Suhagra 25 mg is a PDE5 inhibitor that works by blocking the enzyme phosphodiesterase type 5 (PDE5). This enzyme typically breaks down cGMP, a substance that helps relax blood vessels in the penis, allowing blood to flow more freely. By inhibiting PDE5, Suhagra helps increase levels of cGMP, improving blood flow to the penis and facilitating an erection in response to sexual stimulation.
