What does the abbreviation 'ac' stand for in relation to meal timing for medication administration?

The abbreviation 'ac' stands for "ante cibum," which is a Latin term meaning "before meals." In the context of medication administration, this indicates that the medication should be taken prior to eating, typically to enhance absorption or minimize potential interactions with food that could affect the medication's effectiveness. Understanding this terminology is crucial for pharmacists and pharmacy technicians to ensure that patients receive their medications at the appropriate times for optimal effectiveness and safety.
