Tegafur

Introduction

Tegafur is an anti-cancer medication classified as an antimetabolite. It is a prodrug of 5-fluorouracil (5-FU), meaning it is converted into its active form in the body to exert its therapeutic effects. Tegafur is primarily used in the treatment of solid tumors such as colorectal, breast, pancreatic, and gastric cancers. It is often combined with other chemotherapy agents to enhance efficacy and reduce toxicity. Tegafur works by inhibiting DNA synthesis in rapidly growing cancer cells, thereby slowing or stopping their growth and spread. It is administered under medical supervision due to its potent effects.

Uses of Tegafur

• Treatment of colorectal cancer
• Management of breast cancer
• Therapy for pancreatic cancer
• Used in stomach (gastric) cancer treatment
• Occasionally used in head and neck cancers

How Tegafur Works

Tegafur is converted in the body into 5-fluorouracil (5-FU), which interferes with DNA synthesis in cancer cells. This disruption stops the cells from dividing and growing, ultimately leading to their death. The selective action of Tegafur targets fast-growing tumor cells more effectively than normal tissues.

Benefits of Tegafur

• Effective against various types of solid tumors
• Often used in combination for better therapeutic outcomes
• Oral formulation available for ease of administration
• Slows tumor growth and prevents cancer spread
• Can improve survival and quality of life in cancer patients

How to Take Tegafur

Tegafur should be taken exactly as prescribed by your oncologist. It may be taken orally in capsule form, often as part of a combination regimen with other drugs. The dose and duration depend on your type of cancer, response to treatment, and overall health condition. It is important not to skip doses or alter the schedule without medical advice. Regular blood tests are essential during treatment to monitor side effects and effectiveness.
