Afinitor Disperz is prescribed for postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer. This type of breast cancer is driven by hormones like estrogen and progesterone but does not overexpress the HER2 protein. 

Afinitor Disperz is typically used in combination with another medication called exemestane after other treatments have failed.

Afinitor Disperz is indicated for the treatment of patients with advanced PNET that cannot be surgically removed or has spread to other parts of the body. Pancreatic neuroendocrine tumors are rare and can be aggressive. 

Afinitor Disperz is used for patients with advanced kidney cancer, also known as renal cell carcinoma (RCC), after other treatments have failed. 

Afinitor Disperz works by inhibiting the mTOR pathway, which is often overactive in kidney cancer cells, leading to uncontrolled cell growth and tumor progression. 

How it works 

Afinitor Disperz inhibits a protein called mammalian target of rapamycin (mTOR), which plays a crucial role in regulating cell growth, proliferation, and survival. 

By blocking the activity of mTOR, Afinitor Disperz helps slow down or stop the growth of cancer cells, thereby reducing the progression of the disease.

Common Side Effects

• Stomatitis (Mouth Sores): These can range from mild discomfort to more severe pain and may affect eating and swallowing. 
• Fatigue: Many patients experience tiredness or weakness, which can affect daily activities. Adequate rest and gentle exercise may help alleviate fatigue.

Patients with liver problems may require dose adjustments or closer monitoring while taking Afinitor Disperz.

Drugs that inhibit the activity of the enzyme CYP3A4 can increase the concentration of Afinitor Disperz in the blood, potentially leading to increased side effects or toxicity. 

Conversely, drugs that induce the activity of CYP3A4 can decrease the concentration of Afinitor Disperz in the blood, reducing its effectiveness. Close monitoring of Afinitor Disperz efficacy is recommended when co-administered with these medications, and dosage adjustments may be necessary.

Consumption of grapefruit or grapefruit juice should be avoided while taking Afinitor Disperz, as it can increase the concentration of the medication in the blood and lead to potentially serious side effects.

The dosage of Afinitor Disperz (everolimus) varies depending on the type of cancer being treated and the individual patient’s health status. For advanced breast cancer, the recommended dose is typically 2.5 mg once daily, taken orally, in combination with exemestane. This regimen is usually continued until disease progression or unacceptable toxicity occurs.

In the case of advanced pancreatic neuroendocrine tumors (PNET), the recommended starting dose is 10 mg once daily, taken orally, without food.
