Start date October 2012
End date December 2012
Trial size 3000 participants
Trial identifier NCT01758263, NEB-HE-200


This is a retrospective data analysis of patients with high blood pressure (hypertension) who took metoprolol for a minimum of 6 months who then switched to taking nebivolol for a minimum of 6 month to treat hypertension. These patients will be identified from a large medical claims database. This study tests the hypothesis (alternative, higher or lower) that average patient monthly health care administrative cost changes after switching from metoprolol to nebivolol.
