Abstract: Lopinavir is the anti HIV drug which is used to treat the HIV-1 infection. In this study we used the single lopinavir drug to formulate the polymeric micelle. This study was done with the two main objectives as Objective:first to enhance the solubility and bioavailability of the BCS class IV drug and second to avoid the combination of lopinavir rand ritonavir and use single lopinavir to preparation of polymeric micelle also to avoid the disadvantages related to the oral administration. Method:The different pluronic (F188 &F127) and co-solvent (Tween80) were chosen & the micelles were prepared by using different Drug: polymer ratio with or without cosolvent and drug Lopinavir. Formulations were been characterized by critical micelle concentration(CMC) value, micellesize,DSC, XRD, loading efficiency, % drug loading and stability.Result:Mixed micelle (hydrophobic &hydrophilic) obtained from optimized batch shows the highest entrapment of 29%with the pluronic F68 with the use of co-solvent and the vesicle size of 0.156µm the DSC, FTIR, XRD study was also done for lopinavir and optimized formulation .Conclusion: The pluronic F68 with the co-solvent showed fairly high entrapment efficiency, loading capacity than the mixed Pluronic in combination.
