In pharmacy, the abbreviation "AC" stands for ante cibum, which is Latin for before meals.
Understanding AC in Pharmacy
When you see "AC" on a prescription or medication label, it indicates that the medication should be taken before eating. This timing is crucial for some drugs because food can affect how they're absorbed or work in your body.
Why is Timing Important?
- Absorption: Some medications are best absorbed on an empty stomach, meaning their effectiveness is decreased when taken with or after food.
- Interaction: Food can interact with some drugs, either increasing or decreasing their effect.
- Effectiveness: Taking medication at the prescribed time ensures the drug has the optimal impact.
Practical Example
If a prescription label reads: "Take 1 tablet AC," it means the patient should take one tablet before eating their meal. It is important to take this medication before consuming food to ensure it works as intended.

Conclusion
"AC" in pharmacy is a specific instruction, indicating that a medication should be taken before meals. This helps ensure that the medication works as intended and is not affected by the presence of food in the digestive system.
