Our Businesses

Pharmaceutical business

In the pharmaceutical business, we mainly manufacture and market prescription drugs and OTC drugs.
We research and develop generic drugs and other prescription drugs, aiming to provide better and more convenient drugs to medical settings.
We contribute to the health of people through the development and manufacture of high-quality and inexpensive generic drugs.
Our portfolios of corticosteroid external skin preparations and of antifungal external skin preparations consist of five dosage forms (ointments, creams, lotions, solutions, and gels), thereby satisfying the needs for efficacy, safety, ease of use, etc., and have acquired high market shares with trust from dermatologists and other physicians.
We also offer a wide range of disinfectants. Since the launch of Neojodin Solution in 1973, we have released five types of povidone-iodine disinfectants and mouthwashes, acquiring a high market share among generic drugs.

Iwaki Seiyaku confidently provides pharmaceuticals from their design to production, based on its research on external skin preparations and technologies regarding various dosage forms accumulated over many years.
