Tapentadol in the management of cancer pain: current evidence and future perspectives.



Thanks to the progress in early diagnosis and treatment of cancer, the life expectancy of cancer patients has now increased. Patients are, therefore, more likely to experience their individual cancer pain as a chronic pain. As a consequence, long-term treatment of cancer-related pain and oncological therapy-related pain are a major need for all patients and a challenge to all healthcare professionals. Tapentadol is a centrally acting analgesic drug characterized by two synergistic mechanisms of action, since it acts at the µ-opioid receptor (MOR) and inhibits noradrenalin re-uptake (NRI). Therefore, tapentadol has been considered the first of a new class of drugs, MOR-NRI. Tapentadol has been tested in different populations of cancer patients (opioid-naive and -pretreated), such as those with pain of mixed etiology, patients with pain from hematological malignancies and patients experiencing pain conditions due to anticancer treatment. According to available evidence, tapentadol prolonged release was well tolerated and effective in cancer pain patients. In randomized, double-blind and active-controlled trials it proved non-inferior to standard opioids like morphine or oxycodone in the management of moderate-to-severe cancer pain, both in opioid-naive and in opioid-pretreated patients. The good analgesic efficacy may be partly due to the action of tapentadol on neuropathic pain components. Together with the low rate of gastrointestinal adverse effects and the overall favorable safety profile, tapentadol can be considered a good option in cancer pain patients, who can suffer frequently from nausea, vomiting, constipation or other events that further reduce their quality of life.
