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.

Myofascial pain syndrome (MPS) is difficult to treat. The efficacy and safety of tizanidine, an alpha2-adrenergic agent with effects on spasticity and pain, in treating MPS was evaluated. Female subjects (n = 29) with MPS of 9 to > 52 weeks' duration and mean age 37.5 (range 20-51) years, who also had reduced pressure thresholds, were enrolled. Subjects were titrated up to 12 mg of tizanidine over 3 weeks and maintained for 2 weeks. Sleep was assessed via visual analog scale (VAS), pain intensity via short form McGill questionnaire including VAS, disability/level of function, and pressure threshold (tested by algometry) at baseline, weeks 3 and 5, and 1 week after tizanidine was discontinued. Patient and physician global assessments of treatment were reported at week 5. Twenty-four subjects completed the study. Pain intensity and disability decreased significantly from baseline at weeks 3 and 5 and after washout (P < .001). Pressure threshold and sleep improved for all study periods (P < .001). Tizanidine was rated as good to excellent in relieving pain by 89% of subjects and 79% of physicians. No serious adverse events occurred. Tizanidine was effective in the treatment of MPS.

Continuous intrathecal baclofen has been used over the past years especially in adult patients with spasticity of spinal origin. Children and young adults with severe spasticity and dystonia of cerebral origin are difficult to treat in spite of optimal systemic antispasmotic therapy with baclofen, tizanidine, dantrolene and/or diazepam. Intrathecal baclofen has therefore been applied in a group of young patients.

There was a linear relationship between different dosages of intranasal formulation and the area under the concentration-time curve and maximum plasma concentration (C(max)). The relative bioavailability of the different dosages of intranasal formulation were 1.29, 1.93, and 4.23 for 1, 2, and 4 mg intranasal administration, respectively. Comparison of C(max) values gave the following ratios: 0.91, 1.39, and 2.73, for 1, 2, and 4 mg intranasal administration, respectively. The mean time to C(max) (t(max)) was 0.99, 0.43, and 0.63 h for 1, 2, and 4 mg intranasal administration, respectively, whereas it was 1.13 and 1.30 h for the two series of 4 mg tizanidine oral tablets.

Incubation of tizanidine (80 nm) with human liver microsomes resulted in time- and NADPH-dependent substrate consumption with a half-life of 50 min, initial reaction velocity of 1.1 pmol x min-1 x mg-1 protein and intrinsic clearance of 17 ml x min-1 x kg-1. The predicted in vivo hepatic clearance (CLh) of tizanidine using the well-stirred and parallel-tube model was close (68% and 82%, respectively) to its estimated in vivo CLh. Fluvoxamine and furafylline strongly inhibited tizanidine metabolism. Inhibitors specific to isoforms other than CYP1A2 had no substantial effect. Recombinant CYP1A2 metabolized tizanidine to a substantial degree (35% in 45 min), but other recombinant CYPs had little metabolic capacity for the drug.

Clonus is an involuntary rhythmic muscle contraction after sudden muscle stretch that occurs as a result of a lesion in the upper motor neurons. The real mechanism behind clonus remains obscure. The objective of this study was to investigate the effects of central-acting tizanidine treatment and peripheral extremity cooling on clonus.

Our findings demonstrate that tizanidine acts to reduce reflex mechanical responses substantially, without inducing comparable changes in intrinsic muscle properties in individuals with spinal cord injury. Thus, the pre-post difference in joint mechanical properties can be attributed to reflex changes alone. From a practical standpoint, use of a single "test" dose of Tizanidine may help clinicians decide whether the drug can helpful in controlling symptoms in particular subjects.

1. In standing humans, toe-up rotation of a platform induces a short-latency (SLR) and a medium-latency response (MLR) in both soleus (Sol) and flexor digitorum brevis (FDB) muscles. Toe-down rotation evokes a MLR in the tibialis anterior (TA). The SLR is the counterpart of the monosynaptic stretch reflex, but the origin of the MLR is still debated. By means of tizanidine (an alpha 2-adrenergic receptor agonist) we tested the hypothesis that the MLR is relayed by group II afferent fibres, since animal data indicate that tizanidine or stimulation of monoaminergic brainstem centres decrease the excitability of spinal interneurones supplied by those fibres. In addition, we compared the effect of the drug on these responses with that induced by stabilization of posture. 2. Eight subjects received tizanidine (150 micrograms kg-1 orally) or placebo, in a single-blind design. Platform rotations were delivered prior to administration and for 3 h afterwards. Both TA- and FDB-MLRs decreased in size, starting from about 1 h after tizanidine administration. Sol-SLR was unaffected. Response latencies were unchanged. Placebo induced no changes in any response. In each subject, the extent of TA-MLR depression induced by holding onto a frame and by tizanidine was superimposable. 3. The selective effect of tizanidine on MLR supports the notion that it is relayed through group II afferent fibres. The similar effects of holding and tizanidine on the response suggests that it is modulated by monoaminergic centres.

