Study Notes
Terminology in Pharmacology
- Therapeutic Use of Drugs: Refers to the specific applications of medications for treatment purposes.
- Harmful Effects: Describes adverse effects of drugs that may damage vital organs with long-term use, highlighting the potential risks related to continuous medication.
- Pharmacokinetics: The area of pharmacology that studies how drugs move through the body, including absorption, distribution, metabolism, and excretion.
Sources and Drug Approval
- Main Source of New Drugs: Natural products remain the primary source for the development of new pharmaceuticals, emphasizing the importance of natural compounds in drug design.
- Drug Approval Requirements: Drugs must pass rigorous testing to demonstrate safety and efficacy before being approved for human use, ensuring only reliable medications reach the market.
Drug Effects and Mechanisms
- Undesirable Drug Effects: These include effects categorized as adverse, which imply drug poisoning, illustrating the serious impact of certain pharmacological agents.
- Agonists: Drugs that bind to specific receptors in the body, resulting in a biological effect, playing a central role in pharmacodynamics.
- Antagonists: Medications that bind to receptors but do not activate them, blocking the action of agonists and impacting cellular functions.
Pharmacological Principles
- Time vs. Plasma Drug Concentration Curve: This relationship is depicted graphically and is critical in understanding the pharmacokinetic behavior of drugs over time.
- Dose-Response Relationship: A fundamental concept illustrating that the effect of a drug increases with the dose, highlighting the importance of determining appropriate dosing for therapeutic benefits.
