| Popis: | In this study, we designed a fixed-dose combination (FDC) for Darunavir (DRV) and Ritonavir (RTV) using molecular simulations as a tool. Molecular modeling allowed us to choose the solvent and antisolvent required for the formation of nanosuspension by estimating the solubility parameter. Molecular dynamics simulations and the analysis of the same provided useful information at the molecular level. Hydrogen bonding interactions, radial distribution functions, the radius of gyration, diffusion coefficient, and density profile analysis allowed us to see the formation of particles virtually. With the information obtained from the simulations, we were able to design our experiments and found that the results from experiments complemented the findings from the simulations. Nanosuspension was prepared by using high-speed homogenization (HSH) followed by probe sonication. The solid-state characterization studies demonstrated that both the drugs remain in the amorphous form with absence of any intermolecular interactions. The pharmacokinetic study indicated a significant improvement in the oral bioavailability of DRV/RTV nanosuspension compared to the pure drug combination. Thus, the studies demonstrated that the developed FDC nanosuspension could be a useful alternative dosage form for treating human immunodeficiency virus (HIV) infected patients Refereed/Peer-reviewed |
