Although patients receiving systemic corticosteroid therapy are more susceptible to secondary infection than patients not receiving corticosteroids, administration via the inhaled route minimizes this risk. Corticosteroid therapy can mask the symptoms of infection and should not be used in cases of bacterial, fungal, or viral infections that are not adequately controlled by anti-infective agents, except in life-threatening circumstances. Fluticasone; salmeterol should be avoided in patients with tuberculosis infections of the respiratory tract if possible. The incidence or course of acute bacterial or viral infection is probably minimally affected by inhaled corticosteroids in immunocompetent individuals; however, close monitoring of patients with immunosuppression is recommended if treatment with an inhaled corticosteroid is necessary.

Elimination: The elimination rate of intravenous administered fluticasone propionate is linear over the 250-1000mcg dose range and are characterized by a high plasma clearance (CL=/min). Peak plasma concentrations are reduced by approximately 98% within 3-4 hours and only low plasma concentrations were associated with the terminal half-life. The renal clearance of fluticasone propionate is negligible (<%) and less than 5% as the carboxylic acid metabolite. The major route of elimination is the excretion of fluticasone propionate and its metabolites in the bile.

Fluticasone propionate is a highly selective agonist at the glucocorticoid receptor with negligible activity at androgen , estrogen , or mineralocorticoid receptors , thereby producing anti-inflammatory and vasoconstriction effects. It has been shown to have a wide range of inhibitory effects on multiple cell types (. mast cell , eosinophil , neutrophil , macrophages , and lymphocytes ) and mediators (. histamine , eicosanoids , leukotrienes , and cytokines ) involved in inflammation . Fluticasone propionate is stated to exert a topical effect on the lungs without significant systemic effects at usual doses, due to its low systemic bioavailability .
