Tolperisone hydrochloride is a centrally acting muscle relaxant. It has a membrane-stabilizing, local anesthetic effect, inhibits the conduction of nerve impulses in the primary afferent fibers and motor neurons, which leads to blocking of spinal mono- and polysynaptic reflexes. Probably, it mediates the blocking of the release of mediators by inhibiting the entry of calcium ions into synapses. It inhibits the conduction of excitation along the reticulospinal pathway in the brain stem. Regardless of the effect on the central nervous system, it enhances peripheral blood flow. The weak antispasmodic and antiadrenergic effect of tolperisone may play a role in the development of this effect.
