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.

In a double blind, randomised, multicentre trial 22 patients were followed up during 13 weeks and subsequently included in a 52 week observational longitudinal study. Patients were those with chronic, disabling spasticity who did not respond to maximum doses of oral baclofen, dantrolene, and tizanidine. After implantation of a programmable pump patients were randomly assigned to placebo or baclofen infusion for 13 weeks. After 13 weeks all patients received baclofen. Clinical efficacy was assessed by the Ashworth scale, spasm score, and self reported pain, and health related quality of life by the sickness impact profile (SIP) and the Hopkins symptom checklist (HSCL).

Clonidine is a partial agonist at brain alpha(2)-adrenoceptors (alpha(2)AR), but also has high affinity (K(D) = 51 nM) in homogenate binding assays for non-adrenergic imidazoline-binding sites (I-sites; imidazoline receptors). Herein, an autoradiographic comparison of [3H]-clonidine binding to I-sites and alpha(2)AR in sections of human brain is reported. For I-sites, the adrenergic component of 50 nM [3H]-clonidine binding was masked with either 60 microM norepinephrine (NE; alpha(2)AR agonist) or 12.5 microM methoxy-idazoxan (MIDX; selective alpha(2)AR antagonist), whereas the remaining non-adrenergic sites were studied by displacement with 20 microM cirazoline. Levels of [3H]-clonidine binding to alpha(2)AR and I-sites, determined in adjacent tissue sections, were positively correlated across 27 brain regions (p = 0.0003; r(2) = 0.385). The principal olivary nucleus and the rostral portion of the ventrolateral medulla had highest ratios of I-sites: alpha(2)AR (>4:1). Quantitative transepts drawn across hippocampal images revealed alpha(2)AR enrichments in the CA-1 and inner molecular layers of the dentate gyrus-areas not enriched in I-sites. Competition curves were generated for I-sites in caudate sections using 10 ligands known to distinguish between I(1) and I(2) subtypes. The rank-order of affinities were cirazoline > harmane > BDF6143 > idazoxan = tizanidine (affinities of agmatine, efaroxan, moxonidine, NE, and oxymetazoline were too low to be reliable). Only the endogenous I-site ligand, harmane, had a monophasic displacement curve at the non-adrenergic sites (Ki = 521 +/- 12 nM).

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 difference between test drugs. Spasms, other symptoms and overall impressions were only assessed using unvalidated scores and results of functional assessments were inconclusive.

This is a case which highlights unique diagnostic challenges in the evaluation of a previously healthy patient presenting with a myelopathy initially most concerning for malignancy. However, timely recognition and nonoperative therapy of unexpected spinal sarcoidosis with corticosteroidal therapy was crucial in averting the sequelae of undiagnosed or misdiagnosed neurosarcoidosis, which can be devastating and life-threatening. Diagnosis is challenging due to significant similarities in clinical and roentgenographic findings of spinal sarcoidosis with infection, inflammation, and malignancy. Our case demonstrates that diagnosis of spinal sarcoidosis is especially elusive when it is the initial manifestation of sarcoidosis.

Comparator studies that assess treatment effects in a clinical setting have improved the understanding of the efficacy and tolerability of prophylactic treatments for chronic migraine (CM). It is premature to recommend device-based treatments, such as occipital nerve stimulation, vagal nerve stimulation, and patent foramen ovale closure for CM, because clinical trials are in the preliminary stages. Physical therapy techniques, like applying heat or cold packs, ultrasonography, and electrical stimulation, have been shown to lessen pain. Nonpharmacologic treatments, including cognitive behavioral therapy, stress management, and biofeedback, have been investigated and proved effective in some areas of pain management, including migraine. However, pharmacologic interventions may be necessary for effective, long-term prophylaxis. Several medications under investigation, including topiramate, gabapentin, tizanidine, and amitriptyline, have proved efficacious in reducing the number of migraine episodes and the pain associated with migraine, although adverse events may prevent continued use of some agents. Evidence supports the use of botulinum toxin type A (BoNT-A) for CM, with or without medication overuse, to achieve a significant reduction in headache episodes. Efficacy of BoNT-A for CM is comparable with or better than that of valproate and topiramate, with better tolerability. Predictors of response to BoNT-A for CM appear to include predominantly unilateral location of the headache and the presence of cutaneous or muscle allodynia. BoNT-A has been demonstrated to be safe and well tolerated, with rare discontinuations due to adverse events. Recent clinical trials indicate that rational combination therapy may have a place in treating refractory CM. Well-controlled multicenter trials are awaited.

