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.
