Double-blind, crossover comparison of carbuterol and salbutamol

The bronchodilator efficacy of oral carbuterol in the dose of 2 mg or 3 mg was compared with that of 4 mg salbutamol in a double-blind, crossover trial in 21 patients with bronchial asthma. Carbuterol 3 mg was found to be a more effective bronchodilator than salbutamol 4 mg. Both the drugs in these doses produced mild tachycardia but were otherwise well tolerated.
