Alpha antagonist drugs

These drugs block the actions of adrenergic drugs at alpha (α) or beta (β) adrenergic receptors. 1. Alpha Blocker Alpha antagonist are

Alpha antagonist drugs block alpha-1 and alpha-2 receptors, inhibiting their activation by catecholamines and related agonists. Alpha antagonists include phentolamine and phenoxybenzamine . Phentolamine, an alpha-1 and alpha-2 receptor blocker, can be used in cases of cocaine-induced hypertension.

Phenoxybenzamine (a nonselective alpha-antagonist) is the usual drug of choice; prazosin, terazosin, and doxazosin (selective alpha-1-antagonists) are

There are two types of alpha-adrenergic receptors, alpha 1 (on the vascular smooth muscle) and alpha 2 (on the vascular smooth muscle and sympathetic nerve terminals). Alpha-adrenoreceptor antagonists are classed either as non-selective alpha adrenoreceptor antagonists, alpha1-selective antagonists, alpha2-selective antagonists and ergot
