Development and physicochemical characterization of dexamethasone-loaded polymeric nanocapsule suspensions
(2008) [Artigo de periódico]The influence of drug concentration, oil phase, and surfactants on the characteristics of dexamethasone-loaded nanocapsules was investigated. The best formulations were obtained at dexamethasone concentrations of 0.25 and ... -
Development of nanocapsule suspensions and nanocapsule spray-dried powders containing melatonin
(2006) [Artigo de periódico]Suspensões de nanocápsulas contendo melatonina foram preparadas pelo método de deposição interfacial e caracterizadas (tamanho, morfologia e eficiência de encapsulação). Foram avaliadas as influências do tipo de polímero, ... -
Estabilização do ácido lipoico via encapsulação em nanocápsulas poliméricas planejadas para aplicação cutânea
(2009) [Artigo de periódico]This work reports the development of polymeric nanocapsules containing lipoic acid prepared by interfacial deposition of poli(ε-caprolactona). The suspensions showed acid pH and encapsulation efficiencies from 77 to 90%. ... -
Evaluation of lipoic acid topical application on rats skin wound healing
(2013) [Artigo de periódico]PURPOSE: To evaluate the effects of lipoic acid (thioctic acid) topical application on wound healing on rats skin, and the consequences of lipoic acid nanoencapsulation on this process. METHODS: The model used was the ... -
Hydrogels containing redispersible spray-dried melatonin-loaded nanocapsules : a formulation for transdermal-controlled delivery
(2012) [Artigo de periódico]The aim of the present study was to develop a transdermal system for controlled delivery of melatonin combining three strategies: nanoencapsulation of melatonin, drying of melatonin-loaded nanocapsules, and incorporation ... -
Micropartículas nanorrevestidas contendo um fármaco modelo hidrofóbico : preparação em etapa única e caracterização biofarmacêutica
(2008) [Artigo de periódico]The aim of this work was to prepare and characterize spray-dried nanocapsule-coated microparticles obtained in one step, using indomethacin as a hydrophobic drug model and poly(ε-caprolactone) or Eudragit® RS100, as polymers. ... -
Nanostructured systems containing an essential oil : protection against volatilization
(2011) [Artigo de periódico]The goal of this study was to evaluate the feasibility of preparing nanocapsules and nanoemulsions using tea tree oil as oily phase aiming to protect its volatilization. The nanostructures presented nanometric mean size ... -
Spray-drying technique to prepare innovative nanoparticulated formulations for drug administration: a brief overview
(2009) [Artigo de periódico]Polymeric nanoparticle systems (nanocapsules and nanospheres) present potential applications as drug delivery systems. Nevertheless, their full applications have not been exploited due to their limited shelf life when ... -
Surface morphology of spray-dried nanoparticle-coated microparticles designed as an oral drug delivery system
(2008) [Artigo de periódico]This paper was devoted to studying the influence of coating material (nanocapsules or nanospheres), drug model (diclofenac, acid or salt) and method of preparation on the morphological characteristics of nanoparticle-coated ... -
The use of nanoencapsulation to decrease human skin irritation caused by capsaicinoids
(2014) [Artigo de periódico]Capsaicin, a topical analgesic used in the treatment of chronic pain, has irritant properties that frequently interrupt its use. In this work, the effect of nanoencapsulation of the main capsaicinoids (capsaicin and ...
