The role of tramadol in cancer pain treatment--a review.
In most cancer patients pain can be successfully treated with pharmacological measures using opioid analgesics alone or in combination with adjuvant analgesics (coanalgesics). Weak opioids are usually recommended in the treatment of moderate cancer pain. There is still a debate as to whether the second step of the WHO analgesic ladder comprising opioid analgesics such as tramadol, codeine, dihydrocodeine, and dextropropoxyphene is still needed for the treatment of cancer pain. On the basis of our experience and review of the literature we think that there is definitely a place for weak opioids in the treatment of moderate cancer pain. One of the most interesting and useful weak opioids is tramadol (Adolonta, Contramal, Nobligan, Top-Algic, Tramal, Tramal Long, Tramal Retard, Tramundin, Trodon, Ultram, Zydol). Its unique mechanism of action, analgesic efficacy and profile of adverse reactions have been the reason of performing many experimental and clinical studies with tramadol. In this article we summarize data on pharmacology, mechanisms of action, pharmacokinetics, side effects and clinical experience assessing analgesic efficacy, adverse reactions and safety of tramadol in cancer pain.
