SCIENTISTS have shown for the first time a link between two types of heart problems and one of the most commonly prescribed classes of antibiotics.
In a study published recently in the Journal of the American College of Cardiology, researchers at the University of British Columbia (UBC) in partnership with the Provincial Health Services Authority’s (PHSA) Therapeutic Evaluation Unit found that current users of fluoroquinolone antibiotics, such as Ciprofloxacin or Cipro, face a 2.4 times greater risk of developing aortic and mitral regurgitation, where the blood backflows into the heart, compared to patients who take amoxicillin, a different type of antibiotic. The greatest risk is within 30 days of use.
Recent studies have also linked the same class of antibiotics to other heart problems. Some physicians favour fluoroquinolones over other antibiotics for their broad spectrum of antibacterial activity and high oral absorption, which is as effective as intravenous, or IV, treatment.
The researchers hope their study helps inform the public and physicians that if patients present with cardiac issues, where no other cause has been discovered, fluoroquinolone antibiotics could potentially be a cause.
