(24 cards)
What is pharmacology?
The study of drugs and their interactions with living organisms.
True or False: Pharmacokinetics refers to how the body affects a drug.
True
What is the difference between pharmacokinetics and pharmacodynamics?
Pharmacokinetics deals with drug absorption, distribution, metabolism, and excretion, while pharmacodynamics focuses on the drug’s effects on the body.
What is a drug receptor?
A target molecule in the body that a drug binds to, resulting in a biological response.
Fill in the blank: The study of drug interactions with living organisms is known as ________.

What is a drug’s half-life?
The time it takes for the concentration of a drug in the body to decrease by half.
True or False: Drugs can have both therapeutic and adverse effects.
True
What is the placebo effect?
A phenomenon where a patient’s symptoms improve after receiving a placebo, an inactive substance.
What is drug tolerance?
A reduced response to a drug after repeated use.
Fill in the blank: Pharmacokinetics deals with drug ________, distribution, metabolism, and excretion.
absorption
What is a drug’s bioavailability?
The fraction of the administered drug that reaches systemic circulation.
True or False: Drug metabolism primarily occurs in the kidneys.
False
What is a drug’s mechanism of action?
The specific way in which a drug produces its effects in the body.
Fill in the blank: Pharmacodynamics focuses on the drug’s effects on the ________.

What is a drug’s therapeutic index?
The ratio of a drug’s toxic dose to its therapeutic dose.
True or False: Drug interactions can occur when two or more drugs are taken together.
True
What is the difference between a generic drug and a brand-name drug?
Generic drugs are typically cheaper versions of brand-name drugs and contain the same active ingredients.
What is drug pharmacokinetics?

What is a drug’s side effect?
An unintended effect of a drug that is not related to its intended therapeutic action.
True or False: Drug interactions can enhance or reduce the effects of a drug.
True
What is a drug’s pharmacodynamics?
The study of a drug’s effects on the body and the mechanisms of drug action.
What is drug metabolism?
The process by which the body breaks down and transforms drugs into metabolites.
