In pharmacology, alpha adrenergic blockers are "drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma."[1] They are also used for benign prostatic hyperplasia.

Naftopidil is more selective for the alpha-1a adrenergic receptor and has been used to treat benign prostatic hyperplasia.[2] Vascular drug toxicity may be less with tamsulosin due to more selectivity to α1-A and α1-D adrenergic receptors according to a meta-analysis supported by Boehringer Ingelheim Pharmaceuticals, the maker of tamsulosin.[3]
