Indian Journal of Physiology and Pharmacology. 1977 Jul-Sep; 21(3): 195-8http://imsear.searo.who.int/handle/123456789/107097Intravenously administered oxytocin caused a dose-related fall in blood pressure of the rabbit. When oxytocin was administered in oestrogen-primed animals, the depressor response was converted to a pressor one "Oxytocin reversal". The "oxytocin reversal." was abolished after treatment with dihydroergotamine, hexamethonium or adrenalectomy. The "oxytocin reversal" did not appear in reserpinized animals.engAdrenalectomyAnimalsBlood Pressure --drug effectsDihydroergotamine --pharmacologyEstriol --analogs & derivativesEstrogens --pharmacologyFemaleHexamethonium Compounds --pharmacologyMaleOxytocin --pharmacologyPancuronium --analogs & derivativesRabbitsReserpine --pharmacologyStimulation, ChemicalJournal Article
