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 ...
Polysaccharides as safer release systems for agrochemicals
(Springer, 2015-01-01)
Agrochemicals are used to improve the production of crops. Conventional formulations of agrochemicals can contaminate the environment, in particular in the case of intensive cropping. Hence, there is a need for controlled-release ...
Oil-in-water emulsion development for the encapsulation and sustained release of xanthone
(Taylor & Francis, 2020-02)
In the present work, an oil-in-water emulsion was developed for the encapsulation of xanthone, a potent anti-inflammatory and antitumor molecule of natural source. The xanthone is insoluble in water so it was encapsulated ...

Natural latex films as carrier for casearia sylvestris swartz extract associated with ciprofloxacin
(2015)
In order to create a new sustained drug delivery system applied for tissue regeneration, this study beget a natural rubber latex (NRL) film with Casearia sylvestris extract and ciprofloxacin. Manipulated from the biomaterial ...
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 ...
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 ...
Controlled release system for ametryn using polymer microspheres: Preparation, characterization and release kinetics in water
(Elsevier B.V., 2011-02-28)
The purpose of this work was to develop a modified release system for the herbicide ametryn by encapsulating the active substance in biodegradable polymer microparticles produced using the polymers poly(hydroxybutyrate) ...
