Partial Oral Antibiotic Treatment for Bacterial Brain Abscess

Patients will be treated with an oral antibiotic regimen (e.g. amoxicillin + metronidazole) based upon pharmacokinetic and pharmacodynamic properties of the drugs, pathogen susceptibility, and any existing drug allergies or interactions

Patients will continue standard intravenous antibiotic therapy for brain abscess (e.g. 3rd generation cephalosporin + metronidazole) according to international guidelines and pathogen susceptibility patterns.
