    Study Notes

    Pharmacology Overview

    • Pharmacology studies the effects of chemicals on biological systems.
    • Medical pharmacology focuses on using chemicals for disease prevention, diagnosis, and treatment in humans.
    • Key processes: absorption, metabolism, excretion; pivotal to understanding drug biodisposition.

    Drug Effects and Terminology

    • Pharmacokinetics: The movement of drugs within the body (absorption, distribution, metabolism, excretion).
    • Pharmacodynamics: The effects of drugs on the body, including mechanisms of action and therapeutic/toxic outcomes.
    • Transporters: Specialized proteins aiding drug, neurotransmitter, or molecule passage across membranes (e.g., Na+/K+ ATPase).

    High-Yield Terms

    • Placebo: An inactive medication resembling an active drug, used for comparison.
    • Single-blind study: Investigators know treatment allocation while subjects do not.
    • Double-blind study: Neither subjects nor investigators know treatment allocation; maintains study integrity.
    • IND (Investigational New Drug): Application for FDA permission to test new drugs on humans; requires prior animal data.
    • NDA (New Drug Application): Seeks FDA approval for drug marketing post-clinical trials.
    • Orphan drugs: Developed for rare diseases (affecting fewer than 200,000 people); incentivized by U.S. legislation.

    Drug Legislation Context

    • Significant drug regulation laws were enacted in the 20th century to ensure safety and efficacy.
    • Current U.S. laws incentivize the development of orphan drugs through tax relief and other benefits.

    Clinical Trials Phases

    • Phases 1, 2, and 3 involve progressive evaluation of drug safety and efficacy before NDA submission.
    • Positive control: A term describing a standard therapy used alongside placebo for comparative evaluation in trials.

    Special Characteristics of Drugs

    • Mutagenic effects alter inheritable traits; assessed through the Ames test.
    • Carcinogenic effects induce cancerous characteristics; teratogenic effects cause birth/developmental abnormalities.

    Study Recommendations

    • Reproduce drug overviews from memory for better retention.
    • Utilize a companion textbook, such as Basic & Clinical Pharmacology, to reinforce learning.
    • Investigate connections through Skill Keeper questions to integrate new and existing knowledge.
