UV Spectrophotometric Method for the Simultaneous Determination of Desloratidine and Pseudoephedrine HCl in Combined Dosage Form

Aims: UV Spectrophotometric Method for the Simultaneous Determination of Desloratidine and Pseudoephedrine HCl in combined Dosage form.
Study Design: A simple, rapid and specific UV spectroscopic method with good sensitivity was developed and validated for the simultaneous determination of Desloratidine and Pseudoephedrine HCl in bulk and pharmaceutical dosage form.
Place and Duration of Study: Department of pharmaceutical Analysis & Quality Assurance, School of Pharmacy, Anurag Group of Institutions, Venkatapur, R.R Dist, Andhra Pradesh, India during February 2013 and April 2013.
Methodology: Vierodt’s (Simultaneous equation) method was performed for Estimation of Desloratidine and Pseudoephedrine HCl in Pharmaceutical dosage form.
Results: In Ethanol the λmax of Desloratidine and Pseudoephedrine HCl was fixed as 240 and 258 nm respectively using a Shimadzu UV-Visible spectrophotometer. In this proposed method both drugs obeyed linearity within the concentration range of 5-30 μg/ml and 80-800 μg/ml for Desloratidine and Pseudoephedrine HCl respectively. The low RSD values indicate good precision and high recovery values indicate accuracy of the proposed method. The proposed method has been applied to the determination of drugs in commercial formulations. Assay results were in good agreement with label claim. The method was validated as per ICH guidliness.
Conclusion: The developed method was simple, accurate, precise, specific, sensitive and reproducible which can be efficiently and easily applied to pharmaceutical dosage forms
