Absolute bioavailability determination of a sustained release theophylline DETERMINACION DE LA BIODISPONIBILIDAD ABSOLUTA DE UN COMPRIMIDO DE LIBERACION CONTROLADA DE TEOFILINA
(1993)
The absolute biovailability of a sustained release tablet developed in our laboratory was evaluated. The formulation employs acrylic resins Eudragit as the sustaining release system and tablets were obtained using conventional ...
Experimental problems in the application of UV/visible based methods as the quantification tool for the entrapped/released insulin from PLGA carriers
(John Wiley & Sons Ltd, 2009-12)
Background: Controlled release of medicaments from biodegradable polymers remains the most convenient way for their sustained release. Although a number of articles have been published, experimental work involving the ...

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 ...
Alginate-Based Delivery Systems for Bevacizumab Local Therapy: In Vitro Structural Features and Release Properties
(2019-04-01)
Alginate-based polyelectrolyte complexes (PECs) and hydrogel were engineered as platforms for local bevacizumab (BVZ) therapy. This study provides deep comprehension on the microstructures of such systems, and their ...
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 ...
