Also known as:  Tizanidine.

Description

Generic Zanaflex is an agonist at (alpha) 2-adrenergic receptor sites and presumably reduces spasticity by increasing presynaptic inhibition of motor neurons. In animal models, Generic Zanaflex has no direct effect on skeletal muscle fibers or the neuromuscular junction, and no major effect on monosynaptic spinal reflexes. The effects of Generic Zanaflex are greatest on polysynaptic pathways. The overall effect of these actions is thought to reduce facilitation of spinal motor neurons.

The imidazoline chemical structure of Generic Zanaflex is related to that of the anti-hypertensive drug clonidine and other (alpha) 2 -adrenergic agonists. Pharmacological studies in animals show similarities between the two compounds, but Generic Zanaflex was found to have one-tenth to one-fiftieth (1/50) of the potency of clonidine in lowering blood pressure.

Zanaflex is also known as Tizanidine, Sirdalud.

Generic name of Generic Zanaflex is Tizanidine-Oral.

Brand name of Generic Zanaflex is Zanaflex.

Dosage

You should take it by mouth.

It usually is taken two or three times a day.

zanaflex 8 mg

We assigned randomly in a double blind study 10 children treated with tizanidine (0.05 mg/kg/day) and 30 with placebo for a 6-month period, after which they were unified in the group of tizanidine. The dependent variables were spasticity, Ashworth scale, posture tone scale, reflex scale and liver function test.

The long latency M2 electromyographic response of a suddenly stretched active muscle is stretch duration dependent of which the nature is unclear. We investigated the influence of the group II afferent blocker tizanidine on M2 response characteristics of the m. flexor carpi radialis (FCR). M2 response magnitude and eliciting probability in a group of subjects receiving 4 mg of tizanidine orally were found to be significantly depressed by tizanidine while tizanidine did not affect the significant linear relation of the M2 response to stretch duration. The effect of tizanidine on the M2 response of FCR is supportive of a group II afferent contribution to a compound response of which the stretch duration dependency originates from a different mechanism, e.g., rebound Ia firing.

A double-blind clinical trial has been performed on 70 candidates for elective abdominal surgery undergoing general anesthesia in Educational Hospital of Ghaem, Mashhad, Iran. 35 randomly selected patients (the case group) were given 4 mg of oral Tizanidine 90 minutes before the induction of anesthesia whereas the remaining subjects (the control group) were given placebo. Blood pressure and heart rate before and after induction of anesthesia, and after intubation and extubation, existence of postoperative shivering, and the needed Propofol dosage were measured and recorded. Data analysis was done with T-test and Chi-squared test, using SPSS software version 16.

Metanalisys results suggest that carbamazepine is more efficient than placebo. In three controlled studies comparing lamotrigine, topiramate and 0.5% proparacaine hydrochloride, only lamotrigine was superior to placebo. Dextromethorphan was compared to low-dose lorazepam, with increased pain with dextromethorphan. Three studies have compared carbamazepine to tizanidine, tocainide and pimozide, and only pimozide was superior to carbamazepine.

Variations of blood pressure and heart rate after anesthesia induction, intubation and extubation were less in Tizanidine group generally. Postoperative shivering was reported in 28.6% and 11.4% of patients in control and case group respectively. Average propofol needed dose for anesthesia maintenance in case group was 25% less than the needed amount in the control group.

Tizanidine, a centrally acting skeletal muscle relaxant, is metabolized mainly by cytochrome P450 (CYP) 1A2 and has a low oral bioavailability. The fluoroquinolone antibiotic ciprofloxacin is only a moderately potent inhibitor of CYP1A2. Our objective was to study the extent and mechanism of a possible interaction of ciprofloxacin with tizanidine.

Fifty healthy patients participated in this prospective clinical study. The test group received tizanidine (4 mg in the evenings for the first 2 postoperative days) in addition to antibiotic and antiinflammatory medications. Postoperatively, 1 independent investigator performed clinical examinations. Appropriate statistical analysis was used to evaluate data.

