Sildenafil is used to treat male sexual perform issues (impotence or erectile dysfunction -ED). Sildenafil is administered orally for the remedy of erectile dysfunction (ED). Knowledge are limited concerning the use of sildenafil in women with neurogenic sexual dysfunction, resembling those with spinal cord damage or multiple sclerosis. The role, if any, of sildenafil within the management of sexual dysfunction in ladies remains to be established. Specific drug interplay research have not been performed with sildenafil and different platelet-aggregation inhibitors comparable to dipyridamole, ticlopidine, or clopidogrel.

In some cases, a reduction in sildenafil dosage is advisable, while in different instances, concomitant use of the medicine must be avoided.

Due to the excessive incidence of ED in cardiovascular patients and the general efficacy of selective PDE sort 5 inhibitors, many such patients may benefit from remedy with the drug.
