Journey 2 — Drug Directory

From EDA Registry to the Doctor's Prescription Pad

Personas

EDA Admin — Egyptian Drug Authority data manager, responsible for the national formulary
Dr. Mohamed Khalil — GP (HPR-12345-GP), searching for the right drug
Pharmacist Amir Saad — PHR-98765, at El-Ezaby Pharmacy (FAC-CAI-00445)

Today Without NDP

In Egypt's current system:

• Drugs are prescribed by brand name only (e.g., "Augmentin" — never "Amoxicillin/Clavulanate")
• No price transparency for patients at point of prescription
• No controlled-substance flag visible to the prescriber
• Pharmacist substitutes brand with generic based on memory / availability — no system record
• Drug recalls are announced on social media or via fax to pharmacies
• No real-time shortage alerts

---

The Medicine Directory's Role

The Medicine Directory is the single source of truth for all medications in Egypt. It is:

• Maintained by the Egyptian Drug Authority (EDA)
• The only approved drug list for NDP prescriptions
• The source for drug interaction data used by CDSS
• Synchronized with UHIS for insurance coverage and pricing

Sub-Journey A: EDA Drug Import Pipeline

How new drugs enter the system

The EDA maintains the master drug registry. Drugs enter the Medicine Directory through three mechanisms:

1. New Drug Registration (Batch)

When a new drug is approved by the EDA:

2. Real-Time Drug Update

When EDA updates a price or changes a drug's status:

PATCH /api/v1/medicines/EDA-MED-00456
{
  "retailPrice": 145.50,
  "uhisPrice": 87.30,
  "status": "ACTIVE"
}

3. Drug Recall Alert

When EDA issues a product recall (e.g., contaminated batch):

Sub-Journey B: Doctor Drug Search

Real Scenario: Dr. Mohamed searches for an antibiotic

Dr. Mohamed is at his desk. His patient has a sinus infection and needs an antibiotic. He types "Augmentin" in the prescription interface.

Search by INN (International Nonproprietary Name)

If Dr. Mohamed types "Amoxicillin" instead:

Results for "Amoxicillin":
────────────────────────────────────────
Amoxicillin 500mg Cap       (6 brands) → EDA-MED-00456
Amoxicillin 250mg/5ml Syrup (4 brands) → EDA-MED-00457
Amoxicillin/Clavulanate     (8 brands) → EDA-MED-00123
Amoxicillin 1g Tab          (3 brands) → EDA-MED-00458

The system encourages INN prescribing — but allows brand selection for patient familiarity.

Sub-Journey C: Generic Substitution Flow

Scenario: Pharmacist Amir finds the brand out of stock

Fatima comes to El-Ezaby Pharmacy (FAC-CAI-00445) with prescription RX-20260503A1B2C3. El-Ezaby doesn't have Augmentin 875mg in stock, but has the generic equivalent.

Substitution Rules

• substitutionAllowed: true on the prescription → pharmacist can substitute with bioequivalent
• substitutionAllowed: false → pharmacist must contact prescriber before substituting
• All substitutions are logged in the audit trail with pharmacist ID and reason

Sub-Journey D: Drug Information Panel

When a doctor selects a drug, they see a comprehensive information panel. This is what makes NDP different from writing on paper:
