  • Title: Prospective of guar gum and its derivatives as controlled drug delivery systems.
    Author: Prabaharan M.
    Journal: Int J Biol Macromol; 2011 Aug 01; 49(2):117-24. PubMed ID: 21596058.
    Abstract:
    Guar gum is a non-ionic polysaccharide that is found abundantly in nature and has many properties desirable for drug delivery applications. However, due to its high swelling characteristics in aqueous solution, the use of guar gum as delivery carriers is limited. Guar gum can be modified by derivatization, grafting and network formation to improve its property profile for a wide spectrum of biomedical applications. This review article is aimed at focusing the recent efforts and developments on guar gum and its derivatives as colon-specific, antihypertensive, protein and transdermal drug delivery systems. Based on the literatures reviewed, it is concluded that guar gum and its derivatives in the various forms such as coatings, matrix tablets, hydrogels and nano/microparticles can be exploited as potential carriers for targeted drug delivery.
