The eye is the specialized part of the body and is comprised of numerous physiological
ocular barriers that limit the drug absorption at the action site. Regardless of various efforts …

This review describes the principles of formation and stability of nano-emulsions. It starts
with an introduction highlighting the main advantages of nano-emulsions over …

Nanoemulsions are kinetically stable biphasic dispersion of two immiscible liquids typically
stabilized by an emulsifier with droplet sizes in the range of 10–200 nm. Present work deals …

Presenting breakthrough research pertinent to scientists in a wide range of disciplines-from
medicine and biotechnology to cosmetics and pharmacy-this Second Edition provides …

Various efforts in ocular drug delivery have been made to improve the bioavailability and to
prolong the residence time of drugs applied topically onto the eye. The potential use of …

The droplet size distribution of an emulsion governs emulsion properties such as long-term
stability, texture and optical appearance. Consequently, means to control the droplet size …

The characterisation of pharmaceutical formulations by microscopic techniques is essential
to obtain reliable data about the actual morphology of the system. Since the size range of …

Formation of nano-emulsions has been studied in the system water/Brij 30/decane at 25° C
by three low-energy emulsification methods:(A) stepwise addition of oil to a water …

Microemulsions are thermodynamically stable, transparent, low viscosity, and isotropic
dispersions consisting of oil and water stabilized by an interfacial film of surfactant …

Eye drops are the most used dosage form by ocular route, in spite of low bioavailability and
the pulsed release of the drug. However, due to their intrinsic properties and specific …
