    Abstract: A diffusion cell for use in determining the absorption rate of a study substance through a permeable membrane. The cell includes a receptor chamber which contains receptor fluid to receive study substance absorbed through the membrane. The receptor chamber includes a fluid inlet and a fluid outlet. A rotary stirrer is situated adjacent the fluid outlet. The stirrer is rotated so as to rotate the receptor fluid in the receptor chamber in such manner that the fluid pressure is greater at the outlet than at the inlet, so that the stirrer defines a pump which pumps receptor fluid outwardly through the outlet, then through a detector, and then back into the receptor chamber through the inlet. The detector determines the concentration of study substance within the receptor fluid.

    Abstract: A method and drug form are provided for increasing the oral absorption of glycosidic and related antibiotics such as macrolide, aminoglycoside, lincomycin and anthracycline antibiotics and related chemical species by the oral administration of said glycosidic and related antibiotics in a suitable pharmaceutically accepted excipient to which has been added a hydroxyaryl or hydroxyaralkyl acid or salt thereof. The hydroxyaryl or hydroxyaralkyl acid or salt thereof is present in the drug form in quantities sufficient to be effective in enhancing the rate of oral absorption of glycosidic and related antibiotic.
