We get so many questions regarding the difference between Acomplia, Rimonabant, and Zimulti, that we decided to post our answer here as a service to all those seeking an explanation.
Rimonabant is the official brand name given from the manufacturer, Sanofi-Aventis. Acomplia, which seems to gain more popularity day by day, is the trade name of Rimonabant (which is the name used in 18 countries, as of 2007).
If approved in the USA, it will be marketed under the name Zimulti.
Futher names, Riobant, Slimona, and Rimoslim are generic forms available in India.