The paper considers mechanisms of action and clinical efficacy of the drug sirdalud (tizanidine) in painful musculotonic syndromes. Sirdalud is an agonist of alpha 2-adrenergic receptors effective in painful musculotonic syndromes and spasticity of various genesis. The drug exhibits myorelaxative and direct central analgetic effects, is well tolerated and has minimal side effects (drowsiness). The response can be seen as early as the first treatment days. Sirdalud is applicable as alone and in combination with non-steroid anti-inflammatory drugs.

zanaflex r180 dosage

Twelve spastic patients received single oral doses of a new anti-spastic drug DS103-282 (Sandoz) 6 mg, baclofen 20 mg, and placebo on three separate days. Passive stretch responses were measured before administration and for four hours afterwards. DS103-282 was more effective than baclofen, and both drugs were more effective than placebo. Analysis of the recordings confirmed that DS103-282 had a specific effect upon stretch reflexes independent of its effect on resting muscle tone. Its action appeared at 30 to 45 minutes after ingestion, with maximum activity at 60-90 minutes. Unwanted effects of DS103-282 were drowsiness and (in one case) potentiation of antihypertensive therapy.

The spectrum of antispasticity therapies is fairly broad. Familiarity with the various therapies will enable a nurse involved in the care of neurological patients to deliver the effective treatment and minimize adverse events. Referral to specialty care centers may be appropriate for selected patients who require more complex interventions for spasticity control.

zanaflex reviews

Eight children and young adults from East Denmark with spasticity and 12 with dystonia aged 3-18 years (median 10.9 years) were tested, operated and treated with continuous intrathecal baclofen for a period of 2-64 months (median 22.2 months). Registration of efficacy, fillings, adjustments of baclofen and other therapies were performed in an out patient setting since 1995.

Methodological quality of studies (allocation concealment, blinding, patients characteristics, inclusion and exclusion criteria; interventions; outcomes; lost to follow up) was independently assessed by two investigators. The heterogeneity among studies did not allow quantitative combination of results.

zanaflex generic 6mg

Twenty-three placebo-controlled studies (using baclofen, dantrolene, tizanidine, botulinum toxin, vigabatrin, prazepam and threonine) and thirteen comparative studies met the selection criteria. Only thirteen of these studies used the Ashworth scale, of which only three of the six placebo-controlled trials and none of the seven comparative studies showed a statistically significant difference between test drugs. Spasms, other symptoms and overall impressions were only assessed using unvalidated scores and results of functional assessments were inconclusive.

The antagonistic effects of MDL73005EF and tamsulosin and partial agonists clonidine and tizanidine at rat thoracic aorta and rabbit iliac artery alpha1-adrenoceptors were investigated in this study. Selective alpha1-adrenoceptor antagonists MDL73005EF and tamsulosin dose-dependently shifted the concentration-response curves for noradrenaline to the right. Schild plots of the results obtained from the inhibition by MDL73005EF (pA2 8.30 +/- 0.04) and tamsulosin (pA2 10.51 +/- 0.06) of noradrenaline yielded a straight line with a slope of unity in rat thoracic aorta. The slopes of Schild plots obtained from the inhibition by MDL73005EF and tamsulosin of noradrenaline were significantly different from unity in rabbit iliac artery. Schild plots of the results obtained from the inhibition by clonidine and tizanidine of noradrenaline yielded a straight line with a slope of unity in rat thoracic aorta (pA2 7.08 +/- 0.04 and 7.32 +/- 0.04, respectively). These results suggest that alpha1D-adrenoceptors play a significant role in the alpha1-adrenoceptor-agonist-induced contraction of rat thoracic aorta and rabbit iliac artery, and that clonidine and tizanidine interact with the alpha1D-adrenoceptor subtype as competitive antagonists in rat thoracic aorta.

Treatment with tizanidine was carried out with 1 mg/ day in 18 mo-7 yr old children, 2 mg/day in 7-12 yr old children as initial doses, and for those older than 12 yr similar dosing to that in adults. Tolerance was excellent in 79.3 % of children. Sedation was the most uncomfortable side- effect. Subjective assessment by 92.9 % of parents was good.

In the studied real-life setting, we found a considerable number of MQAB users with additional risk factors for TdP but no ECG monitoring. However, adverse drug reactions were rarely found, and costs vs. benefits of ECG monitoring have to be weighted. In contrast, avoidable risk factors and selected contraindicated pharmacokinetic interactions are clear targets for implementation as automated alerts in electronic prescribing systems.

zanaflex tizanidine reviews

We report a case of delirium accompanied by extrapyramidal symptoms and autonomic dysfunction in a 59-year-old man following abrupt cessation of baclofen and tizanidine. An extensive search for the etiology was undertaken, but it was only after a careful history was taken that suspicion for baclofen and tizanidine withdrawal was raised. The delirium and motor disturbances resolved within 24 h of reintroduction of baclofen. Withdrawal from muscle relaxants requires a high index of suspicion but should be considered in patients who manifest signs and symptoms of withdrawal from the medications, particularly visual hallucinations, rigidity and autonomic dysfunction.

