Alpha 2 antagonist drugs

This chapter reviews the actions of antidepressant drugs that work as alpha 2 antagonists (ie, mirtazapine) or as serotonin antagonist/reuptake inhibitors (

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.

Adrenergic antagonist medications inhibit the Alpha-1, Alpha-2, Beta-1, and Beta-2 receptors. The effects of inhibition of each receptor are explained further below. Alpha-1 antagonists: Alpha-1 antagonists are primarily used to relax smooth muscle in the bladder and cause vasodilation. Examples include the following:

Alpha adrenergic receptor agents include agonists and antagonists that bind to the alpha-1 and alpha-2 adrenergic receptors.

While Alpha-2 antagonists have few clinical uses, alpha-1 and nonselective alpha antagonists are used for their ability to cause vasodilation

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
