Study paves way for safer medicines, sans side effects

Now one can get medicines sans the side effects, which has affected patients for years. A new technique for precisely targeting molecules within cells is paving the way for safer medicines that are free of side effects. By manipulating the molecules, scientists can determine exactly which locations to target while avoiding locations that would cause harmful side effects. "The problem with side effects is caused because you just could not distinguish the molecules doing different things in the same cell," said Zhu. Almost every drug that can treat diseases has side effects, either major or minor, but usually they always have something," he added.
