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.
