About

Background: Among palliative-care patients, subcutaneous route is often an alternative to intravenous route yet pharmacological and clinical data are lacking. Many French palliative crew are now using empirically paracetamol by subcutaneous route also there is no data to support this practice. The aim of the present study is to compare pharmacokinetics parameters between intravenous and subcutaneous route for palliative-care patients.

Methods/design: A randomized, open, crossover, bicenter study in two palliative care centers. The aim is to demonstrate the pharmacokinetic equivalence between the two routes of administration. Data analysis will be performed by Wilcoxn's signed Rank Test with an alpha risk of 5 percent. All adverse events will be reported for a safety analysis.

Discussion: This trial may permit, if a pharmacokinetic equivalence is established, to build randomized controlled trials to then assess the efficacy and tolerability of subcutaneous paracetamol administration.

Enrollment: 20 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
