SPECTROPHOTOMETRIC MICRO DETERMINATION OF MECLIZINE HYDROCHLORIDE IN THEIR PHARMACEUTICAL FORMULATIONS AND SPIKED PLASMA
Hamid M. Younis and Hany A. Omara*
ABSTRACT
proposed for the rapid determination of meclizine hydrochloride using
bromocressol green (BCG) and bromophenol blue (BPB). The method
consists of extracting the formed ion- associates into chloroform. The
ion -associates exhibit absorption maxima at 417 and 412 nm for BCG
and BPB, respectively. Meclizine HCl can be determined up to 2.6-25
and 2.5-17.5 μg/ml, using BCG and BPB, respectively. The effect of
acidity, reagent concentration, time, solvent and stoichiometric ratio of
the ion- associates were studied. The molar absorptivity and Sandell
sensitivity of the reaction products were calculated. The method was applied to the
determination of the drugs in their pure form or pharmaceutical preparations.
Keywords: Meclizine hydrochloride; Spectrophotometric; bromocressol green (BCG) and bromophenol blue (BPB); Pharmaceutical analysis.
