Introduction
This prepapration is specifically indicated in neonatology (i) to enhance glucose uptake in glucose intolerant patients and (ii) to adapt hydric needs regarding intakes from total parenteral nutrition mixture. To meet regulatory requirements and have ready to use prepartion with an expiration date, a stability study was realised for 1 year.
Materials and method
This hospital preparation was made under aseptic conditions associated with a sterilizing filtration and autoclaving. The sterile solution has been conditioned in 50 ml glass type II bottle containing in galenic formulation 138,8 mM of glucose and 35,1 mM of sodium chloride. Prepared bottles were stored at 22 ± 3°C in a dry place.
To assess stability, the physical-chemicals controls (pH, osmolality, sodium, chlorides, sub-visible particles, glucose and hydroxy-methyl-furfural (5HMF: glucose degradation product)) and microbiologicals (bacterial endotoxins and sterility) were realized from a pilot batch of 100 bottles.
Results and discussion
Neither significant decrease of glucose concentration and sodium concentration nor pH and osmolality variation were observed for 1 year study. Throughout the study, the content of 5-HMF, remained below the concentration harmful for Human. The sub-visible particles, the bacterial endotoxin and sterility were in accordance with the European Pharmacopoeia attesting limpidity, apyrogenicity and sterility of this injectable preparation.
Conclusion
the injectable preparation was stable over 1 year at 22 ± 3°C, ensuring to safe for intravenous administration for prematures.
