Objectives  Drugs are developed for adults, making it difficult to find suitable treatments for children. Hospital pharmacy has developed alternatives to respond to this medical need. The objective of this study is to present a new liquid formulation of ursodeoxycholic acid (UDCA) at a concentration suitable for treatment of neonatal jaundice, and to introduce a novel high pressure liquid chromatography (HPLC) assay method.    Methods  Four formulations have been developed using suspension vehicles due to the low solubility of the active ingredient, and different concentrations of excipient, xanthan gum, needed to facilitate resuspension. An HPLC method coupled to a diode array detector (DAD) has been developed. This method was used to analyze chemical and microbiologic stabilities, as well as physicochemical properties and palatability.    Results  After formulation was chosen, our new HPLC method assay was developed and validated for the quantification of chemical and microbiological stabilities of our product. Both parameters were stable over three months. Palatability has been improved thanks to the addition of universal suspension adjuvants. Odor, appearance and taste were judged pleasant despite a bitter aftertaste, with a persistence of the UDCA resuspension after one month.    Conclusions  Three months after informing neonatal department about the availability of the drug, patients and caregivers are satisfied, and production campaigns are routinely planned.
