Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action JENTADUETO XR JENTADUETO XR contains: linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, and metformin, a biguanide. Linagliptin Linagliptin is an inhibitor of DPP-4, an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Thus, linagliptin increases the concentrations of active incretin hormones, stimulating the release of insulin in a glucose-dependent manner and decreasing the levels of glucagon in the circulation. Both incretin hormones are involved in the physiological regulation of glucose homeostasis. Incretin hormones are secreted at a low basal level throughout the day and levels rise immediately after meal intake.

Dosage

2 DOSAGE AND ADMINISTRATION Individualize the starting dosage of JENTADUETO XR based on the patient's current regimen ( 2.1 ) The maximum recommended dosage is 5 mg linagliptin/2,000 mg metformin HCl once daily ( 2.1 ) Take orally once daily with a meal, with gradual dose escalation to reduce the gastrointestinal effects due to metformin ( 2.1 ) Swallow whole; do not split, crush, dissolve, or chew ( 2.1 ) Prior to initiation, assess renal function with estimated glomerular filtration rate (eGFR) ( 2.2 ) Do not use in patients with eGFR below 30 mL/min/1.

Black Box Warning

WARNING: LACTIC ACIDOSIS Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The 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 was 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...

Interactions

  • 7 DRUG INTERACTIONS Table 2 describes clinically relevant interactions with JENTADUETO XR. Table 2 Clinically Relevant Interactions with JENTADUETO XR Carbonic Anhydrase Inhibitors Clinical Impact Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide) frequently cause a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with JENTADUETO XR may increase the risk of lactic acidosis. Intervention Consider more frequent monitoring of these patients.
