Levalbuterol ((R)-Albuterol) hydrochloride is a short-acting β2-adrenergic receptor agonist and the active (R)-enantiomer of Salbutamol. Levalbuterol hydrochloride is a more potent bronchodilator than Salbutamol and has the potential for the treatment of COPD[1].

| In Vitro | Levalbuterol (10 μM; 24 hours) hydrochloride induces 11β-HSD1 mRNA expression, however, it does not influence 11β-HSD2expression in airway epithelial cells[1]. Levalbuterol (10 μM; 24 hours) hydrochloride significantly reduces both LPS- and TNF-α-induced NF-κB activity while increasing GRE activation in an 11β-HSD1 dependent manner in a transformed mouse airway epithelial cell line[1]. RT-PCR[1] Cell Line: Murine Club (MTCC) cells Concentration: 10 μM Incubation Time: 24 hours Result: Increased 11β-HSD1 mRNA expression selectively. |
| In Vivo | Levalbuterol (subcutaneous injection; 1 mg/kg; 14 days) hydrochloride significantly decreases pulmonary inflammation in OVA mice, demonstrated a decrease in eosinophilia and IgE[2]. Animal Model: C57BL/6 female mice with a pulmonary allergic model[2] Dosage: 1 mg/kg Administration: Subcutaneous injection; 1 mg/kg; 14 days Result: Decreased pulmonary inflammation after OVA sensitization. |
