Introduction

The use of combination drugs in the form of cream preparations has become increasingly popular in the pharmaceutical industry. Acetic hydrocortisone and chloramphenicol are two commonly used compounds in these preparations. However, determining the levels of these compounds simultaneously in cream preparations can be a challenging task. This study aims to determine the levels of acetic hydrocortisone and chloramphenicol in cream preparations using the ultraviolet spectrophotometry method, specifically through the Mean Centering of Ratio Spectra (MCR) approach.

The Importance of Determining Simultaneous Levels of Acetic Hydrocortisone and Chloramphenicol

Determining the levels of acetic hydrocortisone and chloramphenicol in cream preparations is crucial for ensuring the quality and efficacy of these products. The simultaneous determination of these compounds can provide valuable information on the stability and shelf life of the cream preparations. Moreover, it can also help in identifying any potential interactions between the two compounds, which can affect their therapeutic efficacy.

Research Methodology

This study took a chloramfecort cream sample, each containing 25 mg of acetate hydrocortisone and 20 mg of chloramphenicol. To measure the levels of the two substances, the MCR method was applied by measurement at a wavelength of 241 Nm for acetate hydrochortisone and 273 nm for chloramphenicol. Calculation of levels was done using the Matlab application that provides high accuracy in data analysis.

Characteristics of the MCR Method

The MCR method has several characteristics that make it an effective and reliable method for determining the levels of acetic hydrocortisone and chloramphenicol in cream preparations. These characteristics include:

Quantitation Limit (LoQ): The LoQ is the minimum concentration of a substance that can be quantitatively determined using the MCR method. In this study, the LoQ for acetate hydrocortisone was recorded at 2.1167 μg/ml, while the LoQ for chloramphenicol was recorded at 3.4871 μg/ml.
Accuracy: The accuracy of the MCR method was determined by comparing the measured levels of acetic hydrocortisone and chloramphenicol with the actual levels. The accuracy of the MCR method was found to be 100.7178% for acetate hydrocortisone and 99.4867% for chloramphenicol.
Precision: The precision of the MCR method was determined by calculating the relative standard deviation (RSD) of the measured levels of acetic hydrocortisone and chloramphenicol. The precision of the MCR method was found to be 0.6222% for acetate hydrocortisone and 0.7429% for chloramphenicol.
Selectivity: The selectivity of the MCR method was determined by analyzing the spectra of the cream preparations and identifying any potential interferences. The selectivity of the MCR method was found to be high, with no significant interferences detected.
