Mechanism of Action
A semi-synthetic antibiotic acts on extracellular pathogens. It is active against mycoplasmas, ureaplasmas, endobacteria and some other microorganisms. The mechanism of antimicrobial action is associated with a violation of the structure of the protein in bacterial cells. Because of this, their growth and reproduction slow down.

If the treatment schedule is not more than three days, then capsules of 500 mg are usually prescribed.