Glutamic and aspartic acids are the physiological mediators of most excitatory synaptic transmission. This is critical to several normal nervous system functions, including memory and long-term modification of synaptic transmission and nociception. Activation of the inotropic NMDA and non-NMDA receptors increases transmembrane calcium and sodium fluxes, and the metabotropic glutamate receptor activation results in generation of inositol triphosphate and inhibition of adenylate cyclase. Numerous modulatory sites exist, especially on the NMDA receptor. Nitric oxide, arachidonic acid, superoxide, and intracellular calcium overload are the ultimate mediators of neuronal death. Glutamate re-uptake transporters belong to a unique family of amino acid transport systems, the malfunction of which is intricately involved in disease pathogenesis. Ischemic stroke, hypoglycemia, Parkinson's disease, alcohol intoxication and withdrawal, Alzheimer's disease, epilepsy, and chronic pain syndromes are only some of the important clinical neurological disorders with a major pathogenic role for the excitatory amino acids.

Tension-type headache (TTH) is the most prevalent form of primary headache in the general population. We discuss advances in the treatment of TTH. We briefly review nonpharmacologic therapies and then focus on current pharmacologic strategies. For acute treatment, the most common interventions involve the use of simple analgesics and anti-inflammatory medications, often taken by the patient without a prescription. For preventive treatment, amitriptyline is the best-studied drug, but nortriptyline, mirtazapine, tizanidine, the selective serotonin reuptake inhibitors, and other medications can be used. We close by discussing potential future therapies, including calcitonin gene-related peptide receptor antagonism, as well as substance P and the nitric oxide pathways.

Tizanidine (Sirdalud) was compared to baclofen (Lioresal) in a randomized, double-blind, cross-over trial. Each medication was introduced over a three week titration period and then maintained at the highest tolerated dose for five weeks. The two treatment phases were separated by a one week drug withdrawal and a two week washout period. Sixty-six patients entered the trial and forty-eight completed both treatment phases. At the end of the trial, neurologists and physiotherapists thought that baclofen was superior on the basis of perceived efficacy and tolerance (p less than or equal to 0.05). Although the efficacy of tizanidine or baclofen was judged as good to excellent by 24 and 39% of patients respectively, this difference was not statistically significant. Muscle weakness was the most common adverse effect. This was significantly more troublesome in patients treated with baclofen. Somnolence and xerostomia were more common in patients treated with tizanidine. Both baclofen and tizanidine appear to be useful adjuncts in the treatment of spasticity in patients with multiple sclerosis. Preference of either drug is tempered principally by side-effects.

Tizanidine, an alpha(2)-adrenoceptor agonist, is a short-acting drug with larger interpatient variability, and linear pharmacokinetics that is dosage form-dependent. Clinical trials have demonstrated that the efficacy of tizanidine is comparable to that of baclofen or diazepam with global tolerability data favoring tizanidine. A clinical case presentation demonstrated the effective use of tizanidine in combination with baclofen as a logical avenue for improved spasticity control.

A comprehensively validated procedure is presented for simultaneous semiquantitative/quantitative screening of 51 drugs of abuse or drugs potentially hazardous for traffic safety in serum, plasma or whole blood. Benzodiazepines (12), cannabinoids (3), opioids (8), cocaine, antidepressants (13), antipsychotics (5) and antiepileptics (2) as well as zolpidem, zaleplon, zopiclone, meprobamate, carisoprodol, tizanidine and orphenadrine and internal standard flurazepam, were isolated by high-yield liquid-liquid extraction (LLE). The dried extracts were derivatized by two-step silylation and analyzed by the combination of two different gas chromatographic (GC) separations with both electron capture detection (ECD) and mass spectrometry (MS) operating in a selected ion-monitoring (SIM) mode. Quantitative or semiquantitative results were obtained for each substance based on four-point calibration. In the validation tests, accuracy, reproducibility, linearity, limit of detection (LOD) and limit of quantitation (LOQ), selectivity, as well as extraction efficiency and stability of standard stock solutions were tested, and derivatization was optimized in detail. Intra- and inter-day precisions were within 2.5-21.8 and 6.0-22.5%, and square of correlation coefficients of linearity ranged from 0.9896 to 0.9999. The limit of quantitation (LOQ) varied from 2 to 2000 ng/ml due to a variety of the relevant concentrations of the analyzed substances in blood. The method is feasible for highly sensitive, reliable and possibly routinely performed clinical and forensic toxicological analyses.

