Common Antibiotic Ciprofloxacin May Offer New Hope for Blood Pressure Control

Researchers from the University of Bath (UK) and the University of Cape Town (South Africa) have uncovered a remarkable new potential for the widely used antibiotic ciprofloxacin: it may help manage high blood pressure. The international team, led by Professor Ravi Acharya and Professor Ed Sturrock, discovered that ciprofloxacin blocks the Angiotensin-Converting Enzyme (ACE), a key regulator in blood pressure control, but does so in a novel way compared to existing ACE inhibitor medications.

High blood pressure affects about one in three adults in the UK, with millions relying on ACE inhibitors to keep their blood pressure in check. These current medications work by blocking ACE, which normally converts angiotensin I to angiotensin II—a process that narrows blood vessels and raises blood pressure. However, ACE is also involved in many other bodily functions, which is why existing drugs can cause side effects like coughing or throat swelling.

Ciprofloxacin, however, inhibits ACE through a different mechanism, potentially offering a new avenue for drug development with fewer side effects. The discovery could pave the way for a new family of blood pressure medications that are both more effective and better tolerated by patients.

Professor Acharya emphasized the importance of this finding, noting that while ciprofloxacin itself is not being recommended as a new blood pressure treatment at this stage, its unique action provides a blueprint for developing improved therapies for cardiovascular disease.
