Mechanism & Pharmacology

Simplified Explanation (Patient-Friendly)

Tetracycline is an antibiotic that fights bacteria by stopping their growth. It binds to the bacteria's ribosomes, disrupting their ability to make proteins necessary for survival. Think of it as blocking a factory's production line, preventing the bacteria from multiplying and spreading infection. It's effective against a wide range of bacteria, making it a popular choice for treating various infections, including those in the skin, lungs, and urinary tract.

Clinical Terms (Health Canada Approved Monograph References)

Pharmacologically, tetracycline is classified under the ATC code J01AA07 as a systemic tetracycline. Its mechanism of action is primarily bacteriostatic; it inhibits protein synthesis by binding to the 30S ribosomal subunit. This disrupts the translation process, ultimately preventing bacterial replication. Tetracycline exhibits a broad spectrum of activity, including efficacy against both Gram-positive and Gram-negative organisms. Due to its properties, it’s crucial to monitor for bacterial resistance and interactions with other medications, particularly those that include metal ions, as they can reduce absorption.
