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.
