  • Publication number: 20040234594
    Abstract: A new oral pharmaceutical dosage form comprising a core material that contains a proton pump inhibitor, one or more alkaline reacting compounds and optionally pharmaceutical excipients having a water soluble separating layer and an enteric coating layer. The core material as such is alkaline reacting and the separating layer between the alkaline reacting core material and the enteric coating layer is formed in situ as a water soluble salt between the alkaline reacting compound(s) and the enteric coating polymer. The invention also describes a new efficient process for the manufacture of such a dosage form comprising two functionally different layers in one manufacturing step, and its use in medicine.

  • Patent number: 6610323
    Abstract: An enteric coated pharmaceutical dosage form comprising an H+,K+-ATPase inhibitor is disclosed. The dosage form comprises at least two portions of the H+,K+- ATPase inhibitor to be released in at least two consecutive pulses. The dosage form has at least one fraction with a pulsed delayed release and another fraction with instant release of the H+,K+-ATPase inhibitor. The portions are released in time by from 0.5 and up to 12 hours interval, preferably by from 0.5 and up to 8 hours, and more preferably by from 0.5 and up to 4 hours interval. The dosage form is intended for once daily administration.
