Bioactivity | Betamethasone is a synthetic glucocorticoid with anti-inflammatory and immunosuppressive activities. Betamethasone accelerates fetal lung maturation and induces gene expression and apoptosis[1][2][3][4]. |
Invitro | Betamethasone (0.1-1 μM; 12 h) induces gene expression in L929 cells[4].Betamethasone (0.1-1 μM; 48 h) induces CEM C7 T-cells apoptosis[4]. |
In Vivo | Betamethasone (0.48 mg; i.v.gtt for 48 h) decreases the hypercapnia-induced increase in CBF due to decreased cerebral vasodilatation[1].Betamethasone (0.05 ml (1 mg/L); topical injection) ameliorates spinal nerve transection induced mechanical allodynia and thermal hyperalgesia, and reduces the activation of NF-κB and elevation of TNFα and IL-1β, and induces the expression of IL-10 in the rats brain[2].
