Zelboraf Side Effects: Diarrhea & Other Bad Side Effects. Europe’s drug regulator has approved the targeted melanoma drug Zelboraf (vemurafenib), expanding the treatment options available to nearly 160,000 people who are afflicted every year by the deadliest form of skin cancer.
The European Medicines Agency’s approval of Zelboraf follows that of the United States Food and Drug Administration given in August, and Roche Holding AG, the drug’s Swiss maker, said it expects the European Commission to endorse the approval formally in February 2012.
Artificial Food Color Side Effects: Hyperactivity, ADD, & Cancer? A United States food watchdog group is urging the government — particularly the Food and Drug Administration (FDA) to require manufacturers to disclose the use of artificial colors fully and clearly in the front labels of their food products.
Michael F. Jacobson, executive director of the Center for Science in the Public Interest, said that many food products—often marketed to appeal to children—use dangerous food dyes that can cause hyperactivity and behavioral problems.
Ecstasy Side Effects: Long-term Serotonin Loss? Recreational use of Ecstasy, the illegal party drug that produces feelings of euphoria, emotional warmth and connectedness, may cause long-term serotonin loss and other chronic changes in the human brain, scientists say.
“Our study provides some of the strongest evidence to date that the drug causes chronic loss of serotonin in humans,” said Ronald Cowan, MD, PhD, associate professor of psychiatry who led researchers at the Vanderbilt University. Their findings are reported online in the Archives of General Psychiatry.
The neurotransmitter serotonin plays critical roles in regulating mood, appetite, sleep, learning and memory and medical experts believe that low levels are associated with depression.
