Suhagra 100 mg is a tablet used to treat erectile dysfunction (ED) in men. It contains 100 mg sildenafil citrate, a PDE5 inhibitor that relaxes blood‑vessel smooth muscle in the penis and increases blood flow, so a man can achieve and maintain a firm erection when sexually stimulated. It does not cause automatic erections and only works with arousal; it may also be used, in some cases, to treat pulmonary arterial hypertension (PAH).
