Researchers found that orally administered sevelamer — a dialysis drug — can bind off-target antibiotics, shown being injected into the arm here, in the gut. Off-target antibiotics, or antibiotics that end up in the body away from the point of infection, can contribute to bacteria evolving to develop antibiotic resistance.
