Approved drug
granisetron is an approved drug (FDA (1993), EMA (2012))
Compound class: Synthetic organic
Comment: There is some ambiguity in that the FDA label specifies 1-methyl-N-[(1R,3r,5S)-9-methyl-9-azabicyclo[3.3.1]non-3-yl]-1H-indazole-3-carboxamide. The closest to this in PubChem is the 1S, 5R, as shown. However, the majority of the bioactivity data is linked to the enantiomer CID 3510.
