The effects and side effects in steady state of a sustained-release preparation of terbutaline 7.5 mg twice daily were compared with ordinary tablets 5 mg three times daily. The study performed for two weeks was double-blind, double-dummy, cross-over with randomized allocation of the drugs. 20 patients completed the trial and the results show higher mean morning PEFR values and a tendency to milder side effects with depot tablets.
