IMPORTANCE OF DRUG EXCIPIENT COMPATIBILITY STUDIES BY USING OR UTILIZING OR EMPLOYING VARIOUS ANALYTICAL TECHNIQUES – AN OVERVIEWAbstract
The interaction/incompatibility of drug excipients is a major concern in formulation generation. Compatibility tests for drug excipients constitute an important step of the production of all dosage forms in the preparation stage. The possible physical and chemical interactions of drugs and excipients can influence chemical, physical, therapeutic properties and the dosage form’s stability. The current review involves a fundamental mode of drug degradation, a process of physical, chemical and biopharmaceutical interaction between drugs and excipients. The study of incompatibility is explored in various thermal and nonthermal methods. Once the interaction form is identified, further steps can be taken to enhance drug and dose stability. Current and potential reviews of case studies relating to drug and excipient interactions and their unavoidable incompatibilities have also been studied to deepen greater information about such drug solution scenarios. From the review, we conclude that the subsequent use of the thermal and nonthermal methods provides information for the drug-excipient interaction, which can aid the production of safe dosage forms by selecting an excipient.
