Monkeys were shown to self-administer tizanidine in a dosage dose-dependent manner, and dosage abrupt cessation of zanaflex dosage zanaflex tizanidine produced transient signs of dosage withdrawal at doses zanaflex 35 times the zanaflex maximum recommended human dose on a zanaflex mg/m zanaflex high zanaflex basis. When two 4 mg dosage tablets were administered with zanaflex food, the mean maximal plasma concentration was dosage dosage increased by zanaflex approximately 30, and the median time to peak plasma concentration was increased by 25 minutes, to 1 hour and 25 minutes. The dosage Cmax, AUC, and half-life of dosage tizanidine increased by 12- fold, 33-fold, and 3-fold, respectively. Tell patients that they should zanaflex not dosage suddenly discontinue Zanaflex, because rebound hypertension and tachycardia may occur. The above information zanaflex is provided for general informational zanaflex and educational purposes only. Zanaflex zanaflex Dosing zanaflex Tell patients to take Zanaflex exactly as prescribed (consistently either zanaflex with or without food) and not to switch between tablets and capsules. Food also zanaflex increased the extent of dosage absorption for both the tablets and capsules.

Most commonly, these are generic drugs. Dosing Information, zanaflex Capsules or Zanaflex tablets may be prescribed with or without food. Reproduction studies performed in rats at a dose of 3 dosage mg/kg, equal to the maximum recommended human dose on a mg/m basis, and in rabbits at 30 mg/kg, 16 times the maximum recommended human dose on a mg/m basis, did not show evidence of teratogenicity. Code Definition PA Prior Authorization Drugs that require prior authorization. See warnings AND precautions and clinical pharmacology Oral Contraceptives Concomitant use zanaflex 4mg zanaflex high dosage of Zanaflex with oral contraceptives is not recommended. Geriatric use Zanaflex is known to be substantially excreted dosage by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Respiratory depression is another common feature of tizanidine overdose. Tizanidine is a short-acting muscle relaxer that's marketed under the brand name Zanaflex.

If therapy needs to be discontinued, the dose should be decreased slowly to minimize the risk of withdrawal symptoms see dosage AND administration. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. The following adverse reactions have been identified as occurring in the post dosage marketing experience of Zanaflex. During titration, the individual doses should be reduced. Animal studies have shown an adverse effect, but there are no adequate studies in pregnant women. Acetaminophen Tizanidine delayed the Tmax of acetaminophen by 16 minutes. If adverse reactions such as hypotension, bradycardia, or excessive drowsiness occur, reduce zanaflex or discontinue Zanaflex therapy. Hepatic impairment, zanaflex close monitoring of ADRs (eg, hypotension avoid dosage in severe impairment.

The occurrence of these reactions is summarized in Table. Administration of the capsule contents on applesauce resulted in a 1520 increase zanaflex in Cmax and AUC of tizanidine and a 15 minute decrease in the median lag time and time to peak concentration compared to administration of an intact capsule while fasting. These changes may result in increased adverse events, or delayed or more rapid onset of activity, depending upon the nature of the switch. Alcohol Alcohol increased the AUC of tizanidine by approximately 20, while also increasing its Cmax by approximately. Tizanidine at doses that are equal to and up to 8 times the maximum recommended human dose on a mg/m basis increased gestation duration in rats. Three double-blind, randomized, placebo controlled -clinical studies were conducted to evaluate the effect of tizanidine on spasticity control. Therefore, dialysis is not likely to be an efficient method of removing drug from the body.

One patient among zanaflex these 5 continued to have problems for at least 2 weeks following discontinuation of tizanidine.

Warnings Precautions warnings Included as part of the precautions section. Cross study comparison of pharmacokinetic data following single dose administration of 6 mg Zanaflex showed that younger subjects cleared the drug four times faster than the elderly subjects. The overall effect of these actions is thought to reduce facilitation of spinal motor neurons. Rats zanaflex were able to distinguish tizanidine from saline in a standard discrimination paradigm, after training, but failed to generalize the effects of morphine, cocaine, diazepam, or phenobarbital to tizanidine. See dosage AND administration, warnings AND precautions and clinical pharmacology Impaired Hepatic Function The influence of hepatic impairment on the pharmacokinetics of tizanidine has not been evaluated. Compare formulary status to other drugs in the same class. Although 16 mg produced a larger effect, adverse events including hypotension were more common and more severe than in the 8 mg group.
