Nurse Teaching on Alpha-1 Adrenoceptor Antagonists and Mechanism of Action
Patient was educated on Alpha-1 adrenoceptor antagonists and its mechanism of action as follows: These drugs inhibit the action of catecholamines (adrenaline and noradrenaline) on the Alpha-1 receptors of the blood vessels (both arteries and veins). Action of catecholamines on Alpha-1 receptors result in constriction of arteries and veins. Inhibition of the catecholamine action on these receptors result in relaxation and dilation of arteries and veins. Dilation of arteries results in decreased resistance for the [...]
