Lyumjev Kwikpen (Insulin Lispro aabc) Vs Insulin Lispro

Insulin Lyumjev

Insulin Lyumjev and Insulin Lyumjev Junior

Insulin Lyumjev is a modified form of Insulin Lispro. It is actually Insulin Lispro plus the addition of citrate and treprostinil. It is ultra-short-acting insulin and has a faster onset of action compared to Insulin Lispro. The faster onset of action is attributed to the citrate and treprostinil molecules that cause increased absorption of Insulin Lyumjev through the skin.

Rapid Acting Insulin (Fast acting Insulin or Ultra-Short acting Insulin)

Insulin Lyumjev or Lispro-aabc Indications:

It is indicated for the treatment of Diabetes Mellitus Type 1 and Type 2. It is indicated for controlling post-meals hyperglycemia.

Formulations and administration:

Insulin Lispro-aabc is available as U-100 Kwikpen and Tempo Pen, U-200 Kwikpen, and U-100 Junior Kwikpen. The maximum dose administered per injection is 60 units for U-100 and U-200 kwikpen and U-100 Tempo Pen and 30 units for U-100 Junior Pen.

Insulin Lispro-aabc is administered into the skin like most other insulins. The best sites are the anterior abdomen, upper arms, and thighs. The dose is increased in increments of 1 unit per dose in adults and 0.5 units per dose in children using Insulin Lispro-aabc U-100 Junior Kwikpen until the target blood sugars are achieved or the maximum units per dose are administered.

Insulin Lyumjev U-100 but not U-200 can also be mixed with 0.9% Saline and dextrose water and administered intravenously. The diluted insulin should not be administered intravenously if its concentration is below 1 unit/ml.

Comparing Insulin Lyumjev (Lispro-aabc) Vs Insulin Lispro:

Insulin Lispro aabc also called Insulin Lyumjev is almost identical to Insulin Lispro (Insulin Humalog and Insulin Admelog with minimal differences.

Formulations available:

  • Insulin Lispro: Insulin Humalgo and Admelog
  • Insulin Lispro-aabc: Insulin Lyumjev

Onset Of Action:

  • Insulin Lispro: 30 minutes in T1DM and 45 minutes in T2DM.
  • Insulin Lispro-aabc: 15 – 17 minutes depending on the dose administered.

Peak effect:

  • Insulin Lispro:
    • Insulin Humalog: 2.1 hours
    • Insulin Admelog: 2.4 hours
  • Insulin Lispro-aabc:
    • 120 minutes when administered in a dose of 7 units
    • 138 minutes when administered in a dose of 15 units
    • 174 minutes when administered in a dose of 30 units

Bioavailability when administered subcutaneous:

  • Insulin Lispro: 55 – 77%
  • Insulin Lispro-aabc: 65%

The duration of action:

    • Insulin Admelog: About 6.9 hours.
    • Insulin Humalog: 5.7 – 6.6 hours.
    • Insulin Lyumjev: 4.6 – 7.3 hours.

Efficacy of Insulin Lyumjev (Lispro-aabc) compared to Insulin Humalog:

Insulin Lyumjev was compared in two clinical trials with Insulin Lispro. The first trial evaluated its efficacy in T1DM patients.

Insulin Lispro vs insulin Lyumjev administered at mealtime in T1DM.

In patients with T1DM, mealtime administration of Insulin Lyumjev resulted in a clinically significant reduction in the glycated hemoglobin at 26 weeks of the trial.

Insulin Lyumjev was also studied in patients with T2DM. It was compared with Insulin Humalog (Insulin Lispro). All patients received basal insulin along with mealtime rapid-acting insulin.

Both Insulin Lyumjev and Insulin Humalog had a comparable reduction in the glycated hemoglobin as seen here:

Side effects of Insulin Lyumjev:

Insulin Lyumjev, like other insulin, reduced the plasma blood glucose. Thus, hypoglycemia is the most common effect or side effect of insulin Lyumjev. It also causes the intracellular shifts of potassium and may result in hypokalemia especially when administered as intravenous infusions.

Other common side effects of insulins including insulin Lyumjev include lipo-hypertrophy at the site of administration. This is especially a problem in patients who inject the insulin repeatedly into one skin area.

Patients may also report weight gain and sometimes may develop antibodies against the insulin. This could result in an allergic type of reaction at the site of administration and loss of efficacy.

In Summary:

Insulin Lyumjev is ultra-short acting insulin with better bioavailability, rapid onset of action, and comparable post-meal glycemic control when compared with Insulin Lispro.
