10 Questions
What is the main goal of clinical pharmacokinetics?
To design individualized dosage regimens that optimize therapeutic response and minimize adverse reactions
What phenomenon occurs when steady-state concentrations increase more than expected after a dosage increase?
Saturable or Michaelis-Menten pharmacokinetics
What type of pharmacokinetics do drugs like valproic acid and disopyramide exhibit?
Saturable plasma protein binding
Why are drugs that exhibit nonlinear pharmacokinetics difficult to dose correctly?
Because their pharmacokinetics are unpredictable
What can be inferred about the pharmacokinetics of Curacillin based on the provided data?
It follows linear pharmacokinetics
What is the definition of clearance in pharmacokinetics?
The volume of serum or blood completely cleared of the drug per unit time
What is the formula to calculate the maintenance dose (MD) of a drug?
MD = Cl x Css
Which of the following organs is responsible for drug metabolism?
Liver
What is the formula to calculate the extraction ratio (ER) of a drug?
ER = (Cin - Cout)/Cin
What is the total clearance (Cl) of a drug that is metabolized by the liver and eliminated by the kidney?
Cl = ClH + ClR
This quiz covers the application of pharmacokinetic concepts and principles in humans to design individualized dosage regimens. It also explores pharmacokinetics, the study of the absorption, distribution, metabolism, and excretion of drugs.
