title: [Comparative evaluation of the protective action of nalorphine and pentazocine in acute morphine and promedol poisoning].
abstract: It was shown in experiments on white rats that the intensity of the antitoxic action of nalorphine (0.57 mg/kg) and pentazocin (3 mg/kg) is related to the chemical structure of a narcotic analgetic agent. This action is more clearly manifested during poisoning induced by the phenylpiperidine derivative promedol (LD50 33.33 mg/kg). Nalorphine increases LD50 of promedol and corrects of metabolic disturbances produced by promedol. Pentazocin does not compare favourably to nalorphine since it mostly acts as a stimulant of external respiration.
