What is the absorption rate constant?
What is the absorption rate constant?
- The rate at which the drug appears in the systemic circulation after drug administration
- The rate at which the drug is distributed to different parts of the body
- The rate at which the drug is eliminated from the body
- The rate constant that accounts for disintegration, dissolution, and absorption in drug absorption (correct)
What needs to happen before a drug in a solid dosage form can be absorbed into the systemic circulation?
What needs to happen before a drug in a solid dosage form can be absorbed into the systemic circulation?
- The drug needs to be eliminated from the body
- The drug needs to undergo metabolism in the liver
- The drug needs to be in solution after disintegration and dissolution (correct)
- The drug needs to be distributed to different parts of the body
What does a larger absorption rate constant result in?
What does a larger absorption rate constant result in?
- Faster rate of drug absorption (correct)
- Slower rate of drug absorption
- No effect on the rate of drug absorption
- Faster rate of drug elimination
