Occasionally, it may cause a cough upon inhalation. Deposition on the tongue and throat may promote oral candidiasis, which appears as a white coating, possibly with irritation.

Pharmakokinetische Eigenschaften
Der Arzneistoff Beclometason-17,21-dipropionat wird seit 1972 als Prodrug eingesetzt. Nach Hydrolyse durch Esterasen entsteht der aktive Metabolit Beclometason-17-monopropionat. In der Leber werden sie mittels First-Pass-Effekt in pharmakologisch inaktive Metaboliten wie Beclometason-21-monopropionat und Beclometason (freier Alkohol) umgewandelt. Dies begrenzt die systemische Bioverfügbarkeit und Toxizität.
Wirkung
Beclometason wirkt entzündungshemmend, immunsuppressiv und antiallergisch. Es wird somit zur Behandlung von asthmatischen Erkrankungsformen und Atembeschwerden eingesetzt. Die volle Wirkung tritt erst nach einigen Stunden bzw. Tagen ein.
