Most bacteriostatic antibiotics work by binding to bacterial ribosomes (like the 30S or 50S subunits), which prevents the cell from creating the proteins it needs to grow.
Bacteriostats typically interfere with the internal machinery of bacterial cells rather than destroying their physical structure.
(e.g., Erythromycin, Azithromycin) common for skin and soft tissue infections. Sulfonamides: Often used for urinary tract infections.
