Capecitabine is an oral chemotherapy medication that functions as an antimetabolite to inhibit tumor cell growth.
Capecitabine is an oral chemotherapy agent that belongs to the class of drugs known as antimetabolites. It is designed to interfere with the growth of cancer cells while being taken by mouth in tablet form. In Hong Kong, capecitabine is an approved active ingredient found in several prescription products, including Xeloda and Capnat.
Patients in Hong Kong may encounter capecitabine in the following medicines:
All three are available as oral tablets, usually in multiple strengths to allow doctors to tailor the amount to each individual's treatment plan. Generic versions are typically less expensive, while brand-name products may be preferred in certain hospitals or clinics. Availability can vary between private pharmacies and public hospitals, but each product is regulated by the Hong Kong Department of Health under the Medicines and Poisons Ordinance.
Capecitabine is used in the management of several solid tumours. The main conditions include:
These uses are based on approvals from health authorities in Hong Kong and reflect the drug’s ability to target rapidly dividing cells.
Capecitabine is taken as a pill and travels through the bloodstream to the liver, where it is converted into an inactive form. Enzymes inside tumour tissue then change this intermediate into the active chemotherapy drug 5-fluorouracil (5-FU). The resulting 5-FU blocks the construction of DNA, which cancer cells need to multiply. Because the final conversion occurs mainly inside tumours, the medication aims to limit damage to normal cells while stopping cancer growth. Effects are usually seen within a few days of starting treatment.
These reactions are typical of many chemotherapy agents and often lessen as the body adjusts.
If any of these occur, seek emergency care without delay.
Capecitabine may interact with:
Lifestyle factors, such as excessive sun exposure or operating heavy machinery, should also be considered, as certain side effects (e.g., hand-foot syndrome) can affect skin sensitivity and coordination. For a full interaction list, refer to the specific medication’s patient information leaflet.
Store capecitabine tablets in a dry place at room temperature, away from direct sunlight and moisture. The drug is usually given in cycles-periods of taking the tablets followed by a rest period-to allow the body to recover. Treatment length varies widely depending on the cancer type and the regimen selected by the prescribing physician. Always follow the instructions printed on the product label and the guidance supplied with the specific medication. For detailed usage, dosing, and administration, refer to your particular medicine’s information.
Prodrug: A medication that is inactive until the body changes it into its active form.
Hand-foot syndrome: Redness, swelling, or pain on the palms of the hands or soles of the feet, commonly seen with certain chemotherapy drugs.
Neoplasm: An abnormal growth of tissue, which can be benign (non-cancerous) or malignant (cancerous).
