Key takeaways

At the reference preset of a 5mg Larazotide vial reconstituted with 2 mL of bacteriostatic water, a 0.5mg dose measures 20 units on a U-100 insulin syringe.

Larazotide is an octapeptide investigated for celiac disease and intestinal-barrier dysfunction.

How to use this calculator
  1. 1. Vial — the peptide amount printed on the vial, in milligrams.
  2. 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
  3. 3. Dose — the single dose being measured, in milligrams.
  4. 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

About

What is Larazotide?

Larazotide is an octapeptide investigated for celiac disease and intestinal-barrier dysfunction. It is most often studied as an oral formulation; injectable use is uncommon and reference doses here are illustrative only.

Reference dose ranges
0.5 mg≈ 20 U-100 units (at 5mg / 2mL)
1 mg≈ 40 U-100 units (at 5mg / 2mL)
Reconstitution

How it's typically prepared

Larazotide is most often delivered orally. Reconstitution math may not apply to your formulation.
