What is the primary use of drops in pharmacy?

The primary use of drops in pharmacy is for precise measurement of small liquid volumes. This method is particularly beneficial when administering medications that require exact dosages, as the drop size can be consistent and controlled. Using drops allows for accurate dosing in situations where only small amounts of liquid are needed, such as with eye drops, ear drops, or certain liquid medications.

In contrast, the options that suggest applying large volumes, creating solid formulations, or using drops for topical ointments don't accurately capture the typical use of drops in medication dispensing. Drops are specifically designed to deliver small, precise quantities rather than larger volumes or to be employed in solid formulations. This precision in measurement is crucial for ensuring patient safety and medication efficacy.
