Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Empagliflozin is a sodium-glucose co-transporter 2 (SGLT2) inhibitor that reduces renal glucose reabsorption, increasing urinary glucose excretion. Linagliptin is a dipeptidyl peptidase 4 (DPP-4) inhibitor that prolongs the activity of incretin hormones (GLP-1, GIP), enhancing glucose-dependent insulin secretion and suppressing glucagon release.
Estrogen replacement therapy; binds to estrogen receptors, activating gene transcription and promoting development and maintenance of female reproductive tissues and secondary sex characteristics.

10 mg empagliflozin/5 mg linagliptin orally once daily.
1 tablet (2.5 mg estradiol and 0.625 mg norgestimate) orally once daily
Empagliflozin: ~12.4 h (supports once-daily dosing). Linagliptin: ~12 h (terminal half-life; long binding to DPP-4 allows once-daily dosing despite short half-life).
Terminal elimination half-life is 13-18 hours; steady-state achieved after 5-7 days.
Empagliflozin is primarily metabolized via glucuronidation (UGT2B7, UGT1A3, UGT1A8, UGT1A9) with minor CYP450 involvement. Linagliptin is minimally metabolized; approximately 90% is excreted unchanged via enterohepatic system (biliary excretion) and renal elimination is negligible.
Hepatic metabolism via cytochrome P450 enzymes (CYP3A4 and others); undergoes enterohepatic recirculation.
Empagliflozin: ~54% renal (unchanged), ~41% fecal (primarily unchanged parent). Linagliptin: ~80% fecal (enterohepatic circulation), ~5% renal.
Primarily renal (90-95%) as glucuronide and sulfate conjugates; biliary/fecal elimination accounts for <5%.
Empagliflozin: ~86.2% (primarily albumin). Linagliptin: 70-80% (concentration-dependent, saturable binding to DPP-4; also albumin).
98% bound primarily to albumin and sex hormone-binding globulin (SHBG).
Empagliflozin: Vd/F ~9.6 L (0.14 L/kg; extensive tissue distribution). Linagliptin: Vd ~1000 L (14 L/kg; large due to extensive tissue binding).
1.0-1.5 L/kg; indicates extensive tissue distribution and binding.
Empagliflozin: oral bioavailability ~78% (high, unaffected by food). Linagliptin: oral bioavailability ~30% (food has no effect; low due to first-pass and saturable absorption).
Oral: 2-10% due to first-pass metabolism; IM: 100%; Transdermal: 5-15%; Vaginal: 5-25%.
Contraindicated if e GFR < 30 m L/min/1.73 m². Not recommended if e GFR < 45 m L/min/1.73 m². No dose adjustment for e GFR ≥ 45 m L/min/1.73 m².
No specific dose adjustment required; use with caution in severe impairment (e GFR <30 m L/min/1.73m²) due to potential fluid retention
No dose adjustment required for mild, moderate, or severe hepatic impairment (Child-Pugh A, B, C).
Contraindicated in Child-Pugh class B and C; for class A, use lowest effective dose with monitoring
Safety and efficacy not established in pediatric patients.
Not indicated for pediatric use; safety and efficacy not established
No dose adjustment based on age alone. Assess renal function; contraindicated if e GFR < 30 m L/min/1.73 m². Consider increased risk of volume depletion and hypotension in patients aged ≥75 years.
Use lowest effective dose for shortest duration; increased risk of stroke, dementia, and breast cancer; consider alternative therapies
None

