[Evaluation of the pain-alleviating properties of a combination of analgesic and tranquilizer using multiple stepwise regression].

A method for preclinical evaluation of the optimal ratio (for analgesia) of an analgesic to a tranquilizer has been devised. It is based on the drug threshold dose decrease on the drug combined use. The multiple stepwise regression analysis of the data discovered the correlations between diazepam and promedol, optimal for pain perception decrease and nociceptive emotional responsiveness inhibition.
