Description |
Ablukast (Ro 23-3544) is a specific and active leukotriene receptor antagonist. Ablukast effectively reduces LTC4- and antigen-induced bronchoconstriction[1][2]. Ablukast is LTD4 receptor antagonist[3].

In Vitro |
Ablukast (Ro 23-3544) is tested for its efficacy in modulating dinitrofluorobenzene (DNFB)-induced allergic and croton oil-induced irritant contact dermatitis in mouse ears. Treatment shortly after elicitation of the dermatitis, and for up to 5 days thereafter, was moderately effective in suppressing DNFB-induced ear swelling in a dose-dependent fashion. Daily pre-treatment of the ears for 1 week causes a more marked reduction of DNFB-induced ear swelling during the first 48 h after elicitation[2].

Animal Model: Female BALB/c mice[2] Dosage: Concentrations of 0.1 , 0.5 , 1.0 and 5.0 % of Ablukast Administration: Applied to one of the pretreated ears 1 h after elicitation and at 24 h intervals on the following 4 days; three times daily Result: Effectively reduced DNFB-induced ear swelling.
