Stability of amphotericin B in 5% dextrose injection at concentrations used for administration through a central venous line


, : Stability of amphotericin B in 5% dextrose injection at concentrations used for administration through a central venous line. American Journal of Hospital Pharmacy 48(2): 283-285

The stability of amphotericin B in 5% dextrose injection was studied at concentrations used for administration through a central venous line. Amphotericin B 60, 80, and 100 mg was diluted in 50 mL of 5% dextrose injection; final mean +/- S.D. concentrations after adjustment for total volume were 0.92 +/- 0.01, 1.20 +/- 0.03, and 1.40 +/- 0.03 mg/mL, respectively. For each concentration, six admixtures were prepared; of these, three were stored at 25 degrees C and three at 6 degrees C. Amphotericin B concentration was tested at 0, 4, 12, 24, and 36 hours by stability-indicating high-performance liquid chromatography. The admixtures were inspected visually at each time point for precipitation, turbidity, gas formation, and color change, and the pH was measured. Concentrations of amphotericin B remained within 3% of initial concentrations at each time point at both storage temperatures. No precipitation, turbidity, gas formation, or color change was observed, and no changes in pH were measured. Amphotericin B in 5% dextrose injection was stable at concentrations of 0.92, 1.20, and 1.40 mg/mL when stored at 6 and 25 degrees C for up to 36 hours.

Relationships with blood pressure and cardiovascular structure. The angiotensin II type I (AT-1) receptor has a key role in mediating the vasoconstrictor and growth-promoting effects of angiotensin II. It has been reported that a polymorphism of the AT-1 receptor gene (an A/C transversion at position 1166) may...

It is intuitively expected that an enhanced light extraction of a scintillator can be easily achieved by photonic crystal structures. Here, we demonstrate a modified timing characteristic for a detection system induced by enhanced light extraction...
