Pharmacological properties
Midocalm is a medication that reduces muscle tone (muscle relaxant) with a central action. It has a high affinity (degree of specific affinity) for the nervous tissue. The highest concentrations are reached in the spinal cord, brain stem, and peripheral nervous system (nerves and nerve endings). The most significant drug effect is its inhibitory effect on the reflex pathway of the spinal cord. This effect, combined with a depressing effect on the descending pathways, determines the effect of the drug.
The chemical structure of the active drug molecule is similar to that of lidocaine. Like the anesthetic lidocaine, it has a membrane-stabilizing effect, reduces the electrical excitability of motor neurons, primary afferent fibers. The drug inhibits the activity of voltage-gated Na-channels (dose-dependent). At the same time, the amplitude, the frequency of the action potential, decreases. The inhibitory effect on voltage-gated Ca-channels has also been proven. This indicates that the drug has not only a membrane-stabilizing effect, but is also capable of suppressing the release of transmitters (transmitter substances). In addition, the drug has weak properties of alpha-adrenergic receptor antagonists, has an antimuscarinic effect.

Tablets Midocalm are indicated for the symptomatic treatment of muscle spasm in adults (for example, after a stroke).

You can not prescribe Midocalm if you are allergic to the active substance (tolperisone) or similar in chemical composition to eperisone, excipients, for the solution – allergies to amide local anesthetics. Do not prescribe this medicine for Myasthenia gravis. Do not use the solution in children.

Application during pregnancy and lactation
Use during pregnancy is contraindicated. Due to the lack of significant clinical data, the appointment of Midocalm in the II-III trimesters is possible when the expected benefit to the mother, in the opinion of the doctor, outweighs the risk to the child.
Since the ability to penetrate active molecules (tolperisone) into breast milk is unknown, use during breastfeeding is contraindicated.

Method of administration and dosage
The duration of treatment is determined by the doctor, depending on the course of the disease, the effectiveness of treatment.
The tablets should be taken after meals with water. Insufficient food intake can reduce the bioavailability of the drug. The dose is selected by the doctor depending on the individual need, tolerance. Usually 150-450 mg / day in 3 divided doses.

Data on overdose have been reported. The literature describes the oral administration of a dose of 600 mg in childhood without the manifestation of severe toxic symptoms. After oral administration of 300–600 mg of the drug per day in pediatric patients, irritability was observed in some cases. In experiments conducted on animals aimed at determining the toxicity of the drug, large doses caused impaired coordination of movements (ataxia), clonic and tonic convulsions, respiratory disorders, and paralysis of the respiratory muscles.
There is no specific antidote. In case of an overdose, it is recommended to carry out immediate gastric lavage, prescribe symptomatic, supportive treatment.
