Prenast was first developed by Ono in Japan as an anti-asthma drug, and was marketed in Japan in 1995. In 1999, it was found to treat allergic rhinitis.Prenast is leukotriene C4/D4 receptor antagonist antibody (LTRAS) with very low toxicity. It can selectively inhibit the leukotriene skin activity of airway smooth muscle, and has almost no effect on arachidonic acid metabolic enzymes. At the same time, it has no antagonistic effect on acetylcholine and 5-hydroxytryptamine, and has significant inhibition on LTC4, LTD4 and LTE4.
