Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Acarbose is a complex oligosaccharide that competitively and reversibly inhibits α-glucosidase enzymes in the brush border of the small intestine. This delays the digestion and absorption of complex carbohydrates and disaccharides, thereby reducing postprandial hyperglycemia.
Adalimumab is a recombinant human monoclonal antibody that binds to tumor necrosis factor-alpha (TNFα) and blocks its interaction with p55 and p75 cell surface TNF receptors. It also modulates biological responses induced or regulated by TNFα, including adhesion molecules, chemotaxis, and matrix metalloproteinases.

Initial: 25 mg orally 3 times daily with first bite of each main meal; maintenance: 50-100 mg 3 times daily; max 100 mg 3 times daily.
Adalimumab 40 mg subcutaneously every other week, with or without methotrexate, for rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. For ulcerative colitis and hidradenitis suppurativa, day 1: 160 mg (four 40 mg injections in one day or two 40 mg injections per day for two days), day 15: 80 mg, then 40 mg every other week starting day 29. For uveitis, 40 mg every other week.
Terminal elimination half-life is approximately 2.5 to 3 hours for the parent compound, but the drug acts locally in the GI tract; systemic half-life is not clinically relevant for its pharmacodynamic effect.
Approximately 14 days (range 10–20 days) following subcutaneous administration; supports every-other-week dosing.
Acarbose is metabolized exclusively within the gastrointestinal tract, primarily by intestinal bacteria and digestive enzymes. Approximately 35% of the dose is absorbed as metabolites, which are excreted via the kidneys. The parent drug is not significantly metabolized by hepatic enzymes.
Adalimumab is a monoclonal antibody; it is degraded by proteolytic enzymes into small peptides and amino acids. No specific metabolic pathways or CYP450 enzymes involved.
Primarily excreted unchanged in feces (approximately 50% of an oral dose) and as metabolites via the gastrointestinal tract; less than 2% of the dose is recovered in urine as active drug or metabolites. Renal excretion is minimal.
Primarily eliminated via intracellular catabolism; no significant renal or biliary elimination of intact adalimumab.
Negligible to low protein binding; less than 1-2% bound to plasma proteins, primarily albumin.
Adalimumab binds specifically to soluble and membrane-bound TNF-alpha; does not bind to other serum proteins; binding to specific target is high affinity but no general protein binding data reported.
Volume of distribution is not well defined due to minimal systemic absorption; estimated to be less than 0.3 L/kg, reflecting limited distribution beyond the gastrointestinal lumen.
Approximately 4.7–6.0 L (0.07–0.09 L/kg for a 70 kg adult); indicates distribution primarily within the vascular and interstitial spaces.
Oral: Systemic bioavailability is very low (approximately 0.5-2%) due to local action in the GI tract and minimal absorption. The drug acts locally in the intestine; systemic levels are negligible.
Subcutaneous: 64% (absolute bioavailability).
No specific dose adjustment required for GFR ≥25 m L/min; contraindicated in GFR <25 m L/min (creatinine clearance <25 m L/min).
No dose adjustment required for mild to moderate renal impairment. Not studied in severe renal impairment.
No specific dose adjustment for mild-to-moderate hepatic impairment; contraindicated in severe hepatic impairment (Child-Pugh class C).
No dose adjustment recommended. Not studied in patients with hepatic impairment.
Not recommended for use in pediatric patients; safety and efficacy not established.
For juvenile idiopathic arthritis (2 years and older): 10-30 mg subcutaneously every other week (10 mg if <15 kg, 20 mg if 15-30 kg, 40 mg if ≥30 kg). For pediatric plaque psoriasis (4 years and older): weight-based dosing with maximum 40 mg starting dose, then 0.8 mg/kg up to 40 mg every other week. For pediatric hidradenitis suppurativa (12 years and older): 40 mg every other week.
Initiate at the lowest dose (25 mg 3 times daily); titrate slowly based on tolerance and glycemic control, as elderly patients may have reduced renal function and higher risk of gastrointestinal adverse effects.
No specific dose adjustment. Use with caution due to increased risk of infections. Monitor renal and hepatic function.
None
Serious infections: Increased risk of serious infections leading to hospitalization or death, including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections due to opportunistic pathogens. Discontinue if serious infection develops. Test for latent TB prior to initiation; treat latent TB before use. Lymphoma and other malignancies: Malignancies, some fatal, have been reported in children and adolescents treated with TNF blockers, including adalimumab. Hepatosplenic T-cell lymphoma (HSTCL) has occurred in adolescent and young adults with inflammatory bowel disease treated with TNF blockers.
Risk of hepatotoxicity: rare cases of severe hepatocellular injury, including fulminant hepatitis, reported, especially at higher doses (≥300 mg/day); monitor liver enzymes periodically.,Use with caution in patients with renal impairment (e GFR <25 m L/min/1.73 m²): insufficient data; avoid use.,May cause hypoglycemia when used in combination with sulfonylureas or insulin; treat hypoglycemia with oral glucose (dextrose) rather than sucrose (acarbose inhibits sucrose digestion).,Gastrointestinal adverse effects (flatulence, diarrhea, abdominal pain) are common due to undigested carbohydrate fermentation in the colon; may subside with continued use.,Acute porphyria: acarbose has been associated with acute attacks in susceptible patients.

Acarbose delays digestion of complex carbohydrates and sucrose. To reduce gastrointestinal side effects, avoid high-sucrose foods and drinks. Simple sugars like glucose and fructose can still be absorbed and used to treat hypoglycemia. Alcohol may increase the risk of hypoglycemia when combined with acarbose, especially if taken with other antidiabetic agents.
