The active component of XHANCE is fluticasone propionate, a corticosteroid, having the chemical name S -(fluoromethyl) 6α,9-difluoro-11β,17-dihydroxy-16α-methyl-3oxoandrosta-1,4-diene-17β-carbothioate, 17‑propionate and the following chemical structure: Fluticasone propionate is a white powder with a molecular weight of 500.57, and the empirical formula is C 25 H 31 F 3 O 5 S. It is practically insoluble in water, freely soluble in dimethylformamide, sparingly soluble in acetone and dichloromethane, and slightly soluble in 96% ethanol. XHANCE (fluticasone propionate) nasal spray, 93 mcg, for nasal administration, with an exhalation delivery system that delivers an aqueous suspension of microfine fluticasone propionate having a particle size distribution in the range of 0 to 5 microns for topical nasal administration by means of a metering, atomizing spray pump and exhaled breath. XHANCE also contains microcrystalline cellulose and carboxymethylcellulose sodium, dextrose, benzalkonium chloride, polysorbate 80, edetate disodium dihydrate, sodium hydroxide and hydrochloric acid (to adjust pH), and purified water, and has a pH between 5 and 7. Before initial use, prime XHANCE by gently shaking and then pressing the amber glass bottle 7 times or until a fine mist appears. When XHANCE has not been used for ≥ 7 days, prime again by releasing 2 sprays into the air, away from the face [see Dosage and Administration ( 2.2 ) and Instructions for Use ] . After priming, each spray delivers 93 mcg of fluticasone propionate in an aqueous suspension through the cone-shaped nosepiece. The system also has a flexible mouthpiece. Within the device is a non‑removable amber glass bottle with a metering spray pump, an applicator, and a valve that prevents release of breath until the bottle is pressed. A base covers the bottom of the bottle, and a removable orange cap covers both the nosepiece and mouthpiece. Chemical Structure
