Ibudilast is a phosphodiesterase inhibitor ......by BioVision, Inc.,
Ibudilast, also known as AV-411, KC-404 and MN-166, is an antiinflammatory drug used mainly in Japan, which acts as a phosphodiesterase inhibitor, inhibiting the PDE-4 subtype to the greatest extent, but also showing significant inhibition of other PDE subtypes. 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. ......by MedKoo Biosciences, Inc.
Ibudilast is a relatively non-selective phosphodiesterase inhibitor with anti-inflammatory and neuroprotective activities. ......by Selleck Chemicals LLC
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. ......by Target Molecule Corp.
