II. Indications
- Type II Diabetes Mellitus
-
Insulin deficiency and Insulin Resistance
- Adjunct to Glucophage, Sulfonylureas, Glitazones
III. Mechanism
- Dipeptidyl Peptidase-4 (DPP-4) is an enzyme that degrades the Incretins GLP-1 and GLP-2
- DPP4 Inhibitor Activity
- DPP-4 Inhibitors block Incretin degradation
- Allows accumulation of GLP-1 by 2-3 fold
- Activate Glucose-Dependent Insulinotropic Polypeptides
- Stimulates beta cells to secrete Insulin
- Lowers Blood Sugar, but low risk of Hypoglycemia
- DPP-4 Inhibitors block Incretin degradation
- Differs from GLP1 Agonists
- Weight neutral
- No Nausea
IV. Precautions
- Gliptins are less than half as effective as lower cost medications (e.g. Metformin, Sulfonylureas)
- No longterm evidence of improved outcomes
- Expensive (>$400/month)
- Decrease dose in renal Impairment
- May consider for those close to goal AND
- Already either on other Oral Hypoglycemics or in whom they are contraindicated (e.g. Chronic Kidney Disease)
V. Contraindications
- Type I Diabetes Mellitus
- Prior history of malignancy
- Due to increased risk of cancer invasion and metastases
- Women of child bearing age (relative contraindication)
- Teratogenicity risk
- Congestive Heart Failure
VI. Adverse Effects
-
Acute Pancreatitis
- Incidence may be as high as 1 in 50 for two years
- Singh (2013) JAMA Intern Med 173(7):534-9 [PubMed]
- Serious Allergic Reaction (Sitagliptin)
- Hepatotoxicity (Alogliptin, Vlidagliptin)
- Headache
- Bullous Pemphigoid
-
Congestive Heart Failure exacerbation
- Risk of hospitalized CHF exacerbation: 1 in 150 patients/2 years using Saxigliptin or Alogliptin
- Sitagliptin (Januvia) is less associated with CHF exacerbation
- Scirica (2013) N Engl J Med 369(14):1317-26 [PubMed]
- Severe, persistent Joint Pain (rare)
VII. Medications
- Sitagliptin (Januvia)
- Dose: 50 to 100 mg/day
- May be dosed with or without food
- Fewer Drug Interactions than Saxagliptin (Onglyza) and Linagliptin (Tradjenta)
- Standard dosing
- Creatinine Clearance >50 ml/min: 100 mg once daily
- Renal Insufficiency
- Consider Tradjenta instead, as does not require Renal Dosing adjustment
- Creatinine Clearance 30-49 ml/min: 50 mg once daily
- Creatinine Clearance <30 ml/min: 25 mg once daily
- Saxagliptin (Onglyza)
- Dose: 2.5 to 5 mg/day
- Significant CYP3A4 Drug Interactions
- Adjust for renal Impairment
- Congestive Heart Failure risk (black box warning)
- Higher risk with pre-existing CHF and renal Impairment
- Linagliptin (Tradjenta)
- Dose: 5 mg/day
- Significant CYP3A4 inducer and P-Glycoprotein Inducer
- No Renal Dosing required
- Alogliptin (Nesina)
- Dose: 25 mg/day
- First Gliptin to be generic (as of 2016)
- Fewer Drug Interactions than Saxagliptin (Onglyza) and Linagliptin (Tradjenta)
- Adjust for renal Impairment
- Congestive Heart Failure risk (black box warning)
- Higher risk with pre-existing CHF and renal Impairment
VIII. Preparations: Combination
- Kanzano (Alogliptin and Metformin)
- Oseni (Alogliptin and Pioglitazone)
- Janumet (Stagliptin and Metformin)
- Trijardy XR (Linagliptin, Empagliflozin and Metformin XR)
IX. Efficacy
- No longterm cardiovascular benefit
- Lowers HBA1C 0.5 to 0.9% (mean 0.6%)
- Contrast with Metformin, Sulfonylureas, GLP-1 Agonists, Pioglitazone lower A1C 1.0 to 1.5% at generic costs
- When combined with other hypoglycemics, its Glucose lowering effects are not additive
