How does tenormin (for high BP) work ?

Question

Want to know how it helps in controlling High BP. Does it help in thinning the blood ?
Thanks

Answer 1

No it has no thinning effect on the blood.
It works by the following mechanism:
Heart. Beta-blockers bind to beta-adrenoceptors located in cardiac nodal tissue, the conducting system, and contracting myocytes. The heart has both b1 and b2 adrenoceptors, although the predominant receptor type in number and function is b1. These receptors primarily bind norepinephrine that is released from sympathetic adrenergic nerves. Additionally, they bind norepinephrine and epinephrine that circulates in the blood. Beta-blockers prevent the normal ligand (norepinephrine or epinephrine) from binding to the beta-adrenoceptor by competing for the binding site.
In this way it controls heart, rate by slowing it down, and the blood pressure comes down.

Answer 2

tenormin is a beta-adrenergic blocking agent,these drugs interfere with the action adrenaline and other chemicals in the body that affect many body functions. tenormin slows blood flow so the heart and arteries don't have to work so hard.thus lowering your BP.

Answer 3

Tenormin (atenolol) works by blocking the beta receptors in the heart (hence it belongs to the class of drugs called beta-blockers) Blocking the beta receptors makes the heart beat more slowly. This allows the heart to fill more fully, thereby allowing more blood to go around the body with each beat. It is also used to reduce mortality and morbidity post-heart attack, to treat angina and treat arrhythmias
