Men are typically prescribed Kamagra 100mg to address erectile dysfunction (ED). The key component of Kamagra 100 mg is sildenafil citrate, which functions as a phosphodiesterase type 5 (PDE5) inhibitor. When a man experiences sexual arousal, his body releases nitric oxide, leading to the production of cyclic guanosine monophosphate (cGMP). cGMP helps relax the penile muscles, facilitating increased blood flow to the penis and resulting in an erection.
