The physicochemical and pharmaceutical properties (pH, peel force, water-vapor permeability, and stretchability) of brand-name and generic ketoprofen products were evaluated and compared. The pHs of Mohrus as a brand-name product and Teikoku as a generic product were low (about 4). Among the other generic products, Patell and Nichi-Iko had a pH of about 4.3 while Frestol, Raynanon, BMD, and Touchron showed a pH of 4.6-5.2, which was in the pH range of normal healthy skin (4.5-6.5). The adhesive force was high (≥ 1.38) for Mohrus as a brand-name product as well as for Teikoku and Patell as generic products, but it was low (≤ 0.57) for the other 5 generic products. The water-vapor permeabilities of Mohrus as a brand-name product and Teikoku and Patell as generic products were low, being less than 1/6 of those for the other 5 generic products. Among the 5 generic products, BMD showed the highest water-vapor permeability (1,330 g/m2), and the other products also showed a value ≥ 1,100 g/m2. The elongatedness of Mohrus was the lowest (15.5 cm), and that of Raynanon was the highest (24.5 cm); the difference was 9 cm. In this study, the physiochemical and pharmaceutical properties of ketoprofen tapes were clarified, which will allow pharmacists to provide products according to the needs of each patient when a brand-name product is changed to a generic one.

We measured the pH, water-vapor permeability, adhesive force, peeling-force, elongation rate, support flexibility, and peeling time of medicinal and over-the-counter (OTC) tape preparations containing felbinac. When measuring the pH of each preparation, Felnabion (pH 4.5) was weakly acidic, and EMEC and Tokuon (pH 7.0) were neutral. When measuring the water-vapor permeability of each preparation, that of a generic product, EMEC (380 g/m2/24h), was twice as high as that of a brand-name product, Seltouch (189 g/m2/24 h). The adhesive force was measured using the ball tack test. The adhesive forces of OTC drugs, Salomethyl, Homepass, and Tokuhon (1.04 g), were higher than that of Seltouch (0.06 g). Concerning peeling-force measurement, the peeling-forces of a generic product, Falzy (4.15 N), and an OTC drug, Omuneed (4.89 N), were higher than that of Seltouch (0.91 N). The elongation rates of a generic product, Sumilu (319%), and OTC drugs, Nabolin (298%) and Homepass (299%), were higher than that of Seltouch (251%), but that of Tokuhon (72%) was lower. The support flexibilities of EMEC (150 degrees) and Tokuhon (131 degrees) were higher than that of Seltouch (96 degrees). In addition, the peeling time of Seltouch was 120 min or more, whereas those of EMEC and Nabolin were 1.4 and 0.2 min, respectively. These results suggest that the differences in pharmaceutical properties, such as the pH, water-vapor permeability, adhesive force, peeling-force, elongation rate, support flexibility, and peeling time, among the preparations markedly influence patients' subjective comfortableness. The results of this study facilitated individuals’ comfortableness-matched drug selection.

This study was conducted in order to establish a health management method for the elderly in a community through follow-ups of bone mineral density (BMD) measurement results over a 1-year period based on BMD measurements performed by pharmacists and a guidance program. Regarding BMD measurement results, the percent young adult mean (%YAM: mean BMD in healthy persons of the same sex aged between 51 and 82 years old) significantly increased in Period I, during which the intervention by pharmacists was performed (6 months after the start of measurements), but significantly decreased in Period II, during which this intervention was not performed (between 7 and 12 months after the start of measurements). Based on these results, lifestyle improvements were effective in Period I regardless of sex or age; however, it may be important to maintain an improved diet and subject motivation in the future. The results of this study suggest that community pharmacists play an important role in community medicine through positive intervention for local residents' health support.

We measured and compared the physicochemical properties (pH, yield value, and squeeze force) of a drug for dermatomycosis, terbinafine hydrochloride-containing cream (brand-name product), and 12 generic products to clarify the characteristics of each product. On pH measurement, the pH value of the brand-name product, Lamisil, was 4.8, and those of the generic products ranged from 4.3 to 5.5, showing no marked difference. Furthermore, the yield value of Lamisil, as an index of cream ductility, was 122.2 dyn/cm2, and those of the generic products ranged from 42.1 to 1,621.5 dyn/cm2. In particular, the value of a generic product, Taiyo (42.1 dyn/cm2), was significantly lower, whereas that of another one, Viras (1,621.0 dyn/cm2), was significantly higher. In addition, the squeeze force was measured by attaching a HapLog® to the thumb and second finger. The value of Lamisil was 12.9 N, and those of the generic products ranged from 8.0 to 15.4 N. The values of generic products, Mylan (8.6 N), Tebinaceil (9.0 N), and Kelger (8.0 N), were significantly lower, whereas that of another one, Viras (15.4 N), was significantly higher. These results showed that there were marked differences in the pharmaceutical properties between the generic and brand-name products. The above pharmaceutical characteristics of drugs facilitated the presentation of reasons for differences in the sense of use, which characterizes external preparations, suggesting that products appropriate for individual patients can be recommended.
