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

1 tablet (2.5 mg estradiol and 0.625 mg norgestimate) orally once daily
10 mg empagliflozin / 5 mg linagliptin orally once daily
Terminal elimination half-life is 13-18 hours; steady-state achieved after 5-7 days.
Empagliflozin: terminal half-life ~12.4 hours, allowing once-daily dosing. Linagliptin: terminal half-life ~113-131 hours due to saturable binding to DPP-4, enabling once-daily dosing despite short plasma half-life.
Hepatic metabolism via cytochrome P450 enzymes (CYP3A4 and others); undergoes enterohepatic recirculation.
Empagliflozin: primarily glucuronidation by UGT2B7, UGT1A3, UGT1A8, and UGT1A9. Linagliptin: primarily enterohepatic recirculation with minimal hepatic metabolism; metabolized by CYP3A4 to a minor extent.
Primarily renal (90-95%) as glucuronide and sulfate conjugates; biliary/fecal elimination accounts for <5%.
Empagliflozin: 54% excreted unchanged in urine (renal), 41% in feces (biliary/fecal). Linagliptin: 80% excreted unchanged in feces via enterohepatic circulation, <5% in urine.
98% bound primarily to albumin and sex hormone-binding globulin (SHBG).
Empagliflozin: 86.2% bound primarily to plasma proteins (albumin). Linagliptin: 70-89% bound; concentration-dependent, mainly to albumin.
1.0-1.5 L/kg; indicates extensive tissue distribution and binding.
Empagliflozin: Vd ~38 L (0.5-0.6 L/kg), reflecting moderate tissue distribution. Linagliptin: Vd ~1,040 L (15 L/kg), indicating extensive tissue binding (e.g., DPP-4 enzyme).
Oral: 2-10% due to first-pass metabolism; IM: 100%; Transdermal: 5-15%; Vaginal: 5-25%.
Empagliflozin: oral bioavailability ~78% in therapeutic range, decreased with high-fat meal; no dose adjustment. Linagliptin: oral bioavailability ~30% due to presystemic metabolism; food decreases Cmax but not AUC.
No specific dose adjustment required; use with caution in severe impairment (e GFR <30 m L/min/1.73m²) due to potential fluid retention
e GFR ≥45 m L/min/1.73m2: no adjustment. e GFR 30-44: contraindicated (empagliflozin labeled for use, but renal efficacy not established; linagliptin no adjustment). e GFR <30: contraindicated (empagliflozin); linagliptin no adjustment but caution. Empagliflozin not recommended if on dialysis.
Contraindicated in Child-Pugh class B and C; for class A, use lowest effective dose with monitoring
Child-Pugh A, B, C: no adjustment required for empagliflozin or linagliptin. However, experience in severe hepatic impairment is limited.
Not indicated for pediatric use; safety and efficacy not established
Safety and efficacy not established in pediatric patients under 18 years.

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.
No significant food interactions. Acutely reduce alcohol consumption due to possible increased risk of ketoacidosis.
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: Limited human data; animal studies show renal toxicity in developing kidneys. Risk cannot be excluded. Linagliptin: No evidence of teratogenicity in animal studies; limited human data. Both drugs are not recommended during pregnancy, especially in the second and third trimesters due to potential fetal renal effects.
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: Unknown if excreted in human milk; risk to infant not excluded. Linagliptin: Excreted in rat milk; unknown in humans. M/P ratio not available. Breastfeeding is not recommended during therapy.
Not applicable as drug is contraindicated in pregnancy. No dose adjustment recommended due to avoidance of use.
No established dose changes for pregnancy; pharmacokinetic changes in pregnancy (increased renal clearance, volume of distribution) may alter drug exposure, but insufficient data to recommend adjustments. Therapy should be discontinued during pregnancy due to potential risks.
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/linagliptin is a fixed-dose combination for type 2 diabetes. Assess renal function before initiation; empagliflozin is not recommended if e GFR <30 m L/min/1.73 m².

No interactions on record
"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."
