Study Notes
Introduction to Pharmacovigilance
- Pharmacovigilance (PV) is essential for ensuring drug safety post-market.
- It starts with drug discovery and continues through phases of clinical research and FDA review.
- Key phases include preclinical research, clinical trials (Phase 1, 2, and 3), and post-marketing surveillance.
PV Process
- Drug development involves drug discovery, testing for safety and efficacy, regulatory review, and continuous monitoring after market release.
- The FDA evaluates submitted data, ensuring safety before drugs are approved for public use.
Adverse Drug Reaction (ADR) Assessment
- The Naranjo Scale is a tool used to assess ADR causality, consisting of 10 questions with different scoring.
- Scores range from -4 to +13; classifications include:
- Definite: Score of 9 or higher
- Probable: Score between 5 and 8
- Possible: Score between 1 and 4
- Doubtful: Score of 0 or less
Key Guidelines in Pharmacovigilance
- ICH E2A established standards for clinical safety data management.
- ICH E2B focuses on the electronic transmission of individual case safety reports.
- EU Good Pharmacovigilance Practices (GVP) provide comprehensive guidance for monitoring drug safety in Europe.
- FDA Title 21 outlines requirements for post-marketing reporting in the U.S.
Clinical Trials Overview
- Clinical trials compare a treatment to a placebo or standard treatment to assess safety and efficacy.
- Investigational drug effects and potential adverse reactions are key focuses during trials.
- Studies can be single-blind (participant unaware) or double-blind (both participant and investigator unaware).
Pharmacovigilance Programme of India (PvPI)
- Launched by the Central Drugs Standard Control Organization (CDSCO) under the Ministry of Health.
- Coordinated by the Indian Pharmacopoeia Commission with guidelines for regulatory interventions from a Steering Committee.
Handling Fraudulent Reports
- Verify and consult with peers before concluding on report accuracy.
- Address discrepancies professionally to maintain pharmacovigilance integrity and ensure patient safety.
Social and Risk Factors in ADRs
- Factors influencing ADRs include alcohol use, smoking, obesity, diet, age, and organ impairments (hepatic and renal).
- Identification of risk factors is crucial for accurate causality assessments in ADR cases.
Continuous Monitoring
- Ongoing surveillance is vital for maintaining drug efficacy and safety in the broader clinical population.
- Regular updates on product information and communication of risks is essential for healthcare providers and patients.
