Kamagra Oral Jelly is a medication used to help treat erectile dysfunction (ED), a condition in which a man has difficulty achieving or maintaining an erection suitable for sexual activity. The active ingredient in Kamagra Oral Jelly is sildenafil citrate, the same medicine found in Viagra. Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection.
