🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively inhibiting Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2) enzymes. These enzymes are part of the JAK-STAT signaling pathway, which transmits signals from cytokines and growth factors to the cell nucleus, influencing gene expression. In myelofibrosis and polycythemia vera, abnormal activation of this pathway leads to excessive blood cell production and release of inflammatory cytokines. By blocking JAK1 and JAK2, this medicine reduces the phosphorylation of STAT proteins, thereby decreasing abnormal cell proliferation and inflammation. This results in reduced spleen size and improvement in constitutional symptoms.
Mechanism Steps
💡 How to Take jakavi 15mg tablet
Strength: 15 mg immediate-release tablet
Dosage Information
| Adult Dosage | The recommended starting dose of this medicine for myelofibrosis is 15 mg or 20 mg orally twice daily, depending on platelet counts. For polycythemia vera, the starting dose is 10 mg twice daily. For graft-versus-host disease, the dose is 5 mg twice daily. Dose adjustments are required based on blood counts, renal and hepatic function, and concomitant medications. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | No specific dose adjustment is recommended for elderly patients based solely on age. However, elderly patients may be more sensitive to the effects of this medicine, particularly myelosuppression and infections. Dose should be individualized based on renal and hepatic function and overall health status. |
| Renal Impairment | For patients with moderate renal impairment (creatinine clearance 30-59 mL/min), the starting dose should be reduced by 50% for myelofibrosis and polycythemia vera. For severe renal impairment (creatinine clearance <30 mL/min), the starting dose should be reduced by 50% and used with caution. Avoid use in patients with end-stage renal disease on dialysis. |
| Hepatic Impairment | For patients with mild or moderate hepatic impairment (Child-Pugh A or B), the starting dose should be reduced by 50% for myelofibrosis and polycythemia vera. This medicine is contraindicated in patients with severe hepatic impairment (Child-Pugh C). |
| Maximum Daily Dose | The maximum recommended daily dose is 25 mg twice daily for myelofibrosis, but this must be individualized. Do not exceed the dose prescribed by your doctor. |
