Pharmaceutical D/P

The base of peculiar technology and materials offer

WATAHAN TRADING was established in 1965.The pharmaceutical department was one of three sales departments in the company, and began with the business of importing bulk drugs. Since 1969, the department's primary product has been suppository-based Witepsol, [manufactured and] sold pursuant to an exclusive arrangement. Watahan Trading was the only company able to supply this suppository-based product at that time. Sales of this product have grown significantly in Japan as a treatment of quadriceps contracture- an adverse drug reaction to injections of antipyretic in infants. Witepsol is now one of our leading products and promises to be a key component of our product line in the future.


Over the years, WATAHAN TRADING has developed its own unique technology to isolate the bulk substance from women's urine which is used to treat infertility.


The company has expanded beyond its original business of importing bulk drugs, and now also has an established laboratory with the highest standards for quality control, allowing for the manufacturing division to play a vital role in the pharmaceutical department. The company's manufacturing business also makes it easier to obtain import permission for new peptide bulk drugs.


Our experienced scientists and sales people work together to develop and promote new products and are committed to our customers' satisfaction. For quality, reliability and innovation you can trust, look no further than WATAHAN TRADING.
