Pharmacology First Trimester Term

Study Notes

Pharmacology Overview

Focuses on pharmacodynamics, pharmacokinetics, and therapeutic uses of drugs in health promotion and disease management.
Nursing process is integral for safe drug administration, medication monitoring, and client education.

Fundamental Concepts of Pharmacology

Drug Definition: Substances modifying bodily functions, effects can be local or systemic.
Drug Classification: Identifies drugs based on their effects and purposes.
Drug Standards: Regulates the quality and safety of medications.
Drug Information: Essential knowledge regarding drug use, including indications and side effects.

Branches of Pharmacology

Pharmacodynamics: Study of drug mechanisms producing biochemical or physiological changes.
Pharmacokinetics: Explores how drugs are absorbed, distributed, metabolized, and excreted in the body.
Pharmacotherapeutics: Focuses on drug use in disease prevention and treatment.
Clinical Pharmacology: Evaluates drugs in human use, ensuring safety and efficacy.
Pharmacogenetics: Investigates genetic variations affecting drug response.
Pharmacovigilance: Involves monitoring drug safety and preventing adverse effects.
Pharmacoeconomics: Examines the economic aspects of drug use and management.
Toxicology: Studies adverse drug effects.

Pharmacodynamics

Involves interactions at the cellular level (binding to regulatory molecules).
Evaluates how drugs influence physiological processes.

Pharmacokinetics

Absorption: Process of drug intake into the body.
Distribution: Movement into tissues for potential excretion.
Metabolism: Transformation of a drug into different chemical forms.
Excretion: Removal of drugs from the body.
Addresses drug onset, concentration, and duration of action.

Drug Sources

Traditionally derived from:
- Plants
- Animals
- Minerals
Synthetic Sources involve:
- Natural mimicking
- Natural modification
- Laboratory synthesis

Names of Drugs

Chemical Name: Describes the chemical structure of the drug.
Generic Name: Universal name indicating the drug's pharmacological category.
Brand Name: Proprietary name used to market the drug.

Learning Outcomes

Understand the origin, definition, and branches of pharmacology.
Define drugs and classify them accordingly.
Identify drug standards and necessary drug information.
Differentiate between chemical, generic, official, and brand names of medications.
Explain drug processes (absorption, distribution, metabolism, excretion).
