Basic pellets containing erythromycin base, to which a small amount of a slightly acid salt, such as potassium dihydrogen phosphate and possibly an additive is added for improved release of the active substance in the intestinal tract, are provided with a coating that contains a polymer resistant to gastric juice, such as poly(methacrylic acid, -ethylacrylate), a separating agent, such as talc, and a softening agent, such as diethyl phthalate.
