A. These agents decrease transmembrane calcium current associated in a smooth muscle with long-lasting relaxation
and in a cardiac muscle with a reduction in contractility
B. These agents has a moderate reflex and vascular dilative action caused by the stimulation of sensitive nerve endings
C. Beneficial effects of these agents are related primarily to their hemodynamic effects – decreased heart rate, blood
pressure, and contractility – which decrease myocardial oxygen requirements at rest and during exercise D. These agents increase the permeability of K channels, probably ATP-dependent K channels, that results in stabilizing the membrane potential of excitable cells near the resting potential
A. Less likely to cause gastrointestinal bleeding. B. Less likely to cause diarrhea.
C. Less likely to cause acute renal failure.
D. More likely to reduce inflammation.
E. More likely to prevent further acute attacks
