Mechanisms of β1-blockers, Calcium-channel Blockers, & α-blockers

The video covers cardiovascular pharmacology, focusing on drugs affecting heart and peripheral receptors. It explains adrenergic receptors, particularly beta-1 and beta-2, and their roles in heart and lung function. The video discusses beta blockers, their effects on heart rate and blood pressure, and potential side effects like exercise intolerance. Calcium channels and their blockers are explored, highlighting their impact on contractility and blood pressure. Finally, alpha receptors and blockers are examined, emphasizing their role in peripheral vasoconstriction and blood pressure regulation.
