Specific Antagonism Lowers Blood Pressure

Summary:
High blood pressure is associated with an increased risk of heart attack and stroke. A new study now shows that antagonists of a receptor known as EP1 reduce hypertension in mice and rats. The authors therefore suggest that targeting the PGE2 receptor EP1 might be a viable approach to treating hypertension.

FULL STORY

High blood pressure (hypertension) is associated with an increased risk of heart attack and stroke, and the frequent use of drugs known as NSAIDs, for example to treat individuals with rheumatoid arthritis, can cause hypertension.

Exactly why NSAIDs cause hypertension is not clear because they inhibit the generation of several soluble factors (known as prostaglandins) that can affect blood pressure and the effects of inhibiting the individual receptors for prostaglandins are not known. In an attempt to address this issue researchers from Vanderbilt University Medical Center identified a novel potential target for the treatment of hypertension.

In the study, which appears online on August 16 in advance of publication in the September print issue of the Journal of Clinical Investigation, Matthew Breyer and colleagues show that inhibitors of the prostaglandin E2 receptor EP1 reduce hypertension in rats. Consistent with this, mice lacking EP1 were protected from the hypertensive effects of angiotensin II and EP1-specific agonists.

The authors therefore suggest that targeting the PGE2 receptor EP1 might be a viable approach to treating hypertension.
