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.
