Carbon nanotubes: An alternative for platinum-based drugs delivery systems

Currently, nanomedicine is approaching the research of nanomaterials that could work as drug delivery systems, to increase the efficiency, specificity and safety of drugs reducing toxicity and side effects. In this regard, carbon nanotubes have acquired great interest due to their physicochemical properties. The use of platinum-based drugs is facing some troubles in the clinic due to their side effects such as nephrotoxicity, neutropenia, neurotoxicity, among others. In addition, cases of tumors resistant to these drugs have been recently observed. The goal of this review was to analyze the reports about the use of formulations of platinum-based drugs in carbon nanotubes, to know and establish the most functional and potential conditions for its use in cancer treatment, identifying perspectives and develop areas for the improvement of these nanomaterials in the application of cancer therapy.
