Abstract
Stable oral preparations of 16-membered ring macrolide antibiotics such as SF-837, josamycin, 3'-propionyljosamycin, by incorporating stabilizers showing pH 3-10 in an aqueous medium, such as glycine, and dissolution accelerators showing pH 2.5-4 in an aqueous medium such as citric acid or tartaric acid. Coating such dissolution accelerators with a film-forming substance is useful to enhance the stability of the oral preparation of such antibiotics.
