A New Use for Statins: Asthma

Statins continue to show that their benefits extend beyond their original focus of lowering high cholesterol. With the increasing prevalence of asthma, scientists are studying the effects of statins in the lungs. In a new study in Physiological Reports, a team of researchers from the University of California, Davis, has demonstrated the feasibility of using statins to treat asthma.

According to the researchers, while a number of studies have supported that statins may be an effective asthma therapy, this new study addresses one of the obstacles in translating the findings into patient use: how to deliver the drug. Because statins are only approved to be taken orally, earlier studies administered the drug to the whole body to study its effects on the lungs. However, it was unclear how the drug was working through the lungs or even if it got there, the researchers wrote. For patient use, direct delivery would be more effective because it lowers the dose needed and reduces the risk of side effects.

In this study, the research team tested whether inhaled statins would alleviate asthma symptoms in mice. Using a new method they developed to measure statin levels, the researchers found that as a spray, the drug went mostly to the lungs, with little going to the rest of the body, and was not toxic. The statin treatment lowered the airway’s over-sensitivity to allergens, had modest anti-inflammatory effects and reduced overproduction of mucus. The optimal statin type and dose still need to be determined, the researchers wrote, but “our results indicate that the statins should be explored as a novel class of inhaler therapy for airway diseases such as asthma.”

The article “Intratracheal instillation of pravastatin for the treatment of murine allergic asthma: a lung-targeted approach to deliver statins” is published in the May issue of Physiological Reports, a joint journal of the Physiological Society and the American Physiological Society.

New Research Shows Why Statins Should Be Viewed as a Double-Edged Sword

Released August 13, 2015 - Statins have significant cardiovascular benefits, but also serious side effects. A new study finds that statin use impairs stem cell function, which helps in slowing atherosclerosis but hinders other body processes. Because of these effects, the study supports weighing individual risk when considering statins as a preventive measure.

Statins May Provide Treatment Alternative for Chronic Liver Disease

Released March 23, 2017 - Statin drugs are widely used to manage high cholesterol and reduce the risk of cardiovascular disease. But in a new review of more than 50 studies, researchers cite reductions in liver inflammation and improvements in other related factors as reasons why statins make good candidates for treating chronic liver disease. The article is published ahead of print in the American Journal of Physiology—Gastrointestinal and Liver Physiology.

High-Fat Diet during Pregnancy Compromises Offspring’s Lung Health

Released March 29, 2017 - Women who follow a high-fat diet during pregnancy may increase their children’s risk for asthma. A mouse study by Oregon Health and Science University researchers suggests that consistent consumption of fat-laden foods may change the immune response of the offsprings’ respiratory system. The article is published in Physiological Reports.