No significant food interactions reported. Avoid alcohol if liver function is compromised.
Acarbose is classified as FDA Pregnancy Category B. No evidence of teratogenicity in animal studies; limited human data. Minimal systemic absorption (<2%) suggests low fetal exposure. Risk cannot be excluded in first trimester. Second and third trimester: no known fetal risks, but use only if clearly needed.
CYLTEZO (adalimumab-adaz) is a TNF-alpha inhibitor. Human data on teratogenicity are limited; however, large cohort studies do not indicate a significant increase in major birth defects. Theoretical risk of harm to the fetus due to TNF inhibition; however, placental transfer is minimal during first trimester but increases in second and third trimester. There is evidence of increased risk of infections in neonates exposed in utero during later pregnancy. Therefore, use is not recommended in the third trimester unless clearly needed.
Acarbose is excreted into breast milk in negligible amounts due to low oral bioavailability and high molecular weight. M/P ratio not established. Considered compatible with breastfeeding; monitor infant for gastrointestinal effects (e.g., flatulence, diarrhea).
Adalimumab is excreted in human milk in low amounts; M/P ratio not established for adalimumab-adaz specifically. The molecular weight suggests it is unlikely to be absorbed by the infant in significant amounts. Expert consensus generally considers TNF-alpha inhibitors compatible with breastfeeding, but caution is advised. Monitor infant for potential adverse effects such as increased risk of infections or hypersensitivity.
No dose adjustment required. Pharmacokinetics not significantly altered in pregnancy due to minimal systemic absorption. Initiate at 25 mg three times daily with meals; titrate based on 1-hour postprandial glucose levels.
Pharmacokinetic changes in pregnancy include increased volume of distribution and clearance, potentially requiring dose adjustments. However, there is insufficient evidence to recommend specific dose changes. Generally, continue same dose if benefit outweighs risk, but consider discontinuing in the third trimester to minimize fetal exposure, with dose adjustments as needed postpartum.
Acarbose delays carbohydrate absorption by inhibiting alpha-glucosidase in the brush border of the small intestine. It should be taken with the first bite of each main meal. Its efficacy is limited by gastrointestinal side effects (flatulence, diarrhea) due to undigested carbohydrates reaching the colon. Not recommended in patients with inflammatory bowel disease or colonic obstruction. Hypoglycemia from acarbose (rare in monotherapy) must be treated with oral glucose or milk, not sucrose or complex carbohydrates, since their digestion is blocked. Acarbose can cause isolated transaminase elevations; monitor LFTs if symptoms occur.
CYLTEZO (adalimumab-adbm) is a TNF-alpha inhibitor biosimilar to Humira. Subcutaneous injection sites should be rotated; do not inject into tender, bruised, or scarred skin. Live vaccines are contraindicated during therapy. Screen for latent TB and hepatitis B prior to initiation. Monitor for signs of infection, especially in elderly patients. Consider temporary discontinuation if serious infection occurs. May increase risk of lymphoma and other malignancies. Not recommended in patients with moderate to severe heart failure.
Take acarbose with the first bite of each main meal; do not take it between meals.,Common side effects include gas, bloating, and diarrhea, which may improve over time.,If you experience low blood sugar, treat it with glucose tablets, juice, or regular soda, not candy or fruit juice (acarbose blocks their digestion).,Tell your doctor if you develop jaundice or abdominal pain, as liver problems can occur.,This medication is not for weight loss and does not affect insulin secretion.
Cyltezo is a biosimilar of Humira and works by reducing inflammation.,Inject the medication subcutaneously as directed; rotate injection sites.,Do not receive live vaccines (e.g., MMR, chickenpox, nasal flu) while on Cyltezo.,Contact your doctor immediately if you have signs of infection (fever, cough, painful urination).,Seek medical attention for symptoms of allergic reaction (hives, difficulty breathing, swelling).,Inform your doctor if you have a history of TB, hepatitis B, heart failure, or cancer.,Store Cyltezo in the refrigerator; do not freeze. Protect from light.
"Acarbose, an alpha-glucosidase inhibitor, delays carbohydrate absorption in the gut, leading to a reduction in postprandial hyperglycemia. Levomilnacipran, a serotonin-norepinephrine reuptake inhibitor (SNRI), may enhance insulin sensitivity in some patients, potentially increasing the risk of hypoglycemia when combined with acarbose. The interaction is primarily due to additive effects on glucose metabolism, and patients should be monitored for signs of hypoglycemia, particularly during initiation or dose adjustments."
"Chlorothiazide, a thiazide diuretic, can decrease the therapeutic efficacy of acarbose, an alpha-glucosidase inhibitor used for postprandial glycemic control in type 2 diabetes. The hypokalemia induced by chlorothiazide may impair insulin secretion and reduce the glucose-lowering effect of acarbose, potentially leading to elevated postprandial glucose levels. This interaction may necessitate dose adjustments or alternative antihyperglycemic therapy to maintain glycemic control."
"Acarbose, an alpha-glucosidase inhibitor, delays carbohydrate digestion and absorption, thereby reducing postprandial hyperglycemia. Selegiline, a selective MAO-B inhibitor at therapeutic doses, can potentiate the hypoglycemic effect of acarbose by an unknown pharmacodynamic mechanism, potentially leading to episodes of hypoglycemia. This interaction is of particular concern in patients with diabetes mellitus who are co-prescribed these agents, as the combined effect on glucose homeostasis may require dose adjustments or enhanced monitoring."
