VIENNA, Austria-A new oral inhalation system for morphine is almost as efficient as IV dosing, Aradigm Corp and SmithKline Beecham researchers reported at the 9th World Congress on Pain. B. A. Otulana, MD, said that the dose-corrected bioavailability of morphine with the new device was 75% of that with intravenous morphine, a major increase over the 5% bioavailability achieved with other nebulizers. This approach might provide a useful, noninvasive alternative to parenteral morphine administration.
