Ibruxen 140mg, Ibrutinib Capsules
As an inhibitor of Bruton’s tyrosine kinase (BTK), Ibruxen 140 mg is an oral drug. It is primarily utilized in the treatment of various B-cell malignancies, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), and Waldenström’s macroglobulinemia (WM).
What is Ibrutinib?
Ibruxen 140 mg is a prescription cancer medicine that contains Ibrutinib, a targeted therapy drug used to treat certain types of blood cancers. It is a member of the group of drugs known as Bruton’s Tyrosine Kinase (BTK) inhibitors.
Mechanism of Action:
Ibrutinib exerts its therapeutic effects by irreversibly binding to the BTK enzyme, a crucial component in B-cell receptor signaling. This binding inhibits BTK’s activity, leading to reduced proliferation and survival of malignant B-cells. Additionally, ibrutinib interferes with other signaling pathways, contributing to its anti-cancer effects .
Indications:
Ibruxen 140 mg is indicated for:
- Chronic Lymphocytic Leukemia (CLL)
- Small Lymphocytic Lymphoma (SLL)
- Mantle Cell Lymphoma (MCL)
- Waldenström’s Macroglobulinemia (WM)
- Marginal Zone Lymphoma (MZL)
- Chronic Graft-Versus-Host Disease (cGVHD)
Dosage and Administration:
Standard Dosage:
- For WM and CLL/SLL, 420 mg once daily is the suggested dosage.
- 560 mg once daily is the recommended dosage for MCL.
Management:
- It is recommended to take ibrutinib orally, either with or without food.
- Instead of chewing or crushing the tablets, they should be consumed whole.
Dosage Modifications:
- When used with potent CYP3A inhibitors, the dosage may need to be lowered to 140 mg per day.
- A dose of 280 mg per day may be necessary for moderate CYP3A inhibitors.
Side Effects:
Common adverse effects include:
- Diarrhea
- Fatigue
- Musculoskeletal pain
- Rash
- Upper respiratory tract infections
- Bruising or bleeding
Serious side effects may involve:
- Infections (e.g., pneumonia)
- Cardiac arrhythmias
- Hypertension
- Tumor Lysis Syndrome (TLS)
- Second primary cancers
Storage:
- Ibruxen pills should be kept between 20°C and 25°C (68°F and 77°F) at room temperature.
- To keep it safe from moisture, keep the drug in its original container.
- Make sure children cannot get the medication.
Benefits:
- Targeted therapy with a novel mechanism of action.
- Oral administration offers convenience.
- Demonstrated efficacy in various B-cell malignancies.
- Potential for improved patient outcomes in relapsed or refractory cases.
Prescription:
Ibruxen 140 mg is a prescription-only medication. It should be prescribed by a healthcare professional experienced in the use of anticancer therapies. Regular monitoring and assessment are essential during treatment.
Drug Interactions:
-
CYP3A Inhibitors:
Co-administration with strong CYP3A inhibitors (e.g., ketoconazole) may increase ibrutinib levels, necessitating dose adjustments .
-
CYP3A Inducers:
Drugs like rifampin may decrease ibrutinib levels, potentially reducing its efficacy.
-
Food Interactions:
Grapefruit and Seville oranges can increase ibrutinib concentrations and should be avoided .
