XHANCE

The activity of XHANCE is due to the parent drug, fluticasone propionate. Due to the low bioavailability by the nasal route, the majority of the pharmacokinetic data were obtained via other routes of administration.

AbsorptionThe mean (SD) peak exposure (C max ) and total exposure (AUC 0-∞ ) following administration of a dose of 186 mcg of XHANCE during exhalation were 17.2 ± 7.40 pg/mL and 111.7 ± 49.75 pg·h/mL, respectively, and were 25.3 ± 10.34 pg/mL and 171.7 ± 85.55 pg·h/mL, respectively,...

14.1 Chronic Rhinosinusitis with Nasal Polyps The efficacy of XHANCE was evaluated in two randomized, double-blind, parallel‑group, multicenter, placebo-controlled, dose-ranging trials in adults 18 years and older with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) and associated moderate to severe nasal congestion (Trial 1 [NCT01622569], Trial 2 [NCT01624662]). The two trials included a total of 646 patients [348 (53.9%) males and 298 (46.1%) females] with a mean age of 45.5 years. Patients were randomized 1:1:1:1 to receive 93 mcg, 186 mcg, or 372 mcg twice daily or placebo for a period o...

XHANCE is contraindicated in patients with hypersensitivity to any of the ingredients [see Warnings and Precautions ( 5.3 ) and Description ( 11 )] . Hypersensitivity to any ingredient in XHANCE. ( 4 )

Local Nasal Adverse Reactions: epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing. Monitor patients periodically for signs of adverse effects on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma. ( 5.1 ) Glaucoma and Cataracts may occur with long-term use. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use XHANCE long-term. ( 5.2 ) Hypersensitivity react...

7 DRUG INTERACTIONS Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid effects. ( 7.1 ) 7.1 Inhibitors of Cytochrome P450 3A4 Fluticasone propionate is a substrate of CYP3A4. The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinav...
