Tetracyclines function primarily as which type of antibiotic?

Tetracyclines are classified primarily as bacteriostatic antibiotics. This means they inhibit the growth and reproduction of bacteria rather than killing them outright. By interfering with protein synthesis, tetracyclines prevent bacteria from producing essential proteins needed for their growth and replication. This action allows the immune system to effectively clear the infection over time.

While tetracyclines are broad-spectrum, targeting a wide range of both gram-positive and gram-negative bacteria, the defining characteristic that sets them apart is their bacteriostatic action. Additionally, although they inhibit protein synthesis, this description is more about their mechanism rather than their primary classification as an antibiotic type. Thus, the focus on their bacteriostatic effect captures the core of how they function in antibacterial therapy.
