Tadacip 20 mg treats Erectile Dysfunction and helps men gain an erection. Since Tadacip is a PDE-5 inhibitor, it blocks the PDE-5 enzyme and enhances the cyclic Guanosine Monophosphate (cGMP) levels. The enhanced cGMP levels relax the penile muscles, which boosts blood flow in the region, helping men attain a firm erection when they are sexually stimulated. In some cases, the Tadalafil in Tadacip can help manage the symptoms of Pulmonary Hypertension (PH).
