Peritonsillar abscess - Do we need anaerobic cover?
1ENT Department, Christian Medical College, Ludhiana, Punjab, 141 008 India.
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.
Insights
Injectable penicillin remains the primary treatment for Peritonsillar abscess (PTA). Even with resistant bacteria, effective management is achievable through drainage, hydrogen peroxide gargles, and injectable penicillin.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Pharmacology
Background:
- Peritonsillar abscess (PTA) treatment often involves antibiotics targeting both aerobic and anaerobic organisms.
- The emergence of new, expensive antibiotics raises questions about cost-effective treatment options for PTA.
- Identifying an economical and accessible antibiotic for PTA is crucial.
Purpose of the Study:
- To evaluate the efficacy and cost-effectiveness of existing antibiotics for Peritonsillar abscess.
- To determine if current, affordable antibiotics remain suitable for treating PTA.
Main Methods:
- This study focused on the clinical context of Peritonsillar abscess treatment.
- The research assessed the common causative organisms in PTA.
- The study considered the availability and cost of various antibiotics.
Main Results:
- Group A Streptococcus (GABHS) and Staphylococcus aureus (coagulase-positive) are the most frequent pathogens in PTA.
- Injectable penicillin is identified as the preferred antibiotic for PTA.
- Penicillin-resistant organisms do not preclude effective PTA management.
Conclusions:
- Injectable penicillin is the drug of choice for Peritonsillar abscess (PTA).
- Effective PTA management is possible with abscess drainage, hydrogen peroxide gargles, and injectable penicillin, even in cases of penicillin resistance.

Three primary contributing factors have been identified.
Atypical Pneumonia
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
