The Anti Osteoporosis Drug Clodronate is Effective for Chronic Pain Treatment! World-first Discovery of Its Mechanism
July 19(Wed), 2017
A collaborative research group of Specially Appointed Assistant Professor Yuri Kato and Associate Professor Takaaki Miyaji of the Advanced Science Research Center, Okayama University, together with the Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University, Matsumoto Dental University, Kurume University, Tohoku University, Kyushu University, Tokyo University of Agriculture and Ajinomoto Co., Inc. has discovered for the first time in the world that inhibition of the transporter (VNUT) that transports ATP to vesicles by the anti-osteoporosis drug clodronate can contribute to alleviation of neuropathic, inflammatory and other chronic pain. The research results were published in the electronic version of “Proceedings of the National Academy of Sciences of the United States of America (PNAS)” at noon on July 18th, 2017 in the U.S.
It is said that 20 to 25% of the world’s population suffers from chronic pain, but effective analgesic drugs with little side effects have yet to be developed. With these research results, we are able to offer a completely new type of analgesic and anti-inflammatory drug that targets a particular transporter. Clodronate is approved for clinical use in many European countries and the U.S., and its clinical safety in humans is well established. Drug repositioning can help shorten the length of the development period and lower development costs, so we can expect the research results to provide benefits to society soon.
Clodronate-evoked inhibition of vesicular ATP release is important for the treatment of chronic pain.
