What does the abbreviation a.c. mean in pharmacology?

The abbreviation "a.c." in pharmacology stands for "ante cibum," which is derived from Latin and translates to "before meals." This term is commonly used in prescriptions and medication instructions to indicate that a patient should take a medication prior to eating. This can be particularly important for certain medications that are better absorbed on an empty stomach or when food might interfere with their efficacy.

Understanding these abbreviations is essential for accurately following prescription instructions and ensuring that medications are taken in a manner that maximizes their effectiveness.
