Description

Liquid suspensions, liquid emulsions, semisolid liquid-filled systems, foams, and powder-filled solid polymeric systems are only a few examples of dispersed systems. Pharmaceutical film coatings are an example of powder-filled solid polymeric systems. Particularly when the droplets or solid particles of the scattered phase interact with one another or with the surrounding bulk phase, the rheological and mechanical properties of dispersed systems are poorly understood. It focuses on certain disperse system dosage form types, including formulation techniques and stability test methodologies. One of the key factors in achieving the optimum drug concentration in the systemic circulation for the desired (expected) pharmacological response is solubility, the phenomenon of solute dissolving in solvent to produce a homogeneous system. One of the main issues with different types of medications is their poor water solubility, and numerous strategies have been developed to improve their solubility. The behaviour of a drug's solubility in water continues to be one of the most difficult areas of formulation development. The science and technology involved in creating disperse systems like emulsions, suspensions, foams, and others are presented in detail in this book.
