      Hospital formulation has several advantages, including the flexibility of customization as per the disease state or the patients’ precise requirements. However, compared with commercial formulations, hospital formulations are usually not under the same level of quality check. In the present study, we tested mixed powder formulations prepared in a hospital pharmacy using Raman spectroscopy to investigate the feasibility of applying Raman spectroscopy as a quality-control tool of hospital formulations. For this purpose, we first established a numerical evaluation method to determine the uniformity of a powder mixture using Raman chemical imaging data with atropine sulfate/lactose mixture samples and revealed that the mixing uniformity correlated to the experience level of the pharmacist. Next, we developed a content quantification method in a one-dose packaged powder formulation by measuring the Raman spectra from the outside of the package. Because this method allows for quantification of the components inside the package in a non-destructive and non-contact manner, it can be applied for content confirmation after one-dose packaging. Using this method, the content uniformity of the mixed powder formulation in the one-dose package was compared between the formulations prepared by the pharmacists and those prepared by a pharmacy robot. Our study indicates the possibility of applying Raman spectroscopy as a quality-control tool of hospital formulations. Studies on further applications of Raman spectroscopy in the field of clinical pharmacology are expected.
