Bronchodilator activity resides in R-(-)-Salbutamol (eutomer); S-Salbutamol (distomer) is inactive. The active (R)-enantiomer undergoes significantly faster metabolism than the inactive (S)-(+)-enantiomer after oral administration. Distomer is cleared more slowly and hence tends to accumulate in preference to eutomer. These pharmacokinetic and pharmacodynamic differences provided the basis for chiral switch of salbutamol to levosalbutamol.
