Mechanism & Pharmacology

Simplified explanation

Erythromycin works by inhibiting bacterial protein synthesis, effectively stopping the growth of various bacteria responsible for infections. As a macrolide antibiotic, it binds to the ribosomal subunits in bacteria, preventing them from producing proteins vital for their survival and replication. This mechanism helps clear infections such as respiratory tract infections, skin infections, and more.

Furthermore, erythromycin can also exhibit anti-inflammatory properties, which can be particularly beneficial in treating acne.

Clinical terms

Understanding some clinical terminology related to erythromycin can enhance comprehension of its pharmacological actions:

• Bacteriostatic: Refers to substances that inhibit bacterial growth.
• Macrolide antibiotics: A class of antibiotics that erythromycin belongs to, distinguished by their macrocyclic lactone structure.
• Pharmacokinetics: The study of how the body absorbs, distributes, metabolises, and excretes drugs like erythromycin.

Indications & Off-Label Uses

Approved indications by TGA

In Australia, erythromycin holds TGA approval for various conditions. It is commonly prescribed for:

• Respiratory infections such as bronchitis and pneumonia.
• Skin and soft tissue infections, including acne.
• Ophthalmic infections as a topical eye ointment.

Due to its effectiveness, it remains a trusted option in treating these ailments, highlighting erythromycin's versatility.

Off-label uses in Australian clinical practice

Beyond its approved indications, erythromycin is often utilised off-label in Australian clinical settings. For example:

• It has been observed as a gastroprokinetic agent, aiding patients with gastroparesis.
• Some practitioners prescribe erythromycin for perioral dermatitis due to its anti-inflammatory effects.

This off-label usage underscores erythromycin's adaptability in a clinical context and its benefits beyond traditional treatment boundaries.

Key Clinical Findings

Recent findings from studies conducted between 2022 and 2025 further solidify erythromycin's role in antibacterial therapy. Notable research, both in Australia and internationally, highlights its:

• Effectiveness against emerging antibiotic-resistant bacteria.
