PharmaGEN

🧬 PharmaGEN is a production-ready multilingual medical assistant and hypothetical drug concept generator powered by Google's Gemini AI. It allows users to describe their symptoms and allergies in their preferred language, then generates a conceptual diagnosis and hypothetical drug treatment.

✨ Features

• Multilingual Support: Communicate in 20+ languages including English, Hindi, Spanish, German, French, and more
• AI-Powered Diagnosis: Analyze symptoms to generate conceptual medical diagnoses
• Hypothetical Drug Generation: Create theoretical new drug concepts based on the diagnosis
• PDF Report Generation: Download a formatted medical report in your preferred language
• Production-Ready: Rate limiting, caching, error handling, and logging
• Responsive UI: Modern, user-friendly interface with real-time translation
• Docker Support: Easy deployment with Docker and Docker Compose

🐍 Python Version

Required (pyproject): Python 3.10+ — Recommended: Python 3.11.x

• Performance: 10-60% faster than Python 3.10
• Stability: Production-ready with long-term support until October 2027
• Compatibility: Full support for all dependencies
• Minimum: Python 3.10 (project metadata enforces ^3.10)

⚠️ Important Disclaimer

This application is for informational and conceptual purposes only.

• AI-Generated Diagnosis: The diagnosis provided is AI-generated and may not be accurate. Always consult a qualified medical professional for any health concerns.
• Hypothetical Drug Concepts: The drug compounds suggested are NEW, HYPOTHETICAL CONCEPTS generated by AI. They are not real, tested, safe, or approved medications.
• Safety Notes: Allergy and side effect notes are theoretical AI assessments. They are not a substitute for professional medical advice.

🚀 Quick Start

Pick the workflow that matches your toolchain. All options share the same environment steps for configuring the Gemini API key.

Option A: ⚡ uv (Fastest install, works everywhere)

# 1. Make sure you're inside the project folder
cd /path/to/PharmaGEN

# 2. (Optional) Install/manage the Python runtime
uv python install 3.11

# 3. Create an isolated .venv managed by uv (safe for other projects)
uv venv --python 3.11 .venv               # reuse existing env
# If prompted about an existing .venv, rerun: uv venv --clear
.venv\Scripts\activate
# 4. Install requirements into that .venv
uv pip install -r requirements.txt

# 5. Prevent PyFPDF/fpdf2 namespace conflicts (safe to run even if PyFPDF isn't installed)
uv pip uninstall -y pyfpdf   # ignore message if package isn't installed

# 6. Copy the environment template and add your Gemini key
copy example.env .env        # Windows
cp example.env .env          # macOS / Linux

# 7. Run the production build using the new .venv
uv run pharmagen             # or: uv run python app_production.py

Option B: 🪄 Poetry

cd /path/to/PharmaGEN
poetry env use 3.11
poetry install               # installs from poetry.lock

copy example.env .env        # Windows
cp example.env .env          # macOS / Linux

poetry run pharmagen         # or: poetry run python app_production.py

Option C: 🐍 Pip / Conda (legacy fallback)

# Create + activate an environment with Python ≥3.10 (3.11 preferred)
python -m venv .venv         # or: conda create -n pharmagen python=3.11 -y
.venv\Scripts\activate       # Windows
source .venv/bin/activate    # macOS / Linux / WSL

pip install -r requirements.txt
copy example.env .env        # Windows
cp example.env .env          # macOS / Linux

python app_production.py

Option D: 🐳 Docker

docker-compose up -d
# Access at http://localhost:7860

📦 Dependency Management Cheat Sheet

• Create/refresh .venv (uv): uv venv (add --clear to rebuild from scratch)
• Install / update (uv): uv sync (add --extra redis for Redis features, --no-dev for runtime-only)
• Install requirements only (uv): uv pip install -r requirements.txt
• Install / update (Poetry): poetry install / poetry add <package>
• Add a dependency: uv add <package> or poetry add <package> (both update pyproject.toml + poetry.lock)
• Run the app without activating a venv: uv run pharmagen or poetry run pharmagen
• Check the lockfile is current: uv lock --check or poetry lock --check

🔒 Security Best Practices

1. ✅ Never commit .env file to Git
2. ✅ Use environment variables for API keys
3. ✅ Enable rate limiting in production
4. ✅ Use HTTPS for public deployments
5. ✅ Keep dependencies updated
6. ✅ Monitor logs regularly

🐛 Troubleshooting

Common Issues

API Key Error:

# Check .env file
cat .env | grep GEMINI_API_KEY

Port Already in Use:

# Change port in .env
SERVER_PORT=8080

Module Not Found:

# Reinstall dependencies inside the uv-managed .venv
uv pip install -r requirements.txt

PDF conflict warning (PyFPDF vs fpdf2):

uv pip uninstall -y pyfpdf
uv pip install --upgrade fpdf2

See DEPLOYMENT.md for more troubleshooting.
