Use of Natural Gum in Poorly Water - Soluble Drug Solid Dispersion and Solubility Enhancement

Improving the solubility of drugs that are poorly soluble in water is a significant difficulty in pharmaceutical formulation development. To improve the solubility and rate of dissolution of pharmaceuticals, a commonly used technique called solid dispersion involves dispersing the drugs inside a hydrophilic carrier matrix. Because of their excellent environmental properties, affordability, and biocompatibility, natural gums derived from plants have garnered a lot of attention as flexible carriers in solid dispersion formulations. Natural gums that are hydrophilic and able to create films include guar gum, xanthan gum, and gum Arabic. These properties increase the surface area and improve the dissolution kinetics of the polymeric matrix by aiding in the dispersion of drug molecules throughout it. Recent advancements in the subject are also covered in the abstract, such as the use of natural gums in conjunction with specific other materials to increase the solubility and bioavailability of pharmaceuticals. Two cooperative processing methods that have showed promise in enhancing formulation stability and obtaining superior drug solubility characteristics are co-precipitation and hot melt extrusion. In order to increase the solubility of medications with limited water solubility, the current study explores the possible use of natural gums in solid dispersion systems. The paper’s first part looks into solid dispersion and discusses the role that natural gums play in making medications more soluble. Moreover, improved treatment outcomes and higher patient adherence may result from the application of cutting-edge technologies and techniques meant to boost pharmaceutical solubility.
