Abstract

BACKGROUND/AIMS
OROS hydromorphone is a synthetic opioid agent. While clinical studies have tested its effectiveness at controlling cancer-associated pain in patients who have received other strong opioids, no clinical studies have tested its effectiveness at managing cancer pain in strong opioid-naive patients. We performed the present study to evaluate the efficacy and tolerability of OROS hydromorphone in strong opioid-naive cancer patients.
METHODS
We administered OROS hydromorphone to patients who had not received strong opioids during the previous month. The starting dose was 8 mg/day. The dose was increased every 2 days in patients who experienced more than four episodes of breakthrough pain per day (more than four times in patients being treated with short-acting opioids). We evaluated the efficacy, safety and tolerability of ORS hydromorphone. We also evaluated patient satisfaction and investigators' global assessments.
RESULTS
We enrolled 23 patients to the study. The decrease in the numeric rating scale (NRS) was 59%. NRS variation had decreased markedly during the previous 24 h. All patients achieved stable pain control. The side effects were similar to those of other strong opioids. In total, 26% of patients were very satisfied with the treatment and 47% satisfied, and 74% of the investigators deemed OROS hydromorphone to be very effective or effective at controlling cancer pain.
CONCLUSIONS
OROS hydromorphone is an osmotically driven, controlled-release preparation that is very effective and safe when administered once daily to strong opioid-naive cancer patients.
