Mistaurin 25mg Capsule

1. Product Introduction

Mistaurin 25mg Capsule contains Midostaurin, a targeted cancer therapy classified as a multi-kinase inhibitor. Midostaurin interferes with specific enzymes (kinases) responsible for the growth and survival of cancer cells. It plays a vital role in managing certain types of blood cancers by inhibiting mutated proteins that drive cancer progression.

Primarily used to treat acute myeloid leukemia (AML) and systemic mastocytosis, Mistaurin works by blocking FLT3 and other kinases that are abnormally active in these conditions. It is usually prescribed alongside other chemotherapy drugs or as a monotherapy, depending on the specific diagnosis and patient needs.

Mistaurin 25mg Capsule is available by prescription only and should be taken under the supervision of a qualified oncologist or hematologist.

2. Uses of This Medicine

Mistaurin 25mg Capsule is used in the treatment of:

• Acute Myeloid Leukemia (AML):
  For adult patients with FLT3-mutated AML, as detected by an FDA-approved test. It is typically used in combination with standard cytarabine and daunorubicin induction and consolidation chemotherapy.

• Aggressive Systemic Mastocytosis (ASM),

• Systemic Mastocytosis with Associated Hematological Neoplasm (SM-AHN), and

• Mast Cell Leukemia (MCL):
  These are rare blood disorders caused by an overproduction of mast cells. Mistaurin helps in reducing symptoms and mast cell counts in these conditions.

Midostaurin provides a targeted treatment approach, specifically for patients with genetic mutations or protein overexpression that standard chemotherapy may not fully address.

3. Benefits of This Medicine

• Targeted Therapy:
  Mistaurin directly inhibits abnormal FLT3 proteins, effectively halting the rapid growth of leukemia cells, providing a more precise and effective approach to AML treatment.

• Improved Survival Rates:
  Clinical studies have shown that patients treated with Midostaurin alongside chemotherapy have better overall survival compared to chemotherapy alone in FLT3-positive AML.

• Symptom Relief in Mastocytosis:
  For systemic mastocytosis and related disorders, Mistaurin helps reduce the number of mast cells and alleviates symptoms like fatigue, bone pain, itching, and gastrointestinal problems.

• Oral Administration:
  The capsule form allows patients to take the medicine conveniently at home, reducing the need for frequent hospital visits.

• Combination Therapy Compatible:
  Works synergistically with other chemotherapy agents, making it a valuable component of comprehensive cancer care.

4. Side Effects

Like all cancer medications, Mistaurin 25mg Capsule may cause side effects, some of which may require medical attention. Patients are usually monitored regularly to manage and mitigate these effects.

Common Side Effects:

• Nausea and vomiting

• Diarrhea or constipation

• Headache

• Fatigue or weakness

• Loss of appetite

• Upper respiratory tract infections

• Fever (due to low white blood cell count)

Serious Side Effects:

• QT Prolongation: A heart rhythm disorder that may need ECG monitoring.

• Low Blood Cell Counts: Including anemia, neutropenia, and thrombocytopenia—can increase the risk of infection and bleeding.

• Pneumonitis: Lung inflammation presenting as cough, difficulty breathing, or fever.

• Severe Allergic Reactions: Swelling, rash, or breathing difficulty.

Always consult your healthcare provider if you experience any severe or persistent side effects.
