UsesTolperisone hydrochloride can be used as a muscle relaxant.
DefinitionChEBI: Tolperisone hydrochloride is an aromatic ketone.
Manufacturing ProcessTo 1-(4-methylphenyl)-3-(1-piperidinyl)-1-propanol in chloroform was added an excess of thionyl chloride and the reaction mixture refluxed until completed. It was then taken to dryness under reduced pressure and the residue crystallized by dissolving in hot alcohol and diluting with ethyl acetate. An aqueous solution of the obtained N-[3-chloro-3-(p-tolyl)propyl]piperidine hydrochloride was hydrogenated at 3 atmospheres in the presence of buffered palladium-on-charcoal catalyst. 1-Piperidino-2-methyl-3-(p-tolyl)-3-propanone was purified by distilling the base (boiling point 106-107°C/1 mm) and reconverting to the hydrochloride, melting point 216-217°C.
Therapeutic FunctionMuscle relaxant, Vasodilator
Biochem/physiol ActionsTolperisone is derived from piperidine and possesses membrane stabilizing action. It helps in reducing the effect of spasticities associated with the nervous and muscular system. It exhibits muscle relaxant action through attenuating voltage-gated sodium channels in the brain stem.
