    Area of Science:

    • Pharmacology
    • Drug Delivery Systems
    • Materials Science

    Background:

    • Controlled-release formulations improve drug efficacy, safety, and duration by regulating drug release.
    • Traditional oral drug delivery can be affected by gastrointestinal variability.
    • Indomethacin is a widely used anti-inflammatory drug.

    Purpose of the Study:

    • To evaluate the performance of 'Osmosin', a novel oral precision-release formulation of sodium indomethacin trihydrate.
    • To assess the predictability and control of drug release from the osmotic system.
    • To compare the release profile of 'Osmosin' with conventional indomethacin formulations.

    Main Methods:

    • Development of a novel osmotic system for oral administration of sodium indomethacin trihydrate.
    • In vitro testing to evaluate drug release kinetics.
    • In vivo studies to assess predictability and compare with conventional forms.
    • Analysis of drug release independence from gastrointestinal pH and motility.

    Main Results:

    • 'Osmosin' demonstrated precise drug release at a predetermined rate into the gastrointestinal lumen.
    • Drug dissolution was programmed by the formulation, independent of gastrointestinal variables.
    • In vitro testing showed a high degree of in vivo predictability.
    • Comparisons revealed 'Osmosin' provided more sustained and constant drug release profiles than conventional forms.

    Conclusions:

    • 'Osmosin' represents a significant advancement in oral controlled-release technology.
    • The osmotic system offers predictable and programmable drug release, enhancing indomethacin therapy.
    • This precision-release system is particularly well-suited for drugs like indomethacin, optimizing their therapeutic potential.
