Study Notes
Pharmacovigilance History
- Thalidomide tragedy: 10,000 cases of congenital malformation (phocomelia) due to its use as a sedative and in pregnancy for morning sickness
Pharmacovigilance (PV)
- Definition: "The science and activities relating to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems"
- Main aims:
- Detect adverse drug effects and other drug-related problems
- Assess and evaluate adverse effects (severity, frequency, etc.)
- Identify and understand predisposing risk factors
- Prevent adverse effects and minimize risk
Cycle of Pharmacovigilance
- Safety communication
- Signal investigation
- Signal detection
- Risk-benefit minimization evaluation
- Signal: Reported information on a possible causal relationship between an adverse event and a drug
Key Features of Medications
- Safety
- Efficacy
- Quality
Scope of Pharmacovigilance
- Adverse drug effects
- Medication errors
- Drug interactions
- Lack of efficacy
- Antibiotic resistance
- Drug misuse and abuse
- Products covered: conventional medicines, herbal medicines, biologicals and biosimilars, blood products, vaccines, medical devices
Pharmacovigilance Intercountry & Interbrand Variations
- Need for pharmacovigilance due to health, economic, and humanitarian concerns
- Variations in:
- Population characteristics (genetics, ethnicity, etc.)
- Medications use culture
- Quality of pharmaceutical production
- Sources of APIs, excipients, manufacturing lines, and supply chain
- Quality of pharmaceutical production
Drug Repositioning/Repurposing
- Drug development
Clinical Development of Medicines
- Continuous safety monitoring throughout drug lifecycle
- Limitations of premarketing clinical studies:
- Limited patient number
- Limited duration of drug exposure
- Restricted patient population
- Importance of pharmacovigilance (post-marketing surveillance)
- Identify previously unknown drug-related problems
- Assess drug safety in special populations
- Identify different types of potential drug interactions
- Identify predisposing risk factors for adverse drug effects
