Levostar Tablet 1 gm

L-Salbutamol is a single isomer ?-2 agonist that differs from racemic salbutamol by elimination of S-salbutamol. L-Salbutamol is an effective bronchodilator whose primary mechanism of action is unimpeded by (S)-salbutamol. Thus, when compared with racemic salbutamol, clinically comparable bronchodilation can be achieved with doses that substantially lessen beta-mediated side effects.
