Drug Absorption · Pharmacology

Which factor is most likely to delay the absorption of a drug that is primarily absorbed in the upper small intestine?

  1. Increased intestinal blood flow
  2. Co-administration with a large, fatty meal
  3. Rapid gastric emptying
  4. Taking the drug with a full glass of water
Show answer and explanation

Correct answer: Co-administration with a large, fatty meal

Fatty meals slow down gastric emptying, delaying the delivery of the drug to the small intestine. This results in a slower rate of absorption and a delayed peak plasma concentration ($T_{max}$).
