drug classifications
Classified by effect on body system; chemical composition; clinical indication or therapeutic action (2 primary classifications)
pharmaceutical class
Refers to the mechanism of action (MOA), physiologic effect (PE), and chemical structure (CS) of the drug (attacks bacteria by…)
therapeutic class
Refers to the clinical indication (why you’re using it) for the drug or therapeutic action (e.g., analgesic, antibiotic, or antihypertensive).
pharmacokinetics
effect of body on drug
absorption
drug moves from site of administration into bloodstream
distribution
drug transported in body fluid (typically bloodstream) to site of action: tissue/organ
metabolism
chemical conversion of drug in the body into water. Soluble compound of metabolites that can be excreted
excretion
drug molecules removed from site of action and eliminated from body
Factors Affecting Absorption of Medications
Route of administration
Lipid solubility
pH
Blood flow
Local conditions at the site of administration
Drug dosage
pharmacodynamics
the process by which drugs alter cell physiology and affect the body.
(how the drug affects the body)
Drugs turn on, turn off, promote, or block responses that are part of the body’s processes.
Drug–receptor interaction occurs when the drug interacts with one or more cellular structures to alter cell function.
Drugs may also combine with other molecules in the body to achieve their effect.
Other drugs act on the cell membrane or alter the cellular environment to achieve their effect.
drug-receptor interaction
occurs when the drug interacts with one or more cellular structures to alter cell function
palliative effects
treats symptoms of disease but not disease itself
supportive effects
supporting integrity of body function until another drug is effective
substitute effects
replace body fluids or chemical chemotherapeutic effects-destroy disease-producing organisms
restorative effects
restore to optimal health
examples adverse drug effects
Allergic effects: anaphylactic reaction
Drug tolerance
Toxic effect
Idiosyncratic effect
Drug interactions: antagonistic and synergistic effects
