Drug Interactions CYP1A2 Inhibitors The interaction between Zanaflex zanaflex and zanaflex high dosage either fluvoxamine or ciprofloxacin is dosage most likely due to zanaflex inhibition of zanaflex CYP1A2 by zanaflex 4mg zanaflex fluvoxamine or ciprofloxacin. It's used to dosage treat zanaflex muscle spasms caused by certain conditions such as multiple sclerosis, ALS, or spinal cord injury. Prenatal and dosage postnatal pup loss was increased and zanaflex developmental retardation occurred. The occurrence of these reactions is zanaflex summarized in zanaflex Table. Be sure to be dosage consistent and either take only with dosage food or only take without food. Potential Interaction with dosage Other CYP1A2 Inhibitors. In all, 140 patients received placebo, 8 mg zanaflex or 16 mg of Zanaflex. Instruct patients to inform their physicians or pharmacists when they start or stop taking any medication dosage because of the risks associated with zanaflex interaction between Zanaflex and other medicines. Clinical Pharmacology clinical pharmacology Mechanism of action Tizanidine dosage is a central alpha-2-adrenergic receptor agonist and presumably reduces spasticity by increasing presynaptic inhibition of motor zanaflex neurons. For comparison purposes, the corresponding frequency of the event (per 100 patients) among placebo treated patients is also provided. In the majority of cases a decrease in sensorium was observed including lethargy, somnolence, confusion and coma. These events appeared to be dose zanaflex related. The effects of tizanidine are greatest on polysynaptic pathways. Zanaflex should dosage be given zanaflex to pregnant women only if the benefit zanaflex zanaflex outweighs the risk to the unborn fetus. The effect of fluvoxamine on the pharmacokinetics of a single 4 mg dose of Zanaflex was studied in 10 healthy subjects. Tizanidine is slightly soluble in water and methanol. Administration of the capsule contents on applesauce resulted in a 1520 increase in Cmax and AUC of tizanidine and a 15 minute decrease in the median lag time and time to peak concentration zanaflex compared to administration of an intact capsule while fasting.

The Cmax and AUC of tizanidine increased by 7-fold and 10-fold, respectively. Acetaminophen Tizanidine delayed the Tmax of acetaminophen by 16 minutes. In vitro studies of cytochrome P450 isoenzymes using human liver microsomes indicate that neither tizanidine nor the major metabolites are likely to affect the metabolism of other drugs zanaflex side effects metabolized by cytochrome P450 isoenzymes. Certain events, such as somnolence, dry mouth, hypotension, decreased blood pressure, bradycardia, dizziness, weakness or asthenia, muscle spasms, hallucinations, fatigue, liver function test abnormality and hepatotoxicity, have been observed in post marketing and clinical trials and are discussed in previous sections of this document.
