Determination of Allopurinol Levels in Tablet Preparations with Trade Names and Generics by Spectrophotometry of Fourier Transform Infra Red (FTIR)

Introduction

Allopurinol, a widely used medication for treating hyperuricemia and gout, is a crucial drug that requires precise dosing to ensure its effectiveness. One way to guarantee the quality and efficacy of drug preparations is to verify the levels of the active substance contained in them. This study aims to determine the level of allopurinol in tablet preparations with trade and generic names, as well as assessing its suitability with the standards set in the Indonesian Pharmacopoeia.

The Importance of Allopurinol in Gout Treatment

Allopurinol, also known as 1H-Pirazol [3,4-D] Pirimidin-4–ol, is a medication that functions to reduce uric acid levels in the blood. It is essential to ensure the right dose of allopurinol to guarantee its effectiveness in treating gout. The correct dosage of allopurinol can significantly impact the treatment outcome, making it crucial to verify the levels of the active substance in tablet preparations.

Research Methods

In this study, the method used to determine the level of allopurinol is a spectrophotometry of Fourier Transform Infra Red (FTIR). This method involves creating a calibration model with five different concentrations. Measurement is carried out in the range of wave numbers 4000-400 cm^-1, which allows for the analysis of molecular components with high precision. The validation process is carried out to ensure the accuracy of the results, where the absorbance data of each sample is recorded for further analysis.

The FTIR Spectrophotometry Method

The FTIR spectrophotometry method is a non-destructive analytical technique that uses infrared radiation to analyze the molecular structure of a substance. This method is widely used in pharmaceutical analysis due to its high precision and accuracy. The FTIR spectrophotometry method involves measuring the absorbance of infrared radiation by a sample, which is then used to determine the concentration of the substance.

Research Results

The analysis results show that allopurinol levels in generic tablets and trademarks are as follows:

GENERIC Tablet Allopurinol HexPharm Jaya: 101.89 ± 1.50%
GENERIC Tablet Allopurinol Kimia Farma: 98.18 ± 1.20%
Zyloric® Tablet: 100.74 ± 2.09%
Tablet Kolton®: 98.32 ± 2.09%
OMERIC® Tablet: 100.49 ± 2.74%
Alluric® tablets: 97.81 ± 2.00%

Most tablets show that allopurinol levels that meet the Pharmacopoeia Indonesian Edition VI 2020 requirements. The validation of the method shows the results of the acquisition test of 100.01%, with a 0.59% RSD. LOD (Limit of Detection) and LoQ (Limit of Quantification) are found in 1,5703% and 5,2343%, indicating that the FTIR method is accurate and reliable.

Conclusion

This study concluded that the determination of allopurinol levels in tablets can be carried out effectively using the FTIR spectrophotometry method. The results obtained show that allopurinol levels in various tablet preparations are in accordance with the criteria set by the Indonesian Pharmacopoeia. This is important to ensure the safety and effectiveness of treatment for patients who need therapy for reducing gout. With this accurate and high precision method, the quality of drug preparations can be guaranteed, so as to make a major contribution to public health.
