Which of these drugs should be stored in the refrigerator?

The correct choice is that liquids should be stored in the refrigerator because certain liquid medications require refrigeration to maintain their stability and efficacy. Many injectable medications, oral suspensions, and some antibiotics, for example, can lose potency or become ineffective if they are not stored at the recommended temperatures. Refrigeration helps preserve the chemical composition of these medications and ensures they remain safe and effective for patient use.

On the other hand, ointments, eye drops, and tablets generally do not require refrigeration and can be stored at room temperature. Ointments often have a stable formulation that can withstand warmer conditions. Eye drops may have specific storage requirements, but most do not necessitate refrigeration; some should be stored upright and protected from light. Tablets are typically stable at room temperature and do not require refrigeration, making them suitable for standard medication storage.
