Warnings
Black Box Warnings
Lactic acidosis
- Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias
- Lactic acidosis can occur due to metformin accumulation
- Risk increases with conditions such as renal impairment, sepsis, dehydration, excess alcohol intake, hepatic impairment, and acute CHF
- Onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain
- Metformin-associated lactic acidosis has been characterized by elevated blood lactate levels (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL
- Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (eg, acute congestive heart failure), excessive alcohol intake, and hepatic impairment
- If metformin-associated lactic acidosis suspected, immediately discontinue therapy and institute general supportive measures in a hospital setting; prompt hemodialysis is recommended
Contraindications
Renal impairment (eg, eGFR <30 ml/min/1.73 m²) which may also result from conditions such as cardiovascular collapse (shock), acute myocardial infarction, and septicemia
Acute or chronic metabolic acidosis, including diabetic ketoacidosis
History of hypersensitivity reaction to linagliptin (eg, urticaria, angioedema, bronchial hyperreactivity) or metformin
Cautions
Diabetic ketoacidosis should be treated with insulin
Monitor hepatic and renal function; risk of metformin accumulation and lactic acidosis increases with renal impairment; hepatic impairment limits ability to clear lactate
Avoid excessive alcohol intake; alcohol is known to potentiate effect of metformin on lactate metabolism
Use of concomitant medications that may affect renal function or metformin disposition
Use in combination with an insulin secretagogue (eg, sulfonylurea) was associated with a higher rate of hypoglycemia compared with placebo in a clinical trial; therefore, a lower dose of insulin secretagogue or insulin may be required to reduce risk of hypoglycemia when used in combination with this drug
Cardiovascular collapse (shock) from whatever cause (eg, acute congestive heart failure, acute myocardial infarction, and other conditions characterized by hypoxemia) has been associated with lactic acidosis and may also cause prerenal azotemia; discontinue drug promptly
Severe and disabling arthralgia reported in patients taking DPP-4 inhibitors; consider as a possible cause for severe joint pain and discontinue drug if appropriate
No conclusive evidence of macrovascular risk reduction reported with antidiabetic drugs
Serious hypersensitivity reactions reported including anaphylaxis, angioedema, and exfoliative skin conditions; discontinue therapy promptly, assess for other potential causes, institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes
Heart failure has been observed with two other members of the DPP-4 inhibitor class; consider risks and benefits of empagliflozin in patients with risk factors for heart failure; monitor for signs and symptoms; if heart failure develops, manage accordingly to standard of care and consider interrupting treatment; advise patients of the characteristic symptoms of heart failure and to immediately report such symptoms
Bullous pemphigoid reported with DPP-4 inhibitor use, which required hospitalization; in reported cases, patients recovered with topical or systemic immunosuppressive treatment and discontinuation of DPP-4 inhibitor; patients should report development blisters/erosions; discontinue DPP-4 therapy and consult a dermatologist if bullous pemphigoid suspected
Vitamin B12 deficiency
- May lead to decreased levels of vitamin B12 without clinical manifestations (occurred in approximately 7% of patients)
- Certain individuals (those with inadequate vitamin B12 or calcium intake or absorption) appear to be predisposed to developing subnormal vitamin B12 levels
- Measure hematologic parameters on an annual basis and vitamin B12 at 2 to 3-year intervals in patients on this drug and manage any abnormalities
Iodinated contrast imaging procedures
- Discontinue metformin at the time of or before an iodinated contrast imaging procedure in patients with an eGFR between 30-60 mL/minute/1.73 m²; in patients with a history of liver disease, alcoholism, or heart failure; or in patients who will be administered intra-arterial iodinate contrast
- Reevaluate eGFR 48 hr after the imaging procedure; restart metformin if renal function is stable
Pancreatitis
- Postmarketing reports of acute pancreatitis, including fatal pancreatitis; monitor for signs and symptoms of pancreatitis, and discontinue if suspected
- Unknown if patients with history of pancreatitis are at increased risk for the development of pancreatitis while using linagliptin
Lactic acidosis
- Metformin decreases liver uptake of lactate increasing lactate blood levels which may increase risk of lactic acidosis, especially in patients at risk
- If metformin-associated lactic acidosis is suspected, general supportive measures should be instituted promptly in a hospital setting, along with immediate discontinuation of therapy
- In treated patients with a diagnosis or strong suspicion of lactic acidosis, prompt hemodialysis is recommended to correct acidosis and remove accumulated metformin (metformin is dialyzable, with clearance of up to 170 mL/min under good hemodynamic conditions); hemodialysis has often resulted in reversal of symptoms and recovery
- Educate patients and their families about the symptoms of lactic acidosis and if these symptoms occur instruct them to discontinue therapy and report these symptoms to their healthcare provider
- Withholding of food and fluids during surgical or other procedures may increase risk for volume depletion, hypotension and renal impairment; therapy should be temporarily discontinued while patients have restricted food and fluid intake
- Several of the postmarketing cases of metformin-associated lactic acidosis occurred in the setting of acute congestive heart failure (particularly when accompanied by hypoperfusion and hypoxemia); cardiovascular collapse (shock), acute myocardial infarction, sepsis, and other conditions associated with hypoxemia have been associated with lactic acidosis and may also cause prerenal azotemia; when such events occur, discontinue therapy