Tolfenamic acid strongly inhibited phenacetin-O-deethylation in vitro (IC(50) 1.8 microM without albumin). Albumin decreased its inhibitory effect in a concentration-dependent manner; the IC(50) exceeded 100 microM with 10 mg/ml of albumin. Tolfenamic acid had no effect on the area under the concentration-time curve (AUC(0-oo)), peak concentration, time of peak concentration or half-life of tizanidine or M-3; only the AUC(0-oo) of secondary metabolite M-4 was slightly decreased (13%, P = 0.004). The caffeine test and the pharmacodynamic effects of tizanidine were unchanged.

Alpha-2-adrenergic agonists, such as clonidine, produce antinociception in animal pain models after intrathecal administration. However, clinical usage is limited by cardiovascular side effects. To investigate alternative alpha(2)-adrenergic agonists as analgesics, we implanted six dogs with an intrathecal catheter and infusion pump. After baseline saline infusion, animals received clonidine or tizanidine (crossover study) each week at escalating doses of 125-750 microg/h. Analgesia, blood pressure, heart rate, respiratory rate, sedation, and coordination were evaluated. A 28-day safety study was performed with another nine dogs receiving intrathecal tizanidine (3 or 6 mg/d) or saline. Equal doses of clonidine and tizanidine produce the same antinociception in thermal withdrawal tests. Blood pressure was reduced with 125-500 microg/h of clonidine, but not with tizanidine at any dose. Clonidine 250 microg/h reduced heart rate by 45.8%, and five of six animals had bradyarrhythmias (marked bradycardia), whereas tizanidine decreased heart rate by 15.1% without arrhythmias, even at the largest dose. Respiratory rate decreased with 250 microg/h of clonidine and larger doses. Sedation or incoordination occurred only at the largest dose for either drug. The safety study indicated that 3 mg/d of tizanidine in dogs produced no side effects or histopathologic changes. Tizanidine may be a useful alternative in patients experiencing cardiovascular side effects with intrathecal infusion of clonidine.

zanaflex reviews

Spasticity and other muscle symptoms in the palliative care patient can contribute to suffering, significantly detracting from overall quality of life. Current therapy primarily includes use of centrally acting muscle relaxants, which are beneficial in treating some symptoms, but frequently have extensive side effects, such as sedation and muscle weakness. Tizanidine, a central alpha 2 adrenergic agonist, has been shown in clinical studies to be as effective as other commonly used antispastic agents, but without debilitating muscle weakness. Tizanidine can cause sedation, which is minimized by dose titration. When taken at night, patients report improvement in getting to sleep and little drowsiness or "hangover sensation" upon waking. Tizanidine is potentially helpful to many palliative care patients with chronic muscle pain and sleep disturbances.

The centrally acting muscle relaxant baclofen (3-10 mg/kg) reduced SR induced by morphine (40 mg/kg) at all used doses; tizanidine decreased the intensity of SR at highest doses tested (0.6 and 1 mg/kg). Dantrolene (20-100 mg/kg), a peripherally acting muscle relaxant, did not affect SR. Effects of serotonergic agents depended on the specific mechanism of action. SR appears to be available for rapid evaluation of the effect of antispasticity drugs.

The effects of alpha-adrenoceptors agents on seizures induced by intraperitoneal administration of lidocaine (75 mg/kg) were studied in mice. Pretreatment with the selective alpha 2-adrenoceptor agonist, tizanidine, decreased the incidence of seizures induced by lidocaine. Tizanidine increased the latency to the first seizure in those animals which progressed to seizures. The blockade of alpha 2-adrenoceptors with yohimbine or phentolamine counteracted the protection induced by tizanidine. The selective alpha 2-adrenoceptor antagonist, prazosin, did not modify the protection induced by tizanidine. The alpha 2-adrenoceptor agonist clonidine also increased the latency to the first seizure induced by lidocaine. The protective effect of clonidine was also reversed by pretreatment with the selective alpha 2-adrenoceptor antagonist yohimbine. Taken together, these results suggest that alpha 2-adrenoceptors are involved in seizures induced by lidocaine.

The effects of tizanidine on the electromyographic responses of forearm flexors and extensors to torque disturbances were studied in normal subjects. Tizanidine had a strong depressive action on all the reflex responses, and on muscle background activity. It is concluded that the action on reflexes is not specific, but secondary to decreased spinal cord excitability.

