Prostaglandin F2 alpha and cardiovascular system: review of studies conducted in dogs.

The study was designed to investigate the effect of PGF2 alpha on the arterial, cardiac and venous system and the respiration of dogs. PGF2 alpha was administered in single, graded doses as well as by i.v. perfusion. In addition, PGF2 alpha was given intra-arterially into the common carotid artery, by inhalation and by infiltration into the barosensitive zone of the carotid sinus. The interaction by drugs acting on ganglia, the catecholamine stores and the muscarinic, histaminergic, serotonergic, adrenergic and purinergic junctions, and by drugs with depressive effects at the prostaglandin receptors, also were studied. We have shown that PGF2 alpha exhibits direct, reflexes and modulator effects.
