Overview
Prazon (Prazosin) Tablet 1mg is a veterinary-use alpha-1 adrenergic antagonist prescribed to manage urinary tract disorders and systemic hypertension in dogs and cats. It works by relaxing smooth muscle in blood vessels and the urinary tract, making it easier for pets to pass urine and reducing blood pressure. Prazosin is often used in cases of functional urethral obstruction, prostatic disease, or as adjunctive therapy for congestive heart failure. It is prescribed off-label under veterinary supervision.

- Relaxes urethral and bladder sphincter muscles to improve urine flow
- Reduces systemic and pulmonary blood pressure
- Supports treatment of congestive heart failure when standard therapies are insufficient
