(WTVR) — The next time you have a headache, reaching for an aspirin may not help.
A new study out of the University of Pennsylvania found the coating on many tablets may reduce the drug’s effectiveness. And not just for headaches.
In fact, the protective coating may also lower the drug’s effectiveness to reduce your risk for a heart attack or stroke.
Researchers believe something in that coating may actually keep the drug from being absorbed into the body.
