Balancing Safety and Efficacy with Ease of Use to Meet the Needs of the Consumer-The Basics of OTC R&D.

The development of safe and effective products are the obvious goals of all drug research, but in the case of OTC products, it is also important to determine the most appropriate dosage and formulation in light of how these products will be used by consumers in the daily lives. By taking this approach, Taisho has developed such products as Dermarin L a treatment for athlete's foot for application once-a-day that is more effective then other medications requiring application three times a day, and the hemorrhoid treatment Preser Ace, the active ingredient of which is absorbed only through the affected area.

In OTC drug research, reactions to the taste and smell of substances are monitored and studied and the accumulated data used to perform actual experiments based on these observations.

To ensure that our products are of consistently high quality over their effective shelf life, we work to enhance the stability of active ingredients, as well as devote research to product containers and packaging materials
