"This new volume, Natural Polymers for Pharmaceutical Applications, Volume 1: Plant-Derived Polymers, presents some of the latest research on the applications of natural polymers in drug delivery and therapeutics for healthcare benefits. Polymers and their applications from several plants are discussed in depth, including tamarind gum, gum Arabic, natural carbohydrate polymer gum tragacanth, pectin, guar gum and its derivatives, locust bean gum, sterculia gum, okra gum, and others. The use of the polymers derived from plants as potential pharmaceutical excipients is expanding day by day because of their stability in the biological system, drug-releasing capability, drug-targeting abilities, as well as their bioavailability. During past few decades, many plant-derived polymers have been studied for use as pharmaceutical excipients, such as suspending agents, emulsifiers, binders, disintegrants, gelling agents, biomucoadhesive agents, matrix formers, release retardants, enteric resistants, etc., in various pharmaceutical dosage forms like tablets, microparticles, nanoparticles, ophthalmic preparations, gels, emulsions, suspensions, etc. In addition, their applicability has been established for further industrial uses as well. Volume 2: Marine- and Microbiologically Derived Polymers, looks at how these polymers have been explored and exploited for pharmaceutical uses, such as in tablets, microparticles, nanoparticles, ophthalmic preparations, gels, emulsions, suspensions, etc. Some commonly used marine- and microbiologically derived polymers used as pharmaceutical excipients include alginates, agar-agar, gellan gum, carrageenan; chitosan, xanthan gum, and others.

The book focuses on important recent advances from experts around the world on marine-derived polysaccharides and pharmaceutical applications of alginates, agar-agar, gellan gum, carrageenan, chitosan derivatives, xanthan gum. Volume 3: Animal-Derived Polymers looks at how these polymers can be exploited as pharmaceutical excipients in various pharmaceutical dosage forms, like microparticles, nanoparticles, ophthalmic preparations, gels, implants, etc. The commonly used animal-derived polymers used as pharmaceutical excipients are hyaluronic acid (hyaluronan), albumin, collagen, gelatin, chondroitin, etc.".
