Conform http://en.wikipedia.org/wiki/Viagra, formula chimică ar fi 1-[4-ethoxy-3-(6, 7-dihydro-1-methyl-
7-oxo-3-propyl-1H-pyrazolo[4, 3-d]pyrimidin-5-yl)
phenylsulfonyl]-4-methylpiperazine (adică C22H30N6O4S).
În http://chemfinder.camsoft.com găseşti mai multe formule ca:
1-(3-(4, 7-Dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo(4, 3-pyridimin-5-yl)-4-ethoxyphenyl)sulfonyl)-4-methyl piperazine
1-[[3-(4, 7-Dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d]pyrimidin-5-yl)-4-ethoxyphenyl]sulfonyl]-4-methylpiperazine, citrate
şi altele, probabil depinzând de firma producătoare.
