Study Notes
Introduction to Pharmacology
- Pharmacology is the study of the effects of drugs and chemicals on living organisms.
- A drug is any chemical substance that affects biological systems.
- Pharmacology emerged from an understanding of magic potions and plant-derived remedies/poisons.
- Experimental pharmacology and organic chemistry have played a key role in its development.
Current Pharmacology
- Current pharmacology can be subdivided into three areas: Drug, Organism, and Therapeutic Applications.
- Drug focuses on aspects like pharmacognosy, chemical pharmacology, pharmacotechnics, and ethnopharmacology.
- Organism investigates pharmacokinetics, pharmacodynamics, pharmacometry, pharmacogenomics, and chronopharmacology.
- Therapeutic Applications include clinical pharmacology, pharmacotherapy, toxicology, pharmacoepidemiology, pharmacoeconomics, and gene therapy.
Aims of Pharmacology
- The primary goal of pharmacology is the rational use of drugs: ensuring patients receive appropriate medication at the correct dose, for the proper duration, and at the lowest possible cost.
- This includes achieving a balance between benefits and risks, considering adverse effects, costs, and potential administration problems.
- Another aim is to facilitate a rational therapeutic process by understanding how drugs penetrate the patient (formulations, routes of administration, therapeutic compliance), reach their site of action (pharmacokinetics), and produce the expected pharmacological effect (pharmacodynamics).
- Clinical pharmacology identifies factors that alter drug response, communicates their importance, individualizes treatments, and monitors response to adjust treatment if necessary.
- A final key aim is reviewing pharmacological treatment to optimize its effectiveness, minimize adverse reactions, detect interactions and duplications, improve compliance, enhance efficiency, and differentiate between adverse drug reactions and new pathologies.
Drug Nomenclature
- Drugs are typically classified based on therapeutic utility, mechanism of action, or an anatomical therapeutic chemical classification (ATC) system.
- The ATC system organizes drugs hierarchically: first level (main anatomical group), second level (main therapeutic group), third level (therapeutic/pharmacological subgroup), fourth level (chemical/therapeutic/pharmacological subgroup), and fifth level (chemical).
Types of Pharmacological treatments
- Different types of pharmacological treatments include:
- Aetiological/curative treatment: Targets the cause of the pathological mechanism.
- Pathogenic/corrective treatment: Addresses the pathological mechanism without targeting the cause.
- Prophylactic treatment: Preemptive prevention of disease.
- Suppressive treatment: Temporarily alleviates disease symptoms.
- Functional/symptomatic treatment: Relieves or suppresses disease symptoms.
Medical Prescription
- A medical prescription is a legally required document used by medical professionals to authorize pharmacists to dispense specific prescription drugs to patients.
- It is a formal communication between a healthcare professional and a pharmacist ensuring appropriate drug use.
