Abstract
Tyrosine kinase inhibitors (TKIs) are used as targeted therapy for cancer by inhibiting the signaling pathway and tumor growth. Many TKIs got approved by FDA in recent times for the treatment of cancer by oral route. However, the TKIs have formulation challenges leading to compromised bioavailability which can cause a weak therapeutic response. The cancer nanotherapeutics using nanocarriers based drug delivery has emerged as an advanced tool to provide a solution to formulation challenges and a better cancer therapy by overcoming the limitations in conventional cancer therapy. This review describes the various formulation issues of anticancer drugs with a special reference to TKIs, as well as the capability of solid lipid nanoparticles (SLNs) for an efficient nano targeted cancer drug delivery.
