Sildenafil Citrate, sold as Viagra, Revatio and under various other trade names. Sildenafil Citrate is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH).

Since becoming available in 1998, sildenafil has been the prime treatment for erectile dysfunction; its primary competitors on the market are tadalafil (Cialis) and vardenafil (Levitra).
