Experience with an extended-release opioid formulation designed to reduce abuse liability in a community-based pain management clinic

CONTEXT: With the growing public health concern over rising rates of opioid abuse, physicians have a responsibility to incorporate safeguards into their practice to minimize the potential for opioid misuse, abuse, and diversion. Patient-specific treatment regimens should include steps to monitor treatment success with regard to optimal pain management as well as inappropriate use of opioids and other substances. Opioid formulations designed to be less attractive for abuse are also being developed. While future studies are needed to determine the impact of such formulations in addressing the issue of opioid misuse in the community as a whole, the experience of practitioners who have utilized these formulations can highlight the practical steps to incorporate such formulations into the everyday patient-care setting. PURPOSE: The purpose of this report is to describe experience in managing patients with chronic, moderate-to-severe pain using morphine sulfate and naltrexone hydrochloride extended release capsules (MS-sNT) (EMBEDA(®), King Pharmaceuticals(®) Inc, Bristol, TN, which was acquired by Pfizer Inc, New York, NY, in March 2011), a formulation designed with features to deter abuse/misuse, in a community-based pain management clinic. CASE PRESENTATIONS: Case reports demonstrating a clinical management plan for assessment, initial interview procedures, explanation/discussion of proposed therapies, patients’ treatment goals, conversion to MS-sNT, and titration and treatment outcomes are provided. RESULTS: The management approach yielded successful outcomes including pain relief, improved quality of life, treatment satisfaction, and patient acceptance of a formulation designed to deter abuse/misuse. DISCUSSION: The cases presented demonstrate that the communication accompanying complete pretreatment assessment, goal-setting and expectations, and attention to individual patient needs can enable optimization of pain-related outcomes, resulting in improved quality of life for patients and fostering patient acceptance of formulations designed to help address opioid abuse/misuse issues in the community at large.
