Read moreBaritor 2 mg is indicated for the treatment of adult patients with moderate to severely active Rheumatoid Arthritis who have had an inadequate response to one or more tumor necrosis factor (TNF) antagonist therapies. Limitation of Use: Use of Baritor 2 mg in combination with other JAK inhibitors, biologic DMARDs or with potent immunosuppressants such as Azathioprine and cyclosporine is not recommended.
Baritor 2 mg is a Janus kinase (JAK) inhibitor. JAKs are intracellular enzymes which transmit signals arising from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoiesis and immune cell function. Within the signaling pathway, JAKs phosphorylate and activate Signal Transducers and Activators of Transcription (STATs) which modulate intracellular activity including gene expression. Baritor 2 mg modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs.
Dosage & Administration of Baritor 2 mg
The recommended dose of Baritor 2 mg is 2 mg once daily. Baritor 2 mg may be used as monotherapy or in combination with Methotrexate or other DMARDs.
Dosage of Baritor 2 mg
Adult dose: The recommended dose of Baritor 2 mg is 2 mg once daily. It may be used as monotherapy or in combination with Methotrexate or other Disease-modifying antirheumatic drugs (DMARDS). Baritor 2 mg can be given orally with or without food.Pediatric Use: The safety and effectiveness of Baritor 2 mg in pediatric patients have not been established.Geriatric Use: Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection.Hepatic Impairment: No dose adjustment is necessary in patients with mild or moderate hepatic impairment.Renal impairment: Baritor 2 mg is not recommended for use in patients with estimated GFR of less than 60 mL/min/I .73 m2.
Interaction of Baritor 2 mg
Strong OAT3 Inhibitors: Baritor 2 mg exposure is increased when it is co-administered with strong OAT3 inhibitors (such as probenecid).Other JAK Inhibitors or Biologic DMARDs: Baritor 2 mg has not been studied in combination with other JAK inhibitors or with biologic DMARDS.
Anemia: Avoid initiation or interrupt Baritor 2 mg in patients with hemoglobin less than 8 g/dL.
Lymphopenia: Avoid initiation or interrupt Baritor 2 mg in patients with an Absolute Lymphocyte Count less than 500 cells/mm3.
Neutropenia: Avoid initiation or interrupt Baritor 2 mg in patients with an Absolute Neutrophil Count less than 1000 cells/mm3.
Side Effects of Baritor 2 mg
The most commonly reported adverse drug reactions (ADRs) occurring in 2% of patients treated with Baritor 2 mg monotherapy or in combination with conventional synthetic DMARDs were increased LDL cholesterol (33.6%), upper respiratory tract infections (14.7%) and nausea (2.8%).
Pregnancy & Lactation
It is not known if Baritor 2 mg will harm an unborn baby. Because of the potential for serious adverse reactions in nursing infants, advice an Baritor 2 mg treated woman not to breastfeed.
Precautions & Warnings
Serious Infections: Avoid use of Baritor 2 mg in patients with an active, serious infection, including localized infections.
Tuberculosis: Baritor 2 mg should not be given to patients with active TB.
Malignancy and Lymphoproliferative Disorders: Consider the risks and benefits of Baritor 2 mg treatment prior to initiating therapy in patients with a known malignancy other than a successfully treated non-melanoma skin cancer (NMSC) or when considering continuing Baritor 2 mg in patients who develop a malignancy.
Thrombosis: Baritor 2 mg should be used with caution in patients who may be at increased risk of thrombosis.
Gastrointestinal Perforations: Baritor 2 mg should be used with caution in patients who may be at increased risk for gastrointestinal perforation.
To be dispensed only by the prescription of a registered physician.
Overdose Effects of Baritor 2 mg
In case of an overdose, it is recommended that the patient should be monitored for signs and symptoms of adverse reactions. Patients who develop adverse reactions should receive appropriate treatment.
Store at or below 30°C temperature. Keep away from light and wet place. Keep out of reach of children.
Use In Special Populations
Moderate Renal Impairment: Reduce dose to 1 mg once daily.
Mode Of Action
Baritor 2 mg is a selective and reversible inhibitor of Janus kinase JAK1 and JAK2. Janus kinases (JAKs) are enzymes that transduce intracellular signals from cell surface receptors for a number of cytokines and growth factors involved in haematopoiesis, inflammation and immune function. Within the intracellular signalling pathway, JAKs phosphorylate and activate signal transducers and activators of transcription (STATs), which activate gene expression within the cell. Baritor 2 mg modulate these signalling pathways by partially inhibiting JAK1 and JAK2 enzymatic activity, thereby reducing the phosphorylation and activation of STATs.
Baritor 2 mg is contraindicated during pregnancy. No information is available on the presence of Baritor 2 mg in human milk.
