Kamagra 50 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other medications containing sildenafil citrate, such as Viagra, Kamagra 50 mg works by increasing blood flow to the penis during sexual stimulation, enabling men to achieve and maintain an erection.
