Description
Description
Atenolol, a medication commonly found in 100mg tablets, operates as a selective beta-1 receptor antagonist, commonly known as a beta-blocker. Its mechanism of action involves blocking the activation of beta-1 adrenergic receptors in the heart and other target organs. By doing so, Atenolol reduces the heart rate and the force of contraction, which in turn lowers blood pressure. This is achieved by inhibiting the effects of catecholamines, such as norepinephrine, on these receptors, thus decreasing cardiac output and oxygen demand, and ultimately leading to a reduction in blood pressure and improved cardiovascular function.
