Kamagra 100 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhi***ors. When a man is sexually aroused, Kamagra 100 helps increase blood flow to the penis, facilitating an erection. It works by inhi***ing the enzyme PDE5, which normally breaks down a substance called cyclic guanosine monophosphate (cGMP).

By blocking PDE5, Kamagra 100 allows cGMP to accumulate, leading to smooth muscle relaxation in the blood vessels of the penis and improved erectile function. However, it requires sexual stimulation to be effective.
