Lenalidomid

Introduction: What is Lenalidomide?

Lenalidomide is a medication primarily used in the treatment of certain types of blood cancers, including multiple myeloma and certain types of lymphoma. It belongs to a class of drugs known as immunomodulatory agents, which help to enhance the immune system's ability to fight cancer. Lenalidomide is often prescribed when other treatments have failed or in combination with other therapies to improve outcomes for patients.

Uses of Lenalidomide

Lenalidomide is approved for several medical uses, including:

• Mnohopočetný myelóm: It is commonly used in patients who have received at least one prior therapy.
• Myelodysplastické syndrómy (MDS): Specifically for patients with deletion of chromosome 5q.
• Lymfóm z plášťových buniek: Used in patients who have received at least one prior therapy.
• Chronická lymfocytová leukémia (CLL): Often in combination with other medications.

Ako to funguje

Lenalidomide works by modulating the immune system and directly affecting cancer cells. It enhances the body's immune response against tumors, inhibits the growth of blood vessels that supply tumors (antiangiogenesis), and induces apoptosis, or programmed cell death, in cancer cells. In simpler terms, it helps the body recognize and fight cancer more effectively while also cutting off the nutrients that tumors need to grow.

Dávkovanie a spôsob podávania

Lenalidomide is typically administered in tablet form. The standard adult dosage varies based on the condition being treated:

• Mnohopočetný myelóm: Usually, 25 mg once daily for 21 days of a 28-day cycle.
• Myelodysplastické syndrómy: Generally, 10 mg once daily.
• Lymfóm z plášťových buniek: Often, 25 mg once daily for 21 days of a 28-day cycle.

For pediatric patients, the dosage is determined by a healthcare provider based on weight and specific medical conditions. It is crucial to follow the prescribed regimen and not to adjust the dose without consulting a doctor.
