Quizplus · Accepted Answer

Penicillin is known to be ineffective in treating infections inside the brain, as it cannot cross the blood-brain barrier. Therefore, it can only be used for infections outside the brain. Sulfamide, clarithromycin, and azithromycin are also antibiotics but they do not have the same limitation as penicillin and can be used for infections both inside and outside the brain.
