Beta blocker
Beta blockers, also written β-blockers, are a class of medications that are predominately used to manage abnormal heart rhythms, and to protect the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention).They are also widely used to treat high blood pressure (hypertension), although they are no longer the first choice for initial treatment of most patients.

Drug class
alpha blocker
Alpha-blockers, also known as α-blockers or α-adrenoreceptor antagonists, are a class of pharmacological agents that act as antagonists on α-adrenergic receptors (α-adrenoceptors).

Historically, alpha-blockers were used as a tool for pharmacologic research to develop a greater understanding of the autonomic nervous system. Using alpha blockers, scientists began characterizing arterial blood pressure and central vasomotor control in the autonomic nervous system.Today, they can be used as clinical treatments for a limited number of diseases.
