Brief Overview of Xeloda (generic name: capecitabine)
Xeloda, also known by its generic name capecitabine, is a medication used in cancer treatment. It belongs to a class of drugs called antimetabolites and is specifically classified as a nucleoside metabolic inhibitor.
Capecitabine is an oral chemotherapy drug that is designed to target and destroy cancer cells in the body. It is often used in the treatment of breast cancer, colorectal cancer, and gastrointestinal tumors.
How Does Xeloda Work?
Xeloda works by entering the body and being converted into 5-fluorouracil (5-FU), an active anti-cancer drug. Once converted, 5-FU interferes with the growth of cancer cells, causing them to eventually die off. This process, known as cytotoxicity, helps to slow down the progression of cancer and may even lead to tumor shrinkage.
Usage and Dosage
Capecitabine is typically taken orally, usually in the form of tablets. The dosage and frequency may vary depending on the specific type of cancer being treated, as well as the individual patient’s condition and overall health.
It is important to follow the prescribed dosage instructions given by the healthcare provider. Taking more or less than the recommended dose can affect the effectiveness of the treatment and may lead to unwanted side effects.
Possible Side Effects
Like any medication, Xeloda may cause side effects in some patients. It is important to be aware of these potential side effects and report them to a healthcare provider if they occur. Common side effects may include:
- Diarrhea
- Nausea or vomiting
- Fatigue or weakness
- Hand-foot syndrome (palmar-plantar erythrodysesthesia)
- Loss of appetite
- Abdominal pain
It is essential to seek medical attention if any severe or persistent side effects are experienced.
Before Taking Xeloda
Before starting treatment with Xeloda, it is crucial to inform the healthcare provider about any pre-existing medical conditions, including allergies, liver or kidney problems, and any ongoing medications or supplements being taken.
Pregnant women, women who are breastfeeding, and individuals with a known dihydropyrimidine dehydrogenase (DPD) enzyme deficiency should avoid using Xeloda, as it may pose potential risks.

It is important to always consult a healthcare professional regarding specific questions or concerns related to Xeloda or any other medication.
Point 2: How Xeloda Works
Xeloda, also known by its generic name capecitabine, is an oral chemotherapy medication that is commonly used in the treatment of various types of cancer, including breast cancer, colorectal cancer, and gastric cancer. It belongs to a class of drugs called antimetabolites, which work by interfering with the growth and spread of cancer cells.
Capecitabine as a Prodrug:
Xeloda is what is known as a prodrug, which means that it is inactive until it is metabolized in the body. Once taken orally, it is subsequently converted to its active form through a series of enzymatic reactions in the liver and tumor tissues. This conversion process is necessary for capecitabine to exert its therapeutic effects.
| Step | Enzyme | Final Product |
|---|---|---|
| 1 | Carboxylesterase | 5′-Deoxy-5-fluorocytidine (5′-DFCR) |
| 2 | Cytidine deaminase | 5′-Deoxy-5-fluorouridine (5′-DFUR) |
| 3 | Thymidine phosphorylase | 5-Fluorouracil (5-FU) |
“The metabolic conversion of Xeloda is a multi-step process involving several enzymes. Carboxylesterase converts Xeloda to 5′-deoxy-5-fluorocytidine (5′-DFCR), which is then converted to 5′-deoxy-5-fluorouridine (5′-DFUR) by cytidine deaminase. Finally, thymidine phosphorylase converts 5′-DFUR to its active form, 5-fluorouracil (5-FU).”
Mechanism of Action:
Once converted to 5-fluorouracil (5-FU), Xeloda exerts its therapeutic effects through several mechanisms:
- Direct Cytotoxicity: 5-FU incorporates into the DNA and RNA of cancer cells, leading to the disruption of their normal functions and ultimately causing cell death.
- Thymidylate Synthase Inhibition: 5-FU inhibits thymidylate synthase, an enzyme required for the synthesis of DNA. As a result, cancer cells are unable to produce new DNA strands and are unable to divide and grow.
- Angiogenesis Inhibition: 5-FU interferes with the formation of new blood vessels that supply nutrients to cancer cells. This hinders the tumor’s ability to grow and spread.
“By incorporating into the DNA and RNA of cancer cells, 5-fluorouracil disrupts their normal functions and ultimately leads to cell death. Additionally, it inhibits thymidylate synthase, an enzyme required for DNA synthesis, and interferes with angiogenesis, the process by which new blood vessels are formed to support tumor growth.”
It is important to note that Xeloda is typically prescribed in combination with other chemotherapy drugs or targeted therapies, depending on the specific type and stage of cancer being treated. This combined approach helps to maximize treatment efficacy and improve patient outcomes.
Using Xeloda (Generic Name: Capecitabine) in Cancer Treatment
Capecitabine, commercially known as Xeloda, is a medication mainly used in the treatment of cancer. It belongs to a class of chemotherapy drugs called antimetabolites, which work by interfering with the growth and spread of cancer cells in the body.
How Does Xeloda Work?
Xeloda is an orally administered chemotherapy drug. Once ingested, it is enzymatically converted into a substance called fluorouracil (5-FU) in the body. Fluorouracil is referred to as a prodrug because it requires activation to become an active anticancer agent.
Fluorouracil (5-FU) interferes with the DNA and RNA synthesis processes within cancer cells. It inhibits the activity of an enzyme called thymidylate synthase, which is responsible for producing the building blocks necessary for DNA synthesis. By inhibiting this enzyme, Xeloda disrupts the cancer cells’ ability to replicate and grow, leading to their eventual death.
Conditions Treated with Xeloda
Xeloda is commonly prescribed for the treatment of various types of cancer, either as a single agent or in combination with other chemotherapy drugs. It is indicated for the following conditions:
- Metastatic colorectal cancer: Xeloda is typically used as a first-line treatment for metastatic colorectal cancer. It can be administered alone or in combination with other medications.
- Metastatic breast cancer: In cases of advanced or recurrent breast cancer, Xeloda is used as a chemotherapy option either alone or in combination with other drugs.
- Gastric (stomach) cancer: Xeloda is considered an effective treatment option for gastric cancer that has spread or cannot be removed through surgery.
- Adjuvant colon cancer treatment: After surgical removal of the primary colon tumor, Xeloda may be prescribed as an adjuvant treatment to reduce the risk of cancer recurrence.
Important Points to Consider
Before starting the treatment with Xeloda, it is essential to take note of the following considerations:
- Xeloda should only be used under the supervision and prescription of a qualified healthcare professional.
- Patients should inform their healthcare provider about any liver, kidney, or heart conditions, as Xeloda may require dose adjustments or extra monitoring in such cases.
