Description and Uses

Beclomethasone dipropionate is claimed to exert a topical effect on the lungs without significant systemic activity. It is used by inhalation, generally from a metered aerosol, for the prophylaxis of the symptoms of asthma.

Beclomethasone has been used in MS?MS (mass spectrometry) methods for the analysis of β-agonists, corticosteroids, chloramphenicol and penicillins. It has also been used to find the differential response of glucocorticoids in larval regeneration model.
