Abstract
OBJECTIVE: To find out the usability and advantage with regard to the advent of new and more costly antibiotics. In the treatment of Peritonsillar abscess the demonstration of, both aerobic and anaerobic organisms has raised the question of possible need to treat with antibiotics effective against anaerobes. It was in this very context that this study was planned to find out if we still have an economically and easily available antibiotic to treat Peritonsillar abscess. CONCLUSIONS: Injectable penicillin is the drug of choice in PTA as GABHS and staphylococcus aureus coagulase positive are the most common organism associated with this condition. Even where penicillin resistant organism is present, effective management of the abscess is possible if it is drained well and weak hydrogen peroxide gargles are used along with injectable penicillin.
