    Study Notes

    Drug Basics

    • A drug is any substance that causes a change in a person's physical or psychological state.
    • A medicine is a drug used to cure, prevent, or treat illness with three key qualities: effectiveness, safety, and minor or minimal side effects.

    Medication Administration

    • A prescription is a written order from a doctor for a specific medicine and amount.
    • Over-the-counter (OTC) medicines can be purchased without a prescription and are sold on store and pharmacy shelves.

    How Drugs Enter the Body

    • Implantable pump (e.g., insulin pump)
    • Inhalation (through blood vessels in the lungs)
    • Injection (through a needle)
    • Transdermal (through a patch)
    • Ingestion (swallowed)
    • Topical (applied and absorbed through the skin, e.g., medicated cream)

    Drug Effects and Consequences

    • Tolerance: cells of the body adapt, requiring more of the drug to feel original effects.
    • Dependence: drug must be present in the system at all times for daily functioning, leading to withdrawal symptoms upon cessation.
    • Addiction: a condition where the brain's reward system drives continued substance use, leading to loss of control and physical and psychological dependence.
    • Drug Abuse: using a drug for no medical reason.
    • Drug Misuse: medically using a drug but taking the wrong amount, skipping days, or using the wrong method of intake.
