Which abbreviation indicates a frequency of taking medication at specific mealtimes?

The abbreviation that represents taking medication at specific mealtimes is "ac," which stands for "ante cibum" in Latin, translating to "before meals." This is often used in prescriptions to indicate that a medication should be taken before eating, thereby ensuring that the medication is absorbed effectively and its action is optimized during or after the meal.

Understanding the context of medication administration is essential for proper patient care. Medications taken "ac" may need to be timed before meals to enhance their effectiveness, while other abbreviations denote different frequencies or timing that may not be linked specifically to meal times.
