Rapid absorption into the bloodstreamDrug comes into contact with stomach acidsExtensive metabolism by the liver before reaching circulationAllows administration of a wide range of doses

4.Which statement accurately describes the action of potassium channel openers?

These drugs reduce the transmembrane calcium current in smooth muscle, leading to prolonged relaxation.These drugs produce a mild reflex response and cause vascular dilation by activating sensitive nerve endings.Their therapeutic benefits mainly arise from hemodynamic effects such as lowering heart rate and blood pressure.They enhance potassium channel permeability, likely targeting ATP-sensitive channels, thereby stabilizing the resting membrane potential of excitable cells.

5.Which medication lowers blood pressure by targeting the vasomotor centers within the central nervous system?

LabetalolClonidineEnalaprilNifedipine
