– Contamination: Introduction of microbes can lead to the growth of bacteria or mold, which can degrade the antibiotic or produce harmful by-products.
Understanding Expiration Dates
The expiration date on a medication, including liquid antibiotics, is the date by which the manufacturer guarantees the full potency and safety of the drug. This date is determined through stability studies, where batches of the drug are stored under various conditions and tested periodically for their chemical and physical properties. Expiration dates are not the date after which the drug becomes dangerous to use, but rather the date after which the manufacturer cannot guarantee its effectiveness.
Stability Studies
Stability studies involve testing the drug under real-time conditions (at room temperature, under refrigeration, etc.) and accelerated conditions (high temperature, high humidity) to predict how long the drug will remain stable. These studies help in establishing the expiration date and the recommended storage conditions for the drug.
Real-Time and Accelerated Stability Studies
- Real-time stability studies are conducted under the recommended storage conditions for the drug and can take several years to complete.
