What does the abbreviation "a.c" indicate in a medication administration schedule?

The abbreviation "a.c." stands for "ante cibum," which is Latin for "before meals." This notation is often used in medical contexts to instruct that a medication should be administered prior to eating to ensure optimal absorption and effectiveness. It's particularly relevant for medications that may have a different impact on the body depending on whether food is present in the digestive system. Understanding these abbreviations helps healthcare professionals accurately follow medication administration protocols and enhances patient care by ensuring that medications are taken at the appropriate times.
