Two spectroscopic methods for simultaneous estimation of Indapamide and Nebivolol hydrochloride in combined tablet
dosage form have been developed. The first method is simultaneous equations method which involves the formation of simultaneous
equations at 241.6 nm (?-max of Indapamide) and 281.5 nm (?-max of Nebivolol hydrochloride). The linearity
was observed in the concentration range of 2-12 ?g/ml and 10-50 ?g/ml respectively for Indapamide and Nebivolol hydrochloride.
The second method is Q-analysis method (Q-absorbance ratio), which involves the formation of Q-absorbance
equation at 274 nm (Iso-absorptive point) and 281.5 nm (?-max of Nebivolol hydrochloride). In this method the linearity was
evaluated over the concentration range of 2-20?g/ml for both the drugs. The accuracy of the methods were assessed by recovery
studies and was found to be 100.04 ?0.0607 and 99.85?0.94 for simultaneous equations method and 101.12?1.57and
98.26?1.18 for Q-absorbance ratio method for Indapamide and Nebivolol hydrochloride respectively. The proposed methods
are simple, accurate, precise, rapid and cost effective. Therefore the proposed methods can be used for routine analysis of
both drugs in bulk as well as in pharmaceutical formulations.
