Unlike erythromycin,<unk>  is acid-stable, so can be taken orally without having to be protected from gastric acids. It is readily absorbed, and diffuses into most tissues and phagocytes. Due to the high concentration in phagocytes,<unk>  is actively transported to the site of infection. During active phagocytosis, large concentrations of<unk>  are released; its concentration in the tissues can be over 10 times higher than in plasma. Highest concentrations are found in liver, lung tissue, and stool.
