Znajdź Lek

The Problem

Hospital doctors face a daily challenge: when interviewing patients about their medications, patients usually know only the brand names of drugs, not the active ingredients — which is what doctors actually need for clinical decisions.

This might sound trivial, but patients often take 20 or more medications. Manually looking up each drug’s active ingredient is incredibly time-consuming and interrupts the flow of patient care.

The Solution

I built Znajdź Lek (“Find Medicine” in Polish) — a fast, practical tool that helps doctors:

1. Search drugs by brand name — instantly get the active ingredient
2. Search by active ingredient — find all brand names containing it
3. Find alternatives — discover substitutes and drugs with the same composition
4. Bulk search from notes — paste messy clinical notes and search multiple drugs at once
5. Clean dosage information — automatically strip dosage formats like “1x1 tabl.”, “2x/d”, “co 6h” from pasted notes
6. View detailed drug information — manufacturer, links to patient leaflet, product characteristics
7. Check reimbursement status — find out if a drug is reimbursed, or which alternatives are

Key Features

Single & Bulk Search

Doctors can quickly search for individual drugs or paste entire medication lists from patient notes. The system intelligently parses messy input.

Smart Note Cleaning

Clinical notes often contain dosage information mixed with drug names. The cleaning feature automatically removes formats like:

• “1x1 tabl.”
• “3x/d.”
• “4x1tabl. co 6h”
• And many more variations

Comprehensive Drug Details

For each drug, you can access:

• Active ingredients (the most important info for doctors)
• Manufacturer information
• Direct links to patient information leaflet (PIL)
• Summary of product characteristics (SmPC)
• Reimbursement status and conditions

Finding Alternatives

Search results show similar drugs — both generic substitutes and medications with the same composition — helping doctors find alternatives when needed.

Data Sources

The database combines data from official Polish government sources:

• Register of Medicinal Products — the official registry maintained by the Office for Registration of Medicinal Products
• Ministry of Health Reimbursement Announcements — official list of reimbursed medicines

Both datasets were merged into a single, searchable database.

Built in 4 Hours with AI

The entire project — from concept to deployment — took approximately 4 hours thanks to AI-assisted development with Google Antigravity.

This demonstrates the power of modern AI tools for rapid prototyping and building practical applications that solve real-world problems.
