inter-day relative standard deviation across three validation runs over the entire concentration range was less than 4.3%. The accuracy determined at three concentrations (36, 360 and 1,800 ng/ml for cefdinir) ranged buy omnicef from 99.6 to 106.7% in terms of recovery. The chromatographic run time for each plasma sample was less than 3 min. The method herein described was successfully applied for the evaluation of pharmacokinetic profiles of cefdinir capsule in 12 healthy volunteers.

Bacteriological, pharmacokinetic and clinical studies on SY5555 dry syrup (powder which is dissolved before use), a new penem antibiotic for oral use, were performed. The following results were obtained. 1. Antibacterial activities. MICs of SY5555, clavulanic acid/amoxicillin (CVA/AMPC), cefotiam (CTM), cefpodoxime (CPDX), cefaclor (CCL) and cefdinir (CFDN) were determined against clinically isolated Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli and Enterobacter cloacae at a dose of 10(6) CFU/ml. MICs of SY5555 against S. aureus, CNS, S. pneumoniae, S. pyogenes, H. influenzae, M. catarrhalis, E. coli and E. cloacae were 0.2, 0.2, 0.2, < or = 0.025, 0.78, 0.2, 0.78 and 3.13 micrograms/ml, respectively, showing excellent antibacterial effects on these pathogens. Although the effects of SY 5555 against H. influenzae and E. coli were slightly inferior to those of CPDX and CFDN, the drug showed the most excellent antibacterial effect on other strains as compared with the control drugs. 2. Absorption and excretion In this study, plasma concentrations and urinary recovery rates were examined after administration of SY5555 at doses of 5 and 10 mg/kg (potency) after meals. With both 5 and 10 mg/kg doses, peak plasma concentrations were reached 1 hour after administration, at 0.25-2.61 micrograms/ml (mean 1.47 micrograms/ml) and 1 buy omnicef .08-2.17 micrograms/ml (mean 1.74 micrograms/ml), respectively. The plasma levels rapidly decreased to 0.06-0.19 micrograms/ml (0.12 micrograms/ml) and 0.0503-0.0637 micrograms/ml) after 6 hours. The half-lives 1.12 hours in the 5 mg/kg group and 1.0 hour in the 10 mg/kg group. The urinary recovery rates were determined in the first 8 hours after administration in the 5 mg/kg and 6 hours in the 10 mg/kg group, and the values were as low as 1.05-12.3% and 1.6-4.33%, respectively. 3. Clinical results The clinical responses were examined in a total of 73 cases including 4 acute pneumonia, 13 acute bronchitis, 11 tonsillitis, 3 pharyngitis, 12 scarlet fever, 2 pertussis, 6 urinary tract infection, 6 otitis media, 7 lymphadenitis, 2 staphylococcal scalded skin syndrome, 2 phlegmon, 4 impetigo and 1 purulent parotitis. The treatment was effective or better in 66 of 70 cases with an efficacy rate of 94.3% (3 undeterminable cases were excluded). Bacteriological effects were examined during the clinical course for detected or suspected pathogens found before administration of SY5555. The effects were determined in 50 cases including 7 cases of polymicrobacterial infections, 57 strains in total. Eight strains, however, persisted, hence the overall eradication rate was 86.0%.(ABSTRACT TRUNCATED AT 400 WORDS)

A novel isocratic reversed-phase high performance liquid-chromatography/ultraviolet detection method for simultaneous determination of cefdinir and cefixime in human plasma was developed and validated after optimization of various chromatographic conditions and other experimental parameters. Sample preparation based on a simple extraction procedure consisting of deproteination and extraction with 3 parts of buy omnicef 6% trichloroacetic acid aqueous solution followed by volume make up with the aqueous component of the mobile phase obtained best recoveries of the two analytes. Samples were separated on a Supelco Discovery HS C(18) (150 mm × 4.6 mm, 5 μm) analytical column protected by a Perkin Elmer C(18) (30 mm × 4.6 mm, 10 μm) guard cartridge. The mobile phase, methanol/acetonitrile (50/50, v/v):0.05% trifluoroacetic acid (19:81, v/v), operated at 50°C column oven temperature was pumped at a flow rate of 2.0 mL min(-1) and the column eluents were monitored at a wavelength of 285 nm. When Sample was injected into the Perkin Elmer high performance liquid-chromatography system through Rheodyne manual (or auto-sampler) injector equipped with 20 μL loop, separation was achieved within 4 min. The present method demonstrated acceptable values for selectivity, linearity within the expected concentration range (0.004-5.0 μg mL(-1); r(2)>0.999 for both analytes), recovery (>95% for cefdinir and >96% for cefixime), precision (%RSD<2.0 for cefdinir and <2.2 for cefixime), sensitivity (limit of detection: 1 ng mL(-1) and lower limit of quantification: 4 ng mL(-1) for both analytes), stability of solutions, and robustness. The method was efficiently applied to a pharmacokinetic study in healthy volunteers.

