Cancer chemotherapeutic administration by oral route has the potential to create “hospitalization free chemotherapy”. Such a therapeutic approach will improve patient compliance and significantly reduces the cost of treatment. In current clinical practice, chemotherapy is primarily carried out by intravenous injection or infusion and leads to various unwanted effects. Despite the presence of oral delivery challenges like poor aqueous solubility, low permeability, drug stability and substrate for multidrug efflux transporter, cancer chemotherapy delivery through oral administration has gain much attention recently due to having more patient compliance compared to intravenous mode of administration. In order to address the multifaceted oral drug delivery challenges, a hybrid delivery system being conceptualized to merge the benefits of both polymeric and lipid-based drug carriers. Polymer-lipid hybrid systems have presented various significant benefits as an efficient carrier to facilitate oral drug delivery by surmounts the different associated obstacles. This carrier system found suitable to overcome the numerous oral absorption hindrances and facilitating the intravenous-to-oral switch in cancer chemotherapy. In this review, we aimed to discuss the different biopharmaceutic challenges in oral delivery of cancer chemotherapy and how this hybrid system may provide solutions to such challenges.
