the results suggest that enhancement of the early bronchodilator response obtained by adding oxitropium bromide to a conventional dose of salbutamol in patients with stable asthma reflects suboptimal dosing of salbutamol rather than differences between the agents in mechanisms of action , whereas enhancement in duration of response is related also to the pharmacological characteristics of oxitropium bromide .
