Question

Why must vancomycin be administered intravenously except when used to treat intestinal infections?

Quizplus · Accepted Answer

Vancomycin is poorly absorbed from the intestinal tract, which means that oral administration would not result in effective concentrations of the drug in the bloodstream. Intravenous administration allows for more precise dosing and ensures that the drug reaches effective concentrations in the bloodstream. However, in the case of treating intestinal infections, oral administration may be effective because the drug can be delivered directly to the site of the infection.
