**Core Concept**
Prazosin is a non-selective α1-adrenergic receptor antagonist used in the management of hypertension, benign prostatic hyperplasia, and certain cardiovascular conditions.

**Why the Correct Answer is Right**
Prazosin is primarily used to treat hypertension by blocking α1-adrenergic receptors in the smooth muscle of blood vessels, leading to vasodilation and decreased peripheral resistance. In benign prostatic hyperplasia, prazosin relaxes smooth muscle in the prostate and bladder neck, improving urine flow. Additionally, prazosin has been used off-label to treat post-traumatic stress disorder (PTSD), particularly in patients with nightmares and flashbacks.
