The PTX concentration was approximately 5.5% lower when combined with undiluted calcium gluconate injection (100 mg/mL). The PTX concentration ratios for all other combinations, including diluted calcium gluconate injection (50 mg/mL), were in the range of 99.5%–102%.Conclusion In simulated Y-site conditions, PTX was found to be compatible with 15 parenteral medications and six total parenteral nutrition solutions. Based on PTX concentration tests, it would be prudent to avoid mixing PTX with undiluted calcium gluconate injection.
