Pharmacovigilance: Dawaon Ki Suraksha Ka Rakshak



🛡️ Pharmacovigilance: Dawaon Ki Suraksha Ka Rakshak 

🔍 Introduction – Pharmacovigilance Kya Hota Hai?

Aapne kabhi socha hai ki koi medicine lene ke baad agar kisi patient ko allergy, vomiting, ya serious reaction ho jaye, toh pharmaceutical company ya government ko kaise pata chalta hai?
Iska jawab hai – Pharmacovigilance.

Pharmacovigilance (PV) ek scientific process hai jiska main kaam hota hai:

✅ Medicine se hone wale side effects ko detect karna
✅ Unka analysis aur documentation karna
✅ Safety measures ko implement karna
✅ Public health ko ensure karna

Yeh ek global healthcare mission hai jiska motto hai – Medicines should not harm while healing.


🎯 Objectives of Pharmacovigilance

Pharmacovigilance ke kuch major objectives hote hain:

  1. Adverse Drug Reactions (ADR) ko identify karna

  2. Drug ke risk-benefit ratio ko monitor karna

  3. Signal detection aur pattern samajhna

  4. Data ko regulatory authorities tak pahuchana

  5. Preventive measures recommend karna

  6. Public awareness aur reporting culture promote karna


📜 History of Pharmacovigilance

Pharmacovigilance ka concept 1961 ke baad aaya, jab UK mein pregnant women ne Thalidomide naam ki medicine li, jisse thousands of babies deformities ke sath paida hue.

Is incident ke baad globally realization hua ki medicines ke side effects ko actively monitor karna zaruri hai.

Tab se leke aaj tak, PV ka role har ek country mein crucial ban gaya hai.





🏛️ Regulatory Framework for PV

🌐 International Bodies

Organization Role
WHO – Uppsala Monitoring Centre (UMC) Global pharmacovigilance database manage karta hai (VigiBase)
ICH (International Council for Harmonisation) PV ke international guidelines set karta hai
CIOMS (Council for International Organizations of Medical Sciences) PV reporting aur ethics framework define karta hai

🇮🇳 In India

Body Responsibility
CDSCO National drug regulatory authority
IPC (Indian Pharmacopoeia Commission) PvPI (Pharmacovigilance Programme of India) operate karta hai
NCC-PvPI (Ghaziabad) ADR data collect aur analyze karta hai

📊 Types of Adverse Drug Reactions (ADR)

Type Description
Type A (Augmented) Predictable, dose-related (e.g., drowsiness from antihistamines)
Type B (Bizarre) Unpredictable, rare (e.g., allergy from penicillin)
Type C (Chronic) Long-term use ke baad aane wale effects
Type D (Delayed) Time ke baad dikhnay wale effects (e.g., cancer)
Type E (End of use) Withdrawal effects
Type F (Failure) Drug ka expected result na milna

🔄 Process of Pharmacovigilance

Pharmacovigilance ka process ek continuous cycle hota hai:

1. Data Collection

  • Spontaneous reporting (doctors, pharmacists, patients)

  • Clinical trials

  • Literature review

  • Hospital data

  • Social media signals (modern trend)

2. Data Entry and Coding

  • WHO-ART aur MedDRA (Medical Dictionary for Regulatory Activities) ke coding systems use hote hain

  • Case narratives likhna

  • Seriousness aur outcome determine karna

3. Causality Assessment

  • WHO-UMC causality scale use hoti hai:

    • Certain

    • Probable

    • Possible

    • Unlikely

    • Unclassified

4. Signal Detection

Signal ka matlab hota hai kisi nayi adverse effect ka pattern identify karna.

Example: "XYZ injection se repeat ho raha liver failure" — Is pattern ko analyze karke signal banaya jata hai.

5. Regulatory Submission

  • PSUR (Periodic Safety Update Reports)

  • DSUR (Development Safety Update Report)

  • ICSRs (Individual Case Safety Reports)

6. Risk Management

  • Labeling changes

  • Drug recall

  • Safety alerts (Dear Doctor Letters)

  • Patient education initiatives


📦 Pharmacovigilance and Drug Lifecycle

Pharmacovigilance har stage mein active rehta hai:

Stage PV Role
Pre-clinical Animal toxicity monitoring
Clinical trials ADR documentation, SAE (Serious Adverse Event) reporting
Approval stage Risk-benefit analysis
Post-marketing Spontaneous ADR monitoring, recalls, safety updates

🧪 Pharmacovigilance During Clinical Trials

Clinical research ke dauraan PV ka role sabse zyada important hota hai:

  • All Serious Adverse Events (SAEs) 24 hours ke andar report kiye jaate hain

  • Ethics committees ko alert diya jata hai

  • Trial continue ya pause karne ka decision hota hai

🧠 Example: Agar Phase II trial mein 3 logon ko seizures aaye after taking test drug – toh immediately us data ko assess karke authority ko bataya jata hai.


💻 Software and Tools in PV

Modern pharmacovigilance mein kai tools aur systems use kiye jaate hain:

Software Use
Argus Safety Global safety database
ARISg Case management
VigiFlow WHO ka reporting tool
MedDRA Coding dictionary
EudraVigilance European drug monitoring tool

📑 Important Documents

Document Purpose
CIOMS Form International ICSR reporting
SAE Report Form Clinical trials mein serious events ko report karna
PSUR Periodic report of safety
DSUR Development safety update
Risk Management Plan Action plan for serious risks
