Biochem/physiol Actions

Betamethasone is used to treat neonatal respiratory distress syndrome, and psoriasis.

Diagnostic Implications

Betamethasone is a corticosteroid with anti-inflammatory and immunosuppressive abilities, used especially where water retention is undesirable. It is applied as a topical cream, ointment, lotion or gel to treat itching (e.g. from eczema). Corticosteroid used to stimulate fetal lung maturation and to decrease the incidence and mortality from intracranial hemorrhage in premature infants

We designed a temperature-responsive and biodegradable novel drug-delivery carrier. A block copolymer, poly (N-isopropylacrylamide-dl-lactide) (PNIPAAm-PLA), was synthesized by the ring-opening polymerization of dl-lactide, and used as a carrier for a drug-delivery system. In this study, temperature-responsive nanoparticles (NPs) encapsulating betamethasone
