    Researchers explored various fenoprofen salts to find the best oral dosage form. Stability and compatibility studies, including analysis of photodegradation, were conducted to ensure formulation safety and efficacy.

    Area of Science:

    • Pharmaceutical Sciences
    • Drug Formulation
    • Analytical Chemistry

    Background:

    • Fenoprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief.
    • Optimizing oral dosage formulations is crucial for drug efficacy and patient compliance.
    • Understanding salt forms and their stability impacts drug product development.

    Purpose of the Study:

    • To prepare and characterize various fenoprofen salts for oral dosage formulation.
    • To evaluate the stability of water of hydration in different fenoprofen salt forms.
    • To assess the compatibility of fenoprofen salts with propoxyphene and codeine salts and identify photodegradation products.

    Main Methods:

    • Preparation and characterization of multiple fenoprofen salts.
    • Thermal analysis techniques (e.g., DSC, TGA) to assess hydration stability.

  • Compatibility studies with other drug salts and photodegradation analysis.

    • Main Results:

    • Different fenoprofen salt forms exhibited varying stabilities of water of hydration.
    • The presence of water of hydration influenced the compatibility of fenoprofen salts with propoxyphene and codeine.
    • Key photodegradation products were identified, providing insights into potential formulation challenges.

    Conclusions:

    • The choice of fenoprofen salt form significantly impacts hydration stability and drug compatibility.
    • Thermal analysis is a valuable tool for assessing drug-excipient interactions and formulation stability.
    • Identification of photodegradation products is essential for developing stable and safe fenoprofen oral formulations.
