Tương tác
Concomitant use with methocarbamol may result in accommodation disorder of the eyes. Increased sedative effect with other centrally-acting muscle relaxants. May increase the blood levels of drugs that are metabolised by CYP2D6 (e.g. thioridazine, tolterodine, venlafaxine, atomoxetine, desipramine, dextromethorphan, metoprolol, nebivolol, perphenazine). Potentiates the effect of niflumic acid or other NSAIDs.

Tác dụng
Description:
Mechanism of Action: Tolperisone is a centrally acting muscle relaxant that inhibits mono- and polysynaptic reflex transmission by both pre-synaptic and post-synaptic mechanisms. It stabilises neuronal membranes by decreasing the influx of Na and the amplitude and frequency of action potentials, it inhibits voltage-dependent Ca channels thus reducing transmitter release, and decreases the reticulo-spinal facilitation in the brainstem. Pharmacokinetics: Absorption: Rapidly absorbed. Bioavailability: 17%; increased with a high-fat meal. Time to peak plasma concentration: 30-60 minutes. Distribution: Volume of distribution: 5 L/kg. Metabolism: Metabolised in the liver mainly by the CYP2D6 and to a lesser extent CYP2C19, CYP2B6, and CYP1A2 isoenzymes to 11 metabolites. Excretion: Via urine (98%, as unchanged drug and metabolites). Elimination half-life: 1.5-2.5 hours. |
