Actemra IV Infusion 80 mg/4 ml
Actemra IV Infusion 80 mg/4 ml Uses, Dosage, Side Effects, Food Interaction and all others data.
Actemra IV Infusion 80 mg/4 ml is a recombinant humanized anti-human interleukin 6 (IL 6) receptor monoclonal antibody of the immunoglobulin (Ig) IgG1 subclass. Actemra IV Infusion 80 mg/4 ml binds specifically to both soluble and membrane-bound IL 6 receptors (sIL 6R and mIL 6R), and has been shown to inhibit sIL 6R and mIL 6R-mediated signaling. Interleukin-6 is a multi-functional cytokine, produced by a variety of cell types involved in local paracrine function as well as regulation of systemic physiological and pathological processes eg, induction of immunoglobulin secretion, T-cell activation, induction of hepatic acute phase proteins and stimulation of haematopoiesis. Interleukin-6 has been implicated in the pathogenesis of diseases including inflammatory diseases, osteoporosis and neoplasia. The possibility exists for tocilizumab to affect host defences against infections and malignancies. The role of IL-6 receptor inhibition in the development of malignancies is not known.
Actemra IV Infusion 80 mg/4 ml is an IL-6 inhibiting monoclonal antibody used to treat autoimmune and inflammatory conditions. Actemra IV Infusion 80 mg/4 ml has a long duration of action as it is generally given every 4 weeks and has a wide therapeutic index. Patients should be counselled regarding the risk of infections, GI perforation, and hepatotoxicity.

How Actemra IV Infusion 80 mg/4 ml works
Interleukin 6 (IL-6) is a pro-inflammatory cytokine produced by cells including T-cells, B-cells, lymphocytes, monocytes, fibroblasts. IL-6 rapidly induces C-reactive protein, serum amyloid A, fibrinogen, haptoglobin, and α-1-antichymotrypsin while inhibiting production of fibronectin, albumin, and transferrin. IL-6 also induces antibody production, induces cytotoxic T-cell differentiation, and inhibits regulatory T-cell differentiation. Actemra IV Infusion 80 mg/4 ml binds soluble and membrane bound IL-6 receptors, preventing IL-6 mediated inflammation.
Dosage
Actemra IV Infusion 80 mg/4 ml dosage
General (IV or SC Injection): Substitution by any other biological medicinal product requires the consent of the prescribing physician.
For adult patients with RA, tocilizumab may be administered as an IV infusion or a SC injection. For patients with pJIA and sJIA, tocilizumab is administered as an IV infusion.
Actemra IV Infusion 80 mg/4 ml IV formulation should be diluted by a healthcare professional with sterile 0.9% w/v sodium chloride solution using aseptic technique (see Caution for Usage).
Actemra IV Infusion 80 mg/4 ml is recommended for IV infusion over 1 hr.
Actemra IV Infusion 80 mg/4 ml SC formulation is administered with a single-use PFS+NSD or pre-filled pen. The 1st injection should be performed under the supervision of a qualified healthcare professional. The recommended injection sites (abdomen, thigh and upper arm) should be rotated and injections should never be given into moles, scars or areas where the skin is tender, bruised, red, hard or not intact.
SC Injection: Adults: Rheumatoid Arthritis (RA): Recommended Dose: 162 mg given once every week as a SC injection. Actemra IV Infusion 80 mg/4 ml can be used alone or in combination with MTX and/or other DMARDs.
Patients transitioning from tocilizumab IV therapy to SC administration should administer the 1st SC dose at the time of the next scheduled IV dose under the supervision of a qualified healthcare professional.
Actemra IV Infusion 80 mg/4 ml SC formulation is not intended for IV administration. Assess suitability of patient for SC home use and instruct patients to inform a healthcare professional if they experience symptoms of allergic reaction before administering the next dose. Patients should seek immediate medical attention if developing symptoms of serious allergic reactions
Side Effects
Rheumatoid Arthritis: Patients Treated with Subcutaneous Actemra IV Infusion 80 mg/4 ml: The safety of SC tocilizumab in RA was study in SC-I. The study compared the efficacy and safety of tocilizumab 162 mg administered every week SC versus 8 mg/kg IV in 1,262 subjects with adult RA. All patients in the study received background non-biologic DMARD(s). The safety and immunogenicity observed for tocilizumab administered SC was consistent with the known safety profile of tocilizumab IV and no new or unexpected adverse drug reactions were observed (see Table 7). A higher frequency of injection site reactions was observed in the SC arms compared with placebo SC injections in the IV arms
Toxicity
Data regarding overdoses of tocilizumab are not readily available. Patients experiencing an overdose may develop neutropenia. In case of overdose, monitor patients for signs of adverse reactions and provide symptomatic and supportive treatment.
Precaution
Serious infections leading to hospitalization or death (ie, tuberculosis; bacterial, invasive fungal, viral, or other opportunistic infections) have occurred with use Stop therapy if serious infection occurs; can restart if infection is controlled Test for latent tuberculosis before initiating; if positive, initiate tuberculosis therapy before starting tocilizumab. Continue to monitor all patients for active tuberculosis during therapy
Interaction
Interactions with Other Medicinal Products and Other Forms of Interaction: Population pharmacokinetic analyses did not detect any effect of MTX, nonsteroidal anti-inflammatory drugs or corticosteroids on tocilizumab clearance.
Concomitant administration of a single dose of 10 mg/kg tocilizumab with 10-25 mg MTX once weekly had no clinically significant effect on MTX exposure.
Actemra IV Infusion 80 mg/4 ml has not been studied in combination with other biological DMARDs.
The expression of hepatic CYP450 enzymes is suppressed by cytokines, eg, IL-6, that stimulate chronic inflammation. Thus, CYP450 expression may be reversed when potent cytokine inhibitory therapy, eg, tocilizumab is introduced.
In vitro studies with cultured human hepatocytes demonstrated that IL-6 caused a reduction in CYP1A2, CYP2C9, CYP2C19 and CYP3A4 enzyme expression. Actemra IV Infusion 80 mg/4 ml normalizes expression of these enzymes. The effect of tocilizumab on CYP enzymes (except CYP2C19 and CYP2D6) is clinically relevant for CYP450 substrates with a narrow therapeutic index and/or where the dose is individually adjusted.
In a study in RA patients, levels of simvastatin (CYP3A4) were decreased by 57% one week following a single dose of tocilizumab, to the level similar or slightly higher than those observed in healthy subjects.
When starting or stopping therapy with tocilizumab, patients taking medicinal products, which are individually dose-adjusted and are metabolised via CYP450 3A4, 1A2, or 2C9 (eg, atorvastatin, calcium channel blockers, theophylline, warfarin, phenytoin, ciclosporin or benzodiazepines) should be monitored as doses of these products may need to be adjusted to maintain their therapeutic effect. Given its long elimination half-life (t½), the effect of tocilizumab on CYP450 enzyme activity may persist for several weeks after stopping therapy.
