描述 | Fluticasone propionate is a new corticosteroid based on the androstane nucleus. It is more lipophilic than beclomethasone dipropionate (BDP) and budesonide, and binds more avidly to human lung tissue. It has an absolute affinity (KD) of 0.5 nM for the glucocorticoid receptor and a relative receptor affinity 1.5- and 3.0-times greater than that of beclomethasone-17-monopropionate (17-BMP) and budesonide, respectively. The rate of association with the receptor is faster and the rate of dissociation slower than with standard corticosteroids. Pretreatment with fluticasone propionate significantly inhibits the increase in mast cell numbers in the nasal mucosa of rats chronically exposed to toluene di-isocyanate (TDI), and suppresses TDI-induced mast cell degranulation. Fluticasone propionate therefore has increased intrinsic glucocorticoid potency and high topical anti-inflammatory activity[3]. Fluticasone propionate is a potent topical anti-inflammatory corticosteroid with low systemic activity. Fluticasone propionate generally demonstrated similar efficacy compared with intranasal beclomethasone dipropionate, flunisolide acetonide and oral astemizole and better or a trend towards better efficacy compared with oral loratadine, terfenadine, cetirizine and intranasal sodium cromoglycate (cromolyn sodium) against nasal symptoms[4]. Inhaled fluticasone propionate < or =500 microg/day is an effective anti-inflammatory therapy for mild to moderate asthma in adolescents and adults[5]. |
