By Tabitha Reuben Researchers from University College London have claimed that Statins are safe and effective for patients with liver enzyme abnormalities and they also improve the function of the liver in these patients. Dimitri P. Mikhailidis, MD, of University College London, and colleagues said in their study that liver test results in patients with moderately abnormal liver tests at baseline improved with statin treatment. "The risk-to-benefit ratio of long-term statin treatment favors statin administration even for patients with moderately abnormal liver tests," the authors wrote.
