Betamethasone-d5 is intended for use as an internal standard for the quantification of betamethasone (Item No. 20363) by GC- or LC-MS. Betamethasone is a synthetic corticosteroid.{64715} In vivo, betamethasone (5 mg/kg) reduces bronchoalveolar lavage fluid (BALF) matrix metalloproteinase-2 (MMP-2) and MMP-9 activities, TNF-? levels, and neutrophil number in a mouse model of LPS-induced lung injury. Prenatal administration of betamethasone (0.1 mg/kg) improves neonatal lung function but decreases hippocampal and corpus callosum neuron density and induces motor function deficits in a rabbit model of late preterm birth.{64716} It also extends gestational length in a rat model of preterm labor induced by high mobility group protein B1 (HMGB1).{64717} Formulations containing betamethasone have been used in the treatment of inflammatory skin conditions and prenatally to promote fetal lung maturation.
