Which company produces Viagra?

Viagra (sildenafil) is produced by Pfizer, the company that developed the drug and markets Viagra in many countries.

What other companies make sildenafil (generic Viagra)?

After Viagra’s brand exclusivity ended, multiple manufacturers began producing generic sildenafil (often sold as “sildenafil” tablets rather than “Viagra”). The exact makers depend on the country and the specific generic product.

Who makes the active ingredient sildenafil for Viagra and generics?

Viagra tablets contain sildenafil, which is a small-molecule medicine. Brand-name Viagra is associated with Pfizer as the marketer/producer, while generic sildenafil is made by different drug manufacturers under regulatory approvals in each market.
