CLINICAL TRIALS PROFILE FOR TERAZOSIN HYDROCHLORIDE

All Clinical Trials for TERAZOSIN HYDROCHLORIDE

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00007592 ↗	Hypertension Screening and Treatment Program	Completed	US Department of Veterans Affairs		1989-06-01	Hypertension is one of the most common medical problems in the United States and in the VA health care system. It has been well-documented that hypertension can be effectively treated. However, there remain important unresolved clinical questions in the area of antihypertensive treatment. For example, how much is mortality affected by visit compliance, blood pressure control and type of antihypertensive agent? Or, are some regimens associated with more morbidity than others? Or, are there inexpensive regimens that are as effective as more expensive regimens? The amount of data that is available from this demonstration project (currently 6,100 patients) will help address these questions. The answers to these questions should result in better care for veterans with hypertension.
