Adalimumab is a recombinant human Ig G1 monoclonal antibody that binds specifically to tumor necrosis factor-alpha (TNF-α) and blocks its interaction with p55 and p75 cell surface TNF receptors. It also modulates biological responses that are induced or regulated by TNF-α, including expression of adhesion molecules, chemotaxis, and pro-inflammatory cytokine release.
Competitive inhibitor of alpha-glucosidase enzymes in the small intestine, delaying the breakdown of complex carbohydrates into monosaccharides and reducing postprandial hyperglycemia.
Rheumatoid arthritis (moderate to severe active, alone or with methotrexate),Juvenile idiopathic arthritis (moderate to active polyarticular, age ≥2 years),Psoriatic arthritis (active, alone or with DMARDs),Ankylosing spondylitis (active),Crohn's disease (moderate to severe, age ≥6 years),Ulcerative colitis (moderate to severe, adults),Plaque psoriasis (moderate to severe chronic, adults),Hidradenitis suppurativa (moderate to severe, adults),Uveitis (non-infectious intermediate, posterior, and panuveitis, adults and children ≥2 years)
Adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus
Subcutaneous injection: 40 mg every other week; for patients with Crohn disease, an initial dose of 160 mg (given as four 40 mg injections in one day or two 40 mg injections per day for two consecutive days) followed by 80 mg at week 2 and 40 mg every other week starting at week 4.
50 mg orally three times daily, titrated to 100 mg three times daily as tolerated, taken at the start of each meal.
Terminal elimination half-life is approximately 14 days (range 10-20 days) in patients receiving 40 mg every other week. This long half-life supports biweekly dosing.
Terminal elimination half-life is approximately 2-3 hours in patients with normal renal function (creatinine clearance >60 m L/min). Clinical context: No accumulation occurs with twice-daily dosing in normal renal function; half-life is prolonged in renal impairment (up to 18 hours in end-stage renal disease).
Adalimumab is a monoclonal antibody; it is not metabolized by cytochrome P450 enzymes. Clearance occurs via catabolism to small peptides and amino acids.
Not metabolized; excreted unchanged primarily in feces (51% as unchanged drug, 35% as metabolites) and urine (2-5% as unchanged drug).
Adalimumab (AMJEVITA) is eliminated primarily via intracellular catabolism, with negligible renal or biliary excretion. No intact drug is excreted in urine. The Fe receptor-mediated recycling contributes to long half-life.
Primarily excreted unchanged in the urine (renal elimination accounts for >95% of absorbed dose). Fecal elimination is negligible (<2%).
Adalimumab is a monoclonal antibody; protein binding is negligible as it is not bound to serum proteins. However, it may bind to soluble TNF-alpha with high affinity.
Protein binding is very low (approximately 5-10%), primarily to albumin, with no significant binding to other plasma proteins.
Volume of distribution (Vd) is approximately 4.7-6.0 L (0.06-0.08 L/kg for a 70 kg adult). This small Vd reflects distribution primarily in the vascular and interstitial spaces, consistent with a large protein.
Volume of distribution is approximately 0.3-0.5 L/kg, indicating distribution mainly in extracellular fluid and minimal tissue binding.
Subcutaneous bioavailability: 64% (range 50-80%) after 40 mg SC injection. No intravenous formulation is approved; absolute bioavailability determined by comparison to IV administration.
Oral bioavailability is <2% for the parent compound due to extensive metabolism by intestinal bacteria; however, the active metabolite (miglitol-like) has high local activity. Systemic absorption is minimal (1-2%), consistent with its site of action in the gut.
No dose adjustment required for any degree of renal impairment.
Contraindicated if GFR < 25 m L/min/1.73 m². No adjustment needed for GFR ≥ 25 m L/min/1.73 m².
No dose adjustment required for any degree of hepatic impairment.
No specific guidelines; use caution in Child-Pugh class B or C due to limited data.
For pediatric patients weighing ≥40 kg: 40 mg subcutaneously every other week; for weight <40 kg: 20 mg subcutaneously every other week.
Not recommended for pediatric patients due to lack of safety and efficacy data.
No specific dose adjustment recommended; use with caution due to higher risk of infections.
Initiate at lowest dose (50 mg three times daily); titrate cautiously due to age-related renal decline.
