*1: α (Alpha 2 delta) ligand           

α2δ ligand binds to the α2δ subunits of voltage-dependent calcium channels.


*2: Diabetic peripheralneuropathic pain (DPNP)

DPNP is a typical example of PNP caused by nerve damage. Diabetic peripheral neuropathy is a disorder that causes neuropathy and numbness to the extremities and is one of the most common long-term 3 major complications of diabetes. Its symptoms include severe pain, hyperalgesia, numbness, impairment of equilibrium and muscle movements, burning pain and pricking pain. Pain is often exacerbated during the night and may cause sleep disorders. Of the diabetic population estimated to exceed 10 million in Japan, 9- 22% of the patients are reported to suffer DPNP.


*3: Postherpetic neuralgia (PHN)

PHN is a typical example of PNP caused by nerve damage. Onset of herpes zoster is caused by a decline of immunity against varicella-zoster virus which established latent infection in ganglia. In PHN, burning pain or pain shooting through the body like electricity persists even after cure of herpes zoster. It is regarded as one of the intractable pains, which cause muscle weakness and paralysis in rare cases. PHN is reported to affect 10-25% of the 500-600 thousand Japanese who develop herpes zoster annually.


 *4: Peripheralneuropathicpain (PNP)              

PNP is caused by damage or functional abnormality of peripheral nerves due to various causes. Typical PNPs are diabetic PNP (DPNP)*2 and postherpetic neuralgia (PHN) *3.
