Medicine storage is an essential component of pharmaceutical quality assurance because inappropriate storage conditions and inadequate inventory practices may affect medicine quality, safety, and availability. This study aimed to analyze the implementation of medicine storage practices in the pharmacy warehouse of Dr. Hasri Ainun Habibie Regional Hospital. A qualitative descriptive approach was employed. Data were collected through direct observation, interviews, and document review involving three informants consisting of the Head of the Pharmacy Installation, the pharmacy warehouse officer in charge, and pharmaceutical technical staff. Data were analyzed descriptively by comparing observed practices with applicable Good Storage Practices (GSP) principles. The findings showed that medicines were generally organized according to type, dosage form, storage requirements, and specific categories, with FEFO applied for stock rotation. Incoming medicines were checked based on purchase documents, quantity, batch number, expiration date, and physical condition, while stock cards supported inventory monitoring. The storage room was maintained in a clean and orderly condition, with adequate ventilation and lighting, temperature control, and protection against insects and rodents. Storage cabinets and medicine refrigerators were also maintained properly, and expired medicines were separated from active stock. However, LASA medicines were not consistently provided with specific labels, and some procedures required greater standardization to ensure consistent implementation. The study concludes that medicine storage practices were generally implemented appropriately, although improvements are needed in LASA identification, standardization of operational procedures, continuous monitoring, and personnel competency to strengthen pharmaceutical quality assurance.
