Product Information
| Description: | Levosalbutamol tartrate(levalbuterol) is the R-enantiomer of the short-acting β2-adrenergic receptor agonist salbutamol. IC50 Value: Target: β2-adrenergic receptor Levosalbutamol and salbutamol produced significantly better bronchodilator responses than placebo. Both the drugs showed equivalent time-dependent bronchodilator responses as measured by area under curve for percent change in FEV(1) and FVC over 6h. The time to onset of action, mean maximum bronchodilator response and duration of bronchodilator response were similar between levosalbutamol and salbutamol . |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
