What information do storage conditions for drug products primarily rely on?

Storage conditions for drug products primarily rely on information from the manufacturer because manufacturers are responsible for determining and providing guidelines on how their products should be stored. They conduct extensive research and testing to establish the optimal conditions required to maintain a drug's stability, efficacy, and safety throughout its shelf life. This includes specifics about temperature, humidity, light exposure, and other environmental factors that may impact the drug's chemical composition.

Additionally, manufacturers typically provide this essential information on the drug's packaging or labeling, which healthcare providers and pharmacies must follow to ensure the proper handling and storage of medications. The manufacturer’s data is critical because it is based on controlled studies and conditions directly related to their specific formulations, allowing for accurate guidance on how to preserve the therapeutic integrity of the products.
