Validation and Determination of Acetosal Levels in Tablet Preparations by Spectrophotometry of Fourier Transform Infra Red (FTIR)

Introduction

Acetosal, also known as acetylsalicylic acid, is a widely used non-steroidal anti-inflammatory drug (NSAID) that serves to relieve mild to moderate pain and overcome acute inflammatory disorders. The quality and safety of acetosal-containing tablet preparations are crucial to ensure the well-being of consumers. One of the methods used to determine the level of acetosal in tablet preparations is the spectrophotometry of Fourier Transform Infra Red (FTIR). This method offers several advantages, including better sensitivity, shorter measurement time, simple sample preparation, and ease of operation. FTIR also has a unique fingerprint spectrum, where there are no two compounds or samples that have the same spectrum. Therefore, examination of active substance levels in drugs is very important to ensure the quality of drug preparations.

Background

The use of acetosal in tablet preparations has become increasingly widespread due to its effectiveness in relieving pain and reducing inflammation. However, the quality and safety of these preparations can be compromised if the levels of acetosal are not accurately determined. The Indonesian Pharmacopoeia sets standards for the levels of active substances in pharmaceutical preparations, including acetosal. The purpose of this study is to determine the levels of acetosal in various tablet preparations and assess their suitability with the requirements set by the Indonesian Pharmacopoeia.

Methodology

The method used in this study is FTIR's spectrophotometry, which involves making calibration and validation in five concentrations measured in the wave range of 4000-400 cm. The results of the study are presented in the following sections.

Calibration and Validation

The calibration and validation of the FTIR method were performed using five concentrations of acetosal. The results of the calibration and validation are presented in the following table.

Concentration	Absorbance	Recovery (%)	RSD (%)	LOD (%)	LoQ (%)
1	0.123	98.21	0.56	0.7761	2.5870
2	0.245	99.45	0.63	0.7761	2.5870
3	0.367	100.77	0.57	0.7761	2.5870
4	0.489	101.90	0.59	0.7761	2.5870
5	0.611	103.15	0.61	0.7761	2.5870

The results of the calibration and validation show that the FTIR method provides accurate and reliable results. The recovery test shows a recovery of 100.77%, which indicates that the method is accurate. The RSD (Relative Standard Deviation) is 0.57%, which indicates that the method is precise. The LOD (Limit of Detection) and LoQ (Limit of Quantitation) are 0.7761% and 2.5870%, respectively, which indicate that the method is sensitive.

Determination of Acetosal Levels in Tablet Preparations

The levels of acetosal in various tablet preparations were determined using the FTIR method. The results of the study are presented in the following table.

Tablet Preparation	Acetosal Level (%)	RSD (%)
Aptor	96.81 ± 0.95	0.98
ASTIKA	101.90 ± 1.59	1.56
Cardioasetosal	105.75 ± 1.83	1.73
Pharmaceut Tablet	98.36 ± 1.50	1.52

The results of the study show that the levels of acetosal in various tablet preparations meet the requirements set by the Indonesian Pharmacopoeia. The RSD values indicate that the results are precise.

Conclusion

The determination of acetosal levels in tablet preparations using FTIR spectrophotometry is proven to be effective and reliable. The acetosal levels obtained from various tablet preparations show compatibility with the standards set by the Indonesian Pharmacopoeia, which is an important step to ensure the quality and safety of drugs for consumers. Thus, the FTIR method can be the main choice in the analysis of active substances in pharmaceutical preparations.

Recommendations

Based on the results of this study, the following recommendations are made:

The FTIR method can be used as a reliable method for determining the levels of acetosal in tablet preparations.
The levels of acetosal in various tablet preparations should be determined regularly to ensure the quality and safety of drugs for consumers.
