Analytical Method Development and Validation Of Stability Indicating RP-HPLC Method For Assay and Related Substances of Paracetamol and Caffeine Effervescent Tablets: Review

Abstract

he ongoing, interdependent tasks related to the departments of research and development, quality control, and quality assurance are the creation and validation of analytical methods. Analytical methods are essential for risk management and equivalency assessments. It aids in the development of acceptability standards unique to a product and the consistency of outcomes. Validations establish whether the analytical process is appropriate for the goal for which it was designed. A review of the literature indicates that paracetamol and caffeine can be determined individually or in combination with other medications using analytical techniques based on UV spectroscopy, RP-HPLC, and HPTLC. The parameters were checked for correctness, precision, robustness, and other aspects of analytical validation in accordance with ICH guidelines. The discovered techniques can be applied to the bulk and tablet dosage form analysis of paracetamol and caffeine in effervescent form since they are straight forward, sensitive, and repeatable. The review also outlines the applicability and constraints of numerous published analytical techniques for paracetamol and caffeine analysis. Stability studies have to be conducted on time and in compliance with the standards issued by the World Health Organization, International Conference of Harmonization, and other bodies. The capacity of a pharmaceutical product to meet the physical, chemical, microbiological, toxicological, protective, and informational requirements of a specific formulation in a particular container-closure system is known as its stability. It also ensures that a pharmaceutical product's effectiveness, safety, and performance will be maintained for the duration of its shelf life, which is seen as a need for approval and acceptability. The requirement for ongoing quality and purity monitoring of medications and products gave rise to various stability test techniques. This review covers the various drug substance stability categories as well as the applicability of various techniques for drug substances that are stable, the applicability of various methods used to test the pharmaceutical product's stability, guidelines released to test the pharmaceutical product's stability, protocols for stability testing that outline the essential elements of a well-managed and regulated stability test, and other aspects of stability are all covered in this review. The researcher working on paracetamol and caffeine in effervescent form will greatly benefit from this thorough review study.
