Silagra 100, containing sildenafil, is a widely used medication for treating erectile dysfunction (ED) in men. ED can negatively affect a man's overall well-being, leading to difficulty in achieving and maintaining an erection during sensual stimulation. Silagra 100 Mg belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the genital area, helping men respond naturally to sensual stimuli. During arousal, nitric oxide triggers the production of cyclic guanosine monophosphate (cGMP), which relaxes muscles and enhances blood flow for improved performance.
