Read moreRuxolitinib is a Janus kinase (JAK) inhibitor, which is indicated for atopic dermatitis and vitiligo.Atopic Dermatitis: Ruxolitinib cream is used in the topical short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis in non-immunocompro-mised adult and pediatric patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.Vitiligo: Ruxolitinib cream is used in the topical treatment of nonsegmental vitiligo in adult and pediatric patients 12 years of age and older.

Rutinib 0.015 | PHARMACOLOGY

Ruxolitinib, a Janus kinase (JAK) inhibitor, inhibits JAK1 and JAK2 which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of STATs (signal transducers and activators of transcription) to cytokine receptors, activation and subsequent localization of STATs to the nucleus leading to modulation of gene expression. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness is not currently known.Absorption: Plasma concentrations of Ruxolitinib were quantifiable in all subjects. There is no evidence of Ruxolitinib accumulation after daily application of Ruxolitinib for 28 days in subjects with atopic dermatitis.Distribution: Plasma protein binding is approximately 97%.Elimination: The mean terminal half-life of Ruxolitinib following topical application of Ruxolitinib is approximately 116 hours.Metabolism: Ruxolitinib is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9 in vitro.Excretion: Ruxolitinib and its metabolites are primarily excreted by urine (74%) and feces (22%). Less than 1% is excreted as unchanged drug.

Rutinib 0.015 | DOSAGE & ADMINISTRATION

Administration Instruction: Ruxolitinib cream should not use more than 60 gram per week or 100 gram per 2 weeks. It is for topical use only. It is not for intraocular, oral, or intravaginal use.Recommended Dosage for Atopic Dermatitis: Patients should apply a thin layer of Ruxolitinib twice daily to affected areas of up to 20% body surface area. When signs and symptoms (e.g., itch, rash, and redness) of atopic dermatitis resolve it should be stopped. If signs and symptoms do not improve within 8 weeks, patients should be re-examined by registered doctor.Recommended Dosage for Nonseg-mental Vitiligo: Patients should apply a thin layer of Ruxolitinib twice daily to affected areas of up to 10% body surface area. Satisfactory patient response may require treatment with Ruxolitinib for more than 24 weeks. If the patient does not find the repigmentation meaningful by 24 weeks, the patient should be re-evaluated by registered doctor.USE IN CHILDREN: The safety and effectiveness of Ruxolitinib in pediatric patients younger than 12 years of age with atopic dermatitis and nonsegmental vitiligo have not been established.

Rutinib 0.015 | DRUG INTERACTIONS

Ruxolitinib is known to be a substrate for cytochrome P450 3A4 (CYP3A4). Inhibitors of CYP3A4 may increase Ruxolitinib systemic concentrations whereas inducers of CYP3A4 may decrease Ruxolitinib systemic concentrations.Strong Inhibitors of CYP3A4: Concomi- tant use of Ruxolitinib should avoid with strong inhibitors of CYP3A4 as there is a potential to increase the systemic exposure of Ruxolitinib and could increase the risk of Ruxolitinib adverse reactions.

Rutinib 0.015 | SIDE EFFECTS

In atopic dermatitis, the most common side effects are nasopharyngitis, diarrhea, bronchitis, ear infection, eosinophil count increased, urticaria, folliculitis, tonsillitis, and rhinorrhea.In nonsegmental vitiligo, the most common side effects are application site acne, application site pruritus, nasopharyngitis, headache, urinary tract infection, application site erythema, and pyrexia.

Rutinib 0.015 | USE DURING PREGNANCY AND LACTATION

Because of the serious adverse findings in adults, including risks of serious infections, thrombocytopenia, anemia, and neutropenia, women should not breastfeed during treatment with Ruxolitinib and for approximately four weeks after the last dose.

Rutinib 0.015 | PRECAUTIONS & WARNINGS

Serious Infections: Use of Ruxolitinib should avoid in patients with an active, serious infection, including localized infections. If a serious infection develops, interrupt Ruxolitinib until the infection is controlled. The risks and benefits of treatment with Ruxolitinib should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Ruxolitinib.Mortality: In rheumatoid arthritis (RA) patients 50 years of age and older with at least one cardiovascular risk factor comparing an oral JAK inhibitor to tumor necrosis factor (TNF) blocker treatment, a higher rate of all-cause mortality, including sudden cardiovascular death, was observed with the JAK inhibitor.Non-melanoma Skin Cancers: Non-mel-anoma skin cancers including basal cell and squamous cell carcinoma can be occurred in patients treated with Ruxolitinib. Periodic skin examinations should perform during Ruxolitinib treatment. Exposure to sunlight and UV light should be limited by wearing protective clothing and using broad-spectrum sunscreen.Major Adverse Cardiovascular Events (MACE): Patients who are current or past smokers are at additional increased risk of Major Adverse Cardiovascular Events. Patients who have experienced a myocar- dial infarction or stroke, Ruxolitinib should be discontinued.Thrombosis: Thromboembolic events were observed in trials with Ruxolitinib. If symptoms of thrombosis occur, Ruxolitinib should be discontinued and treat appropriately.Thrombocytopenia, Anemia, and Neutropenia: Thrombocytopenia, anemia, and neutropenia can be occurred. Perform CBC monitoring as clinically indicated.
