From descriptions on the package inserts and interview forms accessible on the home page of the Pharmaceuticals and Medical Devices Agency (PMDA), the characteristics of active pharmaceutical ingredients, pharmaceutical production, and formulations of 106 glaucoma therapeutic agents currently used in clinical practice in Japan were analyzed. Since eye drops are a sterile preparation and are administered multiple times, their efficacy, safety, stability and preservation must be taken into consideration. The pH (4-8) and osmotic pressure (0.6-1.6) were well controlled within a fixed range and some additives were compounded in the eye drops for the purpose of making the users feel more comfortable. It was also found that there was a difference in the use of solubilizing agents and preservatives between domestic and global pharmaceutical companies. There has been no article to compare the eye drop formulations of glaucoma therapeutic agents for 45 years; therefore, this paper will help to show future directionality of the preparation development of eye drops.

Flowability is one of the most important parameters of pharmaceutical powders during the handling and preparation of solid dosage forms. It is especially important to characterize the very poor flowability that some herbal powders show. In this study, the flowability of a traditional herbal powder formulated as an antitussive and expectorant was examined. This formulated herbal powder and two excipient powders, precipitated calcium carbonate and anhydrous dibasic calcium phosphate, were evaluated using two instruments. A shearing test, a wall friction test and a dynamic flowability test were performed with Powder Rheometer FT4 (Freeman Technology, Tewkesbury, UK). Internal friction and wall friction were measured. BFE (basic flow energy), SI (stability index) and FRI (flow rate index) were also measured. Angle of repose, bulk density, tapped density, angle of spatula and cohesiveness were measured with a Powder Tester (Hosokawa Micron, Osaka, Japan). The results were used to calculate Carr's Index values and compressibility, which in turn revealed that this herbal powder had poor flowability.
