Viagra pills. Viagra pills of varying dosage spilling from a bottle. Viagra is the trade name for the drug sildenafil citrate. It is the first oral pill for erectile dysfunction, a type of male impotence. Viagra affects the response to sexual stimulation, enhancing the effect of nitric oxide, a chemical released in response to stimulation. This causes smooth muscle relaxation, allowing blood to enter the penis, resulting in erection. The recommended dose is one 50 mg tablet one hour before sexual activity. Viagra is made by Pfizer pharmaceuticals.