Increased risk of serious infections leading to hospitalization or death, including tuberculosis (TB), invasive fungal infections, and other opportunistic pathogens. Patients should be tested for latent TB before and during therapy. Malignancies, including lymphoma, have been reported in children and adolescents treated with TNF blockers.
None

Hypoglycemia when used in combination with sulfonylureas or insulin (must be treated with glucose, not sucrose),Gastrointestinal adverse effects (abdominal pain, diarrhea, flatulence) due to undigested carbohydrates fermenting in the colon,Hepatotoxicity (rare, monitor liver enzymes),May cause loss of glycemic control if used with intestinal disorders
Known hypersensitivity to adalimumab or any component of the formulation,Active serious infection including sepsis
Diabetic ketoacidosis,Inflammatory bowel disease,Colonic ulceration,Partial intestinal obstruction,Predisposition to intestinal obstruction,Chronic intestinal diseases associated with marked disorders of digestion or absorption,Cirrhosis,Hypersensitivity to miglitol
No specific food interactions. No dietary restrictions required.
Avoid high-sucrose or fructose-containing foods and drinks as GLYSET inhibits the digestion of sucrose, leading to increased fermentation and gastrointestinal distress. Complex carbohydrates (starches) are affected; simple sugars like glucose are not.
Amjevita (adalimumab) is an Ig G1 monoclonal antibody that crosses the placenta during the third trimester, with highest fetal exposure in the third trimester. In the first and second trimesters, placental transfer is limited. Available data from the OTIS autoimmune diseases in pregnancy study and other cohort studies do not indicate a substantially increased risk of major birth defects or miscarriage with adalimumab exposure during pregnancy. However, there is a potential risk of immunosuppression in the neonate, including increased risk of infections, if the mother is exposed during the second and third trimesters. Infants should not be vaccinated with live vaccines for at least 5 months after maternal last dose.
Pregnancy Category B. No evidence of fetal harm in animal studies; no adequate human studies in first trimester. Use only if clearly needed.
Adalimumab is excreted in breast milk in low concentrations. The milk-to-plasma ratio is approximately 0.04. Limited data indicate that infants are exposed to less than 1% of the maternal dose, and no adverse effects have been reported in breastfed infants. Because adalimumab is a large protein, it undergoes proteolysis in the infant's gastrointestinal tract and is not systemically absorbed. Therefore, breastfeeding is considered compatible with adalimumab therapy.
Excreted in human milk; M/P ratio unknown. Caution in nursing mothers due to potential for GI effects in infants.
During pregnancy, adalimumab clearance may increase, especially in the third trimester, leading to lower trough concentrations. However, no dose adjustment is routinely recommended due to lack of data showing altered clinical outcomes. Therapeutic drug monitoring is not standard, but if disease activity increases, consider modifying the dose or frequency as per non-pregnant guidelines. Postpartum, clearance returns to prepregnancy levels, so doses should be adjusted back to prepregnancy regimen if modified.
No dose adjustment recommended based on pharmacokinetic data; monitor glycemic control closely and adjust as needed.
AMJEVITA (adalimumab-atto) is a biosimilar to Humira. Administer subcutaneously; rotate injection sites. Do not administer live vaccines. Screen for TB and hepatitis B before initiation. Consider withholding for serious infections. Monitor for allergic reactions and blood dyscrasias.
GLYSET (miglitol) is an alpha-glucosidase inhibitor that delays carbohydrate digestion, reducing postprandial hyperglycemia. It is not effective for fasting hyperglycemia and should not be used as monotherapy for type 1 diabetes or DKA. Monitor liver function tests; rare hepatotoxicity reported. Avoid in patients with inflammatory bowel disease or intestinal obstruction.
Store in refrigerator, do not freeze; protect from light.,Inject at room temperature; allow to sit out 15-30 minutes.,Rotate injection sites; avoid tender, bruised, or scarred skin.,Report signs of infection (fever, chills, cough) or allergic reaction immediately.,Do not receive live vaccines while on this medication.,Inform all healthcare providers of your use of AMJEVITA.
Take with the first bite of each main meal to delay carbohydrate absorption.,Common side effects include flatulence, diarrhea, and abdominal discomfort, which often improve over time.,If hypoglycemia occurs, use glucose tablets or milk, not sucrose or fruit juice, as GLYSET prevents sucrose breakdown.,Monitor blood glucose regularly, especially when starting or changing dose.,Do not skip meals; take medication exactly as prescribed.
