  • Powder formulation disintegrating system and method for dry powder inhalers
    Patent 6,681,768
    Issued: January 27, 2004
    Inventor(s): Anne; Haaije de Boer & Henderik Willem; Frijlink & Doetie; Gjaltema & Joachim; Goede & Paul; Hagedoorn
    Assignee(s): Sofotec GmbH & Co. KG

    A disperser for dry powders which can be used with different dose systems, dose weights ranging from 2 to 25 mg and different types of powder formulation. In one embodiment, the disperser acts both as a de-agglomeration (disintegration; aerosolization) means and as an air classifier for especially adhesive mixtures. Only fine drug particles are emitted whereas the larger agglomerates and carrier crystals are retained by the disperser. Another embodiment enables time controlled release of carrier crystals in these mixtures. Yet another embodiment has optimized performance with spherical pellets, containing no carrier crystals. Other possible embodiments of the invention make it possible to control the total inhaler resistance and the powder deposition in the upper respiratory tract by means of the addition of a so-called sheath flow of clean air. Modifications also enable carrier retainment in the mouthpiece and elimination of the tangential flow component of the discharge cloud.

RLD A Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart.
