🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Etanercept is a recombinant human tumour necrosis factor receptor fusion protein that acts as a soluble TNF inhibitor. It binds specifically to tumour necrosis factor-alpha (TNF-α) and tumour necrosis factor-beta (lymphotoxin-alpha), preventing them from interacting with cell surface TNF receptors. This blocks the inflammatory cascade that leads to joint destruction and skin inflammation. By neutralising TNF, etanercept reduces the production of other inflammatory cytokines such as interleukin-1 and interleukin-6, decreases adhesion molecule expression, and lowers immune cell recruitment to sites of inflammation.
Mechanism Steps
💡 How to Take intacept 50mg injection
Strength: 50 mg/1 mL single-use prefilled syringe or prefilled pen for subcutaneous injection.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine is 50 mg given once weekly as a subcutaneous injection. For some conditions, a dose of 25 mg twice weekly or 50 mg twice weekly may be used, but this must be determined by a qualified clinician. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and response to treatment. Do not self-administer without proper training. |
| Pediatric Dosage | For polyarticular juvenile idiopathic arthritis in children aged 2 years and older, the dose is based on body weight and is typically 0.8 mg/kg once weekly (maximum 50 mg per week). Pediatric dosing must be determined by a pediatric rheumatologist. Do not use in children under 2 years of age. |
| Elderly Dosage | No specific dose adjustment is required for elderly patients based on age alone. However, elderly patients may be more susceptible to infections and should be monitored closely. Dose must be individualized by a qualified clinician. |
| Renal Impairment | No dose adjustment is generally required for mild to moderate renal impairment. In severe renal impairment, caution is advised and dose may need to be individualized by a qualified clinician. |
| Hepatic Impairment | No dose adjustment is generally required for hepatic impairment. However, caution is advised in patients with severe hepatic impairment or those with hepatitis B, as reactivation can occur. |
| Maximum Daily Dose | The maximum recommended dose is 50 mg per week for most indications, although some regimens may use up to 50 mg twice weekly for a limited period under specialist supervision. Do not exceed the dose prescribed by your doctor. |
