Indications

Adults and adolescents over 16 years of age: Prophylactic management in severe asthma (patients requiring high dose inhaled or oral corticosteroid therapy).

Children and adolescents from 4 to 16 years of age: Treatment of mild to moderate acute exacerbations of asthma.

Pharmacology

Fluticasone propionate is a synthetic, trifluorinated glucocorticoid with potent anti-inflammatory activity. In vitro assays using human lung cytosol preparations have established fluticasone propionate as a human glucocorticoid receptor agonist with an affinity 18 times greater than dexamethasone, almost twice that of beclomethasone-17-monopropionate (BMP), the active metabolite of beclomethasone dipropionate, and over 3 times that of budesonide. Data from the McKenzie vasoconstrictor assay in man are consistent with these results.

The precise mechanisms of glucocorticoid action in asthma are unknown. Inflammation is recognized as an important component in the pathogenesis of asthma. Glucocorticoids have been shown to inhibit multiple cell types (e.g., mast cells, eosinophils, basophils, lymphocytes, macrophages, and neutrophils) and mediator production or secretion (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in the asthmatic response. These anti-inflammatory actions of glucocorticoids may contribute to their efficacy in asthma.

Though highly effective for the treatment of asthma, glucocorticoids do not affect asthma symptoms immediately. However, improvement following inhaled administration of fluticasone propionate can occur within 24 hours of beginning treatment, although maximum benefit may not be achieved for 1 to 2 weeks or longer after starting treatment. When glucocorticoids are discontinued, asthma stability may persist for several days or longer.

Dosage & Administration

Adults and adolescents over 16 years (prophylactic management in severe asthma): 0.5-2 mg twice daily. The recommended initial dose is 2 mg twice daily. The dosage should then be adjusted until control is achieved or reduced to the minimum effective dose according to the individual response.

Children and adolescents 4 to 16 years of age (treatment of acute exacerbations of asthma): 1 mg twice daily.

Interaction

Clinically significant drug interactions mediated by Fluticasone Propionate are unlikely.

Contraindications

Fluticasone Propionate Nebuliser Suspension is contraindicated in patients with a history of hypersensitivity to any component of the preparation.

Side Effects

Candidiasis of the mouth and throat and/or hoarseness is commonly reported. Patients may find it helpful to rinse out their mouth with water after inhalation. As with other inhalation therapy, paradoxical bronchospasm may occur rarely, with an immediate increase in wheezing after dosing. There have also been rare reports of hypersensitivity reactions manifesting as angioedema, bronchospasm and very rarely, anaphylactic reactions. Other adverse events that may occur rarely include depression of plasma cortisol in adult patients on higher doses, bone density reduction, growth retardation, cataract, glaucoma.

Pregnancy & Lactation

Pregnancy category B3. There is inadequate evidence of safety of Fluticasone Propionate in human pregnancy. However, as with other drugs the administration of Fluticasone Propionate during pregnancy should only be considered if the expected benefit to the mother is greater than any possible risk to the foetus.

Use in Lactation: The excretion of Fluticasone Propionate into human breast milk has not been investigated.

Precautions & Warnings

Fluticasone Propionate Nebuliser Suspension should not be used for the treatment of severe acute exacerbations of asthma in children and adolescents as efficacy in this situation has not been established. Patients receiving treatment with nebulised Fluticasone Propionate must be warned that if their clinical condition deteriorates, or if a dose fails to give the usual relief, they should not increase the dose or the frequency of administration, but should seek medical advice. Prolonged therapy with inhaled Fluticasone Propionate Nebuliser Suspension should be reduced gradually and not stopped abruptly, and this should be done under medical supervision.

Overdose Effects

Acute inhalation of Fluticasone Propionate doses in excess of those recommended may lead to temporary suppression of adrenal function. This does not need emergency action as adrenal function is recovered in a few days, and can be verified by plasma cortisol measurements. However, if higher than recommended dosage is continued over prolonged periods, some degree of adrenal suppression may result. Monitoring of adrenal reserve may be necessary. In cases of Fluticasone Propionate overdose, therapy may still be continued at a suitable dosage for symptom control.
