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.
- Diarrhea: A common gastrointestinal side effect that can lead to dehydration if not managed properly. Drinking plenty of fluids and avoiding spicy or greasy foods may help alleviate diarrhea.
- Rash: Some patients may develop a rash or skin irritation, which can be itchy or uncomfortable. Inform your healthcare provider if you experience any skin changes.
- Decreased Appetite: Loss of appetite or changes in taste sensation can occur, leading to weight loss or malnutrition.
Serious Side Effects
- Lung or Breathing Problems: Symptoms may include cough, shortness of breath, or difficulty breathing. Seek immediate medical attention if you experience any respiratory symptoms.
- Infections: Afinitor Disperz can weaken the immune system, increasing the risk of infections.
- Kidney Problems: This medication can affect kidney function, leading to changes in urine output or swelling in the legs and ankles.
- High Blood Sugar Levels: Afinitor Disperz may cause hyperglycemia, leading to increased thirst, frequent urination, and fatigue. Patients with diabetes should closely monitor their blood sugar levels and adjust their treatment as needed.
It’s essential for patients to discuss any concerns or side effects with their healthcare provider to ensure appropriate management and support during Afinitor Disperz treatment.
Afinitor Disperz can weaken the immune system, increasing the risk of infections. Patients should avoid close contact with individuals who are sick and practice good hygiene, including regular handwashing.
Afinitor Disperz can affect kidney function, so regular monitoring of kidney function tests is necessary. Patients with pre-existing kidney problems may require dose adjustments or closer monitoring.
Afinitor Disperz may cause lung or breathing problems, such as cough or difficulty breathing. Patients should inform their healthcare provider if they experience any respiratory symptoms.
This medication can increase blood sugar levels, so patients with diabetes should monitor their blood sugar levels closely and adjust their treatment regimen as needed.
Some patients may experience severe allergic reactions to Afinitor Disperz, characterized by swelling of the face, lips, or throat, difficulty breathing, or skin rash. Patients should seek immediate medical attention if they develop any signs of an allergic reaction.
Afinitor Disperz may slow down the process of wound healing. Patients undergoing surgery or with open wounds should inform their healthcare provider before starting treatment.
Afinitor Disperz may cause harm to an unborn baby if used during pregnancy. Women of childbearing age should use effective contraception during treatment and for a period after discontinuation of therapy.
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.
Patients should always consult their healthcare provider or pharmacist if they have any questions or concerns about potential drug interactions with Afinitor Disperz. It’s essential to follow their recommendations to ensure safe and effective treatment.
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.