The availability of new antispasticity agents has greatly extended the therapeutic arm of the neurologist and has obviated the need for destructive neurosurgical procedures in many instances. Baclofen remains the single most useful agent, but in certain circumstances, benzodiazepines and dantrolene sodium are useful alternative or adjunctive treatments. Tizanidine has been recently introduced, and early experience with this agent appears to be favourable. A variety of new drugs are awaiting further evaluation. The effective use of these agents demands an understanding of their principal mechanisms of action, knowledge of their predictable side effects, and a familiarity with the underlying neurological disorders. The monitoring of clinical efficacy is difficult and is often dependent upon subjective evaluation. The application of electrophysiological studies might facilitate the monitoring of treatment and the prediction of optimum treatment strategies for individual patients. The use of these pharmacological agents, from the perspective of a clinician, will be discussed.

Forty-two patients, including 23 females and 19 males, with failed back surgery syndrome who had been previously operated on at least twice due to lumbar disc herniation were randomly divided into two groups. Following epidural application of a single dose of methylprednisolone in the first group of patients (Group K), an oral medical treatment containing naproxen sodium, tizanidine, and vitamin B and C complex, was devised to be applied for one month. For the second group, oral gabapentin was added to the same treatment regime (Group G). Pain levels were evaluated by a visual analog scale for straight leg raise before, during, and after treatment, as well as in the first and third months.

There was no demographically significant difference between the patients (P > 0.05). After the beginning of treatment, it was observed that the pain level in Group G patients regressed earlier and that it progressed at a significantly lower level (both in the first and third month controls).

The intrathecal alpha2-adrenergic agonist, clonidine, has been shown to have considerable antinociceptive effect, although clonidine causes hypotension and bradycardia. The combination of intrathecal clonidine and local anesthetics enhances analgesic effects, whereas the combination may cause marked hypotension and motor blockade, which may limit the clinical application of the combination. Tizanidine, another alpha2-adrenergic agonist, has also provided antinociception without producing pronounced hemodynamic changes. This study was designed to evaluate the antinociceptive and hemodynamic interactions of tizanidine and clonidine with lidocaine.

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 advantage is rather limited when used alone. Generally, they are administrated in combinaison with usual anti-spastic drugs.

Spasticity is a disabling complication of multiple sclerosis. Some commonly used oral medications include baclofen, tizanidine, anticonvulsants and benzodiazepines, but their benefits are modest. Sativex® (GW Pharmaceuticals PLC, Porton Down, UK; Laboratorios Almirall, SA, Barcelona, Spain) is a unique cannabinoid-based medicine with two main active ingredients; 9-δ-tetrahydrocannabinol, which acts mainly on cannabinoid 1 receptors in the CNS and plays a key role in the modulation of spasticity and spasms, and cannabidiol, which has different properties, including minimization of the psychoactivity associated with 9-δ-tetrahydrocannabinol. Sativex is indicated for symptomatic improvement in adult patients with moderate-to-severe multiple sclerosis-related spasticity who have not responded adequately to other first- or second-line antispasticity medications, and who demonstrate clinically significant improvement in spasticity-related symptoms during an initial trial of therapy. Over the past couple of years, Sativex has been approved for use in a number of European countries and ongoing postmarketing studies are evaluating the possible risks associated with Sativex treatment by systematically collecting all suspected adverse reactions that occur in patients from the start of treatment. Interim data from the UK as well as Spanish Sativex safety registries confirm that clinical benefit is maintained over the longer term despite the expected trend for deterioration owing to disease progression. Even after more than 2 years of use, no new safety/tolerability signals have emerged with Sativex, including no evidence of driving impairment and no relevant incidence of falls or other adverse events of concern, such as psychiatric or nervous system events. Sativex appears to be a well-tolerated and useful add-on therapy in patients who have not achieved an adequate response with traditional antispastic agents.

