Lopressor and Mechanism of Action

Patient was educated on Lopressor and its mechanism of action as follows: Lopressor is a selective Beta-1 blocker that inhibits the action of catecholamines (adrenaline and noradrenaline) on the Beta-1 receptors. Inhibition of Beta-1 receptors result in slowing of heart rate and decreases the force of contraction of heart muscle. Reduction in heart rate contributes to low BP. Decrease in the force of contraction of heart muscle will bring about reduction in the amount of [...]
