Pharmacokinetics Quiz - Drug Absorption Concepts

The study of how drugs move through the body.

The movement of a drug from the site of administration into the bloodstream.

The process of a drug spreading throughout the body.

The breakdown of drugs by the body.

The removal of drugs and their metabolites from the body.

Movement of drugs against a concentration gradient using energy.

Movement of drugs from high to low concentration without energy.

The physical form of a drug, impacting its absorption.

Method a drug is administered (e.g., oral, IV).

Thin layers that separate cells and tissues.

The process by which a drug moves from its site of administration into the bloodstream.

Aspirin, a weak acid, is nonionized in the acidic stomach, allowing good absorption.

In the alkaline small intestine, aspirin becomes ionized, reducing absorption.

The acidity (pH) of a location greatly affects a drug's ability to get absorbed.

Interactions between different drugs or food substances can alter drug absorption rates.

The portion of a drug that reaches the systemic circulation (blood) unchanged after taking it.

The process where a drug is metabolized by the liver after absorption, reducing the amount that reaches the systemic circulation.

The process of carrying drugs throughout the body.

The degree of blood flow to tissues directly correlates with the rate of drug distribution.

Certain tissues have a higher attraction for particular medications, influencing distribution.