Among the 11 muscle relaxant compounds tested (tolperisone, eperisone, silperisone, diazepam, baclofen, tizanidine, afloqualon, mephenesin, zoxazolamine, memantine and carisoprodol), the calculated safety ratios (i.e. ID50 for side effect/ID50 for muscle relaxant effect) varied in a wide range. Silperisone seems to have the most advantageous profile (safety ratios range between 1.7 and 3.3 in the different pairs of assays) compared to the other tested drugs with lower (one or more ratios below 1.5, and often far below 1) and more varying ratios.

Tizanidine, an alpha-2 adrenergic agonist, is a centrally active muscle relaxant and a spasmolytic drug. The aim of our study was to investigate the activity of tizanidine on maximal electroshock seizures (MES) in mice. In the first part of the study, convulsive current 50 (CC 50) value to produce seizures was found buy zanaflex . Then, tizanidine was given intraperitoneally (IP) at the doses of 0.5, 1, and 2 mg/kg, and orally (PO) at the doses of 5, 10, 20, 40 mg/kg. We found that tizanidine at the doses of 1 and 2 mg/kg IP and 40 mg/kg PO caused a significant protection against MES. In the second part of the study, after pretreatment with yohimbine, an alpha-2 adrenergic receptor blocker, at the dose of 2 mg/kg, anticonvulsant effect of tizanidine is diminished. We concluded that the mode of action of the anticonvulsant effect of tizanidine may be mediated by the central alpha-2 adrenergic receptors.

Microsomal and crude synaptosomal fractions were prepared from the longitudinal muscle of guinea-pig ileum. A specific binding of [3H]yohimbine (10 nM) to alpha 2-adrenoceptor in the crude synaptosomal fraction was inhibited by tizanidine and clonidine. Tizanidine is about one-third as potent as clonidine. A specific binding of [3H]QNB (0.3 nM) to muscarine receptor in the microsomal fraction was inhibited by atropine (10(-8)-10(-7) M) but not by tizanidine (up to 10(-4) M). Tizanidine inhibited buy zanaflex spontaneous movements of guinea pig ileum and rat stomach (in situ) and intestinal transit in mice, and induced mydriasis in mice. These effects induced by tizanidine might be due to activation of alpha 2-adrenoceptor but not to atropine like action.

Experiments in cats anesthetized with alpha-chloralose showed that tizanidine (TZD: 5-chloro-4-(2-imidazolin-2-yl-amino)-2,1,3-benzothiodiazole) partly resembled carbamazepine (CBZ) and baclofen (BCF) in that it depressed excitatory transmission and facilitated segmental inhibition of neurons in the spinal trigeminal nucleus oralis which responded to tapping but did not affect the response of neurons which responded to light stroking of the skin or bending the whiskers. In a double-blind crossover study of TZD in refractory trigeminal neuralgia, 8 of 10 patients had fewer painful paroxysms while on TZD. However, the 6 patients who elected to continue taking TZD experienced a recurrence of their attacks of trigeminal neuralgia within 1-3 months. The limited efficacy of TZD buy zanaflex in the treatment of trigeminal neuralgia may be related to the fact that it has no effect on neuronal responses to low-threshold mechanoceptive stimuli, suggesting that low-threshold mechanoceptive neurons play an important role in the pathogenesis of trigeminal neuralgia.

In a patient with the stiff-man syndrome, abnormal exteroceptive reflexes in hand and arm muscles were used as a tool for investigating the effects of various centrally acting adrenergic drugs by means of acute testing. Clonidine, tizanidine and methamphetamine induced reflex suppression whereas reserpine had a biphasic effect: transient reflex suppression and delayed reflex enhancement. The drug actions on the reflexes paralleled to some degree those on the muscle stiffness. It is buy zanaflex concluded that alpha-adrenergic stimulation leads to reflex suppression and muscular relaxation, whereas alpha-adrenergic blockade has the opposite effect. Correspondingly, long-term oral treatment with the alpha-stimulator, tizanidine, proved successful. The hypothesis is put forward that a noradrenergic system which exerts a net inhibitory influence on muscle tone and on exteroceptive reflexes plays an important role in the pathogenesis of the stiff-man syndrome.

Abrupt cessation of intrathecal baclofen ( buy zanaflex ITB) administration can cause a life-threatening withdrawal syndrome that requires prompt diagnosis and urgent treatment. The current therapy for this condition is administration of propofol, benzodiazepines, paralytics and supportive care. This study reports a 53-year-old patient with paraplegia with an ITB infusion who presented with an infected pump site. The pump and the catheter were surgically removed and replaced with a temporary externalized intrathecal catheter. The ITB infusion was tapered and simultaneously substituted with progressively higher doses of oral antispasmotics. With this strategy, we were able to avoid life-threatening complications.

