Among many therapeutic treatments for cancer, nano-carriers are the focus of our review to illustrate the update usage of this drug delivery approach, the most likely side effects and the reality of their potential application with minimum adverse effects. Here, we demonstrate the types of these nano-carriers based on their nature with detailed recent studies about their use. The variation in the skeleton of these nanoparticles enable the selection of the suitable type with higher specifications than others.  However, the poor in vivo testing is the main stumbling block for completion of their manufacturing. This review will help the researchers to find the road map for further investigation to finally aid the pharmaceutical companies in manufacturing these nano-carriers in appropriate dosage forms to save the life of millions of people in the world.

In this study, solid dispersion using hydrophilic carriers (polyethylene glycols) and fast dissolving sugars (sorbitol and lactose) has been employed to enhance dissolution and hence the bioavailability of ibuprofen.Solid dispersions of different weight ratios (drug: carrier: fast dissolving sugars) have been prepared using fusion method.Microscopic images showed disappearance of specific features of ibuprofen, carriers and sugars in the solid dispersions.Release study of ibuprofen from prepared systems was performed in phosphate buffer pH 6.8; faster drug release was obtained from solid dispersions with high polyethylene glycol ratio and/ or from solid dispersions to which fast dissolving sugars has been added duringtheir preparations.The study also explored hydrogen bond interactions between polyethylene glycols and ibuprofen in the solid dispersions. FTIR spectroscopy confirmed intermolecular interaction at (2:1) drug to carrier mole ratio. This interaction was considered the most important factor in enhancing the dissolution of ibuprofen via solid dispersions.
