Kineret

Kineret Uses, Dosage, Side Effects, Food Interaction and all others data.

Kineret is a recombinant, nonglycosylated human interleukin-1 receptor antagonist (IL-1Ra). The difference between anakinra and the native human IL-1Ra is that anakinra has an extra methionine residue at the amino terminus. It is manufactured by using the E. coli expression system. Kineret is composed of 153 amino acid residues. FDA approved on November 14, 2001.

Used to treat rheumatoid arthritis, Kineret blocks the biologic activity of IL-1 by competitively inhibiting IL-1 binding to the interleukin-1 type I receptor (IL-1RI), which is expressed in a wide variety of tissues and organs. IL-1 production is induced in response to inflammatory stimuli and mediates various physiologic responses including inflammatory and immunological responses. Patients with rheumatoid arthritis have elevated levels of IL-1. The levels of the naturally occurring IL-1Ra in synovium and synovial fluid from rheumatoid arthritis (RA) patients are not sufficient to compete with the elevated amount of locally produced IL-1. Increasing the levels of IL-1Ra by artificial means reduces the negative effects (cartilage degradation, bone resorption) of IL-1.

Uses

Kineret is a recombinant form of human interleukin-1 receptor antagonist used in the treatment of rheumatoid arthritis and neonatal-onset multisystem inflammatory disease.

For the treatment of adult rheumatoid arthritis and treatment of Neonatal-Onset Multisystem Inflammatory Disease (NOMID).

Kineret is also used to associated treatment for these conditions: Juvenile Idiopathic Arthritis (JIA), Neonatal-Onset Multisystem Inflammatory Disease (NOMID), Moderate Rheumatoid arthritis, Recurrent Pericarditis, Severe Rheumatoid arthritis

How Kineret works

Kineret binds competitively to the Interleukin-1 type I receptor (IL-1RI), thereby inhibiting the action of elevated levels IL-1 which normally can lead to cartilage degradation and bone resorption.

Toxicity

Most common adverse reactions (incidence ≥ 5%) are injection site reaction, worsening of rheumatoid arthritis, upper respiratory tract infection, headache, nausea, diarrhea, sinusitis, arthralgia, flu like-symptoms, and abdominal pain when anakinra is used in RA patients. In NOMID patients, the most common AEs during the first 6 months of treatment (incidence >10%) are injection site reaction, headache, vomiting, arthralgia, pyrexia, and nasopharyngitis.

Food Interaction

No interactions found.

Kineret Disease Interaction

Major: infections, renal deficiency, tuberculosisModerate: liver disease, neutropenia

Elimination Route

When a 70 mg subcutaneous bolus injection is given to healthy subjects, the absolute bioavailability is 95%. Accumulation does not occur following daily subcutaneous doses. Tmax, SubQ, 1-2 mg/kg, healthy subjects = 3-7 hours; Cmax, SubQ, 3 mg/kg once daily, NOMID patients = 3628 ng/mL.
