Cenforce tablet containing Sildenafil is primarily used to treat erectile dysfunction by enhancing blood flow to the penis. It is important to take it as directed, typically 30 to 60 minutes before sexual activity, and be aware of potential side effects like headaches or dizziness. Sildenafil inhibits the phosphodiesterase type 5 (PDE5) enzymes, increasing cyclic guanosine monophosphate (cGMP) levels.
