Drug Interactions

Increased fluticasone levels with CYP 3A4 inhibitors e.g ritonavir, ketoconazole, itraconazole. Additive effects with other β-agonist.

Contraindications

Not for primary treatment of status asthmaticus or other acute attacks of asthma.

Mechanism of Action

Salmeterol, a long acting β2-agonist which acts locally in the lung to mediate bronchodilation. Fluticasone, a corticosteroid with mainly glucocorticoid activity, reduce symptoms and exacerbations of asthma. Onset: Bronchodilation: 10-20 minutes. Duration: Bronchodilation: 12 hr Absorption: Salmeterol: Negligible absorption after inhalation. Fluticasone: Poorly absorbed from the GI tract; oral bioavailability <1%; absolute bioavailability of inhaled fluticasone: 5-11% (depending on device used). Distribution: Salmeterol: Protein binding: 96%. Fluticasone: Protein binding: 91%. Metabolism: Salmeterol: Extensive hepatic metabolism by hydroxylation; terminal elimination half-lives: 5.5 hr. Fluticasone: Extensive first-pass metabolism by cytochrome CYP3A4. Excretion: Salmeterol: Eliminated mainly in faeces; negligible amounts of unchanged salmeterol are detectable in urine or faeces. Fluticasone: Mainly excreted in faeces as metabolites and unchanged drug; <5% excreted in urine.
