What must be ensured about drugs in an institutional pharmacy according to inspection guidelines?

In an institutional pharmacy, it is essential that outdated drugs are not stocked. This is a critical aspect of ensuring patient safety and the efficacy of medicinal treatments. When outdated medications are present, there is a risk that patients may be administered products that have diminished potency or could potentially be harmful. Regulatory guidelines and best practices mandate that pharmacies routinely check inventory for expiration dates and remove any expired items from stock.

The goal is to maintain a safe and effective supply of medications, and preventing the stocking of expired drugs is a fundamental part of this responsibility. An institutional pharmacy must adhere to strict standards of practice, which include regular inspections and audits to ensure that all pharmaceuticals are not only within their shelf life but also stored and handled appropriately to maintain their integrity.

Prominently displaying drugs, mixing prescription items with non-prescription items, and only stocking controlled substances do not align with best practices for safe pharmacy operation. These practices could compromise safety, legality, and the appropriate management of medications within the institutional setting. Thus, ensuring that outdated drugs are not stocked stands as the most crucial requirement among the options provided.
