ABSTRACT
AIM:
The "PARUS" program included investigation of the analgesic, muscle relaxant and sedative effects of Mydocalm-Richter which acts as central muscle relaxant in patients with myofascial pain syndrome, taking into account its registered indication for use - the hypertonus and cross-striated muscle spasm. MATERIALS ANDMETHODS:
Fifty patients with myofascial trigger points, the mean age of 41.67±11.86 years, have been enrolled in the study. All patients had undergone clinical examination that allowed the diagnosis of myofascial pain syndrome. The intensity of pain syndrome was evaluated using the pain visual analogue scales and McGill pain questionnaire. Visualization of area in spasm and evaluation of blood circulation was carried out using the ultrasound scan of target muscle. In order to objectively evaluate any conceivable hypotensive and sedative effects of Mydocalm-Richter we used the orthostatic test, Schulte's test for attention span and perfor-mance distribution and Munsterberg's test for attention discrimination and concentration.RESULTS:
The analgesic and muscle relaxant effects of Mydocalm-Richter become apparent by day 3 post-injection, and the muscle relaxation effect is reaching its maximum on day 10 post-injection. Cardiovascular function following administration of Mydocalm-Richter was evaluated using the orthostatic test which revealed good orthostatic tolerance. Single injection of tolperisone hydrochloride possessing a central muscle relaxant activity has no sedative effect and does not influence patient response time. The ultrasound examination data demonstrated the improvement and in some cases restoration of blood circulation in the myofascial trigger points.CONCLUSION:
Clinical study "PARUS" conducted in patients with myofascial pain has demonstrated a positive muscle relaxant and analgesic effect of Mydocalm-Richter that resulted in restoration of peripheral circulation in the myofascial trigger pointsconfirmed by ultrasound examination. An important benefit of this drug product is the absence of sedative effect and arterial hypotension.Key words
