What Is Terazosin HCL 5mg?
Terazosin HCL is an alpha-1 adrenergic blocker, sold under the brand name Hytrin. It works by relaxing smooth muscle in the prostate, bladder neck, and blood vessels. This helps improve urine flow in men with benign prostatic hyperplasia (BPH) and lowers blood pressure in people with hypertension. Terazosin is taken as a capsule, typically once daily, and requires a prescription.