- Alcohol potentiates effect of metformin on lactate metabolism and this may increase risk of metformin-associated lactic acidosis; warn patients against excessive alcohol intake while receiving this drug
- Patients with hepatic impairment have developed cases of metformin-associated lactic acidosis; this may be due to impaired lactate clearance resulting in higher lactate blood levels; therefore, avoid use of this drug in patients with clinical or laboratory evidence of hepatic disease
- The postmarketing metformin-associated lactic acidosis cases primarily occurred in patients with significant renal impairment
- Risk of metformin accumulation and metformin-associated lactic acidosis increases with the severity of renal impairment because metformin is substantially excreted by the kidney
-
Clinical recommendations for renal impairment
- Before initiating therapy, obtain an estimated glomerular filtration rate (eGFR)
- Therapy is contraindicated in patients with an eGFR < 30 mL/min/1.73 m2
- Initiation of therapy is not recommended in patients with eGFR between 30 – 45 mL/min/1.73 m2
- Obtain an eGFR at least annually in all patients receiving therapy; in patients at increased risk for development of renal impairment (eg, the elderly), renal function should be assessed more frequently
- In patients receiving therapy whose eGFR later falls <45 mL/min/1.73 m2 assess benefit and risk of continuing therapy
Drug interaction overview
- Concomitant use of this drug with specific drugs may increase risk of metformin-associated lactic acidosis, including drugs that impair renal function, result in significant hemodynamic change, interfere with acid-base balance or increase metformin accumulation; therefore, consider more frequent monitoring of patients
- Administration of intravascular iodinated contrast agents in metformin-treated patients has led to an acute decrease in renal function and occurrence of lactic acidosis; stop this drug at time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR between 30 and60 mL/min/1.73 m2; in patients with a history of hepatic impairment, alcoholism, or heart failure; or in patients who will be administered intra-arterial iodinated contrast; re-evaluate eGFR 48 hours after imaging procedure, and restart therapy if renal function is stable
Pregnancy & Lactation
Pregnancy
Limited data in pregnant women not sufficient to inform associated risk for major birth defects and miscarriage with product; published studies with metformin use during pregnancy have not reported a clear association with metformin and major birth defect or miscarriage risk; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy
Poorly controlled diabetes in pregnancy increases maternal risk for diabetic ketoacidosis, pre-eclampsia, and delivery complications; poorly controlled diabetes increases fetal risk for major birth defects, still birth, and macrosomia-related morbidity
Animal data
- No adverse functional, behavioral, or reproductive outcome was observed in offspring following administration of linagliptin to Wistar Han rats from gestation day 6 to lactation day 21 at a dose 49-times the 5 mg clinical dose, based on exposure
- Linagliptin crosses the placenta into the fetus following oral dosing in pregnant rats and rabbits
- Metformin hydrochloride did not cause adverse developmental effects when administered to pregnant Sprague Dawley rats and rabbits at up to 600 mg/kg/day during period of organogenesis; this represents an exposure of approximately 2-and 6-times a clinical dose of 2000 mg, based on body surface area (mg/m2) for rats and rabbits, respectively
Lactation
There is no information regarding presence of product in human milk, effects on breastfed infant, or effects on milk production; however, linagliptin is present in rat milk; limited studies report that metformin is present in human milk; there is insufficient information to determine effects of metformin on breastfed infant and no available information on effects of metformin on milk production; therefore, developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Linagliptin: Dipeptidyl peptidase 4 (DPP-4) inhibitor; increases and prolongs incretin hormone activity from glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) which are inactivated by the DPP-4 enzyme; incretins increase insulin release and reduce glucagon secretion
Metformin: Decreases hepatic glucose production; decreases GI intestinal glucose absorption; increases target cell insulin sensitivity; lowers both basal and postprandial plasma glucose and unlike sulfonylureas, does not typically produce hypoglycemia or hyperinsulinemia
Absorption
Bioavailability: 30% (linagliptin); 50-60% (metformin)
Distribution
Protein Bound: 70-80% (linagliptin); >90% (metformin)
Vd: ~1,110 L (linagliptin); ~654 L (metformin)
Metabolism
Linagliptin
- Metabolites: Has pharmacologically inactive metabolite, which shows a steady-state exposure of 13.3% relative to linagliptin
- CYP3A4 substrate
- Weak-to-moderate CYP3A4 inhibitor
- P-gp substrate; inhibits P-gp transport at high concentrations
Metformin
- Metformin is excreted 100% in the urine therefore does not undergo metabolism in the body the following information is for linagliptin
Elimination
Half-life: 12 hr (linagliptin); 6.2 hr (metformin)
Dialyzable: Removal of linagliptin by dialysis is unlikely and metformin is dialyzable (clearance of up to 170 mL/min under good hemodynamic conditions)
Renal clearance: 70 mL/min (linagliptin)
Excretion: Linagliptin enterohepatic system (80%) or urine (5%); metformin urine (90%)
Administration
Oral Administration
Take with a meal
Dosing should be individualized on the basis of both effectiveness and tolerability, while not exceeding the maximum recommended dose for either prompt-release or extended-release tablets
Prompt-release: When initiating, dose escalation should be gradual to reduce the GI side effects associated with metformin
Extended-release
- Swallow tablet whole; do not split, crush, dissolve, or chew before swallowing
- Extended-release tablet should be taken as a single tablet once daily; if dose is 5 mg/2000 mg, use 2.5 mg linagliptin/1000 mg metformin extended-release tablets and take two tablets together once daily
