Uric Acid Shows Promise in Treating Ischemic Stroke, Study Shows

A preclinical study showed that “rodents treated with uric acid showed improved long-term outcomes after acute ischemic stroke.”

These findings suggest that “the treatment may work as an add-on therapy to standard stroke treatments in humans.” Researchers used a “well-established rodent model of stroke that closely simulates stroke in humans. They administered intravenous uric acid or saline control and monitored animals’ recovery over one month. Behavioral and neurological assessments, including MRI scans, were used to evaluate the treatment’s effects.”

Mice treated with uric acid “had better sensorimotor function—the primary outcome measure—30 days after stroke. More animals in the uric acid group also survived their stroke compared to control animals. However, some secondary outcome measures, such as brain damage, were not reduced.” Uric acid was efficacious across all of the groups of mice studied.

Ischemic stroke “occurs when a blood clot or other blockage in an artery cuts off blood supply to the brain. Strokes are treated with medications or surgery aimed to break up clots and restore blood flow to affected brain areas. These therapies are highly effective, but not all people fully recover. Using additional treatments that protect brain tissue from damage, either immediately before or during clot removal, could boost the effects of standard treatments and greatly improve recovery in patients.”
