    Study Notes

    Drug Classification and Terminology

    • An agonist is a drug that binds to a receptor and stimulates its function.
    • Drug classification does not use the source of origin as a criterion.
    • Anticoagulants are classified by their therapeutic action.

    Prescription Requirements

    • Prescriptions must include patient information except for the patient's social security number.
    • Orders for drugs needed as required are termed PRN.
    • "SOS" on a prescription indicates once if necessary.
    • Dosing frequency is indicated as q4h for "every 4 hours" and tid for "three times a day".

    Drug Forms and Administration

    • Gas form of drug preparation acts more quickly than solids or liquids.
    • An ointment is abbreviated as Ung.
    • Oral administration is denoted as PO, while any route other than oral is termed parenterally.

    Pharmacokinetics

    • Pharmacokinetics involves absorption, distribution, metabolism, and excretion of drugs.
    • Drug distribution is primarily handled by the circulatory system.
    • The onset of action refers to the time between drug administration and the first effects.
    • The liver is the site for drug metabolism or biotransformation.
    • Kidneys are responsible for the excretion of most drugs.

    Drug Interaction and Effects

    • An antagonist blocks receptor sites, inhibiting responses.
    • A drug that enhances another's effect is called a synergist.
    • Side effects are expected but unintended drug actions.
    • Idiosyncratic effects like malignant hyperthermia are unique, often severe reactions to certain drugs.

    Drug Abbreviations

    • BID stands for twice a day, while NPO means nothing by mouth.
    • The amount of unbound drug molecules that can cause effects is termed bioavailability.

    Regulation and Legislation

    • The Pure Food and Drug Act of 1906 established drug quality and labeling standards.
    • The Controlled Substance Act was passed in 1970 and enforced by the DEA (Drug Enforcement Administration).
    • State practice acts govern the ordering, dispensing, and administering of medications.

    Clinical Trials and Resources

    • In the clinical pharmacology phase, drugs are tested on healthy volunteers.
    • The PDR (Physicians' Desk Reference) is the most widely used pharmacology resource.
