Thiazide diuretics for the treatment of high blood pressure

Thiazide diuretics are a class of drugs commonly recommended as first‐line treatment for raised blood pressure because they significantly reduce death, stroke and heart attacks. This class includes bendrofluazide, chlorthalidone, cyclopenthiazide, hydrochlorothiazide, indapamide and metolazone. We asked by how much does this class of drugs lower blood pressure and whether there is a difference between individual drugs within the class. We searched the available scientific literature to find all the trials that had assessed this question. The data included in this review was up to date as of February 2014.

The aim of this guideline is to provide guidance to the NHS on the diagnosis and management of acute heart failure.
