Egualen sodium (sodium 3-ethyl-7-isopropyl-1-azulenesulfonate 1/3 hydrate) is a new antiulcer drug. There has been no difference observed in absorption between male and female rats, the relative amount of metabolites in male plasma has been higher than that in females, and the excretion ratios of metabolites in males have been significantly higher than(More)
Three hydroxylated metabolites of 2-propyl-3-[2'-(1H-tetrazol-5-yl)biphenyl-4-ylmethyl]-5,6,7,8-tetrahydro-3H-cycloheptimidazol-4-one (Pratosartan), which is a selective angiotensin II receptor antagonist, were synthesized in confirmation of their structures and in studies of their pharmacological properties. An MTPA ester of the human main metabolite was(More)
The antihypertensive activity and pharmacokinetics of KD3-671 (previously named KT3-671), a nonpeptide AT1-receptor antagonist, were investigated in renal hypertensive dogs with normal or high plasma renin activity (PRA). A single administration of KD3-671 at 3 and 10 mg/kg, p.o., to the hypertensive dogs with high PRA dose-dependently reduced mean blood(More)
Angiotensin converting enzyme (ACE) inhibitor prevents the inactivation of bradykinin by inhibiting ACE activity, leading to side effects such as dry cough and angioedema. KD3-671 is a novel nonpeptide angiotensin II antagonist which is expected to exhibit persistent hypotensive action without these side effects. In this study, we investigated the(More)
