"In this work, the peel of Arapey Sweet Potato (Ipomoea batatas), a vegetable waste, was used as a source of phenolic compounds which are widely recognized as beneficial antioxidants for human health. The extract obtaine...

Cymbopogon citratus essential oil (CCEO) is widely used in food, cosmetics and pharmaceutical fields. The aim of this study was to compare two different methods of encapsulating CCEO. The o/w emulsion method was employed...

The purpose of the present investigation is to study the effect of incorporation of gelucire 39/01 and 50/13 on encapsulation efficiency and release of water soluble drug (metronidazole, log P = 0.0) from floating gellan...

Nanoparticles are widely utilized to overcome drugs insolubility problems and sustain release improving the bioavailability. Zinc phthalocyanine, a hydrophobic photosensitizer with solubility problems, was loaded in PLA ...

Bilayer vesicles, such as liposomes and niosomes, are widely known as efficient delivery systems for drugs. Spherical vesicles consisting of amphipatic non-ionic surfactants named niosomes are arranged in one or more con...

"Poly(amide-triazole) and poly(ester-triazole) synthesized from d-galactose as a renewable resource were applied for the synthesis of nanoparticles (NPs) by the emulsification/solvent evaporation method. The NPs were cha...

Nimesulide was formulated as sustained release microcapsules using biodegradable polymer Poly(D,L-lactide-co-glycolide) (PLGA) as the release material by non-solvent addition coacervation method. The prepared microcaps...

El objetivo del este estudio fue el desarrollo y la caracterización del microesferas de etilcelulosa contiendo diclofenaco y la determinación del perfil de la liberación del fármaco in vitro. Las microesferas fueron ...

The objective of the present investigation was to evaluate the potential of gellan gum- low molecular weight chitosan (GG-LMCH) polyelectrolyte complex (PEC) in the form of beads as prolonged release stomach specific flo...

Hydroquinone (HQ) is a drug reported to possess manifold biological activities. HQ is highly unstable into various topical vehicles, presenting low topical bioavailability and a relevant level of toxicity. The Pluronic®...

This work is focused on the development of a new particulate drug delivery system using sodium alginate (SA) and modified hydrophobic hydroxyl propyl methyl cellulose (HPMC, 60L grade) containing diclofenac as a model dr...

The present study involves the preparation of nimesulide-chitosan microparticles (NCM) as sustained delivery carriers with different polymer concentrations by pH change coacervation method using glutaraldehyde as cross-l...
