Summary Fifty patients were admitted to a double‐blind, double‐dummy study comparing buccal morphine 10 mg tablets and intramuscular morphine sulphate 13.5 mg as premedication. This investigation was performed on the basis of favourable results obtained in an earlier 25 patient pilot study designed to examine the efficacy, safety and patient acceptability of buccal morphine 10 mg tablets as pre‐anaesthetic medication, Both studies and sets of results are presented and show that, whilst buccal morphine is a safe alternative means of delivering opioid premedication, which is acceptable to the majority of patients, an equivalent intramuscular morphine dose is nevertheless a more effective premedicant in terms of anxiolysis and wakefulness, as assessed by linear analogue scores. Pharmacokinetic considerations are advanced both to explain the differing clinical efficacies of the two means of morphine administration and to indicate that improved per‐ and immediate postoperative analgesia might be obtainable in patients premedicated with buccal morphine.
