Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dapagliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor that blocks glucose reabsorption in the proximal renal tubule, reducing plasma glucose independent of insulin secretion. Saxagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that prolongs incretin hormone activity, increasing insulin release and decreasing glucagon secretion.
Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
Adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Oral: 1 tablet (dapagliflozin 5 mg / saxagliptin 5 mg) once daily, taken with or without food, in combination with metformin or other glucose-lowering agents.
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.
Dapagliflozin: Terminal half-life ~12.9 hours (supports once-daily dosing). Saxagliptin: Terminal half-life ~2.5 hours, but active metabolite 5-hydroxy saxagliptin has half-life ~3.1 hours (supports once-daily dosing due to prolonged DPP-4 inhibition).
Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
Dapagliflozin is primarily metabolized via glucuronidation by UGT1A9; saxagliptin is metabolized via CYP3A4/5 to an active metabolite.
Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.
Dapagliflozin: ~75% renal excretion (21% unchanged, 50% as major metabolite 3-O-glucuronide), ~21% fecal. Saxagliptin: ~75% renal excretion (12% unchanged, 22% as major metabolite 5-hydroxy saxagliptin, 41% as other metabolites), ~22% fecal.
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.
Dapagliflozin: ~91% bound primarily to albumin. Saxagliptin: Negligible (<10% bound).
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
Dapagliflozin: Vd ~118 L (1.5 L/kg based on 70 kg, indicating extensive extravascular distribution). Saxagliptin: Vd ~71 L (1.0 L/kg based on 70 kg, indicating distribution into tissues).
Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.
Dapagliflozin: Oral bioavailability ~78% (high, influenced by food). Saxagliptin: Oral bioavailability ~75% (high, not significantly affected by food).
Oral immediate-release: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.

Dapagliflozin is contraindicated in the second and third trimesters due to risk of fetal renal toxicity. Saxagliptin has limited human data; animal studies show no major malformations but potential for delayed ossification at high doses. First trimester: Use only if clearly needed; no well-controlled human studies. Second and third trimesters: Dapagliflozin not recommended; avoid.
Pregnancy Category C. First trimester: potential increased risk of congenital malformations (e.g., gastroschisis, oral clefts) based on limited human data. Second and third trimesters: risk of fetal growth restriction, preterm delivery, and neonatal withdrawal symptoms (irritability, poor feeding).
No data on excretion in human milk. Dapagliflozin is present in rat milk; saxagliptin is excreted in rat milk. M/P ratio unknown. Caution advised due to potential for adverse effects in nursing infant.
Excreted into breast milk; relative infant dose estimated at 2-4% of maternal weight-adjusted dose. M/P ratio not well established. Manufacturer recommends caution; potential for infant agitation, insomnia, and growth suppression.
No specific dose adjustments established for pregnancy. Dapagliflozin is not recommended in pregnancy; consider alternative therapy. Saxagliptin: dose adjustment not required based on pharmacokinetic changes; however, lack of data limits recommendation.
Increased plasma volume and enhanced hepatic metabolism may reduce amphetamine levels; dose adjustments should be individualized based on clinical response, but controlled studies lacking. Avoid abrupt discontinuation due to risk of withdrawal symptoms in mother and neonate.
Monitor renal function before initiation and periodically; contraindicated if e GFR <45 m L/min/1.73 m². Assess volume status due to diuretic effect. Watch for pancreatitis and hypersensitivity. Adjust insulin or sulfonylurea doses to reduce hypoglycemia risk. Discontinue if pancreatitis suspected. T1DM is not an indication.

"Saxagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, enhances incretin levels leading to glucose-dependent insulin secretion, while Milnacipran, a serotonin-norepinephrine reuptake inhibitor (SNRI), may independently affect glucose homeostasis. Concurrent use could theoretically increase the risk of hypoglycemia due to additive effects on insulin secretion or glucose metabolism, although clinical data are limited. Patients should be monitored for signs of hypoglycemia, especially if also on other glucose-lowering agents."
"Tolazamide, a sulfonylurea, increases insulin secretion from pancreatic beta cells, while saxagliptin, a DPP-4 inhibitor, prolongs the action of incretin hormones (GLP-1 and GIP) to enhance glucose-dependent insulin release. When coadministered, the complementary mechanisms can lead to additive hypoglycemic effects, significantly increasing the risk of hypoglycemia, particularly in patients with renal impairment or those on irregular meal schedules."
"Saxagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, has been reported to potentially reduce the systemic exposure of theophylline, a xanthine bronchodilator, likely through the induction of cytochrome P450 (CYP) 1A2, the primary enzyme responsible for theophylline metabolism. This interaction may lead to subtherapeutic theophylline concentrations, resulting in decreased bronchodilator efficacy and potential exacerbation of respiratory symptoms, particularly in patients with asthma or chronic obstructive pulmonary disease. The effect appears to be modest but may be clinically relevant in patients requiring stable theophylline levels."
