Diamorphine 2.5-7.5 mg produced neither sleepiness nor a deterioration in blood gases. However, plasma levels associated with analgesic efficacy were not achieved with these doses. Thus, as given in this study, oral diamorphine is unlikely to have therapeutic potential in the treatment of dyspnoea in the "pink puffer" syndrome. ER -
