Randomized Controlled Trial Clinical Trial
The effects of morphine on dyspnea and ventilatory function in elderly patients with advanced cancer: a randomized double-blind controlled trial.

This study was undertaken to assess the efficacy of morphine on dyspnea and its safety for ventilatory function in elderly advanced cancer patients. ⋯ Morphine appears effective for cancer dyspnea, and it does not compromise respiratory function at the dose level used.
