Review of drug utilization patterns in NICUs worldwide.

Overall, the types of medicines used in NICUs worldwide are similar, with consistent reports on the common use of antibiotics, caffeine and vitamins. However, it cannot be definitively stated that the findings of the review accurately depict current practice in NICUs, due to the limited amount of published literature available. There are several areas of concern that warrant further investigation to improve rational use of medicines in the neonatal populations, including high use of antibiotics and off-label and unlicensed medicines.
