Question 1 of 5
Which factors affect the gastrointestinal absorption of medicines? (Select all that apply.) Select 4 options.
Correct Answer: A,C,D,E
Rationale: The factors that affect gastrointestinal absorption of medicines include:
A) Blood flow of the mucous lining of the stomach and intestines - Increased blood flow enhances absorption.
C) Enzyme activity - Enzymes can either enhance or inhibit absorption.
D) Gastric pH - pH affects drug solubility and absorption. E) Gastric emptying time - Faster emptying can reduce absorption. These factors directly influence the rate and extent of drug absorption in the gastrointestinal tract. Blood flow affects the transport of drugs, enzymes play a role in drug metabolism and availability, gastric pH influences drug dissolution, and gastric emptying time affects drug exposure to absorption sites. Other choices (B, F, G) are not directly related to gastrointestinal absorption of medicines and are therefore incorrect.
