Plantago Ovata and Locust Bean Gum as a Natural Polymer in Hydrodynamically Balanced Systems: A Review

Hydrodynamically Balanced systems have wide development as they have achieved the parameters of modern drug delivery system, it is a type of system which owes very tremendous and curative benefits for the delivery of oral controlled release dosage forms and have wide properties in many aspects such as its main role is to maintain the effective concentration in the system for longer period of time. To reduce the gastric mucosal irritation due to the presence of synthetic polymers, being a natural polymer incorporation of Plantago ovate (Psyllium Husk) could ease out the mucosal irritation in the gastric region. Due to its properties such as a rate-controlling polymer possessing a very good quality of swelling and good gelling nature, and also incorporated as a matrix-forming agent basically in the modified release formulation. Locust bean gum can be used as sustained-release carriers and release modifiers for the delivery of drugs. It is a neutral plant galactomannan extracted from the seeds (kernels) of the carob tree Ceratonia siliqua L fabaceae. Nowadays it is focussing polymer and a lot of researchers are focussing on exploring the potential in topical drug delivery, colonic drug delivery, oral sustained drug delivery, ocular drug delivery, buccal drug delivery.
