Symptomatic treatment of neurolathyrism with tolperisone HCL (Mydocalm): a randomized double blind and placebo controlled drug trial.
The efficacy and safety of oral Tolperisone HCL was evaluated in double blind, placebo-controlled, randomized trial in 72 patients with neurolathyrism in stages I, II, and III of the disease at Kolla Duba Health Centre of Dembia District of North Gondar between January and April 1995. Taken orally daily for 12 weeks, tolperisone HCL (Mydocalm) in a dose of 150 milligrams (mgs) twice daily significantly improved subjective complaints such as muscle cramps, heaviness of the legs, startle attacks, flexor spasms and repeated falls. An overall subjective improvement was observed in 75% of the patients on tolperisone HCL and 39% of the placebo group (P = 0.002). When objectively assessed spastic muscle tone in the abductors, stiffness of Achilles and spontaneous ankle clonus were significantly reduced in tolperisone HCL group (P values = 0.001, 0.04, and 0.0001, respectively). Walking ability and speed of walking was also significantly improved. The drug is most effective in relieving symptoms of stage I and stage II disease. Some adverse effects like muscle pain, generalized body weakness and dizziness were recorded in patients taking the drug but all were minor and self limited, none requiring discontinuation of treatment. It is concluded that tolperisone is a well tolerated and efficacious drug for symptomatic treatment of neurolathyrism.
