Abstract
Background and Goal of Study: The management of moderate/severe cancer pain with opiates implies an essential stage of initial titration.(1) Literature provides no univocal guidelines for such stage; the use of immediate release morphine sulphate, administered every 4 hours with the double dose at night (2) is awkward because of management, pharmacokinetic and patients' compliance limitations. Aim of this study was to verify the effectiveness and applicability of a titration approach based on the administration of a combination of sustained release (SR) opiate and an immediate release (IR) opiate as rescue dose. Materials and Methods: In this observational and retrospective study (hospital ethic committee notified) were included 98 consecutive inpatients with moderate/severe cancer pain (NRS>4), followed by the hospital pain management service in 2008-2009. Opiate titration in these patients consisted of the administration of oxycodone SR (OS-SR ≥ 5mg) twice a day and morphine IR (MS-IR, 30% daily dose of OS-SR) administered as 'rescue dose', maximum four times daily. Measures: socio-demographic characteristics, initial OS-SR dose, initial MS-IR dose, initial and post-treatment pain scores, (NRSs, under static and NRSd, dynamic- conditions), number of rescue doses administered in the 24h, variations of OS-SR dose and side effects.
