Coated pill carries microneedles that deliver insulin and other drugs to the lining of the small intestine.

MIT researchers have developed a capsule to deliver medications that currently have to be injected, reports Steven Reinberg for HealthDay. "This experimental pill can withstand the trip through the gastrointestinal tract," writes Reinberg. "When it gets to the small intestine, it breaks down into dissolving microneedles that attach to the intestinal wall and release the drug into the bloodstream."
