Sorafenib NEW

Description: 

Information

Brand Name: Nexavar

Chemical Name: Sorafenib

Type: Tyrosine kinase inhibitor, anti-cancer medication

Uses

Hepatocellular Carcinoma (HCC):

Sorafenib is primarily used to treat hepatocellular carcinoma, which is the most common type of liver cancer. It is usually prescribed for patients with advanced HCC who are not candidates for surgical resection or liver transplantation.

Renal Cell Carcinoma (RCC):

Sorafenib is also approved for the treatment of advanced renal cell carcinoma, a type of kidney cancer. It is used in patients who have failed prior systemic therapy or for those who are not suitable for such treatments.

Thyroid Cancer:

Sorafenib is used to treat differentiated thyroid carcinoma (DTC) that is refractory to radioactive iodine treatment. This includes papillary, follicular, and Hürthle cell thyroid cancers.

Mechanism of Action

Tyrosine Kinase Inhibition: Sorafenib works by inhibiting multiple tyrosine kinases, which are enzymes involved in the signaling pathways that regulate cell division and growth. By blocking these enzymes, Sorafenib interferes with the growth and proliferation of cancer cells.

Anti-Angiogenesis: Sorafenib also inhibits vascular endothelial growth factor receptors (VEGFR) and platelet-derived growth factor receptors (PDGFR), which are involved in the formation of new blood vessels (angiogenesis). By blocking these receptors, Sorafenib reduces the blood supply to tumors, thereby inhibiting their growth.

Precautions

Liver Function: Sorafenib can cause hepatotoxicity, so liver function should be monitored regularly. Dose adjustments may be necessary based on liver function tests.

Cardiovascular Health: Sorafenib can cause hypertension (high blood pressure) and increase the risk of cardiac events. Blood pressure should be monitored regularly, and any cardiac symptoms should be reported immediately.

Bleeding Risk: Sorafenib can increase the risk of bleeding. Patients should be monitored for signs of bleeding, and caution should be exercised in those with bleeding disorders or those taking anticoagulant medications.

Pregnancy and Nursing: Sorafenib can cause harm to a fetus and is not recommended during pregnancy. Women of childbearing potential should use effective contraception. It is also not recommended for use while breastfeeding.

Side Effects

Common Side Effects:

Fatigue

Diarrhea

Hand-foot skin reaction (redness, pain, and swelling of the hands and feet)

Rash

Hypertension (high blood pressure)

Nausea and vomiting

Loss of appetite

Less Common but Serious Side Effects:

Hepatotoxicity (liver damage)

Cardiac issues (e.g., heart attack, heart failure)

Severe hypertension

Gastrointestinal perforation (a hole in the stomach or intestines)

Bleeding complications

Severe skin reactions

Monitoring

Liver Function Tests: Regular liver function tests are crucial to monitor for potential liver toxicity.

Blood Pressure: Regular monitoring of blood pressure is necessary to manage any potential hypertension.

Cardiovascular Monitoring: Patients with a history of cardiovascular disease should be closely monitored for any cardiac-related side effects.

Complete Blood Counts: Regular blood tests to monitor for anemia, leukopenia, and thrombocytopenia are recommended.
