✔️ Uses of Acos 500mg Tablet

• Treatment of Bacterial Infections

✔️ How does Acos 500mg Tablet work?

Acos 500mg Tablet is a bacteriostatic drug, which means it slows down or inhibits the growth and reproduction of bacteria. It achieves this by binding to the 50S ribosomal subunits of susceptible microorganisms, thereby interfering with protein synthesis. This disruption in protein synthesis impairs the ability of the bacteria to function and reproduce effectively, leading to their inhibition and eventual elimination by the body's immune system.
