Abstract :
A simple, precise, accurate and economical methods without any extraction step’ The solvent
used was 0.25N sodium hydroxide. Two wavelengths 246.00nm (? max of Labetalol HCl) and 243.48nm
(Isoabsorptive point) were selected for estimation of Labetalol HCl and Simvastatin for Q-absorbance ratio
method. The concentrations of a drugs were determined by a using ratio of Q absorbances at isoabsorptive points
and at the ?-max of Labetalol HCl methods was a successfully applied to pharmaceuticals dosage forms.
