Capixet 500mg, Capecitabine Tablets

Capixet 500mg, containing the active ingredient Capecitabine, is a chemotherapy medication primarily used in the treatment of various cancers. It is an oral prodrug of 5-fluorouracil (5-FU), which means that once within the body, it transforms into its active form. Capixet is widely prescribed for cancers such as breast, colorectal, and gastric cancer. Its oral administration makes it more convenient than traditional intravenous chemotherapy, allowing for outpatient treatment and improved patient compliance.

What is Capixet 500mg?

Capixet 500mg is a tablet formulation of Capecitabine, an anticancer agent classified under antimetabolites.It is frequently used either by alone or in conjunction with further cancer treatments. Each Capixet tablet contains 500 mg of Capecitabine. This medicine is typically prescribed when cancer has spread or returned and can also be used as adjuvant therapy (treatment given after the primary treatment to lower the chance of recurrence).

How It Works / Mechanism of Action

Capecitabine is a prodrug, which means it becomes active only after being metabolized in the body. After oral administration, it undergoes a three-step enzymatic conversion to become 5-fluorouracil (5-FU) in tumor tissues.

5-FU prevents the production of DNA by inhibiting the thymidylate synthase enzyme.

By halting DNA and RNA synthesis, it prevents cancer cells from dividing and growing.

Compared to direct 5-FU administration, the selective activation of Capecitabine in tumor tissues leads to superior tumor targeting and reduced systemic toxicity.

How to Use / Indications

Capixet is indicated in the treatment of:

• Colorectal cancer: Both metastatic and adjuvant settings.
• Breast cancer: Usually in conjunction with docetaxel, especially in cases that have spread or returned.
• Gastric (stomach) cancer: Usually used in advanced or metastatic conditions.
• Other off-label uses: Pancreatic, esophageal, and biliary cancers (based on oncologist recommendation).
• Its use depends on the cancer type, stage, patient’s age, renal function, and prior chemotherapy history.

How to Take / Dosage

Body surface area (BSA) is used to determine the typical dosage. Nonetheless, a typical adult routine is:

• For 14 days, followed by a 7-day break, 1250 mg/m² twice daily (morning and evening), for a 21-day cycle.
• Example: For an average adult, this might translate to 3–4 tablets (500 mg each) taken twice a day.

Administration Instructions:

• Take tablets within 30 minutes after a meal to improve absorption and reduce side effects.
• Swallow the tablet whole with water; do not crush or chew.
• Follow your oncologist’s schedule precisely.

Other Dosage Forms / Adjustments

• Lower doses may be prescribed in elderly patients or those with liver or kidney impairment.
• Dose reduction may also be required in case of severe side effects (e.g., diarrhea, hand-foot syndrome).
• Capecitabine is available in 150 mg and 500 mg tablets, allowing flexible dose adjustment.

Capixet offers several advantages over traditional intravenous chemotherapy:

• Oral administration avoids the need for hospital visits.

Drug Interactions

Capecitabine may interact with several other medications, leading to enhanced toxicity or reduced efficacy.

Notable Drug Interactions:

• Anticoagulants (e.g., warfarin): Increased bleeding risk.
• Phenytoin: Capecitabine can increase phenytoin levels, causing toxicity.
• Leucovorin: Enhances Capecitabine’s effects and may increase toxicity.
• Allopurinol: May reduce Capecitabine’s effectiveness.
• Live vaccines: Avoid during therapy due to immune suppression.
• Always inform your doctor about all medications, supplements, or herbal products you are taking.
