- 500mg
Colorectal Cancer
Adjuvant treatment for colon cancer
- Indicated as a single agent for adjuvant treatment in patients with Dukes’ C colon cancer who have undergone complete resection of the primary tumor when treatment with fluoropyrimidine therapy alone is preferred
- Capecitabine was noninferior to 5fluorouracil and leucovorin (5-FU/LV) for disease-free survival; consider results of combination chemotherapy trials, which have shown improvement in disease-free and overall survival, when prescribing single-agent capecitabine in the adjuvant setting

- Deaths from severe enterocolitis, diarrhea, and dehydration reported in older patients receiving weekly leucovorin and 5-FU
-
CYP2C9 substrates
- Caution if coadministered with CYP2C9 substrates
- Other than warfarin, formal drug-drug interaction studies have not been conducted with other CYP2C9 substrates
-
Allopurinol
- Avoid coadministration
- Coadministration may decrease concentration of capecitabine’s active metabolites
Pregnancy & Lactation
Pregnancy
Based on findings in animal reproduction studies and its mechanism of action, fetal harm may occur when administered to pregnant females; limited available human data are not sufficient to inform drug-associated risk during pregnancy
Pregnancy testing recommended for females of reproductive potential before initiating therapy
Animal studies
- Therapy in pregnant animals during organogenesis caused embryo lethality and teratogenicity in mice and embryo lethality in monkeys at 0.2 and 0.6 times, respectively, the exposure (AUC) in patients
Contraception
- Females of reproductive potential: Use effective contraception during treatment and for 6 months after last dose
- Males with female partners of reproductive potential: Use effective contraception during treatment and for 3 months after last dose
Infertility
- Based on animal studies, may impair fertility in females and males
Lactation
Data are unavailable regarding presence in human milk, effects on milk production, or effects on breastfed infants; drug metabolites were present in milk of lactating mice
Owing to potential for serious adverse reactions from exposure in breastfed infants, advise females not to breastfeed during therapy and for 2 weeks after final dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Fluoropyrimidine carbamate with antineoplastic activity; it is a prodrug of 5’-deoxy-5-fluorouridine (F'-DFCR), which is then converted to 5-fluorouracil (5-FU)
Both normal and tumor cells metabolize 5-FU to 5-fluoro-2’-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP)
FdUMP and FUTP
- These metabolites cause cell injury by 2 different mechanisms
- First, FdUMP and the folate cofactor, N5-10-methylenetetrahydrofolate, bind to thymidylate synthase to form a covalently bound ternary complex; this binding inhibits thymidylate formation from 2’-deoxyuridylate; thymidylate is the necessary precursor of thymidine triphosphate, which is essential for DNA synthesis, so that a deficiency of this compound can inhibit cell division
- Second, nuclear transcriptional enzymes can mistakenly incorporate FUTP in place of uridine triphosphate (UTP) during RNA synthesis; this metabolic error can interfere with RNA processing and protein synthesis
Absorption
Peak Plasma Time: 1.5 hr (capecitabine); 2 hr (5-FU)
Food
- Food reduces both rate and extent of capecitabine absorption of capecitabine
- In all clinical trials, patients were instructed to administer capecitabine within 30 minutes after a meal
- Recommended to administer with food
Distribution
Protein bound: <60% (primary to albumin ~35%)
Metabolism
Enzymatic metabolism to 5-FU
- In the liver, carboxylesterase hydrolyzes much of the compound to 5’-DFCR
- Cytidine deaminase (in most tissues, including tumors) subsequently converts 5’-DFCR to 5’-DFUR
- Thymidine phosphorylase then hydrolyzes 5’-DFUR to active drug 5-FU
Elimination
Half-life: 0.75 hr (parent capecitabine and 5-FU)
Excretion: urine (95%)
Dialyzable: yes
Pharmacogenomics
Dihydropyrimidine dehydrogenase (DPD), an enzyme encoded by the DPYD gene, is the rate-limiting step in pyrimidine catabolism and deactivates >80% of 5FU standard doses and the 5-FU prodrug capecitabine
Contraindicated in patients with DPD deficiency; causes severe toxicity with conventional doses (ie, grade III/IV toxicity and potentially fatal neutropenia, mucositis, and diarrhea)
