Abstract

Administering therapeutics through the oral route is a pervasive and widely approved medication administration approach. However, it has been found that many drugs show low systemic absorption when delivered through this route. Such limitations of oral drug delivery can be overcome by polymeric micelles acting as vehicles. As a result, they improve drug absorption by protecting loaded drug substances from the gastrointestinal system's hostile conditions, allowing controlled drug release at a specific site, extending the time spent in the gut through mucoadhesion, and inhibiting the efflux pump from reducing therapeutic agent accumulation. To promote good oral absorption of a weakly water-soluble medicinal drug, the loaded medicine should be protected from the hostile atmosphere of the GI tract. Polymeric micelles can be stacked with a broad assortment of ineffectively dissolvable medications, improving bioavailability. This review discusses the major mechanism, various types, advantages, and limitations for developing the polymeric micelle system and certain micellar drug delivery system applications. The primary goal of this review is to illustrate how polymeric micelles can be used to deliver poorly water-soluble medications.
