Nursing
The primary mechanism of action for typical non-steroidal anti-inflammatory drugs (NSAIDs).
Alpha-adrenergic blockade
Angiotensin-converting enzyme activation
Cyclooxygenase inhibition
Dopamine receptor agonism
The term for when a drug is used for a condition or in a manner not specified in the drug's approved labeling.
Off-label use
Drugs that produce a physiological effect opposite to that of an agonist, often by binding to the same receptor.
Inverse agonists
Beta-blockers primarily achieve their therapeutic effects by antagonizing which receptors?
Beta-adrenergic receptors
Which class of diuretic drugs primarily acts on the ascending limb of the loop of Henle to inhibit sodium and chloride reabsorption?
Loop diuretics
A prodrug is an inactive compound that is metabolized into an active drug in the body. Which of these is an example of a prodrug?
Codeine
The process by which the body chemically alters a drug, often to facilitate its excretion.
Drug metabolism
A common adverse effect of opioid analgesics that can lead to significant discomfort and often requires management.
Constipation
A drug that binds to a receptor but does not produce a direct cellular response, instead blocking the action of an agonist.
Antagonist
The term for the fraction of an administered dose of unchanged drug that reaches the systemic circulation.
Bioavailability
An agent that inhibits the growth of bacteria without necessarily killing them.
Bacteriostatic agent
A drug that binds to a receptor and produces a maximal biological response.
Full agonist
The process by which the amount of drug that reaches systemic circulation is reduced before reaching its site of action, typically in the liver.
First-pass metabolism
The primary receptor type that opioid analgesics like morphine bind to for their pain-relieving effects.
Mu-opioid receptors
Which of these adverse effects is commonly associated with angiotensin-converting enzyme (ACE) inhibitors?
Persistent dry cough
The phenomenon where the administration of two drugs simultaneously results in an effect greater than the sum of their individual effects.
Synergism
Selective Serotonin Reuptake Inhibitors (SSRIs) primarily exert their antidepressant effects by blocking the reuptake of which neurotransmitter?
Serotonin
The primary organ responsible for the excretion of most drugs and their metabolites from the body.
Kidney
The time it takes for the concentration of a drug in the body to decrease by half.
Half-life
The term describing a decreased response to a drug's effect over time, requiring larger doses to achieve the same effect.
Tolerance
The study of how genetic variations affect an individual's response to drugs.
Pharmacogenomics
The measure of the relative safety of a drug, defined as the ratio of the toxic dose to the effective dose.
Therapeutic index
Which cytochrome P450 enzyme is notably inhibited by grapefruit juice, leading to increased levels of certain drugs?
CYP3A4
The phase of drug development that involves testing in a small group of healthy volunteers to assess safety and pharmacokinetic profiles.
Phase I clinical trial
The theoretical volume into which a drug disperses in the body.
Volume of distribution
