Q: Drugs in suspensions and semi-solid formulations always degrade by:
  • A. First order kinetics
  • B. Second order kinetics
  • C. Zero order kinetics
  • D. Non-linear kinetics
Correct Answer: Option C - Drug in suspensions and semi-solid formulations always degrade by zero order kinetics. • Zero order kinetics undergo constant elimination regardless of the concentrations following a linear elimination phase as the system becomes saturated. • Zero order drug is a constant amount of drug is eliminated per unit time, the suspended drug reservoir ensures constant concentration.
C. Drug in suspensions and semi-solid formulations always degrade by zero order kinetics. • Zero order kinetics undergo constant elimination regardless of the concentrations following a linear elimination phase as the system becomes saturated. • Zero order drug is a constant amount of drug is eliminated per unit time, the suspended drug reservoir ensures constant concentration.
