Drug Information Sources (Izvori Informacija o Lekovima)

Vocabulary flashcards covering primary, secondary, and tertiary drug information sources, PubMed search techniques, systematic reviews, guidelines, and digital resources.

Primary Drug Information Sources

Information sources that present original research, new ideas, and/or opinions, including controlled clinical trials, cohort studies, case-control studies, and case reports.

Secondary Drug Information Sources

Information sources that index and retrieve primary literature, including bibliographic databases, systematic reviews, meta-analyses, and databases of systematic reviews.

Tertiary Drug Information Sources

Information sources that filter, summarize, and synthesize data from primary literature to provide quick access, including textbooks, handbooks, and drug databases.

Advantages and Disadvantages of Primary Sources

Advantages include comprehensive, highly specific, and current information; disadvantages include conclusions based on a single study and the requirement of specialized critical appraisal skills.

PubMed

The most well-known biomedical bibliographic database, maintained freely by the National Library of Medicine (Bethesda, USA), containing over 39 million records from around 5000 journals across 80+ countries.

Boolean Search Operators (AND, OR, NOT)

Connectors used in PubMed searches to combine multiple terms: AND requires all terms to be present, OR requires at least one term to be present, and NOT excludes specified terms.

Search Truncation Symbol (*) in PubMed

A symbol appended to a word stem (e.g., terap*) to retrieve all word variations containing that root, such as terapija, terapijski, or terapeutski.

Parentheses in Database Searching

Used to group search terms and direct search logic, such as fluoksetin AND (anoreksija nervoza OR bulimia nervoza).

Systematic Reviews

Literature reviews on a specific topic where authors collect, analyze, critically evaluate, and integrate results from multiple independent published and unpublished studies.

Meta-Analysis

A quantitative systematic review that uses statistical methods to combine and integrate results from multiple independent studies to derive conclusions.

Cochrane Database of Systematic Reviews (CDSR)

The largest and most prominent database of systematic reviews, prepared by international expert working groups following strict methodological criteria.

Clinical Practice Guidelines (Vodiči dobre kliničke prakse)

Recommendations for prevention, diagnosis, and therapy of specific morbidities, expressed as concise statements with levels of evidence (A, B, C) and recommendation grades (I, II, III).

Level A, Grade I Clinical Recommendation

The highest rating in clinical practice guidelines, signifying strong evidence of treatment benefit.

Summary of Product Characteristics (SmPC / Sažetak karakteristika leka)

An officially approved regulatory document with a standardized structure providing essential qualitative, quantitative, clinical, and pharmacological data for a marketed drug.

Online Drug Databases (Lexicomp®, Clinical Pharmacology®, Epocrates®)

Tertiary resources available online or via mobile apps that provide updated information on drug dosing, contraindications, adverse reactions, and drug interactions.

Specialized Drug Information Handbooks

Reference books focused on specific drug aspects, such as Stockley's Drug Interactions, ASHP Handbook of Injectable Drugs, and Briggs Drugs in Pregnancy and Lactation.

Orphanet

An online database providing comprehensive information on rare diseases and orphan drugs (https://www.orpha.net).

Artificial Intelligence (AI) in Drug Information

Tools (e.g., ChatGPT, Perplexity AI, Claude, Copilot, Gemini) that offer rapid access to summarized data, but carry risks of inaccuracy, hallucinated references, and non-reproducibility.

Rule of Two Sources for Practice Questions

The principle that for most daily practice questions answered using tertiary sources, information should be verified in at least $2$ independent sources.
