Tofanib XR
Tofanib XR Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Tofanib XR is a brand name. Its generic name is Tofacitinib.
Introduction
Tofanib XR is an inhibitor of the Janus kinase (JAK) family of enzymes. It is used to treat rheumatoid arthritis (RA) and psoriatic arthritis. It works by inhibiting the activation of signal transduction proteins involved in the overproduction of pro-inflammatory proteins. It is classified as a "biologic" medication, meaning that it is made up of genetically engineered proteins.
Uses
Tofanib XR is used to treat adults with active rheumatoid arthritis (RA). It can also be used to treat psoriatic arthritis in adults. Tofanib XR can reduce the signs and symptoms of RA and help improve physical function.
Mechanism of Action
Tofanib XR works by inhibiting the Janus kinase (JAK) family of enzymes. JAKs are involved in the activation of signal transduction proteins involved in the overproduction of pro-inflammatory proteins. By inhibiting the action of the JAKs, tofacitinib decreases the production of these pro-inflammatory proteins, relieving the symptoms of RA and psoriatic arthritis.
How Long Does it Take to Work?
The time it takes for tofacitinib to show its effects varies from person to person. Most patients experience relief of RA symptoms within 2 to 3 weeks of initiation of treatment. This duration may be shorter or longer in some individuals.
Absorption
Tofanib XR is rapidly absorbed after oral consumption with a median of 1 hour. The drug is readily absorbed from the gastrointestinal tract, with no evidence of altered absorption due to food intake.
Route of Elimination
Tofanib XR is primarily eliminated via metabolism in the liver. The metabolites of tofacitinib are excreted via urine and bile.
Dosage
Tofanib XR is available in 5 mg, 10 mg, 15 mg, and 30 mg tablets and is taken orally, usually twice daily. Patients may start with a lower dose and increase it gradually depending on their response and tolerance. The maximum recommended daily dose is 15 mg twice daily. The dose should be reduced in patients with impaired renal function.
Administration
Tofanib XR should be taken orally, with or without food, usually twice daily. It should be taken at the same time each day as prescribed by the physician. It is important to take tofacitinib exactly as prescribed by the doctor.
Side Effects
The common side effects associated with tofacitinib use are gastrointestinal upset, headaches, low blood pressure, and elevated liver enzymes. Serious side effects associated with tofacitinib include increased risk of infection, worsening of the underlying disease, and increased risk of blood clots.
Toxicity
Tofanib XR has not been associated with any reported cases of toxicity in humans. However, due to its mechanism of action, it may lead to increased susceptibility to certain infections.
Precaution
Tofanib XR should be used with caution in patients with impaired renal function. It is important to monitor patients closely for signs and symptoms of infection and worsening of the underlying disease. Patients should be advised to inform their doctor if they develop any signs or symptoms of infection.
