Retrospective study of the use of hydromorphone in palliative care patients with normal and abnormal urea and creatinine.
An uncontrolled retrospective study was conducted looking at the use of oral controlled-release hydromorphone in palliative care patients. Over a 2-year period 55 patients were switched to hydromorphone therapy, and the efficacy and outcomes were assessed. Urea and electrolyte measurements were also recorded at the time of opioid switch and renal impairment defined as urea > 10.5 mmol/l and/or creatinine > or = 101 mmol/l. ⋯ We conclude that hydromorphone is a flexible second-line alternative to morphine that is particularly useful when intolerable side-effects are experienced with other opioids. In renal impairment (including two patients with end-stage renal failure) we found hydromorphone to be safe and effective. Further clinical and pharmacokinetic studies are required.
