How to Reconstitute ARA-290
Updated today
ARA-290 is supplied as a 10 mg lyophilized (freeze-dried) vial and must be reconstituted with bacteriostatic water before use. Adding 2 mL to a 10 mg vial yields a concentration of 5 mg/mL — so a 250 mcg reference dose is 5 units on a standard U-100 insulin syringe. Use more water for a more dilute, easier-to-measure solution, or less for a more concentrated one; the amount of compound in the vial is the same either way. Adjust the calculator below to match your exact vial size and target dose.
| Dose | Units (U-100) | Volume |
|---|---|---|
| 250 mcg | 5 units | 0.05 mL |
| 500 mcg | 10 units | 0.1 mL |
| 1000 mcg | 20 units | 0.2 mL |
| 2000 mcg | 40 units | 0.4 mL |
