- Insulin
- Preparations
- Insulin Glargine (Lantus)
- Information below is based on Lantus
- Most closely matches 24 hour coverage
- Detemir (Levemir)
- Similar pharmacokinetics as Lantus
- Less burning on injection compared with Lantus
- Binds and released from circulating albumin
- Most consistent basal Insulin day to day
- Duration varies by dose (bid may be preferred)
- Precautions
- Basal Insulin does not cover meal times
- Use in combination with agents to cover meals
- Rapid acting Insulin (e.g. Lispro)
- Oral agents (Sulfonylureas, Metformin, Glitazone) or
- Switch to basal/bolus when Glargine >0.5 units/kg
- Pharmacokinetics
- Onset: 1 hour
- Duration: 21 to 24 hours
- May require divided dosing bid to maintain basal rate
- Peak: No peak
- Flat action profile throughout duration
- Mimics continuous Insulin Infusion
- Adverse effects
- Less nocturnal Hypoglycemia than other Insulins
- Lower post-prandial Glucose
- Dosing
- Starting dose (no prior Insulin)
- Hemoglobin A1C <8%: 0.1 units/kg
- Hemoglobin A1C >8-10%: 0.2 units/kg
- Hemoglobin A1C >10%: 0.3 units/kg
- Old regimen for starting dose (use units/kg as above instead)
- Type I Diabetes: 10 Units qhs
- Type II Diabetes: 10-14 Units qhs
- Conversion from other long-acting Insulin
- NPH/Ultralente qhs: start Lantus at same dose
- Consider starting Lantus at 80% of prior NPH dose
- NPH bid: Start Lantus at 80% of total daily NPH dose
- Adjustment based on fasting plasma Glucose (FPG)
- Protocol 1
- FPG <70 mg/dl for 3 days: Decrease Lantus 1-2 units
- FPG 140-250 for 3 days: Increase Lantus 2-4 units
- FPG >250 for 3 days: Increase Lantus 4-8 units
- Protocol 2
- FPG <80 for 3 days: Decrease Lantus by 2 units
- FPG 100-120 for 3 days: Increase Lantus by 2 units
- FPG 120-140 for 3 days: Increase Lantus by 4 units
- FPG 140-180 for 3 days: Increase Lantus by 6 units
- FPG >180 for 3 days: Increase Lantus by 8 units
- Timing of dose for Lantus
- Studies gave Lantus at bedtime to avoid confusion
- Lantus is most effective if given in the morning
- Delivery Devices: OptiClik Pen
- Pens are free from Aventis
- Phone: 800-207-8049
- Pens ease Insulin delivery
- Lantus in cartridges costs 2 cents/unit more than vial
