15 Questions
What is the absorption rate constant?
The rate constant that accounts for disintegration, dissolution, and absorption in drug absorption
What needs to happen before a drug in a solid dosage form can be absorbed into the systemic circulation?
The drug needs to be in solution after disintegration and dissolution
What does a larger absorption rate constant result in?
Faster rate of drug absorption
What is the operative rate constant that accounts for all necessary steps required for drug absorption?
Absorption rate constant

True
Tablets and capsules have to dissolve before the drug can be absorbed into the systemic circulation
True
The absorption rate constant (ka) has units of time-1
