WebAn example of optical isomerism in drugs is the common painkiller Ibuprofen. Ibuprofen consists of two enantiomers, also known as (S+) and (R-) forms. Although both forms have identical boiling points, solubility, and other physical properties, the (R-) form has absolutely no effect on the body. Ibuprofen.