From 2000-2011, there was a significant increase (5.9% per year, CI 3.6, 8.2) in unintentional pediatric exposures to National Poison Data System for central alpha-2 agonists. There were 27,825 clonidine exposures (67.3% male, median age: 4 years), 6143 guanfacine exposures (69.8% male, median age: 6 years), and 856 tizanidine exposures (51.9% male, median age: 2 years). Guanfacine had the greatest proportional increase among the medications. Clonidine was associated with the most respiratory (799, 2.9%) and central nervous system symptoms (12,612, 45.3%), as well as the most episodes of bradycardia (2847, 10.2%) and hypotension (2365, 8.5%). Seven-hundred twenty-eight (2.0%) patients were intubated, and 141 patients (0.5%) were administered vasopressors. There were 7 cardiac arrests and 3 deaths from clonidine.

The anticonvulsant activity of 5-chloro-4-(2-imidazolin-2yl-amino)-2,1,3-benzothiazole, tizanidine, was studied following intraperitoneal (i.p.) administration in DBA/2 mice (which show sound-induced seizures). Protection against sound-induced seizures was observed after tizanidine, (0.5-4 mg/kg i.p.). The ED50 values for suppression of the tonic, clonic and wild running phases of sound-induced seizures were 0.54, 0.76 and 1.43 mg/kg, respectively. This protective action was significantly reduced by pretreatment with aminophylline (25 mg/kg i.p.), yohimbine (1 mg/kg i.p.) or piperoxan (20 mg/kg i.p.). Methysergide, a serotonin antagonists, did not significantly reduce the anticonvulsant effects of tizanidine. The present experiments suggest an involvement of purinergic and adrenergic mechanisms in the anticonvulsant action of tizanidine.

zanaflex ms reviews 2015-03-02

Based on the affinity of alpha1D adrenoceptor subtype for a selective antagonist BMY 7378, we studied its functional role in rabbit thoracic aorta and iliac artery, and evaluated the subtypes of the alpha1-adrenoceptors that are activated by phenylephrine (a full agonist) and tizanidine (a partial agonist). In thoracic aorta, the concentration response curves of phenylephrine and tizanidine were antagonized by BMY 7378 with low potency (pA2 values 6.68+/-0.06 and 6.67+/-0.06, slopes of Schild plot 1.06+/-0.04 and 1.01+/-0.04, respectively). On the other hand, in iliac artery concentration response curves for phenylephrine were potently antagonized by a low concentration of BMY 7378, and the slope ( buy zanaflex 0.75+/-0.02) of the Schild plot was significantly different from unity. In iliac artery, a concentration response curve of tizanidine was antagonized by BMY 7378 with low potency (pA2 value 6.64+/-0.08, slope of Schild plot 1.01+/-0.05). These results suggest that an alpha1D-adrenoceptor subtype contributes to alpha1-adrenoceptor mediating muscle contraction in iliac artery, but not in thoracic aorta of rabbit, and that it is activated by a full agonist phenylephrine but not by a partial agonist tizanidine.

The cytochrome P450 enzyme CYP1A2 is crucial for the metabolism of many drugs, for example, tizanidine. As the effects of several non-steroidal anti-inflammatory drugs (NSAID) and female sex steroids on CYP1A2 activity in vitro are unknown, their effects on phenacetin O-deethylation were studied and compared with the effects of model inhibitors in human liver microsomes, followed by prediction of their interaction potential with tizanidine buy zanaflex in vivo. In vitro, fluvoxamine, tolfenamic acid, mefenamic acid and rofecoxib potently inhibited CYP1A2 [the 50% inhibitory concentration (IC(50)) < 10 microM]. Ethinyloestradiol, celecoxib, desogestrel and zolmitriptan were moderate (IC(50) 20-200 microM), and etodolac, ciprofloxacin, etoricoxib and gestodene weak inhibitors of CYP1A2 (IC(50) > 200 microM). At 100 microM, the other tested NSAIDs and steroids inhibited CYP1A2 less than 35%. Pre-incubation increased the inhibitory effects of rofecoxib, progesterone and desogestrel. Using the free portal plasma inhibitor concentration and the competitive inhibition model, the effect of fluvoxamine and the lack of effects of tolfenamic acid and celecoxib on tizanidine pharmacokinetics in human beings were well predicted. However, the effects of ciprofloxacin, rofecoxib and oral contraceptives were greatly underestimated even when the predictions were based on their total portal plasma concentration. Besides rofecoxib, and possibly mefenamic acid, other NSAIDs were predicted not to significantly inhibit CYP1A2 in human beings. The type of enzyme inhibition, particularly metabolism-dependent inhibition, free inhibitor concentration and accumulation of the inhibitor into the hepatocytes should be considered in extrapolations of in vitro results to human beings.

