Overview
DESCRIPTION Flunisolide Nasal Solution USP, 0.025% is intended for administration as a spray to the nasal mucosa. Flunisolide, the active component of Flunisolide Nasal Solution, is an anti-inflammatory steroid. Flunisolide is represented by the following structural formula: C 24 H 31 FO 6 Mol. Wt. 434.
Mechanism of Action
CLINICAL PHARMACOLOGY Flunisolide has demonstrated potent glucocorticoid and weak mineralocorticoid activity in classical animal test systems. As a glucocorticoid, it is several hundred times more potent than the cortisol standard. Clinical studies with flunisolide have shown therapeutic activity on nasal mucous membranes with minimal evidence of systemic activity at the recommended doses. A study in approximately 100 patients that compared the recommended dose of Flunisolide Nasal Solution with an oral dose providing equivalent systemic amounts of flunisolide has shown that the clinical effectiveness of Flunisolide Nasal Solution, when used topically as recommended, is due to its direct local effect and not to an indirect effect through systemic absorption.
