Several processes enable a drug to reach a specific concentration in the body. Together they are called dynamic equilibrium. What are these processes? (Select one that does not apply.)

  • A. Distribution to the active site
  • B. Biotransformation
  • C. Absorption from the muscle
  • D. Excretion
Correct Answer: C

Rationale: The actual concentration that a drug reaches in the body results from a dynamic equilibrium involving several processes: Absorption from the site of entry (can be from the muscle, the gastrointestinal (GI) tract if taken orally, of the subcutaneous tissue if given by that route); Distribution to the active site; biotransformation (metabolism) in the liver; excretion from the body. Interaction with other drugs is not part of the dynamic equilibrium.

  • C. 400 gtt/min
