Mometasone furoate nasal spray

Mometasone furoate nasal suspension is supplied as an aqueous suspension with an atomizing pump that dispenses 50 pg per metered spray. The total daily dose for mometasone furoate is 200 pg. 

Beclomethasone dipropionate, triamcinolone acetonide, budesonide, flunisolide, and mometasone furoate are available as nasal sprays for the topical treatment of allergic rhinitis. They are effective at doses (one or two sprays one, two, or three times daily) that in most patients result in plasma levels that are too low to influence adrenal function or have any other systemic effects. 

In this chapter, analysis of the excipient in Nasonex (mometasone naral spray) is used as a typical example to demonstrate how to select a proper analytical method. Nasonex Nasal Spray contains Mometasone Furoate, microcrystalline cellulose, and carboxymethylcellulose sodium NF, citric acid USP, sodium citrate USP, benzalkonium chloride solution NF, glycerin USP, polysorbate 80 NF, phenylethyl alcohol USP, and water USP. 

Nasonex nasal spray, 50 meg is a metered-dose, manual-pump spray unit containing an aqueous suspension of mometasone furoate monohydrate equivalent to 0.05% w/w mometasone furoate, calculated on the anhydrous basis, in an aqueous medium containing glycerin, micro-... 

Nasal suspensions can be characterised by thixotropic properties [41]. Nasal sprays containing triamcinolone acetonide or mometasone furoate showed time-dependent, reversible loss of viscosity under shear (shaking or spraying,) flowing more freely. Recovery of viscosity after application is likely to inhibit suspension flowing out from the nasal cavity [42, 43].
