Clinical Details
Official title: Switching From Morphine to Oral Methadone Plus Acetaminophen in the Treatment of Cancer Pain: A Randomized, Double-Blind Study
Study design: Supportive Care, Randomized, Double Blind (Subject, Investigator), Placebo Control, Parallel Assignment, Safety/Efficacy Study
Primary outcome: Pain intensity and time to equianalgesic effect
Secondary outcome: Degree of nausea, vomiting, obstipation, xerostomia and drowsiness
Detailed description:
Opioids are the mainstay of moderate-to-severe cancer pain management. Although morphine is
the most commonly used, methadone has some advantages such as higher potency, lower cost and
longer administration intervals. To minimize the time necessary to achieve the equianalgesic
effect after a switching from morphine to methadone, acetaminophen was added in the
treatment.
