Kamagra 100mg is a medication primarily prescribed for the treatment of erectile dysfunction (ED) in men. Kamagra 100 mg main component is sildenafil citrate, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. When a man experiences sexual stimulation, the body releases nitric oxide, which in turn stimulates the production of cyclic guanosine monophosphate (cGMP). This chemical helps to relax the muscles in the penile region, facilitating the flow of blood into the penis and resulting in an erection.
