[Therapeutic effect of dexalgin on disturbances of vertebrogenic and nonvertebrogenic mechanisms in back pain].
To evaluate the effect of Dexalgin on dysregulation mechanisms in the complex therapy of dorsalgia, 39 patients have been studied. They were divided into 2 groups: with vertebrogenic (23 patients) and without vertebrogenic (16 patients) pain syndrome. Dexalgin was prescribed in dosage 75 mg daily during 5 days. Its efficacy was measured using the Visual Analogue Scale (VAS), Mc Gill Pain Questionnaire, OBPDQ in case of low back pain. Electromyographic (EMG) and magnetic resonance imaging (MRI) examination was performed in radiculopathic patients receiving dexalgin. The results revealed a statistically significant decrease of the VAS values at the control examination in both groups of patients (p<0,001) with background RI values being 18,4 +/- 9,7 and 21,2 +/- 11,7, respectively. The considerable reduction of RI to 14,6 +/- 9,2 was observed in the second group (p=0,044) on day 5. Dynamic examination showed the predominant decrease of OBPDQ percentage values in patients with myofascial back pain (p=0,038). The EMG data demonstrated a tendency to reduction of spontaneous activity in muscular fibers and normalization of the H-reflex latency during the tibial nerve conduction study in patients with vertebrogenic dorsalgia (p=0,058 and p=0,064, respectively). Dexalgin is the new generation of nonsteroid analgesics possessing potential in treatment of both, acute and exacerbations of chronic dorsalgias. No significant between-group differences were found in the MRI study. The study revealed dexalgin efficacy in patients with myofascial low back syndrome.
