Capebest 500 Tablet is a widely prescribed medication used for the treatment of certain types of cancer. Its active ingredient, capecitabine, belongs to the class of drugs known as antimetabolites, which work by interfering with the growth and spread of cancer cells in the body. This article offers a deep dive into the uses, side effects, precautions, dosage guidelines, and benefits of Capebest 500 Tablet.
What is Capebest 500 Tablet?
Capebest 500 Tablet is a chemotherapy drug that contains capecitabine, a prodrug that is converted into 5-fluorouracil (5-FU) in the body. 5-FU is an antineoplastic agent that helps prevent cancer cell replication. This drug is primarily used for treating:
- Colorectal cancer
- Breast cancer
- Gastric cancer
The tablet is often used in combination with other chemotherapy agents or as a standalone therapy, depending on the type and stage of cancer being treated.
How Does Capebest 500 Tablet Work?
Capecitabine, the active ingredient in Capebest 500 Tablet, is absorbed through the gastrointestinal tract and then converted into its active form (5-FU) by enzymes located in cancer cells. The 5-FU works by interfering with the DNA synthesis of cancer cells, inhibiting their ability to divide and grow.
Mechanism of action:
- Inhibition of thymidylate synthase, which is essential for DNA replication.
- Disruption of RNA and protein synthesis within the cancer cells.
- Apoptosis, or programmed cell death, is initiated as a result of these disruptions.
Uses of Capebest 500 Tablet
