title: Opioid titration in cancer pain: a critical review.
abstract: Initiation of therapy with strong opioids is a challenging phase to obtain the maximum benefit and to gain the patient's compliance. The approach could be different, depending on the clinical situation and type of opioid regimen. Substantially, the need to titrate the dose of strong opioids emerges in different conditions: (a) in opioid-naive patients who require an opioid treatment; (b) in patients no longer responsive to weaker drugs requiring strong opioids; (c) in patients already receiving strong opioids requiring higher doses because of an increase in pain intensity or a new acute pain problem; (d) in patients who are severely suffering and need an intensive as well as rapid intervention, due to previous persistent undertreatment. Whilst there is a vast literature confirming the effectiveness of most opioid drugs for the treatment of chronic pain, there is a lack of information regarding opioid titration. This review assesses the principal titration methods and outcomes regarding the different opioid drugs and their modalities of administration, in different clinical contexts.