Of the 384 enrolled patients 303 were evaluable for clinical efficacy. Clinical success rates were statistically equivalent for the 3 treatment groups at the end of therapy: 85 of 102 (83.3%) for cefdinir QD; 81 of 101 (80.2%) for cefdinir BID; 86 of 100 (86%) for amoxicillin/clavulanate. Of the 197 evaluable patients from whom a susceptible pathogen was recovered, presumptive eradication buy omnicef rates at end of therapy were equivalent: 55 of 65 (84.6%), 54 of 66 (81.8%) and 55 of 66 (83.3%) for cefdinir QD-, cefdinir BID- and amoxicillin/clavulanate-treated patients, respectively. However, presumptive eradication rates for Streptococcus pneumoniae were significantly lower for cefdinir BID (55.2%) than for amoxicillin/clavulanate (89.5%; P = 0.0019) and marginally lower than for cefdinir QD (80%; P = 0.054). Diarrhea was the most common treatment-associated adverse reaction in all groups but was significantly more common in amoxicillin/clavulanate-treated patients (35%) than in patients who had been treated with cefdinir QD (10%, P<0.001) or cefdinir BID (13%, P<0.001).

Hydrolysis of cefdinir leads to pH-dependent isomerizations and beta-lactam ring-opening. Lactam ring opened gamma-lactones were produced as a mixture of four diastereoisomers based on the lactone methyl, and C-6 isomerizations in acidic to neutral solutions. Cefdinir and its 7-epimer were hydrolyzed to clarify the pathway leading to these lactones and the mechanism of C-6 epimerization with the aid of chiral separation techniques. Chiral separation using a bovine serum albumin column was employed to detect the beta-lactam ring opened products of cefdinir and its 7-epimer; the C-6 and C-7 isomerization was thereby observed; however, it was found to be pH-dependent at pH > or = 9. Optical activity detection applied to the lactones produced from cefdinir and its 7-epimer demonstrated that the corresponding peaks of these lactones were enantiomeric pairs. In addition, the smallest rate constant at pH 4 was observed for C-6 epimerization of the lactones, and it was found to proceed without deprotonation at C-6 Suprax Reviews by 1H-NMR spectroscopy. From the results of these studies, a plausible mechanism for C-6 epimerization has been proposed. Additionally, it was confirmed that two degradation pathways were involved during hydrolysis of cefdinir to the lactone.

OBJECTIVE To investigate the scale of antimicrobial prescribing without a corresponding visit, and to compare the attributes of patients who received antimicrobials with a corresponding visit with those who did not have a visit. DESIGN Retrospective cohort. METHODS We followed up 185,010 Medicare patients for Priligy Dapoxetine Review 1 year after an acute myocardial infarction. For each antimicrobial prescribed, we determined whether the patient had an inpatient, outpatient, or provider claim in the 7 days prior to the antimicrobial prescription being filled. We compared the proportions of patient characteristics for those prescriptions associated with a visit and without a visit (ie, phantom prescriptions). We also compared the rates at which different antimicrobials were prescribed without a visit. RESULTS We found that of 356,545 antimicrobial prescriptions, 14.75% had no evidence of a visit in the week prior to the prescription being filled. A higher percentage of patients without a visit were identified as white (P<.001) and female (P<.001). Patients without a visit had a higher likelihood of survival and fewer additional cardiac events (acute myocardial infarction, cardiac arrest, stroke, all P<.001). Among the antimicrobials considered, amoxicillin, penicillin, and agents containing trimethoprim and methenamine were much more likely to be prescribed without a visit. In contrast, levofloxacin, metronidazole, moxifloxacin, vancomycin, and cefdinir were much less likely to be prescribed without a visit. CONCLUSIONS Among this cohort of patients with chronic conditions, phantom prescriptions of antimicrobials are relatively common and occurred more frequently among those patients who were relatively healthy.

The aim of this study was to investigate the effects of micronization and amorphorization of cefdinir on solubility and dissolution rate. The amorphous samples were prepared by spray-drying (SD) and supercritical anti-solvent (SAS) process, respectively and their amorphous natures were confirmed by DSC, PXRD and FT-IR. Thermal gravimetric analysis was performed Micronase Drug Form by TGA. SEM was used to investigate the morphology of particles and the processed particle had a spherical shape, while the unprocessed crystalline particle had a needle-like shape. The mean particle size and specific surface area were measured by dynamic light scattering (DLS) and BET, respectively. The DLS result showed that the SAS-processed particle was the smallest, followed by SD and the unprocessed cefdinir. The BET result was the same as DLS result in that the SAS-processed particle had the largest surface area. Therefore, the processed cefdinir, especially the SAS-processed particle, appeared to have enhanced apparent solubility, improved intrinsic dissolution rate and better drug release when compared with SD-processed and unprocessed crystalline cefdinir due not only to its amorphous nature, but also its reduced particle size. Conclusions were that the solubility and dissolution rate of crystalline cefdinir could be improved by physically modifying the particles using SD and SAS-process. Furthermore, SAS-process was a powerful methodology for improving the solubility and dissolution rate of cefdinir.

