Use

In vitro studies of human liver microsomal cytochrome P450 isozymes showed that Tizanidine and its metabolites do not affect the metabolism of other enzymes. Tizanidine makes the peak time of acetaminophen delayed by 16 minutes, but paracetamol does not affect the pharmacokinetic parameters of Tizanidine. Ethanol increases the area under the curve of Tizanidine by 20%, resulting in an increase of 15% in the maximum peak concentration and an increased side effect in Tizanidine.The central nervous system inhibition of ethanol and Tizanidine has additive effect. 4mg Tizanidines single or repeated retrospective study showed that the use of oral contraceptives compared with patients who did not take oral contraceptives at the same time reduced the scavenging rate of Tizanidine Hydrochloride by 50%. When combined with antihypertensive drugs and diuretics, hypotension and bradycardia can be induced. It is prohibited to use combined with fluoxamine or ciprofloxacin(Cytochrome oxidase CYP1A2 inhibitor). Clinical studies showed that the pharmacokinetic parameters of Tizanidine (area under the curve, elimination half-life, maximum blood concentration, and oral bioavailability) will be increased when combined with fluoxamine and ciprofloxacin simultaneously, while the plasma clearance rate will be decreased. This pharmacokinetic interaction may lead to serious adverse events.
