Area of Science:

  • Pharmaceutical Technology
  • Drug Delivery Systems
  • Materials Science

Background:

  • Ubidecarenone (CoQ10) is a vital compound with poor water solubility, limiting its bioavailability.
  • Developing effective delivery systems is crucial for enhancing the therapeutic potential of poorly soluble drugs.

Purpose of the Study:

  • To develop and characterize a nanoemulsified composite (NEC) delivery system for the water-insoluble drug ubidecarenone.
  • To evaluate the technological, stability, and biopharmaceutical properties of the NEC system.

Main Methods:

  • Incorporation of a double microemulsion into a microporous carrier to create the NEC delivery system.
  • Assessment of powder technological properties (flowability).
  • Evaluation of nano-droplet stability and drug release characteristics.

  • Measurement of water solubility and oral absorption in rats (plasma levels and AUC).

    • Main Results:

    • The NEC system demonstrated good flowability and long-term stability, maintaining nano-droplet size.
    • Water solubility of ubidecarenone was increased up to 50-fold compared to the pure drug.
    • Oral absorption in rats showed up to a three-fold increase in plasma levels and AUC compared to commercial products.

    Conclusions:

    • The patented NEC delivery system effectively improves the solubility and oral bioavailability of ubidecarenone.
    • This nanoemulsion-based approach offers a promising strategy for enhancing the delivery of poorly water-soluble drugs.
