Drug-Excipient, In-Process, And Packaging Compatibility Studies In Pharmaceutical Development: A Comprehensive Review

Abstract

Compatibility studies play a crucial role in pharmaceutical product development by identifying, quantifying, and predicting potential interactions and incompatibilities between components in a formulation. These interactions can lead to changes in the physical, chemical, or therapeutic properties of the dosage form, potentially affecting its stability, safety, and efficacy. The primary objective of compatibility studies is to select compatible excipients, determine stable storage conditions, and ensure the overall quality, safety, and efficacy of the final product. This review delves into the various types of incompatibilities, their causes, and potential remedies. It also provides detailed information on drug-excipient, in-process component, and finished product-packaging material compatibility studies, along with their respective protocols. Drug-excipient compatibility studies, in particular, are a critical phase in the pre-formulation stage of drug development. Thermal and non-thermal methods are employed to evaluate the suitability and compatibility of excipients for developing stable dosage forms.
