Description

The pharmaceutical formulation of the drug and the dynamic interactions between the drug, its formulation matrix, its container, and the patient's physiologic environment are dealt with by the drug delivery system. Pharmaceutics is the study of these dynamic relationships. Rheology is the study of how matter flows, typically as a liquid but also as "soft solids" or solids that flow plastically in response to an applied force rather than deforming elastically. It applies to substances with a complex microstructure, such as muds, sludges, suspensions, polymers, and other glass formers (for example, silicates), as well as to many foods and additives, bodily fluids (for example, blood), other biological materials, and other substances that fall under the category of soft materials. Adverse effects, like therapeutic effects, depend on dosage or drug levels at the target organs, therefore they can be prevented or reduced with the use of meticulous and exact pharmacokinetics, which describes how drug levels change in the body as a function of time after delivery. This book's comprehensive approach offers students, teachers, and professionals a cohesive source of information in addition to giving readers a unique viewpoint on the entire area.
