Study Notes

Pharmacovigilance and Adverse Drug Reactions

Pharmacovigilance (PV) is defined as the detection, assessment, understanding, and prevention of adverse effects or other possible drug-related problems.
PV is essential to prevent drug-related adverse effects in humans, ensure patient safety, and promote the rational use of drugs.

Importance of Pharmacovigilance

PV is well established in most industrialized countries, but its practice in low and middle-income countries is variable.
The World Health Organisation has developed a Pharmacovigilance Strategy to advance PV systems globally.

Minimum Requirements for Pharmacovigilance

A national pharmacovigilance centre with designated staff, stable funding, clear mandates, and collaboration with the WHO Programme for International Drug Monitoring.
A national spontaneous reporting system with a national individual case safety report (ICSR) form.
A national database or system for collating and managing ADR reports.
A national ADR or pharmacovigilance advisory committee for technical assistance on causality assessment, risk assessment, and risk management.
A clear communication strategy for routine communication and crisis communication.

Types of Pharmacovigilance

Drug Safety Surveillance
Drug Abuse and Adverse Effects Monitoring
Safety Monitoring of New Products

Purposes of Pharmacovigilance

To improve patient care and safety in relation to the use of medicines and all medical and paramedical interventions.
To improve public health and safety in relation to the use of medicines.

Self-Medication

Self-medication is the selection and use of medicines by individuals to treat self-recognized or self-diagnosed conditions or symptoms.
Under-medication can lead to serious health problems, including chronic pain, high blood pressure, dementia, and cognitive decline.

Implications of Drug Over-Prescription

Over-prescription can cause withdrawal symptoms, coma, or death.
Sudden stoppage of medication can lead to withdrawal symptoms such as nervous system hyperactivity and seizures.

Implications of Drug Under-Prescription

Under-prescription can cause a relapse or worsen the patient's condition.

Implications of Multiple Prescription

Taking multiple medications can result in drug interactions, leading to internal bleeding, confusion, light-headedness, and other adverse effects.

Adverse Drug Reactions (ADR)

ADRs are unintended and harmful responses that occur at normal doses of the drug used for prophylaxis, diagnosis, or treatment.
Classification of ADRs includes:
- Type A: Augmented pharmacological effect
- Type B: Bizarre or idiosyncratic reactions
- Type C: Chemical reactions
- Type D: Delivery related reactions
- Type E: End-of-treatment reactions
- Type F: Familial or genetic reactions
- Type G: Genetic toxicity
- Type H: Hypersensitivity reactions
- Type I: Unclassified reactions### Pharmacovigilance
Defined as the "science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other possible drug-related problems"
Aims to prevent drug-related adverse effects in humans, ensure patient safety, and promote the rational use of drugs

Types of Adverse Reactions

Type A: Augmented pharmacological effects (e.g. hypoglycemia due to insulin injection)
Type B: Bizarre adverse effects (e.g. anaphylaxis due to penicillins, acute hepatic necrosis due to halothane)
Type C: Chronic effects (e.g. craniofacial malformation due to phenytoin)
Type D: Delayed effects (e.g. alkylating agent use in the treatment of Hodgkin's second cancer)
Type E: End of treatment effects (e.g. angina with beta-adrenergic receptor, adrenocortical insufficiency after glucocorticoid withdrawal)

Drug Interactions

Occur when a patient's response to a drug is modified by food, nutritional supplements, formulation excipients, environmental factors, other drugs, or disease
Can be beneficial or harmful
May increase or decrease the effects of one or both drugs
Examples: coadministration of lopinavir and ritonavir to patients with HIV infection, therapeutic duplication (e.g. taking a benzodiazepine for anxiety and another benzodiazepine at bedtime for insomnia)

Functions of a National Pharmacovigilance System

Promote pharmacovigilance in the country
Collect and manage adverse drug reaction reports, medication errors, and suspected counterfeit/substandard drugs
Identify signals of medicine safety and undertake assessment of risk and options for risk management
Provide effective communication on aspects related to medicine safety

Minimum Requirements for a Functional National Pharmacovigilance System

A national pharmacovigilance centre with designated staff, stable basic funding, clear mandates, well-defined structures and roles
A national spontaneous reporting system with a national individual case safety report (ICSR) form
A national database or system for collating and managing ADR reports
A national ADR or pharmacovigilance advisory committee able to provide technical assistance

National Drug Formulary

Contains a list of medicines approved for prescription throughout the country
Includes key information on the composition, description, selection, prescribing, dispensing, and administration of drugs/medicines
Examples: United States Pharmacopia and National Formulary (USP-NF), British National Formulary, Nigeria EMDS

Self-Medication

Defined as the selection and use of medicines by individuals to treat self-recognized or self-diagnosed conditions or symptoms
A global phenomenon and potential contributor to antimicrobial resistance
Risks include incorrect self-diagnosis, delayed seeking of medical advice, severe adverse reactions, and incorrect administration or dosage

Importance of Patient Education and Counseling on the Use of Drugs

Patient education aims to train patients in the self-management of their chronic disease
Includes providing clear medication-related information to improve adherence
Counseling enhances patient understanding of their role in safe drug use### Medicines and their Classification
Adenosine and Digoxin are anti-arrhythmic medicines
Methyldopa and Esmolol are anti-hypertensive medicines

Over-prescription can cause withdrawal symptoms, coma, or death
Under-prescription can cause relapse or worsening of patient condition
Multiple drug prescription can result in drug interactions, leading to internal bleeding, confusion, and lightheadedness
