[A study of mydocalm efficiency in the treatment of chronic headache of tension].

Mydocalm was used for the treatment of 31 patients, mean age 45 +/- 4 years, with chronic headache of tension in a dosage of 150 mg 3 times per day during 4 weeks. Twenty-six patients have completed the therapy course. Before- and after treatment, neurological status, dynamics of psychoautonomic disorders, an extent of anxiety and depression, quality of sleep, quality of life, pain syndrome measured by a number of tests, were assessed, along with electromyography and examination of nociceptive reflex. Subjective evaluation of the drug efficacy was taken into account as well. A marked positive effect of mydocalm was observed in 70% of patients, moderate effect--in 30%. A predictor of mydocalm efficacy was severity of muscle tonic syndrome.
