ABSTRACT
The current work is intended towards the development of a simple, rapid and precise UV-Visible spectrophotometric method for the simultaneous estimation of Donepezil HCI and Memantine HCI present in the marketed formulation using UV simultaneous equation. Distilled water was used as a solvent and the absorbance of the drug was measured at the absorbance maxima(λmax) of Donepezil HCI and Memantine HCI, UV 208nm & 236nm respectively. Calibration curve plotted in concentrationrange10-50μg/ml, 25-125μg/ml exhibited an excellent linear relationship for Donepezil HCI and Memantine HCI. The method was found to comply all the validation parameters as per the ICH guideline. The method showed good reproducibility and recovery with % RSD in the favorable range indicating the sensitivityof the method towards analyte.
Keywords: Donepezil HCI, Memantine HCI, UV-Visible spectrophotometric method.
