Abstract

In this fast-growing nanotechnological drug delivery era the focus is narrowing to real nanocarriers that can be commercialized to improve human healthcare. Many nanocarriers have shown drug delivery potential; however, only a few have shown the real potential to wind up in the hands of customers (the patients). In drug delivery, colloidal system and polymeric micelles have attracted great attention in the recent three decades. Generally, polymeric micelles have high stability than surfactant-based micelles. These carriers have recently been advanced as newer and effective drug delivery system for targeting of amphiphilic and poorly water-soluble drug(s). The application of polymeric micelles to assist drug delivery has already been established. These are shown to be beneficial for the stabilization and distribution of compound to target the site. Recently, to enhance the accumulation and to reduce toxicity, the micellar formulation is targeted to a particular site. They have been extensively employed to improve the delivery characteristics of poorly water-soluble bioactive. Numerous polymeric micellar architects have been developed and studied over the past few decades. Many of them have gradually progressed through clinical trials. This review summarizes the relevant properties of polymeric micelles including the types of micelles, their formation, critical micelle concentration, size of polymeric micelles, and shape of molecules and other attributes.

    A similar trend was observed for EE, except when the micelles were loaded with PTX. In this case, the percentage of EE decreased by 11.7% (from 88.9% to 77.2%) when the D/C ratio increased from 0.2 to 0.3, which can be explained by the limited solubilization capacity of the micelles [36,37]. These results suggested that CouPEG was an excellent carrier for PTX and CUR.

    For the transport of poorly water-soluble active drugs, polymeric micelles have been substantially investigated as a vehicle [60]. The Interior and exterior composition of polymeric micelles are made up of amphiphilic block copolymers [61], which in an aqueous solvent at a concentration above the critical micellar concentration (CMC) undergoes self-assembly into a micellar system [62]. The interior core of the micelles is made up of a hydrophobic block copolymer, which contains the hydrophobic drugs.
