Dược Lực Học : Flunisolide is a synthetic corticosteroid. It is administered either as an oral metered-dose inhaler for the treatment of asthma or as a nasal spray for treating allergic rhinitis. Corticosteroids are naturally occurring hormones that prevent or suppress inflammation and immune responses. When given as an intranasal spray, flunisolide reduces watery nasal discharge (rhinorrhea), nasal congestion, postnasal drip, sneezing, and itching oat the back of the throat that are common allergic symptoms.
Cơ Chế Tác Dụng : Flunisolide (marketed as AeroBid, Nasalide, Nasarel) is a corticosteroid often prescribed as treatment for allergic rhinitis. The principle mechanism of action of flunisolide is to activate glucocorticoid receptors. It also has anti-inflammatory action. Flunisolide is a glucocorticoid receptor agonist. The antiinflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibition arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes. The immune system is suppressed by corticosteroids due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding. Flunisolide binds to plasma transcortin, and it becomes active when it is not bound to transcortin.
Dược Động Học :
▧ Absorption :
Absorbed rapidly
▧ Protein binding :
Approximately 40% after oral inhalation
▧ Metabolism :
Primarily hepatic, converted to the S beta-OH metabolite.
▧ Half Life :
1.8 hours
Chỉ Định : For the maintenance treatment of asthma as a prophylactic therapy.
Tương Tác Thuốc :
  • Telithromycin Telithromycin may reduce clearance of Flunisolide. Consider alternate therapy or monitor for changes in the therapeutic/adverse effects of Flunisolide if Telithromycin is initiated, discontinued or dose changed.
  • Voriconazole Voriconazole, a strong CYP3A4 inhibitor, may increase the serum concentration of flunisolide by decreasing its metabolism. Monitor for changes in the therapeutic and adverse effects of flunisolide if voriconazole is initiated, discontinued or dose changed.
