The study appears in the January issue of Kidney International.
When Viagra was introduced in 1999, the drug’s manufacturer warned of a number of visual side effects, including possible nerve damage to the eyes. But a California study rules out some of these risks — even when the drug is taken in high doses. According to Dr. Tim McCulley, assistant professor of ophthalmology at the University of California at Irvine, blood flow in the eye does not seem to be reduced by even high doses of the popular erectile dysfunction drug. Since Viagra lowers blood pressure overall, there was persistent suspicion that the drug might cause decreased optical blood flow, which can cause nerve damage.
The phrase “no pain, no gain,” used by coaches to prod school-age athletes, may have more meaning than they ever imagined, two studies have found. The studies appear in the October issues of Pediatrics and Pediatric Research and suggest new ways to mark the boundary between healthy and unhealthy exercise. The research also may help physicians and others develop optimal levels of exercise that may help stave off the current epidemic of obesity in adults and children.