At three months the scores of the placebo and baclofen group differed slightly for the spasm score (effect size=0.20) and substantially for the Ashworth scale (effect size=1.40) and buy zanaflex pain score (effect size=0.94); health related quality of life showed no significant differences. Three months after implantation the baclofen group showed a significant, substantial improvement on the SIP "physical health", "mental health", "mobility", and "sleep and rest" subscales and on the HSCL mental health scale; patients receiving placebo showed no change. After one year of baclofen treatment significant (P<0.05) improvement was found on the SIP dimensions "mobility" and "body care and movement" with moderate effect sizes. Improvement on the SIP subscale "physical health" (P<0.05; effect size 0.86), the SIP overall score (without "ambulation"), and the "physical health" and overall scale of the HSCL was also significant, with effect sizes >0.80. Changes in health related behaviour were noted for "sleep and rest" and "recreation and pastimes" (P<0.01, P<0.05; effect size 0.95 and 0.63, respectively).

Four trials involving 139 participants were included. The primary outcome measure in each was pain relief. Three trials with an unclear risk of bias compared one of the non-antiepileptic drugs tizanidine, tocainide or pimozide with carbamazepine. In a trial of tizanidine involving 12 participants (one dropped out due to unrelated disease) one of five treated with tizanidine and four of six treated with carbamazepine improved, risk ratio 0.30 (95% CI 0.05 to 1.89). Few side effects were noted with tizanidine. In a study involving 12 participants there was an improvement in mean pain scores with tocainide similar to that with carbamazepine, but significant side effects limited its use. In the pimozide study more participants improved on pimozide (48/48) than with carbamazepine (27/48) (risk ratio 1.76, 95% CI 1.37 to 2.26). Up to 83% of participants reported adverse effects but these did not lead to withdrawal from the study.

Spasticity is one of the clinical signs observed after a lesion of the pyramidal tract. Clinical manifestations are polymorphous and depend on the location of the lesion on the pre-motoneuron. Functional consequences are also variable. Only negative effects such as painful spasms, stiffness, distortions, are to be treated. Three different categories of drugs are available: GABA-like (baclofen, benzodiazepine), central alpha 2 agonists (tizanidine, clonidine) and peripheral anti-spastics (dantrolene). Baclofen remains the most commonly used anti-spastic. The preferential indication is spasticity from spinal cord disease, especially when the aetiology is multiple sclerosis. Efficacy of benzodiazepines (diazepam, tetrazepam, clonazepam) is comparable with baclofen; however, side effects (drowsiness) are more frequent. Benzodiazepines are indicated when spasticity is associated with anxiety. Tizanidine is an efficient and well tolerated antispastic. In France, prescription requires a temporary authorization of use. Dantrolen has a peripheral mechanism of action and can be prescribed in the different forms of spasticity. There are other compounds with anti-spastic properties (gabapentine, cyproheptadine, piracetam). Their buy zanaflex advantage is rather limited when used alone. Generally, they are administrated in combinaison with usual anti-spastic drugs.

Tizanidine is a centrally acting alpha-2 adrenoreceptor agonist widely used in the treatment of spasticity in patients with cerebral or spinal injury, and it is causing drawsiness in some of them. Based on these drug actions, we administered tizanidine to 21 spastic quadriplegic children with severe sleep disturbance buy zanaflex not improved by conventional therapies. All these patients were showing abnormalities of both the induction and maintenance of sleep. The dosage of tizanidine was 0.1 to 0.2 mg/kg/day, divided into two or three doses. If daytime drowsiness was severe, tizanidine admistration was restricted to just prior to bedtime. In 13 patients (61.9%), we found improvement in sleep induction and/or maintenance. Moreover, patients' families were satisfied with the treatment. There were no detectable side effects except facial pallor in two patients (9.5%) whose treatment was discontinued. Severe muscle hypertonia causes severe pain, which generates strong sympathetic nerve activity and subsequent sleep disturbance. We consider that tizanidine has direct effects on the induction of sleep, and promotes muscular relaxation bringing about good sleep. We conclude that tizanidine is useful for the treatment of refractory sleep disturbance in spastic quadriplegic patients.

