Stability testing for complex formulations

I’ve been diving deep into stability testing methods lately, especially for those complex drug formulations that have multiple active ingredients. It’s fascinating how variables like temperature and humidity can impact shelf-life. I’d love to hear what techniques you all use to ensure our formulations are as stable and effective as possible over time.

Have you tried utilizing accelerated stability testing techniques — we often use conditions like increased temperature and humidity to foresee how our formulations might behave over time… I found that keeping a close eye on the interaction between active ingredients during these tests has really helped in predicting actual shelf-life. It’s a game-changer for complex formulations.

It’s interesting to see how stability can shift; I once had a formulation that looked great at first but failed during long-term testing. I’ve found that incorporating a small percentage of excipients can help mitigate some of the issues with complex active ingredients. @philipK56, have you found any specific excipients that work well for your formulations?
