Kamagra 100 is a medication commonly used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in several well-known ED treatments. Kamagra 100 works by increasing blood flow to the penis when a man is sexually stimulated, helping him achieve and maintain a firm erection. 

It does this by relaxing the blood vessels and supporting smoother circulation in the genital area. Typically taken about 30–60 minutes before sexual activity, its effects may last for several hours. Kamagra 100 should only be used under medical guidance for safety and effectiveness.
