Sunixar 25 Capsule belongs to the class of medications called ‘antineoplastic agents’ used in treating gastrointestinal stromal tumors (cancer of the stomach, bowel, or esophagus) in which patients don’t respond to imatinib (another anticancer agent). It is also used to treat renal carcinoma (kidney cancer) that has spread to other parts of the body and advanced pancreatic neuroendocrine tumors (cancer that has affected hormone-producing cells in the pancreas).

Sunixar 25 Capsule contains sunitinib. It acts by slowing down the growth of cancer cells by two processes. It interferes with the action of a protein that promotes cell division and thereby decreases cancer cell production. It can inhibit a process called angiogenesis, the development of blood supply to the cancer cells. This effect inhibits the nutrient supply to the cancer cells, thereby causing cancer cell death eventually.

Gastrointestinal stromal tumor: It is cancer that affects the stomach and small intestine. It shows no or mild symptoms during the initial stages. It may cause blood in the stool or vomit as the disease progresses. In general, surgery is preferred for the treatment. However, imatinib or sunitinib (targeted therapy) can be given to shrink the tumor or if the tumor cannot be removed by surgery. 

Kidney cancer: It is also called renal cell carcinoma. It is the most common type of cancer seen in adults. Symptoms include red, orange, or pink-colored urine due to the presence of blood in the urine. In advanced kidney cancer (that has spread to other parts of the body), treatment is given to improve the survival rate.

Pancreatic neuroendocrine tumors: It is a type of endocrinal tumor that arises in the pancreas. Symptoms include yellowish skin or whites of the eyes, diarrhea, indigestion, stomach pain, and weight loss. Surgery, hormonal therapy, chemotherapy, and targeted therapy can be given to treat this type of tumor.
