Background: Venlafaxine (VEN) is a bicyclic phenylethylamine derivative and possess marked a structural difference from other antidepressant drugs present in the market. It works by eliciting the neurotransmitter action in CNS. It occurs in two enantiomeric forms i.e R and S VEN. After the first pass metabolism, it gets metabolized into more active form O-desmethylvenlafaxine (ODV) which also exist in the enantiomeric forms. So it is important to develop suitable analytical and bioanalytical method for the determination of VEN and its metabolite to quantify them accurately.
Methods and Results: The current review summarizes methods to determine chiral and achiral forms of VEN and ODV. According to the literature, it is clear that most widely used method for the determination of VEN and ODV is liquid chromatography-mass spectroscopy, other methods used for routine analysis include UV spectroscopy, reverse phase high-performance liquid chromatograph with PDA detector. For the determination of enantiomeric forms of VEN and ODV, different chiral columns have been utilized. Capillary electrophoresis with charged cyclodextrins is also used to determine the enantiomeric forms.
Conclusion: Various analytical methods for determining VEN and its metabolite in different matrices have been discussed thoroughly in the present review.
