The authors carried out a study on beta-adrenergic blockers Proprafnolol, Pindolol and Practolol, on an isolated uterus of a rat, obtained at various phases oestrus. The Beta-adrenergic blocker Pindolol manifested inhibiting effect on the spontaneous contractility of the uterus more marked after elevated level of gestagens. The pharmacological analysis gave foundation to the authors to assume that the relaxation of Pindolol was due to direct myotropic action. Propranolol in large doses and at high gestagenic level manifested antioxytocic activity. Practolol did not affect both spontaneous uterine activity as oxytoxin contraction.
