Silagra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil helps increase blood flow to the penis, enabling a man to achieve and sustain an erection when sexually stimulated. Silagra 100 contains sildenafil citrate, which is the same active ingredient found in the brand-name medication Viagra. Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to an increase in the levels of cyclic guanosine monophosphate (cGMP). This, in turn, relaxes the smooth muscles of the blood vessels in the penis, allowing increased blood flow and facilitating an erection. Silagra 100 mg is a relatively high dosage, and the appropriate dosage should be determined by a healthcare professional based on factors such as the severity of erectile dysfunction,
