Tadarise Pro 20 mg is a medication used to treat erectile dysfunction (ED). It contains tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadarise Pro 20 mg increases blood flow to the penis by inhibiting PDE5. This enzyme restricts blood flow, so by blocking it, tadalafil helps relax the blood vessels, facilitating an erection when sexually aroused.
