Kamagra is a brand name for a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is also found in Viagra. Kamagra works by increasing blood flow to the penis during sexual stimulation, thus helping men achieve and maintain an erection. However, it's essential to use Kamagra or any medication containing sildenafil citrate under the guidance of a healthcare professional, as it can have side effects and interactions with other medications. Additionally, it's crucial to purchase medications like Kamagra from reputable sources to ensure safety and effectiveness.