Tizanidine and aceclofenac individually have shown efficacy in the treatment of low back pain. The efficacy and tolerability of the combination have not yet been established. The objective of the study was to evaluate the efficacy and safety of aceclofenac-tizanidine fixed dose combination against aceclofenac alone in patients with acute low back pain. This double-blind, double-dummy, randomized, comparative, multicentric, parallel group buy zanaflex study enrolled 197 patients of either sex in the age range of 18-70 years with acute low back pain. The patients were randomized to receive either aceclofenac (100 mg)-tizanidine (2 mg) b.i.d or aceclofenac (100 mg) alone b.i.d for 7 days. The primary efficacy outcomes were pain intensity (on movement, at rest and at night; on VAS scale) and pain relief (on a 5-point verbal rating scale). The secondary efficacy outcomes measures included functional impairment (modified Schober's test and lateral body bending test) and patient's and investigator's global efficacy assessment. aceclofenac-tizanidine was significantly superior to aceclofenac for pain intensity (on movement, at rest and at night; P < 0.05) and pain relief (P = 0.00) on days 3 and 7. There was significant increase in spinal flexion in both the groups from baseline on days 3 and 7 with significant difference in favour of the combination group (P < 0.05). There were significantly more number of patients with excellent to good response for the aceclofenac-tizanidine treatment as compared to aceclofenac alone (P = 0.00). Both the treatments were well tolerated. In this study, aceclofenac-tizanidine combination was more effective than aceclofenac alone and had a favourable safety profile in the treatment of acute low back pain.

The pharmacokinetics of tizanidine, a new centrally acting muscle relaxant, have been studied in 18 normal male volunteers who received orally a single 5 mg dose, a single 20 mg dose, or repeated administration of 4 mg every 8 hr for 13 doses of [14C]tizanidine. Serial blood and breath samples and complete urine Tegretol Drug Interactions and feces were collected and analyzed for total radioactivity as well as intact tizanidine. Tizanidine was rapidly and almost completely absorbed from the gastrointestinal tract, although the estimated bioavailability was only 21% due to extensive first-pass metabolism. The pharmacokinetics of tizanidine appeared to be linear in the 0-20 mg dose range, as indicated by the dose-proportional blood levels of total radioactivity as well as of parent drug. Absorbed tizanidine was almost completely metabolized before excretion, the major excretory route being via the kidneys. The terminal half-lives of tizanidine and radioactivity were ca 3 hr and 61 hr, respectively, and 76%-77% of the administered radioactivity was recovered within 120 hr. Repeated administration of [14C]tizanidine resulted in no apparent change in pharmacokinetic characteristics. During the 4 mg q 8 hr regimen, blood levels of tizanidine reached steady state after only 2 or 3 doses, whereas those of total radioactivity approached steady state after approximately 4 days. The degree of accumulation of radioactivity, unlike that of parent drug, was inconsistent with the terminal half-life, but instead implied a shorter effective half-life of ca. 16 hr. It appears that the terminal phase of the blood radioactivity profile represents a metabolite that is reversibly bound to and slowly released from a specific tissue depot, and that this binding involves a finite amount of drug regardless of the dose. The oral administration of [14C]tizanidine prescribed in the present study was safe and well tolerated.

Spasticity is one of the most common motor and tonus disorders during the initial phase Triphala Tablets Patanjali with traumatic brain injured patients. The evaluation of spasticity is mainly clinical but it is very important to prevent complications such as limitation of range of motion, pain, decubitus ulcers. The therapeutic options consist in classical indications such as baclofen, dantrolene, tizanidine, benzodiazepine, associated with physiotherapy. Other additive therapeutic options could be discussed: use of toxin botulinum in focal spasticity and intrathecal baclofen infusion in case of severe spasticity (often associated with dysautonomic disorders.).

