Penn Foster Pharmacology Questions
and Answers 100% Pass
What is first-pass metabolism?
✔✔ The process where a drug is metabolized by the liver before it reaches systemic circulation,
reducing its bioavailability.
What is the role of plasma protein binding in drug action?
✔✔ Drugs that bind to plasma proteins in the bloodstream can be temporarily inactive and are
released slowly to exert their effects.
What is meant by titration in pharmacology?
✔✔ The gradual adjustment of drug dosage to achieve the optimal therapeutic effect while
minimizing side effects.
What is the significance of a drug's therapeutic window?
✔✔ The range of drug concentrations in the blood where the drug is effective without being
toxic.
1
,What are prodrugs and how do they function?
✔✔ Prodrugs are inactive drugs that become active only after undergoing metabolism within the
body.
What does receptor downregulation mean in pharmacology?
✔✔ The process where prolonged exposure to a drug decreases the number of receptors
available, reducing the drug's effectiveness.
What is pharmacogenomics?
✔✔ The study of how an individual's genetic makeup affects their response to drugs, aiming to
tailor treatments to each person.
What are dose-dependent side effects?
✔✔ Side effects that increase in severity with higher doses of a drug.
What is the purpose of a loading dose?
✔✔ To rapidly achieve therapeutic drug levels in the body, especially for drugs with a long half-
life.
2
,What does bioequivalence mean?
✔✔ A term indicating that two drug products release the same amount of active ingredient into
the bloodstream at the same rate and extent.
What is receptor desensitization?
✔✔ A phenomenon where continuous exposure to a drug leads to a decreased response from the
receptors over time.
What is pharmacokinetic tolerance?
✔✔ When the body becomes more efficient at metabolizing a drug, leading to reduced drug
levels and effectiveness.
How does food-drug interaction affect drug efficacy?
✔✔ Food can alter the absorption, metabolism, or excretion of a drug, potentially enhancing or
diminishing its therapeutic effect.
What is the difference between idiosyncratic reactions and allergic reactions to drugs?
3
, ✔✔ Idiosyncratic reactions are rare and unpredictable adverse effects that are not related to the
drug's known pharmacological action, while allergic reactions are immune-mediated responses to
the drug.
What does steady-state concentration refer to in drug administration?
✔✔ The point at which the rate of drug administration equals the rate of drug elimination,
resulting in constant drug levels in the body.
What is pharmacology?
✔✔ The study of drugs, including their origin, effects, and how they are used to treat diseases.
What is the difference between a drug's generic name and its brand name?
✔✔ The generic name is the official, non-proprietary name of the drug, while the brand name is
the trademarked name given by the manufacturer.
What is the primary purpose of a drug's pharmacokinetics?
✔✔ To study how the drug is absorbed, distributed, metabolized, and excreted in the body.
What does the term bioavailability refer to in pharmacology?
