  1. Change of the chemical composition of the drug
  2. Increased gastric pH
  3. Decreased strength of the drug

3. What age-related changes in the stomach can cause increased drug absorption and possibly drug toxicity?

  1. Decreased gastric motility
  2. Gastric reflux disease
  3. Inability of gastric cells to transport the drug
  4. Decreased peristalsis

ANS: A
Decreased motility leaves the drug in contact with the gastric mucosa for a longer period of time, which leads to increased absorption. Peristalsis is rhythmic movements of the bowels.
