Salbutamol Tolerance Onset
RandomizedCrossoverTriple-blindBasic science
Summary
Overuse of inhaled bronchodilator beta agonist medication results in a loss of effectiveness (i.e. tolerance). This has been shown for the short acting beta agonist salbutamol and the long acting beta agonist salmeterol. Tolerance to salmeterol is present within 24 hours. The onset of tolerance to salbutamol is not known.
