Study Notes
Clinical Pharmacology
- Encompasses all aspects of drug action in humans
- Focuses on evidence-based application
- Addresses treatment errors, adverse reactions, and economic aspects (pharmacoepidemiology, pharmacoeconomics)
Drug Development
- Complex and lengthy process
- Active substances derived from medicinal plants, microorganisms, animal tissues, and existing molecules modified
- Discovery begins with an idea/hypothesis, followed by substance design/synthesis, preclinical (in vitro/in vivo) and clinical studies, legal authorization for marketing, and post-marketing studies
- Involves three stages: discovery, development, and marketing
Discovery
- Selecting a drug action target (receptors, enzymes, transport proteins)
- Identifying and optimizing the key substance
- Pharmacological profiling of candidates based on various properties
- Typically takes 2-5 years
Development
- Includes preclinical and clinical studies
- Preclinical studies (1.5 years avg.): pharmacodynamics and pharmacokinetics research, experimental animals and tissue culture studies. Also include toxicological studies.
- Clinical Studies (5-7 years): 4 phases evaluating efficacy, side effects, and risks in healthy volunteers and patients
Phase I Studies
- Pharmacodynamic and pharmacokinetic studies
- Drug tolerability and side effects evaluated in healthy volunteers (20-100)
Phase II Studies
- Efficacy and dosage determined in smaller patient groups (100-200)
Phase III Studies
- Controlled clinical trials involving a large number of patients (1000-6000)
- Double-blind study design
- Evaluating drug safety
Phase IV Studies
- Post-marketing surveillance. Continuous monitoring of drug safety.
- Used to clarify issues from previous phases (comparing effects to other drugs, cost-effectiveness, patient compliance, quality of life, new indications), investigate interactions and application options (administration methods, dosage, treatment duration).
- Also evaluates drug efficacy in numerous patients, assessing toxicity and rare adverse effects.
- Includes a variety of specialized studies, including pharmacoepidemiology and clinical studies
- Evaluating the risk-benefit ratio
Marketing
- Compliance with regulations of the country where the drug is sold and distributed
- The pharmaceutical company that holds the license retains exclusive production and sales rights (patent) for a specific timeframe.
Toxicity Testing
- Crucial for demonstrating how a potential drug can cause in vitro or in vivo damage
- Long-lasting studies using high doses on many animals
- Several types of toxicity testing. Acute toxicity (LD50), repeated-dose studies
Rational Pharmacotherapy
- Tailoring treatment to individual patient needs, considering various diseases, medications, and patient factors
- Emphasize scientific research, practical applications (e.g. safety, efficacy, cost-effectiveness)
- Involves understanding the benefits and costs of treatments for a given patient.
- A physician must choose medications that best suit the patients needs, considering available resources and evidence
PharmacoVigilance
- Science and practice dedicated to detecting, assessing, understanding, and preventing adverse drug effects
- Key responsibilities include identifying new adverse reactions, identifying patient subgroups at risk, and continuously monitoring drug safety.
- Includes detailed evaluation of pharmacological properties that cause harm to the body.
- Ensuring that doctors, pharmacists, and healthcare workers are well-informed about potential risks
Drug Information Sources
- Textbooks, monographs, pharmacopoeias, drug registries, review articles, original research, manufacturer data, and electronic databases
