Chapter 17: Pharmacology

Substance in which a drug is transported

• drug

• drug vehicle

• postency

• efficacy

the study of drugs and their origin, nature, properties, and effects on living organisms

• pharmacology

• pharmacokinetics

• bioavailability

• biotransformation

Bioequivalent drugs:

• drugs that have similar biological effects

• when the amount of drug taken is equal to the amount that is excreted

• dose of a drug required to produce a desired effect

• volume of plasma in which the drug is dissolved

Steady-state:

• drugs that have similar biological effects

• when the amount of drug taken is equal to the amount that is excreted

• dose of a drug required to produce a desired effect

• volume of plasma in which the drug is dissolved

Potency:

• drugs that have similar biological effects

• when the amount of drug taken is equal to the amount that is excreted

• dose of a drug required to produce a desired effect

• volume of plasma in which the drug is dissolved

Volume of distribution:

• drugs that have similar biological effects

• when the amount of drug taken is equal to the amount that is excreted

• dose of a drug required to produce a desired effect

• volume of plasma in which the drug is dissolved

Half-life:

• rate at which the drug disappears form the body thorugh metabolism, excretion, or both

• changing a drug into a water soluble compound that can be excreted

• how completely a particular drug is absorbed by the system

• chemical agent used in the prevention, tx, and dx of a disease

Biotransformation:

• rate at which the drug disappears form the body thorugh metabolism, excretion, or both

• changing a drug into a water soluble compound that can be excreted

• how completely a particular drug is absorbed by the system

• chemical agent used in the prevention, tx, and dx of a disease

Bioavailability

• rate at which the drug disappears form the body thorugh metabolism, excretion, or both

• changing a drug into a water soluble compound that can be excreted

• how completely a particular drug is absorbed by the system

• chemical agent used in the prevention, tx, and dx of a disease
