Silagra 100 mg is a PDE5 inhibitor, which means it works by blocking the action of the enzyme phosphodiesterase type 5 (PDE5). This enzyme typically restricts blood flow to the penis, preventing an erection. By inhibiting PDE5, Silagra helps relax the blood vessels in the penis, leading to improved blood flow and allowing men to achieve an erection when sexually aroused.
