Nanoemulsion has the potential to overcome several disadvantages in drug formulation. Nanoemulsions are nano-sized emulsions that can improve the bioavailability of drug molecules via various routes of administration. The development of nanoemulsion formulation is a challenging and lengthy process. Selecting components such as oil phase, surfactant, an optimum oil-to-surfactant ratio, and ideal process parameters are critical for developing a stable nanoemulsion. Development becomes more complicated when a drug molecule is sensitive to a variety of factors. This webinar discusses, with a case study, a nanoemulsion development process using a microfluidizer, and factors to consider while developing a sterile ophthalmic nanoemulsion formulation for a light, oxidation, and heat-sensitive molecule.
