Pharmacological properties

Tolperisone is a centrally acting muscle relaxant. The mechanism of action of tolperisone is not fully understood.
It has a high affinity for nervous tissue, reaching the highest concentrations in the brain stem, spinal cord and peripheral nervous system.
The most significant effect of tolperisone is its inhibitory effect on the spinal reflex pathway. Probably, this effect together with the inhibitory effect on the descending conduction pathways determines the therapeutic benefit of tolperisone.
The chemical structure of tolperisone is similar to the structure of lidocaine. Like lidocaine, it has a membrane-stabilizing effect and reduces the electrical excitability of motor neurons and primary afferent fibers. Tolperisone dose-dependently inhibits the activity of potential-dependent sodium channels. Accordingly, the amplitude and frequency of the action potential decreases.
The inhibitory effect on potential-dependent calcium channels has been proven. It is assumed that in addition to its membrane-stabilizing action, tolperisone may also inhibit the release of the mediator.
To top it all off, tolperisone has some weakly pronounced properties of α-adrenergic antagonists and has an antimuscarinic effect.

Indication

Symptomatic treatment of muscle spasm in adults after stroke.

Contraindication

• Hypersensitivity to the active substance or to chemically similar eperisone, or to any of the excipients.
• Myasthenia gravis.
• Breastfeeding period.

Method of application and dosage

The drug Tolperil coated tablets should be taken after a meal, washed down with a glass of water. Insufficient food intake may reduce the bioavailability of tolperisone.
Adults, depending on individual needs and tolerability – 150-450 mg / day for 3 doses.
The duration of treatment is determined individually.
Patients with impaired renal / hepatic function. Experience with tolperisone in patients with renal / hepatic impairment is limited, with a higher incidence of adverse events in such patients. Therefore, in moderate renal / hepatic impairment, individual dose titration with careful monitoring of the patient and monitoring of renal / hepatic function is recommended. Tolperisone is not recommended for severe renal / hepatic impairment.

Children

The safety and efficacy of tolperisone in children have not been studied.

Overdose

Data on overdose are limited. Symptoms of overdose may mainly include drowsiness, gastrointestinal manifestations (nausea, vomiting, epigastric pain), tachycardia, hypertension, bradykinesia, and vertigo. In severe cases, there were reports of seizures and coma.
Treatment: symptomatic and supportive therapy. There is no specific antidote.
