Oxymorphone Hydrochloride Extended-Release (OPANA: A Case Report®: A Case Report) Associated With Acute Kidney Injury in a Chronic Pain Patient: A Case Report
Oxymorphone hydrochloride extended-release (OPANA®) is an opioid prescribed for the treatment of moderate-to-severe chronic pain. Kidney injury related to its use has not previously been reported. We present a case of a chronic pain patient with underlying chronic renal insufficiency who developed superimposed acute kidney injury when his opioid analgesic was changed from morphine sulfate extended-release to OPANA. Electron microscopy of his renal tissue revealed lamellated podocytes typically seen with drug-induced phospholipidosis.
