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.
