The application and pharmacologic action of Ibudilast

Aug 23，2019

Ibudilast is an anti-inflammatory and neuroprotective oral agent which shows an excellent safety profile at 60 mg/day and provides significantly prolonged time-to-first relapse and attenuated brain volume shrinkage in patients with relapsing-remitting (RR) and/or secondary progressive (SP) multiple sclerosis (MS). Ibudilast is currently in development in the U.S. (codes: AV-411 or MN-166), but is approved for use as an antiinflammatory in Japan.

Application

In Japan, ibudilast oral capsules are approved for the treatment of asthma, and for improvement of dizziness secondary to chronic cerebral circulation impairment associated with sequelae of cerebral infarction.Ibudilast ophthalmic solution is indicated for the treatment of allergic conjunctivitis and hay fever.

Pharmacologic action

Ibudilast has bronchodilator, vasodilator and neuroprotective effects, and is mainly used in the treatment of asthma and stroke. It inhibits platelet aggregation,and may also be useful in the treatment of multiple sclerosis.
Ibudilast crosses the blood–brain barrier and suppresses glial cell activation. This activity has been shown to make ibudilast useful in the treatment of neuropathic pain and it not only enhances analgesia produced by opioid drugs, but also reduces the development of tolerance.
