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 ...
Preparation and physicochemical characterization of drug loaded in castor oil-based polyurethane
(Springer, 2020-02-01)
Castor oil is an environmentally friendly alternative to hydrocarbon-based feedstocks for the synthesis of polyurethanes due to its major constituent, ricinoleic acid. This work aimed to obtain and characterize castor ...

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 ...

Modeling a system of phosphated cross-linked high amylose for controlled drug release. Part 2: Physical parameters, cross-linking degrees and drug delivery relationships
(Elsevier B.V., 2009-04-17)
High amylose cross-linked to different degrees with sodium trimetaphosphate by varying base strength (2% or 4%) and contact time (0.5-4 h) was evaluated as non-compacted systems for sodium diclophenac controlled release. ...

Novel sustained-release of stryphnodendron obovatum leaves extract using natural rubber latex as carrier
(2015-01-01)
Natural rubber latex biomembranes (NRL), obtained from rubber tree Hevea brasiliensis (Willd. ex A. Juss.) Mull. Arg., have been used as sustained drug release of drugs and plant extracts with medicinal properties. The ...
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 ...
