In medical terminology, what is the meaning of the abbreviation "ac"?

The abbreviation "ac" stands for "ante cibum," which is Latin for "before meals." In medical contexts, this term is commonly used to indicate that a medication should be administered prior to eating. This timing can be significant because certain medications are better absorbed or function more effectively when taken on an empty stomach. Understanding this terminology is crucial for the proper administration of medications, ensuring that patients receive the intended benefits of their prescriptions.
