ⓘ 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.
Historically, alpha-blockers have been used as a tool for pharmacological research to develop a better understanding of the autonomic nervous system. Using alpha-blockers, scientists began characterizing arterial pressure and Central vasomotor control in the autonomic nervous system. Today they can be used as clinical treatment of a limited number of diseases.
Although alpha-blockers can treat only a small number of diseases, some of them have clinical application, for example, the ability to treat hypertension, Raynauds disease, and erectile dysfunction. Generally speaking, all of these features of the procedure by binding with α-blocker for alpha receptors in arteries and smooth muscles. Ultimately, depending on the type of alpha receptors relaxes smooth muscle and blood vessels, which increases the flow of fluid in these entities.
