Specialists in Transdermal Medication.

Drawing on many years of experience and expertise in the field of anti-inflammatory and analgesic plasters, development work at Teikoku Seiyaku is now proceeding in two directions. The first focuses on new products for other therapeutic areas, employing transdermal (through the skin) absorption technology, which is an offshoot of our specialty in anti-inflammatory analgesic plasters. The general perception is that medication is taken orally, but some drugs are best delivered transdermally to minimize adverse reactions. As experts in transdermal absorption technology, we feel that such products have great potential for a wide variety of applications. Our second area of product development is in pain-relief products. In addition to a fentanyl tape to address cancer pain, Teikoku commercializes Murphine Sulfate and oxycodone hydrochloride capsules as well as methadone hydrochloride tablets. In addition, Teikoku is one of the few manufacturers licensed to handle narcotic drugs for medical use in Japan and abroad.
