The "dextrorotatory isomer" is the stereoisomer that rotates plane-polarized light to the right (also called the positive (+) enantiomer), and the "levorotatory isomer" is the stereoisomer that rotates plane-polarized light to the left (also known as the negative (-) enantiomer).
therapy, although the dextrorotatory configuration is considered the active form, is not clear.
My own work, however, revealed that (R)-ar-himachalene is dextrorotatory (+3.8) in hexane but levorotatory (-2.4) in chloroform.

The unexpected properties of Plavix[R], the dextrorotatory enantiomer of clopidogrel, ultimately rendered the compound nonobvious over its racemate.
In addition, enantiomers can be categorised by their ability to rotate polarised light in a clockwise or counterclockwise manner--designated as '+' (also known as dextrorotatory) or '-'(levorotatory).
