Composition

• Prazosin Hydrochloride 5 mg (Extended Release)

Indications

Razosin ER Tablet is indicated for:

• Adjunct therapy in congestive heart failure

• Benign prostatic hyperplasia (BPH) symptom relief (off-label use)

Mechanism of Action

Prazosin selectively blocks postsynaptic alpha-1 adrenergic receptors in vascular smooth muscle. This causes vasodilation of both arteries and veins, reducing peripheral vascular resistance and lowering blood pressure. The extended-release formulation ensures smoother plasma levels and reduces fluctuations that may cause hypotension or dizziness.
