What is the dosage of infliximab treatment?

infliximab Arthritis), Psoriatic Arthritis, Ankylosing Spondylitis, Moderate to Severe Plaque Psoriasis The usage and dosage design reflects a highly individualized and staged strategy, and is usually administered by intravenous drip.

The standard recommended dose is 5 mg/kg body weight each time. The first dose is administered in week 0, followed by another dose in weeks 2 and 6. This stage is called induction therapy, which is used to quickly reduce inflammation and control disease progression. After completing the initial induction, the patient enters the maintenance treatment phase, usually intravenously injected once every 8 weeks, and the dose is still 5 mg/kg. The purpose is to continue the curative effect and avoid recurrence of the disease. If the patient has a good response in the early stage but the effect weakens in the later period, the doctor may increase the dosage of the maintenance period to 10 mg/kg, or shorten the injection interval to every 6 weeks or even every 4 weeks to enhance the efficacy of the drug. Specific adjustments need to be judged based on the patient's weight, disease type, drug response, and whether other immunosuppressants are used in combination.

In addition, the way drugs are used in different indications is also slightly different. For example, in Crohn's disease and ulcerative colitis, in order to pursue rapid induction of remission, the dosing rhythm may be advanced; in rheumatoid arthritis, it is often used in combination with methotrexate to enhance the anti-rheumatic effect. The use of infliximab also requires attention to monitoring and pretreatment measures before and after administration to prevent infusion-related reactions and potential infection risks. Doctors usually conduct basic assessments before administration, including tuberculosis screening, hepatitis B testing, etc., to avoid activation of latent infection due to immunosuppression.

In short, the usage and dosage of infliximab must strictly follow the clinical path and be adjusted based on individual differences. Only long-term standardized management under the guidance of professional physicians can the drug's efficacy be maximized and safety and stability guaranteed.
