In pharmacokinetics, liberation refers to:

In pharmacokinetics, liberation refers to:

• A. Absorption into the bloodstream
• B. Distribution to tissues
• C. Release of the drug from the dosage form
• D. Metabolism by liver enzymes

Answer: (C)

Liberation is the release of the drug from its dosage form into the surrounding medium, making it available to dissolve. For solid oral forms, this includes disintegration of the tablet or capsule and the subsequent dissolution of the active drug. This step must occur before the drug can be absorbed into the bloodstream, which is the next phase, followed by distribution to tissues and metabolism by liver enzymes. So, liberation specifically refers to releasing the drug from the dosage form, not its absorption, distribution, or metabolism.
