SILDENAFIL-ORAL MEDICATION FOR ERECTILE DYSFUNCTION-A REVIEW.

Problem of male erectile dysfunction has been better defined, recognised and being treated in the recent times. However, the intracavernosal injection of vaso-active materials and penile prosthesis implantation were only the viable options available. Sildenafil, which is a specific phosphodiesterase type V inhibitor, enhances erection on sexual arousal by increasing the quantity of cyclic guanosine monophosphate in the corpora cavernosa. This has revolutionized the treatment of erectile dysfunction. Though the drug appears very promising with little side effects, many questions regarding efficacy, safety, misuse and overuse need to be addressed.
