Recent progress in the application of plant-based colloidal drug delivery systems in the pharmaceutical sciences

Abstract

The potential for utilizing plant-derived components, such as plant proteins, polysaccharides, lipids, and phospholipids, to create targeted drug delivery systems has been demonstrated in recent years. These colloidal delivery systems can encapsulate, protect, and release pharmaceuticals, vitamins, and nutraceuticals, thereby improving their bioavailability and efficacy. Moreover, they have the potential to reduce the side effects associated with some conventional drug formulations, while still achieving controlled or targeted delivery of pharmaceutical agents by various administration routes, including oral, nasal, dermal and inhalation. The pharmacokinetic and pharmacodynamic profiles of drugs can be modulated by altering the composition, dimensions, and structure of drug formulations created using plant-based colloidal delivery systems. The utilization of plant-derived ingredients may also reduce the environmental impact and improve the sustainability of drug formulations. Initially, we provide an overview of the general characteristics and requirements of drug delivery systems. The opportunities and challenges of using plant-derived components to fabricate colloidal particles for drug delivery applications is then discussed. Finally, potential clinical applications of plant-based delivery drug systems are reviewed.
