Silagra is a medication used to treat erectile dysfunction. It contains the active ingredient sildenafil which belongs to a class of phosphodiesterase type 5 inhibitors. The drug works by enhancing the natural nitric oxide pathway which increases cyclic guanosine monophosphate levels in penile tissue. This relaxation of smooth muscle leads to increased blood flow and facilitates an erection when sexual stimulation occurs. The therapeutic effect is specific to improving erectile function without affecting hormonal levels or libido. The systemic absorption and targeted action in the pelvic vasculature underlie its mechanism of action.
