Raw research findings for this medication. Mostly single studies, not curated or confirmed robust.
Flunisolide is a corticosteroid used as an inhaler for asthma (AeroBid, Aerospan) and as a nasal spray for allergic rhinitis. Like other inhaled steroids, it calms inflammation in the airways, and the liver clears most of what is swallowed.
Flunisolide is broken down quickly by the liver, mainly by CYP3A4. The gene studies listing it came from studies of inhaled steroids in asthma and looked at GLCCI1 and TBXT for how much lung function improved. The findings come from a few studies, and there is no CPIC or DPWG guideline.
