Pranlukast (brand name Onon, オノン) is a cysteinyl leukotriene receptor-1 antagonist. This drug works similarly to Merck & Co.'s montelukast (Singulair). It is widely used in Japan.

Medications of this class, which go under a variety of names according to whether one looks at the American, British or European system of nomenclature, have as their primary function the antagonism of bronchospasm caused, principally in asthmatics, by an allergic reaction to accidentally or inadvertently encountered allergens.
