Capecitabine NEW

Description:

Capecitabine is an oral chemotherapy medication that is primarily used in the treatment of various types of cancer, particularly breast cancer and colorectal cancer. It is a prodrug that is converted into its active form, 5-fluorouracil (5-FU), in the body.

Key Information and Uses:

Mechanism of Action:

Capecitabine is converted to 5-fluorouracil (5-FU) in the liver and tumor tissues. 5-FU interferes with the synthesis of DNA and RNA by inhibiting thymidylate synthase, which is crucial for DNA replication. This action leads to the inhibition of cancer cell growth and proliferation.