This series of articles for rehabilitation in practice aims to cover a knowledge element of the rehabilitation medicine curriculum. Nevertheless they are intended to be of interest to a multidisciplinary audience. The competency addressed in this article is 'The trainee consistently demonstrates a knowledge of the pathophysiology of various specific impairments including spasticity'. Spasticity is an extremely common feature of chronic neurological conditions and, if badly managed, it can result in pain, contractures and pressure sores, all of which can impact on function. It is therefore essential that a multidisciplinary management strategy is in place to help the individual manage their particular situation through education with timely access to interventions including instigation of a physical management programme and medication such as baclofen Flagyl No Alcohol , tizanidine, dantrolene, benzodiazepines and gabapentin. Further treatment options for focal spasticity are botulinum toxin and phenol nerve blocks or intrathecal baclofen or phenol for predominant lower limb spasticity. Ongoing assessment with the use of appropriate outcome measures can both guide choice of treatment and monitor efficacy.

Early and late facilitation of the Reglan Max Dose quadriceps H reflex elicited in the common peroneal nerve--attributed to non-monosynaptic group I and group II excitation, respectively--was investigated in 14 spastic hemiplegic patients. All received a single dose of tizanidine (150 microg/kg) or placebo in randomised order at 10 day intervals. Repeated measurements were made at baseline (T0), 45-90 min, and 120 min after drug intake. Spasticity was assessed by modified Ashworth score in the quadriceps muscle and by a leg tone score calculated by the sum of the modified Ashworth score in five muscle groups.

Sixty patients affected by chronic LBP associated with contractures of paravertebral muscles were randomized in two groups: Group E (30 patients) treated with eperisone; Group T (30 patients) treated with tizanidine. Both groups received tramadol retard 100 mg/day Accutane Dosage Calculator . VAS at rest and with effort were used at baseline (T0) and after 5 (T5), 10 (T10), 15 (T15) and 30 (T30) days of treatment. The Summed Pain Intensity Difference (SPID), the SPID percentage (SPID%) and the Total Pain Relief (TOTPAR), at rest (-r) and with effort (-e) were calculated.

Cervical facet joint (CFJ) syndrome is a common disorder observed in chronic pain of the cervical region, especially in long-standing myofascial pain syndrome (MPS). This study aimed to Luvox Reviews 2013 investigate the effects of therapeutic CFJ injections on patients with long-standing cervical MPS with referral pain patterns of CFJ syndrome.

Microinjection of tizanidine into the substantia nigra pars reticulata or entopeduncular nucleus reduces muscle tone in genetically spastic rats Seroquel 450 Mg . The effect of tizanidine is related to alpha 2-adrenergic mechanism since yohimbine, an alpha 2-adrenergic antagonist, and not prazosin, an alpha 1-adrenergic antagonist, attenuates the muscle relaxation produced by the drug. These results signify basal ganglia output stations as possible sites whereby tizanidine acting via alpha 2-adrenergic mechanism exerts its muscle relaxant action.

The effects of intravenous clonidine and tizanidine on nociceptive neurons in the nucleus ventralis posterolateralis (VPL) of the thalamus, a key station in the lateral system of ascending pain pathways, were evaluated in urethane-chloralose anesthetized cats. Intravenous clonidine and tizanidine produced a dose-dependent (5 and Cipro 500mg Dosage 10 micrograms/kg, and 25 and 50 micrograms/kg, respectively) suppression of responses of nociceptive specific (NS) and wide dynamic range (WDR) neurons in the VPL to high threshold splanchnic input. In contrast, the responses of both NS and WDR units to electrical stimulation of spinothalamic tract fibers in the ventrolateral funiculus (VLF) were little affected. We conclude that a site of suppressive action of the alpha 2-adrenoceptor agonists, as observed in nociceptive VPL neurons, is at the level of the spinal dorsal horn rather than in the VPL itself.

Twenty-six placebo-controlled studies (using baclofen, dantrolene, tizanidine, botulinum toxin, vigabatrin, prazepam, threonine and cannabinoids) and thirteen comparative studies met the selection criteria and were included in this review. Only fifteen of these studies used the Ashworth scale, of which only three of the eight placebo-controlled trials and none of the seven comparative studies showed a statistically significant Zanaflex Normal Dose difference between test drugs. Spasms, other symptoms and overall impressions were only assessed using unvalidated scores and results of functional assessments were inconclusive.
