Question

Dr.Tassawer-e-Meran · Accepted Answer

These agents decrease transmembrane calcium current associated in a smooth muscle with long-lasting relaxation

Dr.Tassawer-e-Meran · Answer

and in a cardiac muscle with a reduction in contractility

Dr.Tassawer-e-Meran · Answer

These agents has a moderate reflex and vascular dilative action caused by the stimulation of sensitive nerve endings

Dr.Tassawer-e-Meran · Answer

Beneficial effects of these agents are related primarily to their hemodynamic effects – decreased heart rate, blood

Dr.Tassawer-e-Meran · Answer

pressure, and contractility – which decrease myocardial oxygen requirements at rest and during exercise

Dr.Tassawer-e-Meran · Answer

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
