Aims: This review provides a landscape of US FDA-approved drugs for liver cancer. The study evaluates these FDA-approved agents’ chemical constituents and pharmacology, as well as the mechanism of action and adverse response profiles, to enhance understanding of their therapeutic efficacy and safety and to draw the need for further analysis to build combination therapy with these drugs. Methodology: A thorough assessment of US FDA-approved drugs for liver cancer required examining the regulatory documents from the FDA and peer-reviewed literature. It examines US FDA-approved drugs for advanced or unresectable liver cancer, including Sorafenib tosylate, Regorafenib, Lenvatinib, Nivolumab, Atezolizumab, Bevacizumab, Cabozantinib-S-Malate, Pembrolizumab, Ipilimumab, Tremelimumab-actl and Ramucirumab. This review covers the analysis of the pharmacological properties of these drugs, focusing on chemical structure, mechanisms of action, clinical efficacy, and corresponding toxicity, to provide a detailed understanding of their function in the treatment of liver cancer. Conclusion: Drugs that are approved by the US FDA for liver cancer have transformed the management of liver cancer, especially in advanced stages while surgery is not feasible. These substances function via a variety of methods, such as immune evasion, angiogenesis, and tumor growth inhibition. However, they are associated with several adverse effects, including hepatotoxicity, tiredness, diarrhea, hypertension, and immune-related consequences. Ongoing discoveries in targeted therapies and immunotherapies provide promise for the enhancement of liver cancer surgery outcomes, with ongoing research into combination therapies and novel therapeutic strategies.
