Journal ArticleDOI
Characterization of chitosan acetate as a binder for sustained release tablets.
Jurairat Nunthanid,M. Laungtana-Anan,Pornsak Sriamornsak,Sontaya Limmatvapirat,Satit Puttipipatkhachorn,Lee Yong Lim,Eugene Khor +6 more
TL;DR: It was suggested that the simple incorporation of spray-dried chitosan acetate as a tablet binder could give rise to controlled drug delivery systems exhibiting sustained drug release.
Journal ArticleDOI
Enhanced enteric properties and stability of shellac films through composite salts formation.
Sontaya Limmatvapirat,Chutima Limmatvapirat,Satit Puttipipatkhachorn,Jurairat Nuntanid,Manee Luangtana-anan +4 more
TL;DR: Optimized shellac properties could be easily accomplished by composite salts formation, resulting in more solubility and stability.
Journal ArticleDOI
Modification of physicochemical and mechanical properties of shellac by partial hydrolysis
Sontaya Limmatvapirat,Chutima Limmatvapirat,Manee Luangtana-anan,Jurairat Nunthanid,Toshio Oguchi,Yuichi Tozuka,Keiji Yamamoto,Satit Puttipipatkhachorn +7 more
TL;DR: The results demonstrated that acid value (AV) of shellac increased with prolongation of hydrolysis time, and the films prepared from hydrolysed shellac were more flexible and soft than those prepared from native shellac.
Journal ArticleDOI
Preparation and in vitro evaluation of a multiple-unit floating drug delivery system based on gas formation technique
TL;DR: Both the rapid floating and the sustained release properties were achieved in the multiple-unit floating drug delivery system developed in this present study.
Journal ArticleDOI
Utilization of shellac and gelatin composite film for coating to extend the shelf life of banana
Sitthiphong Soradech,Sitthiphong Soradech,Jurairat Nunthanid,Sontaya Limmatvapirat,Manee Luangtana-anan +4 more
TL;DR: In this article, a composite film based on 60% shellac and 40% gelatin with and without PEG 400 at 5% was used to extend the shelf life of post-harvest bananas.
