Our Strategy and Results
Pursuing the Essence
The team members full of expertise, curiosity, flexibility, judgment, and execution power never settle for the status quo, never give up, and tirelessly tackle problem-solving every day.
Developing Trace Analysis
Using high-performance, state-of-the-art analytical instruments, the team members are developing efficient analytical methods to rapidly and accurately measure "trace amounts of nitrosoamines contained in medicines," ensuring that products are delivered to the market without any blemishes.
Creation of NOx Removal System
We have developed the excellent NOx removal system by considering every possible measure and through trial and error to reduce NOx to a few ppb levels (akin to finding one person in a country with a population of one billion).
Refine APIs/DPs Manufacturing Process
Manufacturing methods, equipment, and environment for Active Pharmaceutical Ingredients (APIs) and Drug Products (DPs) are carefully reviewed one by one to reliably and proactively prevent the contamination of nitrosoamines.
Refine Packaging Materials and Storage Methods
We select packaging materials that ensure no contamination with nitrosoamines can occur, confidently delivering safe and secure pharmaceuticals to the market.