A novel qualitative analytical method by using two-dimensional chromatographic correlation spectroscopy techniques for recognizing impurity peaks of HPLC methods of quality control and LC-MS chromatographic system was established. The structures of major degradation products of ceftizoxime and cefdinir were identified by LC-MS and MassWorks application; the standard chromatographic and spectral data of the degradation impurities were obtained by high-performance liquid chromatography with diode array detection. The impurity peaks of two-dimensional chromatography were matched by Mesalamine Generic Asacol comparison of spectra and calculating correlation coefficients. Peaks in chromatography can be identified accurately and rapidly in different chromatographic systems such as column and mobile phase changed. The method provides a new way and thought to identify the peaks in quality control of impurities without reference impurity substances.

Evidence in the literature suggests that 1α,25-dihydroxyvitamin D3 [1,25(OH)2 D3 ], the vitamin D receptor ligand, down-regulated the expression of the rat renal organic anion (renal organic anion transporter, rOAT) and oligopeptide (rPEPT) transporters, but increased intestinal rPEPT1 expression. We investigated, in rats, the intravenous and oral pharmacokinetics of 2 mg/kg cefdinir and cefadroxil, two cephalosporins that are eliminated via renal OAT1/OAT3 and are substrates of PEPT1/PEPT2, with and without 1,25(OH)2 D3 treatment. The area under the plasma concentration-time curve (AUC) of cefdinir or cefadroxil after 1,25(OH)2 D3 treatment was increased significantly because of decreased clearance (CL). Both kidney uptake and cumulative urinary recovery were significantly decreased, whereas liver uptake and fecal recovery remained unchanged in 1,25(OH)2 D3 -treated rats. Similar changes in AUC and CL were observed for both drugs upon coadministration of probenecid, the OAT inhibitor. Oral availability of cefdinir and cefadroxil remained unchanged with 1,25(OH)2 D3 treatment, suggesting lack of a role for intestinal rPEPT1. Rather, reduction of rOAT1/rOAT3 mRNA expression in kidney with 1,25(OH)2 D3 -treatment was observed, confirmed by decreased function in MDCKII cells overexpressing human OAT1 and OAT3. These composite results suggest that 1,25(OH)2 D3 treatment reduces cefdinir and cefadroxil clearances by diminution of renal OAT1/OAT3 expression, implicating a role for 1,25(OH)2 D3 in eliciting transporter-based drug interactions.

We conducted a retrospective cohort study of children aged 6 months to 6 years and received their first diagnosis of UTI in a network of 27 outpatient pediatric practices between July 1, 2001, and May 31, 2006. We examined the relationship between antimicrobial resistance in UTI isolates and exposure to specific antimicrobial agents (amoxicillin, amoxicillin-clavulanate, cefdinir, trimethoprim-sulfamethoxazole, and azithromycin) in the previous 120 days. We developed multivariable logistic regression models for resistance to ampicillin, amoxicillin-clavulanate, trimethoprim-sulfamethoxazole, and first-generation and third-generation cephalosporins, adjusting for potential confounders such as age, number of siblings, recent hospitalizations, and child care exposure.

The in vitro antibacterial activities of LB 10827, a new oral cephalosporin, against common respiratory tract pathogens were compared with those of six beta-lactams (cefdinir, cefuroxime, cefprozil, penicillin G, amoxicillin-clavulanate, and ampicillin), two quinolones (trovafloxacin and ciprofloxacin), and one macrolide (clarithromycin). The MIC of LB 10827 at which 90% of the penicillin-resistant strains of Streptococcus pneumoniae tested were inhibited was 0.5 microg/ml, and the drug was 4- to 32-fold more active than the compared beta-lactams. The potent activity of LB 10827 against Haemophilus influenzae and Moraxella catarrhalis was retained, and the presence of beta-lactamase in both strains had little effect on the in vitro activity of the compound. Time-kill studies revealed that LB 10827 had bactericidal activity against these respiratory pathogens. This agent reduced original counts of all pathogens tested by >/=3 log(10) CFU/ml at the MIC, and the regrowth was completely prevented for 12 h. The potent in vitro antibacterial activity of LB 10827 against respiratory pathogens has been proved in both mouse pneumonia and neutropenic rat models. These results strongly suggest that this agent has potential for the treatment of respiratory tract infections.
