...Richard W. Chapman; Salvatore Tozzi; William Kreutner HA 1004 is a calcium antagonist vasodilator that inhibits contraction in vascular smooth muscle and lowers arterial blood pressure. The effects of HA 1004 on guinea pig airway smooth muscle contraction were compared to the effects of the calcium...

...Gary J. Grover; Steven Dzwonczyk; Paul G. Sleph A comparison was made of the anti-ischemic effects of dihydropyridine calcium antagonists in isolated globally ischemic rat hearts. Pretreatment with amlodipine, nifedipine, nitrendipine, or nisoldipine reduced reperfusion enzyme (lactate...

...Mark E. Olah; Ralf G. Rahwan This study was undertaken to determine the relative age-dependent responsiveness of the rat aorta to depolarizing (potassium) and receptor-activating (norepinephrine) contractile stimulants, and to the calcium antagonists propyl-methylenedioxyindene (pr-MDI...

... of this intracellular calcium antagonist on cysteamine-induced duodenal ulcers at the same low doses. Duodenal ulcers were induced in rats with a single dose of cysteamine (425 mg/kg, s.c), which produced an 80% ulcer incidence within 24 h without affecting gastric acid concentration. Administration of pr-MDI (10...

...Richard W. Chapman; Gisela Danko; Marvin I.
