Pfizer Japan Inc.
Eisai Co., Ltd.
Tokyo, Japan, June 11, 2010 — Pfizer Japan Inc. (Head Office: Tokyo; President: Ichiro Umeda) and Eisai Co., Ltd. (Headquarters: Tokyo; President & CEO: Haruo Naito) announced that the two companies will launch postherpetic neuralgia treatment Lyrica® Capsules (generic name: pregabalin) on June 22, 2010.
Lyrica® was approved in Japan on April 16 of this year and was today listed in the NHI drug price list. Pfizer Japan and Eisai are jointly promoting sale of the drug and work together to ensure the provision of information regarding its proper usage.
Developed by Pfizer Inc. (USA), Lyrica® is currently approved in over 105 countries worldwide. Its major mechanism of action is thought to express its analgesic effects by suppressing the output of various neurotransmitters from overexcited nerves. The efficacy and safety of Lyrica® have already been proven in a number of clinical trials. Lyrica® is also listed as a first-line drug in the treatment guidelines / algorithm for neuropathic pain (including postherpetic neuralgia) in the United States and Europe.
Postherpetic neuralgia (PHN) is a disorder representative of peripheral neuropathic pain caused by nerve damage. Herpes zoster appears when viral resistance is lowered due to latent neuromuscular infection by varicella / herpes zoster viruses following first infection with chicken pox. PHN is considered an intractable pain, and symptoms include continued burning or electric shock-like pain after skin symptoms of herpes zoster have healed.
Lyrica® has a new mechanism of action that is completely different from existing analgesic treatments, and domestic phase III trials have confirmed the efficacy and safety of its analgesic effects. The drug is also under review for indication approval for peripheral neuropathy, and development is underway to secure indication for fibromyalgia.
Both Pfizer Japan Inc. and Eisai Co., Ltd. will contribute to the QOL improvement for patients with PHN by providing Lyrica® Capsules as a new treatment.
