Intravenous
Nesiritide (Natrecor) has no standard bacteriostatic water volume on file, so there are no syringe units to calculate here. Dosing runs 2mcg/kg to 2mcg/kg per administration, iv bolus + 0.01 mcg/kg/min infusion.
If your product does arrive as a powder, use the universal reconstitution calculator and enter your own vial size and water volume.
Nesiritide (Natrecor) is a recombinant BNP that lowers pulmonary pressures within 15 minutes in acute heart failure. FDA-approved in 2001 but discontinued after ASCEND-HF (n=7,141) showed no mortality benefit. Hospital-only IV drug with no approved community use or self-administration potential.

Nesiritide is discontinued from the US market. This page exists for clinical reference, not practical sourcing guidance. You won't find it through any legitimate supply channel. When it was available, each 1.5 mg vial got reconstituted with 5 mL of diluent pulled from a 250 mL IV bag (D5W, normal saline, or 5% dextrose/0.2% NaCl). That gave 0.32 mg/mL in the vial. The entire contents then went back into the 250 mL bag for a final concentration of roughly 6 mcg/mL. For a 70 kg patient: the bolus is 2 mcg/kg = 140 mcg, which is about 23 mL of the 6 mcg/mL solution, given over 60 seconds. Maintenance runs at 0.01 mcg/kg/min = 0.7 mcg/min = 7 mL/hr on the infusion pump. The thing most residents miss: stopping the infusion doesn't stop the hypotension. Plan for 2+ hours of blood pressure monitoring after you turn it off. And never run it through the same line as heparin or furosemide; it precipitates.
