Description: Beclometasone (as diproprionate) is a prodrug w/ potent glucocorticoid and weak mineralocorticoid activity. It controls the rate of protein synthesis, depresses the migration of polymorphonuclear leukocytes, reduces fibroblast activity, and reverses capillary permeability and lysosomal stabilisation at the cellular level to prevent or control inflammation.
Onset: W/in a few days up to 2 wk.
Pharmacokinetics:
Absorption: Readily absorbed from the resp and GI tract. Absolute bioavailability: 44% (nasal). Time to peak plasma concentration: 0.5 hr (inhalation).
Distribution: Rapidly distributed to all body tissues. Volume of distribution: 20 L. Plasma-protein binding: 87%.
Metabolism: Undergoes hydrolysis by pulmonary esterases to major active metabolite, beclometasone-17-monopropionate (17-BMP), during absorption; subsequently undergoes metabolism in the liver by CYP3A4 enzyme to less active metabolites, beclometasone-21-monopropionate (21-BMP) and beclometasone. Undergoes first-pass metabolism in the liver and/or GI tract (oral).
Excretion: Via faeces (60% mainly as metabolites) and urine (<10-12% as free and conjugated metabolites). Elimination half-life: 0.5 hr.
