Sildenafil (Fildena), commonly known by its brand name Viagra, is a medication used to treat erectile dysfunction (ED) in men. It belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis, thereby helping to achieve and maintain an erection.

Sildenafil is typically used as a short-term solution to manage the symptoms of ED. It can be taken as needed before sexual activity or in some cases, as a daily low-dose medication. It provides temporary relief by facilitating erections during the drug's effectiveness, which typically lasts for a few hours.
