Mechanism & Pharmacology

Tetracycline works through its unique mechanism to impede bacterial growth.

Simplified explanation

This antibiotic halts bacterial growth by targeting protein synthesis. By binding to the ribosomal subunits, it inhibits the translation process, effectively preventing bacteria from multiplying. This action is pivotal, making tetracycline a reliable choice for various infections such as acne, respiratory conditions, and more.

Clinical terms

As a broad-spectrum antibiotic, tetracycline is effective against both Gram-positive and Gram-negative organisms. It is often utilised in cases where other antibiotics have failed. Classified under the ATC code J01AA07, it is listed as a systemic tetracycline, reflecting its wide application in treating bacterial infections.

Indications & Off-Label Uses

Tetracycline is primarily approved for specific medical indications but can also have off-label uses.

Approved indications by TGA

The Therapeutic Goods Administration (TGA) in Australia endorses tetracycline for treating conditions like acne vulgaris, respiratory tract infections, and urinary tract infections. These approvals are integral for healthcare providers in treating their patients effectively.

Off-label uses in Australian clinical practice

Beyond the approved uses, tetracycline is occasionally prescribed off-label for conditions such as Lyme disease and certain chronic inflammatory disorders. Its anti-inflammatory properties play a crucial role in managing these conditions, showcasing its versatility as a medication.

Key Clinical Findings

Recent studies provide valuable insights into tetracycline's effectiveness and emerging trends in its use.

Research conducted in Australia from 2022 to 2025 highlights tetracycline's continual relevance in managing acne and respiratory infections amidst rising concerns of antibiotic resistance. Findings stress the importance of proper prescribing practices to curtail developing resistance while optimising patient outcomes, ensuring tetracycline remains a go-to option for healthcare professionals.