No significant food interactions. Alcohol may increase risk of lactic acidosis and ketoacidosis; limit intake. Avoid grapefruit juice as it may affect linagliptin metabolism (minor interaction, but caution advised).
Grapefruit and grapefruit juice may increase estrogen levels; avoid large amounts. No significant food interactions reported but take with or without food consistently to maintain stable absorption.
Empagliflozin: Based on animal studies, empagliflozin may cause renal toxicity in the developing fetus, particularly during the second and third trimesters when fetal kidneys are maturing. Human data are limited; however, SGLT2 inhibitors are generally avoided in the second and third trimesters due to potential risk of acute kidney injury in neonates. Linagliptin: Animal studies have shown no evidence of teratogenicity at clinically relevant doses. Human data are insufficient; however, DPP-4 inhibitors are generally considered low risk during pregnancy. Overall, combination should be avoided unless clearly needed, particularly in the second and third trimesters.
First trimester: Increased risk of congenital anomalies including cardiovascular defects and neural tube defects. Second and third trimesters: Risk of urogenital tract abnormalities, feminization of male fetus, and potential long-term reproductive effects. Use contraindicated in pregnancy.
Empagliflozin: Unknown if excreted in human milk; animal studies show excretion in milk. Due to potential for adverse effects on the developing infant (e.g., renal effects), breastfeeding is not recommended. Linagliptin: Unknown if excreted in human milk; animal studies show low levels in milk. Caution is advised. Both drugs: M/P ratio not available. Manufacturer recommends discontinuing drug or breastfeeding.
Contraindicated during breastfeeding. Amnestrogen is excreted in breast milk; M/P ratio unknown. Potential for serious adverse effects in nursing infants including hormonal disruption.
Empagliflozin: Pregnancy alters pharmacokinetics (increased renal clearance, volume of distribution), but no specific dose adjustments are recommended due to lack of data. However, empagliflozin is contraindicated in pregnancy, particularly in the second and third trimesters. Linagliptin: No dose adjustment required based on pharmacokinetic changes in pregnancy; however, safety data are limited. Overall, alternative therapies are preferred during pregnancy.
Not applicable as drug is contraindicated in pregnancy. No dose adjustment recommended due to avoidance of use.
Empagliflozin/linagliptin should not be used in patients with type 1 diabetes or for diabetic ketoacidosis treatment. Assess renal function before initiation and periodically; e GFR <45 m L/min/1.73 m2 is a contraindication for empagliflozin. Monitor for signs of ketoacidosis, even if blood glucose is not markedly elevated. Linagliptin does not require dose adjustment for renal impairment. Genital mycotic infections and urinary tract infections are common with empagliflozin; counsel on hygiene. Temporary discontinuation of SGLT2 inhibitors is recommended before surgery or during prolonged fasting to reduce ketoacidosis risk.
Amnestrogen (estrogen-progestin combination) is used for hormone replacement therapy. Monitor for thromboembolic events; avoid in patients with history of DVT/PE. Use lowest effective dose for shortest duration. Not for use in pregnancy; contraindicated in breast cancer. May increase risk of endometrial cancer if used without progestin in women with intact uterus.

"Empagliflozin, a sodium-glucose cotransporter-2 inhibitor, reduces renal glucose reabsorption, leading to decreased blood glucose levels. Rosoxacin, a quinolone antibiotic, may enhance the hypoglycemic effects of empagliflozin by potentiating insulin secretion or improving insulin sensitivity, which could increase the risk of hypoglycemic episodes, especially in patients with diabetes mellitus."
"Quinethazone, a thiazide-like diuretic, reduces intravascular volume and may blunt the osmotic diuretic effect of empagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, thereby decreasing empagliflozin's efficacy in lowering blood glucose. This interaction is mediated through volume contraction leading to reduced renal perfusion and diminished glucose excretion. Clinically, patients may experience higher-than-expected blood glucose levels, potentially compromising glycemic control."
"Concomitant use of lisinopril, an angiotensin-converting enzyme inhibitor, and empagliflozin, a sodium-glucose cotransporter-2 inhibitor, may enhance the risk of hypotension, acute kidney injury, and hyperkalemia. Lisinopril reduces angiotensin II-mediated vasoconstriction and aldosterone secretion, which can be compounded by empagliflozin-induced volume depletion and osmotic diuresis. This interaction is particularly concerning in patients with renal impairment or those on other medications affecting the renin-angiotensin-aldosterone system."