A method was developed for rapid toxicological analysis of eperisone, tolperisone, and tizanidine in human serum using a MonoSpin® C18 extraction column and LC/MS/MS. The method was validated for LOD, linearity, precision, and extraction recovery. This method was rapid with an LOD of 0.5 ng/mL, linearity range 1-500.0 ng/mL (r2 = 0.999), and RSD value below 14.6%. Extraction recovery from the sample was greater than 98.6, 98.8, and 88.5% for eperisone, tolperisone, and tizanidine, respectively. Results showed that combination of the MonoSpin C18 extraction column and LC/MS/MS is a simple and rapid method for the analysis of these three analytes, and a method is described for simultaneous quantitative determination of the analytes in human serum by LC/MSIMS. This method was used to determine the serum buy zanaflex online levels of eperisone in a patient with eperisone poisoning, and could be successfully applied for screening analyses in clinical cases other than poisoning.

A multi-centre, double-blind study was carried out in 100 patients suffering from chronic spasticity due to multiple sclerosis to compare the effectiveness of tizanidine hydrochloride with that of baclofen. Patients were allocated at random to receive treatment initially with daily doses of either 6 mg tizanidine or 15 mg baclofen and the dose was increased during the first 2 weeks up to a maximum of 24 mg tizanidine or 60 mg baclofen per day. Patients were then treated with the optimum dose for 6 weeks. Efficacy and tolerability parameters were evaluated after 2 and 8 weeks. Tizanidine and baclofen improved the functional status of patients in 80% and 76% of cases, respectively, but there were no significant differences between the two drugs. The antispastic efficacy of tizanidine was greater after 8 weeks than after 2 weeks, whereas the efficacy of baclofen decreased slightly with time. Both drugs showed good overall buy zanaflex online tolerability in more than 60% of patients. Thus, tizanidine is a well tolerated and effective muscle relaxant, the antispastic efficacy of which is well maintained over time, and it promises to be particularly useful in the treatment of spasticity due to multiple sclerosis.

The spectroscopic techniques and semi-empirical molecular calculations have been utilized to analyze the drug Tizanidine (5CDIBTA). The solid phase Fourier Transform Infrared (FTIR) and Fourier Transform Raman (FTR) spectral analysis of 5CDIBTA is carried out along with density functional theory (DFT) calculations (B3LYP) with the 6-311++G(d,p) basis set. Detailed interpretation of the vibrational spectra of the compound has been made on the basis of the calculated potential energy distribution (PED). The individual atomic charges by NPA using B3LYP method is studied. A study on the Mulliken atomic charges, frontier molecular orbitals (HOMO-LUMO), molecular electrostatic potential (MEP) and thermodynamic properties were performed. The electric dipole moment (μ) and the first hyperpolarizability buy zanaflex online (α) values of the investigated molecule were also computed.

Chronic daily headache (CDH), a heterogeneous group of headache disorders occurring on at least 15 days per month, affects up to 4% to 5% of the general population. CDH disorders include transformed (or chronic) migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua. Patients with CDH have greater disability and lower quality of life than episodic migraine patients and often overuse headache pain medications. To date, only topiramate, gabapentin, tizanidine, fluoxetine, amitriptyline, and botulinum toxin type A (BoNTA) have been evaluated as prophylactic treatment of CDH in randomized, double-blind, placebo-controlled, or active comparator-controlled trials. The evidence supporting the use of BoNTA as prophylaxis of CDH buy zanaflex online is composed of larger and longer trials, as over 1000 patients were evaluated for up to 11 months duration. Compared with placebo BoNTA has significantly reduced the frequency of headache episodes, a recommended efficacy measure for headache trials and has been demonstrated to be safe and very well tolerated with few discontinuations due to adverse events. Side effects are generally transient, mild to moderate, and nonsystemic. The results of clinical trials using traditional oral pharmacotherapy, while supportive of their use as prophylactic treatment of CDH, are limited by several factors, including small numbers of patients, the choice of efficacy measures, and short treatment periods. The use of oral agents was associated with systemic side effects, which may limit their effectiveness as prophylactic treatment of CDH.

The electrochemical behaviour of tizanidine [5-chloro(delta-2-imidazolinyl-2-amino)-4-benzothiadiazole-2,1,3], a centrally-active skeletal muscle relaxant has been investigated in aqueous media at the carbon paste electrode (CPE). Cyclic voltammetry Prograf 6 Mg at different pH values, controlled potential coulometry and comparative studies on three structurally related molecules have permitted identification of the oxidation site of tizanidine and suggest possible oxidation products in acidic media. The electrochemical reduction at the CPE occurred in one irreversible step and the reduction product (diamine derivative) was detected and characterized on the positive going scan in cyclic voltammetry. Quantitative measurements of tizanidine within the range 2 x 10(-5) M and 1 x 10(-4) M have been realized at the CPE using the differential pulse technique.

