Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Alogliptin is a selective, reversible inhibitor of dipeptidyl peptidase-4 (DPP-4). By inhibiting DPP-4, it increases the levels of active incretin hormones (GLP-1 and GIP), which stimulate insulin secretion in a glucose-dependent manner and suppress glucagon release, thereby improving glycemic control.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Adjunct to diet and exercise to improve glycemic control in type 2 diabetes mellitus,Combination therapy with metformin, sulfonylurea, thiazolidinedione, or insulin
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
25 mg orally once daily
Initial: 5 mg orally once or twice daily; increase by 5 mg increments weekly; usual maintenance: 20-30 mg daily in divided doses; maximum: 40 mg/day
Terminal elimination half-life is approximately 12-21 hours. This supports once-daily dosing. In patients with renal impairment, half-life is prolonged (e.g., up to 32 hours in severe impairment), necessitating dose adjustment.
Terminal elimination half-life: d-amphetamine 10-13 hours, l-amphetamine 13-15 hours; in adults (children: 6-8 hours). The longer half-life allows for once-daily dosing.
Alogliptin is minimally metabolized; approximately 60-70% excreted unchanged in urine. Metabolism involves hepatic microsomal enzymes, primarily CYP2D6 and CYP3A4, but to a minor extent.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Approximately 60-71% of the dose is excreted unchanged in urine via active renal tubular secretion, with about 20% eliminated as metabolites (primarily N-demethylated and N-acetylated derivatives) in urine, and less than 2% in feces. Renal excretion is the major route.
Approximately 30-40% of a dose is excreted unchanged in urine; the remainder is metabolized primarily by oxidative deamination and aromatic hydroxylation. Biliary/fecal elimination accounts for less than 5%.
20% bound to plasma proteins, primarily albumin. Binding is concentration-independent.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Volume of distribution is approximately 33 L (0.47 L/kg assuming 70 kg). This suggests distribution into total body water, but not extensive tissue binding.
Vd: 3-4 L/kg (approximately 210-280 L for a 70 kg adult). This indicates extensive tissue distribution and penetration into the central nervous system.
Oral bioavailability is approximately 100%, indicating complete absorption with minimal first-pass metabolism.
Oral immediate-release: approximately 75-100%; oral extended-release: approximately 94% relative to immediate-release. Food does not significantly affect absorption but may delay peak concentration.
e GFR 30-59 m L/min: 12.5 mg orally once daily; e GFR 15-29 m L/min: 6.25 mg orally once daily; e GFR <15 m L/min or dialysis: 6.25 mg orally once daily
GFR 30-89 m L/min: no adjustment; GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: avoid use
No dose adjustment required for mild to moderate hepatic impairment (Child-Pugh A and B); not recommended for severe hepatic impairment (Child-Pugh C)
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Safety and efficacy not established; no recommended dosing available

No specific food interactions; can be taken with or without food. Avoid excessive alcohol intake due to potential hypoglycemia risk when used with other agents.
Avoid high-fat meals as they delay absorption; avoid acidic foods (e.g., citrus) and vitamin C supplements within 1 hour of dosing as they decrease absorption; limit caffeine and other stimulants to avoid additive cardiovascular effects.
Alogliptin is classified as FDA Pregnancy Category B. Animal studies showed no teratogenic effects at exposures up to 100 times the human clinical dose. However, no adequate and well-controlled studies in pregnant women exist. Use only if clearly needed. First trimester risk cannot be ruled out; limited human data.
Pregnancy category C. First trimester: No well-controlled studies, but potential for congenital malformations not definitively established. Second and third trimesters: Increased risk of premature delivery, low birth weight, and neonatal withdrawal symptoms (e.g., dysphoria, agitation, lassitude). Chronic use may lead to neonatal toxicity.
It is unknown if alogliptin is excreted in human breast milk. No M/P ratio available. Due to potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account importance to the mother.
Excreted in breast milk. M/P ratio unknown. Potential for stimulant effects in infant (e.g., irritability, poor feeding, insomnia). Caution advised; consider alternative feeding methods.
No specific dose adjustments recommended; however, pregnancy may alter pharmacokinetics of alogliptin. Avoid use when possible, particularly during the second and third trimesters, due to limited safety data.
No established dosing guidelines. Due to increased plasma volume and clearance, dose may need titration to clinical effect, but avoid supratherapeutic doses. Use lowest effective dose.
Alogliptin is a DPP-4 inhibitor with minimal risk of hypoglycemia when used as monotherapy; dosing adjustments required for renal impairment (creatinine clearance <60 m L/min). Monitor for acute pancreatitis and severe arthralgia. No significant weight loss or gain. Use with caution in patients with history of pancreatitis.
For ADHD: start low, go slow; monitor weight and height in children; avoid late doses to prevent insomnia; check for abuse/diversion; screen for bipolar disorder and hypertension; consider urine drug screen before prescribing; avoid MAOIs within 14 days; use with caution in seizure disorders and glaucoma.

"The coadministration of alogliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, with chloroquine may lead to increased plasma concentrations of chloroquine. This occurs because alogliptin potentially inhibits CYP2C8 and/or CYP3A4, the cytochrome P450 enzymes responsible for chloroquine metabolism. As a result, patients may be at higher risk for chloroquine-related adverse effects such as cardiac arrhythmias (QT prolongation), retinopathy, and hypoglycemia."
"Sunitinib, a tyrosine kinase inhibitor, may enhance the glucose-lowering effects of alogliptin, a DPP-4 inhibitor, by impairing renal function and potentially reducing the renal clearance of alogliptin, leading to increased exposure and risk of hypoglycemia. This interaction is particularly relevant in patients with pre-existing renal impairment or those receiving high-dose sunitinib. Clinical outcomes include episodes of symptomatic hypoglycemia, which may require dose adjustment of antidiabetic therapy."
"Alogliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, increases endogenous incretin levels, enhancing glucose-dependent insulin secretion. Mesalazine, known for its anti-inflammatory effects in inflammatory bowel disease, may independently lower blood glucose via unknown mechanisms. Concurrent use could potentiate hypoglycemic effects, especially in patients with diabetes or impaired glucose regulation, increasing the risk of symptomatic hypoglycemia."
