Hypotensive effect of retabolil correcting the concentration of aldosterone during stress exposures.

Abstract

Male rats were exposed to single or repeated (19 days) cold treatment (4°C) and non-cold stress (60-min shaking on a laboratory shuttle device). Retabolil had a hypotensive effect, which was accompanied by the prevention of a stress-induced increase in the concentration of a hypertensive hormone aldosterone. Under conditions of repeated stress, these effects were realized via μ-opioid receptors. Our results suggest that retabolil can be used as a hypotensive and aldosterone-blocking agent, at least during stress exposure in animals (and probably in humans).
