title: [Influence of captopril on the in vitro and in vivo effects of leu- and met-enkephalins].
abstract: Captopril (10(-6) g/ml) enhanced and prolonged the inhibitory effect of leu- and met-enkephalins on the contractions of the isolated guinea-pig ileum section induced by electrical stimulation. In mice, the drug (25 mg/kg, subcutaneously) increased the degree and duration of the analgetic effect of enkephalins. It is concluded that the analgetic effect of captopril is related to the influence on the activity of the endogenous antinociceptive system.
