Stability assessment and content determination test of oral liquid forms of beclomethasone dipropionate prepared in hospital pharmacy.

Objectives: Oral beclomethasone dipropionate (BDP) is known for its use as a therapeutic medicine for gastrointestinal graft-versus-host disease (GI-GVHD). Despite growing demand for oral BDP formulation, no commercial forms have yet been marketed. Therefore, at the Tokyo Metropolitan Cancer and Infectious Disease Centre Komagome Hospital, pharmacists prepare oral liquid forms of BDP for patients with upper GI-GVHD.

Analytical characterization and differentiation between threo- and erythro-4-fluoroethylphenidate.

Purpose: Methylphenidate analogs appeared on the drug market during the last years. Its analogs contain two chiral centers and, thus, have potential varying configurations (i.e.

[Improvement Method of Confirmation Test of the In-pharmacy Formulation as Topical Medicine No. 37-①].

Topical Medicine No. 37-① is one of the in-pharmacy formulation that specifies a confirmation test (referred hereafter as the conventional method) to identify its ingredient diphenhydramine (DH) by colorimetric test. However, the conventional method is environmentally unfriendly due to the large amount of sample and organic solvent used, and the extraction process is complicated.

Versatile whole-organ/body staining and imaging based on electrolyte-gel properties of biological tissues.

Whole-organ/body three-dimensional (3D) staining and imaging have been enduring challenges in histology. By dissecting the complex physicochemical environment of the staining system, we developed a highly optimized 3D staining imaging pipeline based on CUBIC. Based on our precise characterization of biological tissues as an electrolyte gel, we experimentally evaluated broad 3D staining conditions by using an artificial tissue-mimicking material.
