Drug Class and Mechanism
Tizanidine reduces spasticity by increasing presynaptic inhibition of motor neurons. It is an agonist at (alpha) 2 -adrenergic receptor sites. Tizanidine has no direct effect on skeletal muscle fibers or the neuromuscular junction, and no major effect on monosynaptic spinal reflexes in animal models. Its effects are most remarkable on polysynaptic pathways. The net result of all these action is believed to reduce facilitation of spinal motor neurons.
Tizanidine’s imidazoline chemical structure is similar to other (alpha) 2 -adrenergic agonists and anti-hypertensive drug clonidine. Research and pharmacological studies conducted on animals show similarities between the two but Tizanidine shows a potency of one-tenth to one-fiftieth (1/50) of that of clonidine in lowering blood pressure.
Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
Store Zanaflex at room temperature (read medicine label if unsure). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets. It should be properly disposed when expired or not needed.
Your condition might be monitored or the dosage might be modified to suit you if you have conditions like iver disease, have kidney disease, have low blood pressure or you are on medication to treat high blood pressure; or you are taking birth control pills
Zanaflex may increase the risk of getting dizziness or drowsiness. This risk greatly increases if you combine it with alcoholic beverages. So please avoid them while using Zanaflex. Also, avoid undertaking any tasks which require mental alertness (driving, handling heavy machinery etc).
