    Patent number: 5051262
    Abstract: Specifically, the present invention relates to processes for preparing delayed action galenic forms. The process is characterized in that the application solutions of excipients, coatings and active constituents are adjusted to a desired pH. The independence of the rate of dissolution of a controlled release or sustained action oral pharmaceutical form is increased by admixing a pH adjusting agent with every application solution of medicament, excipeint or coating, throughout the course of formulation of the pharmaceutical form.
