Oral and IV Baclofen in Adult Volunteers

• Status: Completed
• Trial end date: 2014-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of this study is to characterize baclofen pharmacokinetics following oral and intravenous administration in patients who are on chronic oral baclofen therapy. The secondary objective is to determine the safety profile of an IV baclofen formulation.

This study is a randomized crossover study with two treatment arms. All subjects will receive a dose of oral baclofen and a dose of IV baclofen on separate study days. Whether the oral or intravenous form is given on the first study day will be randomized in a 1:1 manner.

The pharmacokinetic and tolerability information gained from this study will support the development of further studies to assess the use of IV baclofen to prevent or treat baclofen withdrawal syndrome.
