Development and Validation of Ultraviolet Spectrophotometry Methods for Estimated Mixtures of Paracetamol, Acetosal, and Cofeine in Tablet Preparations

Introduction

The use of a combination of two or more analgesic drugs is a common practice in the pharmaceutical industry due to the potential benefits it offers. One of the methods used for multicomponent quantitative analysis in pharmaceutical preparations is derivative spectrophotometry. This method is a transformation of conventional spectrophotometry that can separate the spectrum of overlapping compounds. The aim of this study is to develop and validate derivative spectrophotometry methods to determine paracetamol, acetosal, and cofeine levels in tablet preparations without requiring the separation stage.

Background

Derivative spectrophotometry is a technique that has been widely used in the pharmaceutical industry for the analysis of multicomponent mixtures. This method is based on the principle of differentiating the absorbance spectrum of a sample, which allows for the separation of overlapping peaks. The use of derivative spectrophotometry has several advantages, including increased spectrum resolution, increased sensitivity, and ease of application.

Methodology

The study was conducted by analyzing a mixture of paracetamol, acetosal, and cofeine tablets using zero-crossing techniques in derivative spectrophotometry. Ethanol was used as a solvent in this analysis. The results showed that the zero-crossing technique in the third derivative with a wavelength of 267.6 Nm (Δλ 2) was successfully used to determine the level of paracetamol, while for acetosal, this technique was applied to the third derivative with a wavelength of 236.2 nm (Δλ 2). The cofeine was analyzed in the second derivative with a wavelength of 235.8 Nm (Δλ 16). The analysis showed 101.198%, 105.78%, and 107.74% levels for paracetamol, acetosal, and cofeine, respectively.

Results

The results of the study showed that the developed derivative spectrophotometry method meets the accuracy and precision requirements. This shows that this method can be used to determine paracetamol, acetosal, and cofeine levels in tablet preparations.
