Encapsulação da rifampicina em matrizes poliméricas flutuantes obtidas por liofilização a partir de metilcelulose e ftalato de hidroxipropilmetilcelulose. Avaliação da liberação in vitro
(2001-12-01)
Floating multiparticles for oral administration with different compositions were studied from a matricial polymeric system to obtain sustained release. The polymers used in the multiparticles constitution were methylceullose ...
LC Evaluation of In Vitro Release of AZT from Microemulsions
(Vieweg, 2009-06-01)
A reversed phase LC method was developed and validated to analyze the in vitro release of AZT from microemulsions. A mobile phase of acetonitrile:water (15:85) was used. The method validation showed good selectivity and ...
In vitro release of propolis from gelatin microparticles prepared by spray-drying technique
(2004-12-01)
The purpose of this study was to investigate the in vitro release of propolis from gelatin microparticles. Gelatin microparticles containing propolis extractive solution (PES) were prepared by spray-drying technique. ...
Ethylcelullose microspheres containing sodium diclofenac: Development and characterization
(2006-07-01)
The objective of the present study was the development and characterization of ethylcellulose microspheres containing diclofenac and the determination of the in vitro drug release profile. Microspheres were prepared by ...
Caffeine Encapsulated in Small Unilamellar Liposomes: Characerization and In Vitro Release Profile
(Taylor & Francis Inc, 2013-10-03)
Liposomes containing hydrogenated soy phosphatidylcholine (PCH), with or without cholesterol (CHOL) and caffeine (CAF), were prepared by sonication and characterized for encapsulation efficiency and mean diameter. Dynamic ...
Inclusion complex of piroxicam with beta-cyclodextrin and incorporation in cationic microemulsion. In vitro drug release and in vivo topical anti-inflammatory effect
(Elsevier B.V., 2001-07-03)
Topical formulations of piroxicam were evaluated by determination of their in vitro release and in vivo anti-inflammatory effect. The in vitro release assay demonstrated that the microemulsion (ME) systems provided a ...
Preparation and characterization of poly(ε-caprolactone) nanospheres containing the local anesthetic lidocaine
(2013-01-01)
The objective of this work was to develop a modified release system for the local anesthetic lidocaine (LDC), using poly(ε-caprolactone) (PCL) nanospheres (NSs), to improve the pharmacological properties of the drug when ...
Development and in vitro evaluation of lyotropic liquid crystals for the controlled release of dexamethasone
(2017-08-02)
In this study, amphiphilic polymers were investigated as biomaterials that can control dexamethasone (DXM) release. Such materials present interfacial properties in the presence of water and an oily phase that can result ...
An analytical GC-MS method to quantify methyl dihydrojasmonate in biocompatible oil-in-water microemulsions: physicochemical characterization and in vitro release studies
(2018-02-07)
Microemulsions (MEs) loaded with methyl dihydrojasmonate (MJ) were developed to improve the aqueous solubility of this drug. The composition of the formulations ranged according to the oil/surfactant ratio (O/S). The MEs ...
