Bunazosin (E-643) is a quinazoline derivative with a1-adrenoceptor blocking activity. It has been clinically used both as a systemic antihypertensive as well as an ocular hypotensive drug. The major adverse effect associated with the use of bunazosin is orthostatic hypotension or its consequences (e.g. dizziness). Others adverse effects include headache, sweating, nausea, dry mouth, abdominal pain, diarrhea, and constipation. The effects of Bunazosin may be enhanced by diuretics and other antihypertensive agents and decreased by Rifampicin.
