Tác dụng
Description: Mechanism of Action: Beclometasone is a synthetic corticosteroid which controls the rate of protein synthesis. It depresses the migration of polymorphonuclear leucocytes and fibroblasts. Additionally, it controls and prevents inflammation by reversing the capillary permeability and lysosomal stabilisation at the cellular level. Pharmacokinetics: Absorption: Readily absorbed from sites of local application. Bioavailability: Approx 20% (beclometasone-17-monopropionate). Time to peak plasma concentration: Oral: 4 hours (beclometasone-17-monopropionate). Inhalation: 2 minutes. Distribution: Rapidly distributed to all body tissues. Volume of distribution: 20 L. Plasma protein binding: Inhalation: 94-96% (beclometasone-17-monopropionate). Metabolism: Metabolised mainly in the liver and in other tissues including the lung and gastrointestinal tract via rapid hydrolysis by esterase enzymes into beclometasone-17-monopropionate (B-17-MP) (major active metabolite) and other minor metabolites (beclometasone-21-monopropionate and beclometasone). Excretion: Mainly via faeces (as metabolites); urine. Elimination half-life: 0.5 hours (oral); 4 hours (inhalation).
