What does "ac" represent in medical terms?

In medical terminology, "ac" is an abbreviation that stands for "ante cibum," which is Latin for "before meals." When a healthcare provider writes a prescription or instructions that include "ac," it signifies that the medication should be taken prior to eating. This is important because the effectiveness of some medications can be influenced by food intake, and taking them on an empty stomach may enhance their absorption or efficacy. For instance, certain medications may require a specific time frame before or after meals to ensure that they work correctly, making the instruction to take them "ac" essential for proper patient care.
