As one of the biggest causes of death globally, cancer requires ongoing breakthroughs in treatment methods. This review delves into the critical role that pharmaceutics play in cancer treatment, showcasing cutting-edge approaches like immunotherapy, hormone therapy, targeted therapy, and chemotherapy. The potential of novel drug delivery technologies, such as liposomes, dendrimers, and nanoparticles, to improve therapeutic efficacy and lessen side effects is investigated. The notion of customised medicine, propelled by pharmacogenomics and biomarkers, is examined, underscoring its function in customising therapies to distinct patient profiles. Emerging treatments like CRISPR and gene therapy are discussed, as well as problems like medication resistance and toxicity control. In order to give a thorough picture of the current situation and potential future developments in cancer pharmaceutics, the analysis finishes with future directions in pharmaceutics, such as predictive modelling and AI in medication development.
