Pharmaceutical Supply Chain

• Manufacturing sites? (API, finished goods, contract manufacturing)
• Distribution network? (direct, wholesale, specialty distributors)
• Cold chain capabilities?
• Geographic footprint? (local, regional, global)
• 3PL partnerships?

Pharmaceutical Supply Chain Framework

Value Chain Structure

Pharmaceutical Manufacturing & Distribution:

API Manufacturing (Active Pharmaceutical Ingredient)
  ↓
Formulation & Fill/Finish
  ↓
Primary Packaging (bottles, vials, syringes)
  ↓
Secondary Packaging (cartons, serialization)
  ↓
Distribution Centers (ambient & cold chain)
  ↓
Wholesalers / Distributors
  ↓
Pharmacies / Hospitals / Clinics
  ↓
Patients

Key Regulatory Frameworks:

• GMP (Good Manufacturing Practices): Manufacturing quality standards
• GDP (Good Distribution Practices): Distribution and storage requirements
• GCP (Good Clinical Practices): Clinical trial standards
• DSCSA (Drug Supply Chain Security Act): US track-and-trace
• EU FMD (Falsified Medicines Directive): European serialization
• ICH (International Council for Harmonisation): Global standards
