The abbreviation "ac" is most commonly used to indicate what?

The abbreviation "ac" stands for "ante cibum," which is a Latin term that translates to "before meals." This is a commonly used abbreviation in medical and pharmaceutical settings to instruct patients on when to take certain medications. For instance, a prescription might state that a medication should be taken ac to maximize its effectiveness and enhance absorption during digestion, as some medications can have better bioavailability when taken on an empty stomach. Understanding this abbreviation is crucial for pharmacy technicians, as they provide guidance on medication administration and ensure patients adhere to their prescribed regimens for optimal therapeutic outcomes.
