Continuous subcutaneous infusion of buprenorphine for cancer pain control

Abstract

The continuous subcutaneous infusion of buprenorphine, a new approach to the relief of severe cancer pain, has been carried out using a portable infusion pump. The efficacy of this method was examined in 30 patients by visual analogue scale. An infusion rate of 4 micrograms/kg/day following intramuscular administration of 0.004 micrograms/kg gave satisfactory pain relief without serious complications. The minimum effective blood concentration was not detectable by high-performance liquid chromatography. Advantages of this therapy are its simplicity, applicability in many types of cancer, multiple sites of administration, and easier training on the part of health personnel.
