Stability of milrinone lactate in the presence of 29 critical care drugs and 4 i.v. solutions.
The stability of milrinone lactate in the presence of 29 critical care drugs during simulated Y-site injection and in 4 i.v. solutions was studied. Ten milliliters of milrinone 400 microg/mL (as the lactate salt) was combined with 10 mL of each of 29 commonly used critical care drugs in 5% dextrose injection. Also, mixtures containing milrinone 400 microg/ mL in lactated Ringer's injection, 5% dextrose injection, 0.45% sodium chloride injection, and 0.9% sodium chloride injection were prepared. ⋯ In all the mixtures, milrinone retained more than 96% of its initial concentration, and the other drugs retained more than 97% of their initial concentrations. Milrinone 400 microg/mL in 5% dextrose injection and 29 critical care drugs were stable for four hours at 22-23 degrees C during simulated Y-site administration. Milrinone 400 microg/mL was stable in lactated Ringer's injection, 5% dextrose injection, 0.45% sodium chloride injection, and 0.9% sodium chloride injection for seven days at 22-23 degrees C.