Data from three placebo-controlled and 11 active-controlled studies of tizanidine were combined to permit analysis of the subsets, which were too small to evaluate within the individual studies. Overall analysis of placebo-controlled data confirms the effectiveness of tizanidine in reducing muscle tone in patients with spasticity of spinal cord origin. Subset analyses suggest that patients with more severe spasticity are more likely to respond buy zanaflex , but age, sex, and race were not predictive of response. Comparisons of tizanidine with active controls showed no differences in efficacy compared with baclofen or diazepam. However, when compared with controls, patients treated with tizanidine did not experience increased weakness. Furthermore, patients tolerated tizanidine better than the control medications. More patients experienced adverse events during tizanidine treatment than did patients receiving placebo. The most common adverse events reported were dry mouth, somnolence, asthenia, and dizziness. Mild elevations in liver function tests were noted occasionally, but improved in all patients with dose reduction or withdrawal. Three patients from the double-blind database reported formed visual hallucinations. All three cleared; two continued tizanidine, and one discontinued.

An efficient gas chromatography-mass spectrometry (GC-MS) method was developed and validated for the determination of tizanidine in human Lexapro Drug Interactions plasma. Plasma samples were simply extracted with ethyl acetate at basic pH and the extracts were converted into trimethylsilyl (TMS) derivatives for direct separation by GC-MS with selected ion monitoring (SIM). Reaction of tizanidine with N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) caused di-trimethylsilylation in the imidazoline moiety and this silylation significantly improved the chromatographic properties of the compound. The determination of tizanidine was accurate and reproducible, with a limit of quantitation of 0.5 ng m(-1) in plasma. The calibration curve for tizanidine was linear (r2 = 0.999) over the concentration range 0.5-10.0 ng ml(-1) in human plasma. The intra- and inter-day precision over the concentration range of tizanidine was well within 6.9% (relative standard deviation) and the accuracy was between 99.2 and 110.5%.

The selectivity of tizanidine to the imidazoline-receptor and alpha 2-adrenoceptor recognized by 3H-p-aminoclonidine was examined in rat kidney membranes and was compared with those of other imidazoline compounds. Tizanidine bound to the imidazoline-receptors with approximately 20 times higher affinity than the alpha 2-adrenoceptors. The order of relative selectivity to imidazoline receptor was tizanidine greater than oxymetazoline greater than clonidine greater than naphazoline, where clonidine showed an Diovan Normal Dose equal affinity to both receptors. Tizanidine may act more potently on the imidazoline-receptors than the alpha 2-adrenoceptors.

We studied the effects of robotic-assisted locomotor (LOKOMAT) training or an anti-spastic medication (tizanidine) on neuromuscular abnormality associated with spasticity in persons with incomplete Spinal Cord Injury (SCI). Subjects were randomly divided to three groups: Lok, Tiz, and Cont. LOKOMAT training was performed 3 days/week for 4 weeks, with up to 45 minutes of training per session. Tizanidine (2mg) was administered (4\day), for 4 weeks. Subjects in Cont group received no intervention. The participants were evaluated before and after 4 weeks of training, and the effects of training on the intrinsic (muscular) and reflexive components of the neuromuscular properties were quantified over the ankle range-of-motion. A parallel-cascade system identification technique was used to determine the reflex and intrinsic stiffness of the ankle joint as a function of ankle position at each time point. The intercept and slope of the stiffness vs. joint angle curve were then calculated and tracked over the four-week period. The number of subjects that achieved the minimally important difference (MID) for the intercepts and slopes, and levels of changes were compared. Both Lokomat and tizanidine resulted in significant reduction in both intercept and slope of reflex and intrinsic stiffness. However, a higher proportion of subjects in Cymbalta Maximum Dosage Lok group achieved the MID for the reflex (>90%) and intrinsic (65-78%) parameters compared with Tiz group (up to 63% and 25% for reflex and intrinsic parameters, respectively). The levels of reduction were also higher in the Lok than the Tiz group. No one in the Cont group achieved the MID. Our findings demonstrate that LOKOMAT training can be more efficient in modifying neuromuscular abnormalities associated with spasticity than tizanidine.

A total of 44 patients Augmentin Highest Dosage with U-MND were referred for discussion of ITB therapy. Baseline and outcomes data were extracted on 35 patients from a clinical spasticity registry at a tertiary referral center. Patients choosing to initiate ITB (n = 20) were compared with those choosing conservative therapy (n = 15).
