Cavapro 75 mg contains Vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, commonly used to treat erectile dysfunction (ED) in men. Vardenafil helps to increase blood flow to the penis during sexual stimulation by inhibiting the enzyme PDE5, which plays a key role in the breakdown of cyclic GMP (a molecule involved in vasodilation). This allows men to achieve and maintain an erection sufficient for sexual activity.
