Pranlukast Hydrate

Used as an adjunct to the standard therapy of inhaled steroids with inhaled long- and/or short-acting beta-agonists.

Pranlukast selectively antagonizes leukotriene D4 (LTD4) at the cysteinyl leukotriene receptor, CysLT1, in the human airway. Pranlukast inhibits the actions of LTD4 at the CysLT1 receptor, preventing airway edema, smooth muscle contraction, and enhanced secretion of thick, viscous mucus.
