“…Side effects of angiotensinconverting enzyme inhibitors include chronic cough, urticaria, and rhinitis. Antihypertensives that block autonomic preganglionic nicotinic receptors, a-1 adrenergic receptor antagonists (doxazosin, silodosin, prazosin, tamsulosin, alfuzosin, terazosin), a-2 adrenergic receptor antagonists (mianserin) and some b-adrenergic receptor antagonists (carvedilol) have all been associated with nasal obstruction [Settipane and Charnock, 2007;Curb et al 1988]. Methyldopa is an alpha-adrenergic agonist psychoactive drug used as a sympatholytic or antihypertensive.…”
