Switch OTC Drugs
Sato Pharmaceutical is focused on the development of products with higher added value,
keeping in mind market needs and trends. In particular, we are actively working to develop Switch OTC drugs,
which are pharmaceuticals that have been transferred to nonprescription status,
making them available for purchase at pharmacies and drugstores.
Once only available as pharmaceuticals prescribed by doctors, Switch OTC drugs are drugs approved for over-the-counter sales with relatively few side effects and a high level of safety. They are expected to play a major role in the practice of self-medication, not only in improving symptoms, but also in preventing illness and improving quality of life. Sato is actively promoting the development of Switch OTC drugs, which are expected to have an advantage in the market, and many of the products we have launched to date have captured top market share. We brought two products to market in 2025.
