Clinical TrialEffect of nebulized morphine in cancer patients with dyspnea: a pilot study.
It is known that opioids may decrease subjective dyspnea. The recent finding that opioid binding sites are present in the peripheral bronchus supports the possibility of a local action of opioids. However, the clinical benefit of nebulized morphine is controversial. The purpose of this study was to confirm the feasibility of nebulized morphine and to evaluate its clinical benefits. ⋯ Our preliminary data confirmed the feasibility of nebulized morphine and suggested its possible clinical benefit for dyspneic patients. A randomized controlled study is warranted to exclude a placebo effect and to compare the clinical benefits of nebulized morphine with those of other methods of treatment.
