Study Notes
Definition of Pharmacology
- Pharmacology studies drugs and their interactions with living organisms.
- Etymology: "Pharmaco-" stems from the Greek "pharmakon," meaning remedy or poison.
- Key aspects include drug sources, chemical structure, administration, pharmacokinetics (absorption, distribution, metabolism, excretion), and pharmacodynamics (effects on body systems).
Importance of Pharmacology for Healthcare Professionals
- Understanding drug effects is crucial for nurses and health professionals.
- Responsibilities include administering medications, educating patients, assessing drug actions, minimizing side effects, and monitoring patient care plans.
Sources of Drugs
- Drugs originate from natural (plants, animals, inorganic compounds) and synthetic sources.
- Natural sources:
- Plants: Used historically, e.g., morphine (pain relief), codeine (cough suppression).
- Animals: Previously sourced proteins and hormones like insulin, now often synthesized for purity.
- Inorganic Compounds: Therapeutic salts such as aluminum, magnesium, and iron.
- Chemical Synthesis: Many drugs are created synthetically after identification of therapeutic compounds from nature.
Drug Naming Conventions
- Chemical Name: Reflects the drug's chemical structure.
- Generic Name: Also known as International Nonproprietary Name (INN); assigned by companies during approval applications.
- Trade Names: Names registered by pharmaceutical companies for marketing.
- Brand Name: The original trade name under which the drug was marketed.
Legal Aspects of Drug Use
- Drug regulation is managed by health authorities (e.g., FDA in the U.S., EMA in the EU).
- Drugs are categorized as:
- Prescription Drugs: Require a healthcare professional's prescription (e.g., anti-hypertensives).
- Over-the-Counter (OTC) Drugs: Purchased without a prescription for self-medication (e.g., mild analgesics).
- Controlled Drugs: High abuse potential, requiring secure prescriptions (e.g., narcotics).
Drug Use in Pregnancy
- Regulatory bodies classify drugs into categories indicating their potential teratogenic risk.
- Understanding these classifications is essential for safe drug administration during pregnancy.
Importance of Drug Information
- Continuous education on drugs is vital as therapeutic knowledge evolves.
- Access to reliable information is obtained through:
- Drug Labels: Include essential information like names, dosage forms, and special warnings.
- Package Inserts: Provide comprehensive details on pharmacology, therapeutic actions, dosages, warnings, and drug interactions.
- Drug Guides and Monographs: Contain extensive data on various drugs and their uses.
- Reference Books: Offer a variety of information within pharmacology and pharmacotherapy.
- Scientific Journals: Serve as updated sources for drug-related research and developments.
- Authentic Websites: Deliver reviewed and up-to-date pharmacological information.
