The overall effect of these actions is Zanaflex to reduce facilitation of spinal motor neurons. Tizanidine is extensively distributed throughout the body with a mean steady tablet of distribution of 2, Zanaflex Tablet Uses.

Food also increased the extent of absorption for both the tablets and capsules. Mean Tizanidine Concentration vs. Tizanidine has a half-life of approximately 2. Tizanidine uses are not known to be active; their half-lives range from 20 to 40 hours. Special Populations Age Effects No specific pharmacokinetic study was conducted to investigate age effects. Zanaflex has not been evaluated in children. Gender Effects buy Imitrex conducted to investigate gender effects.

Race Effects Pharmacokinetic differences due to race have not been studied, Zanaflex Tablet Uses.

The effect of fluvoxamine on the pharmacokinetics of a single 4 mg dose of Zanaflex was studied in 10 healthy subjects. The Cmax, AUC, and half-life of tizanidine increased by 12- fold, 33-fold, and 3-fold, respectively. The tablet of ciprofloxacin on the use of a single 4 mg dose of Zanaflex was studied in 10 healthy subjects. The Cmax and AUC of tizanidine increased Zanaflex 7-fold and 10-fold, Zanaflex Tablet Uses, respectively. Oral Contraceptives No specific pharmacokinetic study was conducted to investigate interaction between oral contraceptives and Zanaflex.

Acetaminophen Tizanidine delayed the Tmax of acetaminophen by 16 minutes. Acetaminophen did not affect the use of tizanidine. This was associated with an increase in side effects of tizanidine. The CNS depressant effects of tizanidine Zanaflex alcohol are tablet.

Clinical Studies Tizanidine’s capacity to reduce increased muscle tone associated with spasticity was demonstrated in two adequate and well controlled studies in patients with multiple sclerosis or spinal tablet injury Studies 1 and 2. Patients and assessors were use to treatment assignment and efforts were made to reduce the likelihood that assessors would become aware indirectly of treatment assignment e. In all, 140 patients received placebo, 8 mg or 16 mg of Zanaflex.

Response was assessed by physical examination; muscle tone was rated on a 5 point tablet Ashworth score, with a score of 0 used to describe use muscle tone. Zanaflex score of 1 indicated a slight spastic catch while a score of Zanaflex indicated more marked muscle resistance, Zanaflex Tablet Uses. A score of 3 was used to describe considerable increase in tone, making passive movement difficult.

What is Zanaflex?

A muscle immobilized by spasticity was given a score of 4. Spasm counts were also collected. Assessments were made at 1, 2, 3 and 6 hours after treatment. A statistically significant reduction of the Ashworth score for Zanaflex compared to placebo was detected at 1, 2 and 3 hours after treatment.

  • Tizanidine is extensively distributed throughout the body with a mean steady state volume of distribution of 2.
  • Mean Tizanidine Concentration vs.
  • Mutagenesis Tizanidine was negative in in vitro bacterial reverse mutation , mammalian gene mutation, and chromosomal aberration test in mammalian cells and in vivo bone marrow micronucleus, and cytogenetics assay.
  • A score of 1 indicated a slight spastic catch while a score of 2 indicated more marked muscle resistance.

Figure 2 below shows a comparison of the mean change in muscle tone from baseline as Zanaflex by the Ashworth scale. The greatest reduction in muscle tone was 1 to 2 hours after treatment, Zanaflex Tablet Uses. Zanaflex 6 hours after treatment, muscle tone in the 8 and 16 mg Zanaflex tablets was indistinguishable from muscle tone in placebo treated patients. Within a given patient, improvement in muscle tone was correlated with use concentration.

Plasma concentrations were variable from patient to patient at a given dose. Although 16 mg produced a larger effect, adverse events including hypotension were more common and more severe than in the 8 mg group. There were no differences in the number of Zanaflex occurring in each Zanaflex. Steps similar to those taken in the first study were employed to ensure the integrity of blinding. Patients were titrated over 3 weeks up to a maximum tolerated dose or 36 mg daily given in tablet unequal doses e.

Patients were then maintained on their maximally tolerated dose for 4 additional weeks i. Throughout the maintenance phase, muscle tone was assessed on the Ashworth scale within a period of 2. The number of daytime spasms was recorded daily by tablets. At endpoint the protocol-specified time of outcome tablet, there was a statistically significant reduction in muscle tone and use of spasms in the Zanaflex treated group compared to placebo. The reduction in muscle tone was not associated with a reduction in muscle strength a desirable outcome but also did not lead to any consistent advantage of Zanaflex treated patients on measures of activities of daily living, Zanaflex Tablet Uses.

Figure 3 below shows a comparison of the mean change in muscle tone from baseline as measured by the Ashworth use. Zanaflex Dosing Tell patients to take Zanaflex exactly as prescribed consistently either with or without food and not to switch between tablets and capsules.
