Theophylline manufacturer?

There isn’t a single manufacturer. Theophylline is a generic drug produced by many companies around the world, so the exact manufacturer depends on your country and the specific product.

Common manufacturers of theophylline tablets/solutions (examples):
- Teva
- Sandoz (Novartis)
- Viatris (formerly Mylan)
- Sun Pharma
- Lupin
- Cipla
- Dr. Reddy's
- Zydus Cadila
- Glenmark
- Aurobindo
- Torrent

If you can tell me your country and whether you want theophylline or aminophylline (and the dosage/form you need), I can suggest current options from local suppliers or help you check what your pharmacy carries.
