Butinib (Ibrutinib) 140 Mg – 112 Capsules

Description

Butinib (Ibrutinib) 140 mg is a small-molecule inhibitor that targets Bruton’s tyrosine kinase (BTK). It acts by forming a covalent bond with a cysteine ​​residue in the BTK active site, inhibiting enzyme activity. Nonclinical studies have demonstrated that ibrutinib effectively inhibits the proliferation and survival of malignant B cells in vivo. Additionally, it has been shown to inhibit cell migration and substrate adhesion in vitro.

Precautions of Butinib

Hemorrhage: Fatal bleeding events have occurred in patients treated with the medicine. Grade 3 or higher bleeding events (intracranial hemorrhage (including subdural hematoma), gastrointestinal bleeding, hematuria, and post procedural hemorrhage) have occurred in 3% of patients, with fatalities occurring in 0.3% of 1,011 patients exposed to Butinib in clinical trials. Bleeding events of any grade, including bruising and petechiae, occurred in 44% of patients treated with Butinib. Butinib may increase the risk of hemorrhage in patients receiving antiplatelet.

Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with Butinib therapy. Grade 3 or greater infections occurred in 24% of 1,011 patients exposed to Butinib in clinical trials. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with Butinib. Consider prophylaxis according to the standard of care in patients at risk for opportunistic infections. Monitor and assess patients for fever and infection and treat them appropriately.

Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (23%), thrombocytopenia (8%), and anemia (3%) based on laboratory measurements occurred in patients with B-cell malignancies treated with single agent Butinib.

Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0.2% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 4% of 1,011 patients exposed to Butinib inclinical trials. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias. Periodically patients should be monitore clinically for cardiac arrhythmias.

Hypertension:

Hypertension has occurred in 12% of 1,011 patients treated with the drug in clinical trials with a median time to onset of 5 months (range, 0.03 to 22 months). Monitor patients for new-onset hypertension or for hypertension that is not adequately controlled after initiation of Butinib. Adjust existing anti-hypertensive medications and/or initiate anti-hypertensive treatment as appropriate.
