Chemical stability studies of drugs or compounds are crucial for ensuring that a medication maintains its efficacy and safety throughout its shelf life. These studies evaluate how the drug degrades under various environmental conditions, such as temperature, humidity, and light. Changes in the chemical composition of the drug are examined to identify potential degradation products that could affect its potency, safety, or quality. The data obtained help determine the drug’s expiration date, appropriate storage conditions, and the duration for which the drug remains within specifications. These studies are essential for ensuring that medications are safe and effective until the end of their shelf life.
