This study is currently recruiting participants.

Verified by Kaunas University of Medicine, February 2008

Sponsors and Collaborators:	Kaunas University of Medicine University Hospital, Linkoeping
Information provided by:	Kaunas University of Medicine
ClinicalTrials.gov Identifier:	NCT00631501

Purpose

Matrix metalloproteinases are involved in the pathogenesis of tendinopathy. Doxycycline, a widely available pharmaceutical agent mostly used for its antibiotic properties, also functions as an inhibitor of MMPs.

This study aims to investigate the effect of doxycycline treatment on lateral epicondylalgia (tennis elbow). During three weeks, patients receive doxycycline tablets 100 mg twice daily, or placebo. Main outcome variable is pain (VAS) at three weeks.

Serum and/or plasma levels of matrix metalloproteinases and tissue inhibitors of metalloproteinases are measured.
