Flashcards

Pharmacokinetics

The study of how drugs move into, around, and out of the body, including absorption, distribution, metabolism, and excretion.

Absorption

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

Distribution

The process of a drug moving from the blood stream to the tissues and organs.

Metabolism

The process of converting a drug into a different form by the body.

Study Notes

Pharmacokinetics

  • Pharmacokinetics is the study of how the body absorbs, distributes, metabolizes, and eliminates drugs.
  • This field analyzes the time course of drug concentration in the body.
  • The logarithm of a negative number is undefined in pharmacokinetics and mathematics in general.

ADME

  • ADME stands for Absorption, Distribution, Metabolism, and Excretion.
  • These four processes describe the journey of a drug through the body.

Logarithm of 1

  • The logarithm of 1 is 0 (log 1 = 0).

Key Terms

  • Absorption refers to the process by which the drug enters the bloodstream from its site of administration.
  • Distribution describes the process by which the drug travels from the bloodstream to different tissues and organs.
  • Metabolism involves the breakdown of the drug into metabolites, which can be more easily excreted.
  • Excretion is the process by which the drug and its metabolites are eliminated from the body.
