Mapstabine 500mg Tablet

About

Mapstabine, commonly known as Capecitabine, is an oral fluoropyrimidine carbamate, functioning as a prodrug that is selectively converted into its active cytotoxic metabolite, 5-fluorouracil (5-FU), primarily within tumor cells. This targeted activation is mediated by specific enzymes, including thymidine phosphorylase, which are often found in higher concentrations within cancerous tissues. Once converted, 5-FU interferes with DNA and RNA synthesis, leading to cell cycle arrest and programmed cell death (apoptosis) in rapidly dividing cancer cells. This mechanism makes it an effective chemotherapy agent for various solid tumors, including metastatic colorectal cancer, adjuvant treatment of colon cancer, metastatic breast cancer, and advanced gastric cancer, while aiming to minimize systemic toxicity compared to intravenous 5-FU.
