[A comparison of the effect of tranquilizers in experiments and clinical practice].

Experimental and clinical study of the analgesic effects of mebicar and benzodiazepine series tranquilizers (sibazon and chlozepid) and their combinations with non-narcotic analgesics (amidopyrin, pyranal) or local anesthetic lidocaine has demonstrated a more marked effect of benzodiazepine derivatives on pain sensitivity thresholds as against mebicar. Tranquilizer combinations with other analgesics helped define the optimal premedication variants: benzodiazepine derivative augment analgesic activity whereas mebicar potentiates lidocaine effect.
