An Overview on Stability of Extemporaneously Prepared Pharmaceutical Suspension

Abstract

Aim: The aim of this study was to write review on stability studies of extemporaneous preparations. Materials and methods: Different methods are used for checking stability studies, depending on the nature of the preparations, like visual inspection, pH checking, different temperature storage, and HPLC. Results: It was found that the stability concern with the pharmaceutical suspensions includes the variation in both physical and chemical properties. Therefore, it is most important that formulator must ensure the efficacy of the formulation throughout the shelf life period. In this review article, method used for stability checking is valid and up to mark, so patient can use these extemporaneous preparations according to recommended period of time. Conclusion: We can conclude of our Stress studies that these suspensions cannot be stored over long period of time (average 90-120 days); but they are stable below 120 days (depending on the preparation) so we can have used these preparations because there is no stability issue if used in within recommended time-period, undeniably extemporaneously prepared suspensions can be a helpful for pediatric, geriatric and unconscious patients in drug dosing.