Because true DPD deficiency is rare and the clinical implications of partial deficiency are still unclear, screening for mutations before initiating therapy is not warranted
Administration
Oral Administration
Swallow tablets whole with water within 30 minutes after a meal
If tablets must be cut or crushed, this should be done by a professional trained in safe handling of cytotoxic drugs using appropriate equipment and safety procedures
Storage
Store at 25ºC (77ºF); excursions permitted to 15-30ºC (59-86ºF)
Keep container tightly closed
Follow applicable special handling and disposal procedures for cytotoxic drugs

CAPECITABINE - ORAL
(KAP-e-SYE-ta-been)
COMMON BRAND NAME(S): Xeloda
WARNING: People taking capecitabine along with certain "blood thinners" (anticoagulants such as warfarin or phenprocoumon) may have a higher chance of serious, rarely fatal bleeding. Your risk may be higher because you have cancer, or if you are older than 60 years. Bleeding has occurred during treatment and as long as one month after stopping capecitabine.If you are using an anticoagulant, blood lab tests (INR/PT) will be closely checked. Tell your doctor right away if you have any signs of bleeding or bruising (such as bloody/black/tarry stools). You should be tested for a DPD enzyme deficiency before you start treatment with capecitabine. Ask your doctor for more details.
USES: Capecitabine is used to treat breast, colon, or rectal cancer. It works by slowing or stopping the growth of cancer cells.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking capecitabine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth as directed by your doctor, usually 2 times a day; once in the morning and once in the evening. Swallow the tablets whole with a full glass of water (8 ounces/240 milliliters) within 30 minutes after a meal. Do not crush or split the tablets. If you have trouble swallowing the tablets whole, ask your health care professional for advice. Your doctor may direct you to take this medication in a treatment cycle. Carefully follow your doctor's instructions.The dosage is based on your medical condition, body size, and response to treatment. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.
SIDE EFFECTS: Nausea, vomiting, loss of appetite, constipation, tiredness, weakness, headache, dizziness, trouble sleeping, or changes in taste may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Diarrhea is a common side effect of this medication. Drink plenty of fluids unless directed otherwise. Your doctor may also prescribe medication (such as loperamide) to help lessen diarrhea. Vomiting or diarrhea that doesn't stop may result in dehydration. Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual decreased urination, unusual dry mouth/thirst, or dizziness/lightheadedness.Temporary hair loss may occur. Normal hair growth should return after treatment has ended. Also, temporary nail changes may occur.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Stop taking capecitabine and tell your doctor right away if any of these very serious side effects occur: severe nausea/vomiting (vomiting 2 or more times per day, unable to eat or keep food/fluids in your stomach), painful redness/swelling/sores in mouth or on your tongue.Capecitabine may make you develop a skin problem called hand-foot syndrome. To help prevent this, protect your hands and feet from heat or increased pressure. Avoid activities such as using hot dishwater, taking tub baths, jogging, long walks, or using garden or household tools such as screwdrivers. Symptoms may include pain, swelling, redness, blisters, or numbness of the hands/feet. Your doctor may prescribe medication (such as balm) to help with symptoms. If symptoms affect your usual activities, get medical help right away.For men and women of childbearing age, this medication may affect your ability to have children. Ask your doctor for more details.This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infections (such as sore throat that doesn't go away, fever, chills, cough).Tell your doctor right away if you have any serious side effects, including: easy bruising/bleeding, mental/mood changes (such as depression), swelling of the ankles/feet, vision changes, signs of kidney problems (such as change in the amount of urine), yellowing eyes/skin, dark urine.Get medical help right away if you have any very serious side effects, such as: chest/jaw/left arm pain, unusual sweating, fainting, slow/fast/irregular heartbeat.A very serious allergic reaction to this drug is rare.
