title: Pharmacology of Bay g 2821, a long-acting, high-ceiling diuretic.
abstract: Bay g 2821 is a diuretic, from a new class of chemical substances, with both the efficacy of diuretics with a high-ceiling activity, such as furosemide, bumetanide and ethacrynic acid, and the prolonged duration of action of thiazides. Pharmacological investigations showed that Bay g 2821 was more potent than furosemide in dogs but less potent in rats. Bay g 2821 did not differ from furosemide in excretion of electrolytes. Further studies showed that Bay g 2821 had an antihypertensive effect in dogs, spontaneously hpertensive rats, and in rats with artificially-induced renal hypertension. Other pharmacological studies did not reveal any other significant effects.
