Preparation and Evaluation of Chitosan-Treated Alginate Microparticles for Sustained Release of All-trans Retinoic Acid
نویسندگان
چکیده
Recently, efforts have been focused on microparticles prepared with natural polymers such as alginates and chitosans. Sodium alginate in particular has been commercially applied and investigated due to its low cost and minimal processing requirements (Murata et al., 1993; Gombotz & Wee, 1998; Sezer & Akbuga, 1999a and b). The use of sodium alginate for microencapsulation has been extensively studied for a long time.

Sustained Release of Risedronate from PLGA Microparticles Embedded in Alginate Hydrogel for Treatment of Bony Lesions
Background: Inflammatory bone resorption in periodontitis can lead to tooth loss. Systemic administration of bisphosphonates such as risedronate for preventing bone resorption can cause adverse effects. Alginate hydrogel (ALG) and poly (lactic acid-co-glycolic acid) (PLGA) microparticles have been studied as drug delivery systems for sustained release of drugs. Therefore, the release pattern of...
متن کاملThe Influence of Chitosan Cross-linking on the Properties of Alginate Microparticles with Metformin Hydrochloride-In Vitro and In Vivo Evaluation.
Sodium alginate is a polymer with unique ability to gel with different cross-linking agents in result of ionic and electrostatic interactions. Chitosan cross-linked alginate provides improvement of swelling and mucoadhesive properties and might be used to design sustained release dosage forms. Therefore, the aim of this research was to develop and evaluate possibility of preparing chitosan cros...
