Study Notes

Drug Nomenclature and Classification

Generic names are assigned by the U.S. Adopted Names Council, an organization supported by the U.S. Pharmacopeial Convention, the American Medical Association, and the American Pharmacists Association.
The official name, usually the generic name, is the FDA-listed name for drugs in the United States.
Brand names are trademarked (®), restricted to the manufacturer, and designed for better memorability. Most drugs are marketed under brand names.
Orphan drugs treat rare, life-threatening diseases, often lacking market incentive for development.

Drug Classification by Pharmacological Effect

Drugs are broadly classified based on their effects on the body.
Examples include analgesics (pain relief), antibiotics (infection treatment), and antiseptics (germ killing).

Potency vs. Efficacy

Potency refers to the drug concentration needed for a defined effect.
Efficacy measures a drug's therapeutic effectiveness in humans.

Pharmacokinetics

Pharmacokinetics studies the body's impact on drugs, including liberation, absorption, distribution, metabolism, and excretion (LADME). LADME details how the drug is processed by the body.

Drug Metabolism and Excretion

Drug metabolism is the body's biotransformation of drugs for easier elimination.
Excretion is the elimination of drugs from the body.

Drug Types

Drugs are categorized as prescription (needing a healthcare professional's order) or nonprescription/over-the-counter (OTC).
Illegal drugs are used non-therapeutically and lack FDA approval.

Drug Standardization

Drug products from different manufacturers or batches must have uniform purity and potency.

Clinical Trials

Preclinical trials test drugs in animals for safety data before human trials.
Phase I studies involve a small number of healthy human subjects; patients may be used if safety in healthy people is unlikely.
Phase IV studies are post-marketing surveillance, encompassing safety monitoring and ongoing support.

FDA Pregnancy Categories

Category A: No risk to fetus demonstrated in controlled studies.
Category B: No fetal risk in animal studies or confirmed in controlled human studies.
Category C: Adverse effects in animal studies, but human data unavailable; benefits may outweigh risks for pregnant women.
Category D: Fetal risk demonstrated, but benefits may outweigh risks in specific situations.
Category X: Teratogenic effects; contraindicated in pregnancy.

Factors Influencing Drug Response

Weight, age, gender, physiological factors (acid-base balance, hydration, electrolytes), pathological factors (GI disorders, low BP), genetic factors, immunological factors (allergies), psychological factors (attitude), environmental factors (temperature, sunlight), tolerance, cumulation, and drug interactions.
