Introduction

Sunitix (generic name: sunitinib maleate) is a drug used to treat various types of cancer, including renal cell carcinoma, gastrointestinal stromal tumors, and neuroendocrine tumors. It is available in oral pills, and is taken once-daily, usually in the morning.

Uses For Sunitix

Sunitix is used to treat people with renal cell carcinoma, or certain types of tumors of the digestive system (gastrointestinal stromal tumors) or of the hormone-producing cells of the pancreas (pancreatic neuroendocrine tumors).

Mechanism of Action

Sunitix works by blocking proteins in the body (tyrosine kinases) involved in the growth and spread of cancer cells. It works by preventing the growth of new blood vessels that supply cancer cells with the nutrients they need to continue growing, and by blocking signal pathways that trigger cancer cell growth.

How Long Does it Take to Work?

The effects of sunitinib vary from person to person. Some people may experience benefits within 4-6 weeks, while others may not see any effects for several months. Regular monitoring is essential to assess the response to treatment.

Absorption

Sunitix is taken orally, and is quickly and completely absorbed into the bloodstream after ingestion.

Route of Elimination

Sunitix is eliminated from the body mainly through the kidneys.

Dosage

The dose and duration of sunitinib treatment depends on the type and stage of the cancer, and the individual’s response to treatment. The doses for renal cell carcinoma, gastrointestinal stromal tumor, and pancreatic neuroendocrine tumors are 50 mg taken orally once a day for 4 weeks, followed by 2 weeks off. For some types of cancer, the dose may be increased to 75 mg per day.