Bolus kinetics after i.t. injection of TZD are best described by a two-phase model. Elimination half-lives of TZD in CSF were 15 min and 152 min, respectively. Clearance of TZD from lumbar CSF was 0.48 ml/min. Doses higher than 500 microgram i.t. caused dose-dependent motor inactivity and sleepiness. Continuous i.t. Zanaflex Cost TZD up to 4 micrograms/d was well tolerated regarding behavioral, physical activity, heart rate, muscle counts and total protein were detected both in saline and TZD-treated animals, presumably due to local irritation by the catheter and repeated sampling procedures. Histological evaluation of the spinal cord and adjacent tissues showed no abnormalities.

Tizanidine hydrochloride is an orally administered prokinetic agent that facilitates or restores motility through-out the length of the gastrointestinal tract. The objective of the present investigation was to develop effervescent floating matrix tablets of tizanidine hydrochloride for prolongation of gastric residence time in order to overcome its low bioavailability (34-40 %) and short biological half life (4.2 h). Tablets were prepared by the direct compression method, using different viscosity grades of hydroxypropyl methylcellulose (HPMC K4M, K15M and K100M). Tablets were evaluated for various physical parameters and Deltasone Dose Pack floating properties. Further, tablets were studied for in vitro drug release characteristics in 12 hours. Drug release from effervescent floating matrix tablets was sustained over 12 h with buoyant properties. DSC study revealed that there is no drug excipient interaction. Based on the release kinetics, all formulations best fitted the Higuchi, first-order model and non-Fickian as the mechanism of drug release. Optimized formulation (F9) was selected based on the similarity factor (f2) (74.2), dissolution efficiency at 2, 6 and 8 h, and t50 (5.4 h) and was used in radiographic studies by incorporating BaSO4. In vivo X-ray studies in human volunteers showed that the mean gastric residence time was 6.2 ± 0.2 h.

The drug-drug interactions of tizanidine and cytochrome (CYP) P450 1A2 inhibitors, which potentially alter the hepatic metabolism of tizanidine, were investigated by retrospective survey of medical records with regard to prescription. One thousand five hundred sixty-three patients treated with tizanidine at University of Tsukuba Hospital were investigated. Of those, 713 patients (45.6%) were treated with coadministration of tizanidine and CYP1A2 inhibitors (37 drugs). The patients who received a combination of tizanidine and CYP1A2 inhibitors were characterized as elderly, having multiple diseases, and taking a large number of comedications (over 10 drugs) for a long period as compared with Lamictal Bipolar Medicine the patients who did not receive CYP1A2 inhibitors. Tizanidine-induced adverse effects were examined in 100 patients treated with coadministration of tizanidine and 8 CYP1A2 inhibitors. Adverse effects (e.g., drowsiness: 10 patients; low blood pressure: 9 patients; low heart rate: 9 patients) were observed in 23 patients (23%) 8±10 days after CYP1A2 inhibitors were coadministered. The patients with tizanidine-induced adverse effects were of older age (64.3±9.8 vs. 57.5±18.1 years, p<0.05) and received a higher daily dose of tizanidine (3.00±0.74 vs. 2.56±0.86 mg/day, p<0.05) than the patients without adverse effects. The present results suggest that coadministration of tizanidine and CYP1A2 inhibitors enhances tizanidine-induced adverse effects, especially in elderly patients treated with a higher dose of tizanidine.

We investigated the involvement of the spinal cord melanocortin (MC) system in neuropathic pain. Because we recently demonstrated that MC receptor ligands acutely alter nociception in an animal model of neuropathic pain, in this study we tested whether chronic administration was also effective. We hypothesized that chronic blockade of the spinal MC system might decrease sensory abnormalities Micardis Y Alcohol associated with this condition. The effects of the MC receptor antagonist SHU9119 (0.5 microg/d) and agonist MTII (0.1 microg/d) were evaluated in rats with a chronic constriction injury of the sciatic nerve. Drugs were continuously infused into the cisterna magna. Antinociceptive effects were measured with tests involving temperature (10 degrees C or 47.5 degrees C) or mechanical (von Frey) stimulation. The administration of MTII increased mechanical allodynia, whereas SHU9119 produced a profound cold and mechanical antiallodynia, altering responses to control levels. The antiallodynic effects of SHU9119 were very similar to those produced by the alpha(2)-adrenergic agonist tizanidine (50 microg/d). The effects of SHU9119 and MTII are most likely mediated through the MC4 receptor, because this is the only MC-receptor subtype present in the spinal cord. We conclude that the chronic administration of MC4-receptor antagonists might provide a promising tool in the treatment of neuropathic pain.
