Sample Use Guides

The usual adult dosage for oral use is 450 mg of pranlukast hydrate (4 capsules) daily in two divided doses after each meal in the morning and evening. The dosage may be adjusted according to the patient's age and symptoms.
Route of Administration: Oral
The activity of pranlukast was measured using calcium mobilization assay. HEK 293 cells stably expressing CysLT1 receptor and Gα16 protein were loaded with 2 uM Fluo-4 AM in Hanks balanced salt solution buffer. The compound was added to a solution, and after 10 min incubation at room temperature, 25 uL LTD4 was dispensed into the well using a FlexStation II microplate reader, and intracellular calcium change was recorded with an excitation wavelength of 485 nm and an emission wavelength of 525 nm. The IC50 for pranlukast was 23 nM.
