Sildigra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil is the primary active ingredient in Sildigra 100 mg. It works by increasing blood flow to the penis when a man is sexually aroused. This enhanced blood flow helps to achieve and maintain a firm and lasting erection, thereby addressing the symptoms of ED.
