Abstract Local delivery of drugs and biopharmaceuticals for the treatment of inflammatory bowel disease remains a challenge. Innovative nanomedicines with appropriate properties raise the possibility of efficient drug targeting. Hence, the overall aim of this study was to develop and characterize a protamine-based nanosystem for topical delivery of therapeutics to inflamed intestinal mucosa following oral administration. Protamine nanocapsules with a new composition were for the first time...

The purpose of this investigation was to prepare and characterize acyclovir loaded floating microspheres by emulsification solvent evaporation method. Piperine was added to investigate its effect on acyclovir bioavailability. The microspheres were characterized for size, shape, entrapment efficiency, in vitro drug release, and in vivo pharmacokinetic parameters. The morphological characterization of microspheres was done using a scanning electron microscope. The microspheres were spherical and...

There is lot of confusion in the literatures regarding the method of production of nanoemulsion. According to some authors, only the methods using high energy like high-pressure microfluidizer or high-frequency ultra-sonic devices can produce actual nanoemulsions. In contrast to this concept, one research group reported for the first time the preparation of nanoemulsion by a low-energy method. Later on many authors reported about the low-energy emulsification method. More
