Brief Summary: This is a double -blind randomized crossover study to provide evidence for the expert advice based recommendation of the Expert Working Group of the European Association for Palliative Care EAPC that patients during treatment with IR morphine are given a double dose at bed-time that replaces the next 4-hourly dose during night In addition to the primary blinded clinical part of the study an experimental part is also included This part consists of two open study days were morphine IR is given in the same fashion as the clinical study The aim is to study whether pharmacokinetic data supports the clinical data

The use of a double-bedtime IR morphine dose is equal to regularly scheduled IR morphine every 4-hour during night in respect to pain relief during night for patients with pain caused by malignant disease
Detailed Description: PROTOCOL

Double bedtime dosing during immediate-release morphine administration to cancer patients

A randomized double-blind cross-over comparison of a double bedtime dose versus two standard doses at bedtime and at night

Introduction

Oral morphine is recommended by the World Health Organization for pain control in moderate or strong cancer pain 1 At our hospital we use the practice recommended by the Expert Working Group of the European Association for Palliative Care for introduction of strong opioids with titration with immediate-release IR morphine dosed every 4 hour until an optimal balance between analgesia and side effects is achieved After the optimal daily dose is defined slow-release SR morphine in the same total daily morphine dose is started 2 One of the features of the EPAC guidelines is that patients during treatment with IR morphine are given a double bed-time that replaces the next 4-hourly dose during night 2 The rationale behind this recommendation is that giving a double dose will prolong duration of morphine analgesia and eliminate the need for awaking the patient during night However this recommendation is based on expert opinion and not evidence from clinical studies 2 Todd et al has recently presented results that challenge this approach from a cross-over study in which the patients received either a double bedtime dose or regular doses every 4-hour 3 This study showed that patients receiving a double bedtime dose reported more pain more use of rescue medications and reported inferior sleep quality compared to patients receiving regularly scheduled doses A limitation of this study was that they did not perform the study blinded and thus consequently the results are subject to bias It is a need for a placebo-controlled study before the evidence carries enough weight to change current recommendations

Besides a clinical study it is also relevant to obtain pharmacokinetic observations during double bedtime and regularly IR morphine dosing Repeated blood sampling will disturb the patients during night and hence confound the clinical observations eg sleep quality Consequently the blood samples will not be obtained in the same dosing interval where the clinical data are obtained
