MeSH Pharmacological Classification
Agents that cause an increase in the expansion of a bronchus or bronchial tubes.
Compounds which inhibit or antagonize the biosynthesis or actions of phosphodiesterases.
Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system.
Drugs used to cause dilation of the blood vessels.
Applications
DescriptionIbudilast is a leukomene antagonist and phosphodiesterase inhibitor useful in the treatment of bronchial asthma. It antagonizes leukotriene D4-induced contractions of guinea pig ileum and tracheal muscles in virro, and inhibits eosinophil accumulation in vivo.
Usesa phosphodiesterase inhibitor with anti-inflammatory activity
UsesInhibitors of phosphodiesterase 4 (PDE4), which catalyzes the hydrolysis of cAMP, have potential applications in a variety of diseases, including asthma. Ibudilast is an inhibitor of PDE4 (IC50 = 54-239 nM) that, at higher doses, also inhibits PDE3 and PDE5 (IC50 = 1,600-3,510 nM). Through this action, it suppresses the elaboration of mediators involved in asthma and inflammation.[Cayman Chemical]
UsesA leukotriene D4 antagonist. Used as an antiallergic, antiasthmatic, and vasodilator (cerebral)
