Daiichi Sankyo and AstraZeneca Launch NEXIUM 10mg and 20mg Capsules in Japan
TOKYO, Japan (September 15, 2011) − Daiichi Sankyo Co., Ltd. (hereafter, Daiichi Sankyo) and AstraZeneca KK (hereafter, AstraZeneca) today announced the launch of NEXIUM® Capsule
(esomeprazole magnesium) 10mg and NEXIUM® Capsule 20mg following the NHI (National
Health Insurance) drug price listing received on September 12, 2011.
The NHI reimbursement price is 96.70 yen for NEXIUM® Capsule 10mg, and 168.90 yen for
NEXIUM® Capsule 20mg. (Approval for manufacture and marketing: July 1, 2011; NHI drug price
listing: September 12, 2011)
The active ingredient in NEXIUM® Capsules, esomeprazole magnesium, is one of the two isomers in omeprazole, the active substance in Omepral®. Esomeprazole selectively inhibits the
activity of the enzyme H+/K+- ATPase, the acid pump. Esomeprazole thus inhibits the final step
in the regulation of acid secretion and thereby provides effective control of acid-related conditions. NEXIUM® Capsules has been globally approved and is currently sold in more than 120 countries
and regions, backed up by rich and robust clinical evidence/experience. In the phase III clinical
studies for reflux esophagitis patients in Japan, NEXIUM® Capsules demonstrated a quick relief
of symptoms, endoscopic healing, patient tolerability and a good safety profile.
Under the terms of this agreement, AstraZeneca and Daiichi Sankyo will co-promote NEXIUM®
Capsules in Japan. AstraZeneca will manufacture and develop the product and Daiichi Sankyo
will be responsible for its sales and distribution. Daiichi Sankyo and AstraZeneca are determined to contribute to the needs of patients with acid- related conditions in Japan by maximizing the value of NEXIUM® Capsules through their strong
collaboration.
