Prazosin Hydrochloride, commonly referred to as simply prazosin, and sold under various brand names, is an alpha-adrenergic receptor blocking agent (α1 blocker) medication. Prazosin is most commonly used to lower high blood pressure, or to treat symptoms of an enlarged prostate. Prazosin is also often used as an off-label medication, as a nightmare preventative for those with post-traumatic stress disorder (PTSD). Other uses may include heart failure and Raynaud syndrome.
