Aildenafil
Aildenafil
Chemical compound
Aildenafil (methisosildenafil) is a synthetic drug that is a structural analog of sildenafil (Viagra).[1] It was first reported in 2003.[2] Like sildenafil, aildenafil is a phosphodiesterase type 5 inhibitor.
Aildenafil has been found as an adulterant in a variety of supplements which are sold as "natural" or "herbal" sexual enhancement products.[3][4][5][6][7] The United States Food and Drug Administration has warned consumers that any sexual enhancement product that claims to work as well as prescription products is likely to contain such a contaminant.[8]
Aildenafil is approved for use in China.[9]
