Drug Combination Reduces Cardiovascular Complications

WRITTEN BY: Nouran Amin

According to a new study, combining the drugs hydroxychloroquine (HCQ) and azithromycin (AZM) was shown to reduce cardiovascular complications and overall mortality rate.

"Hydroxychloroquine, both alone and in combination with azithromycin, gained strong consideration as a potential COVID treatment without a large-scale study of its overall safety profile," said Daniel Prieto-Alhambra, PhD, co-senior author on this study. "We had access to an unprecedented amount of data on this drug, and we were relieved to find no worrying side effects in the short-term use of hydroxychloroquine. However, when prescribed in combination with azithromycin, it may induce heart failure and cardiovascular mortality and we would urge caution in using the two together."

Findings were published in Lancet Rheumatology.

"At medical school we were taught to 'first do no harm' and to me, our study focuses on this core belief of modern medicine," said Jennifer Lane, MD, who served as co-lead author on this study along with Jamie Weaver. "OHDSI has the power to investigate this question in a very thorough way and to go through rigorous steps. We are looking at patients from the general population, which is why it is so important to look at data from multiple countries. There are reasons why you may get bias from one data source, but if we find a signal in the Netherlands, and we find it in Spain, and we find it in the U.S., then we know we have something."
