Gastric cancer drugs are medications used to treat stomach cancer, either by killing cancer cells or stopping their growth. These drugs include chemotherapy agents, targeted therapies, and immunotherapies. Chemotherapy drugs like 5-fluorouracil (5-FU), capecitabine, cisplatin, and docetaxel are commonly used to shrink tumors and prevent cancer spread. Targeted therapies, such as trastuzumab and ramucirumab, focus on specific proteins in cancer cells to block their growth. Immunotherapy drugs like nivolumab and pembrolizumab help the immune system recognize and attack cancer cells. These treatments may be used before surgery (neoadjuvant), after surgery (adjuvant), or for advanced cancer to improve survival and quality of life.
