The Isisis study was for the hypertonic saline (7%) vs. 0.9% for newborns up to. 16 months. They have done the same clinical trials for adults and children. When my daughter finished up the study last week we were informed that we might not be able to get the 7% anymore. The company isnt making any money ( pari) there is an appeal going on rigjt now amd the decision will be made in a couple of weeks. In the last couple of days of her being on it I have been impressed. there is nothing that sick kids can do and there us no other company in Canada that makes it. I have 4 other refills (12 boxes) that I could fill if it is discontinued but I want to figure something out for back.up. The only one I could find on amazon was 0.9.
