Improving topical drug delivery

Alfa’s partner, Gattefossé, provides innovative, safe and cost effective excipients for the development creams, lotions, gels and microemulsions.

These excipients help combine pharmaceutical quality, therapeutic efficacy and consumer acceptability into distinct topical formulations designed to:

  • Improve drug delivery
  • Emulsify poorly soluble drugs
  • Improve product stability
  • Improve product aesthetics and feel
  • Improve process parameters
  • Reduce manufacturing costs

Microemulsions

Because of their particular microstructure, microemulsions offer well-known pharmaceutical benefits, including:

  • Optimized solubilisation capacity
  • Improved active drug efficacy drug depot or systemic effect
  • Considerably simpler manufacturing process

Gattefossé provides the components and the expertise to formulate microemulsions Surfactants, Co-surfactants, Oily Phase.
