Loxoprofen (Loxonin®) is a widely administered non-steroidal anti-inflammatory drug (NSAID) in Japan, with annual sales exceeding 50 billion Japanese yen. Although it is a very versatile drug and is often administered to breastfeeding women, the information available regarding its mammary gland transfer is inadequate.Therefore, in this study, we analyzed loxoprofen levels in the blood and milk of four breastfeeding women who received the drug for pain relief. These women visited the Obstetrics and Gynecology Department of Hanwa Sumiyoshi General Hospital for consultation or a cesarean section.One tablet of Loxonin® (loxoprofen 60 mg) was orally administered to each of the four women, and blood and milk samples were collected 0, 30, 90, 150 and 330 min after drug administration. Twenty microliters of ethanol was added to the blood and milk samples (10 μL), and the mixture was centrifuged at 12000 g for 15 min. The supernatant was analyzed by high-performance liquid chromatography (HPLC).Loxoprofen levels in blood peaked 90 min after its oral administration in all four patients, with the highest level being 4.5 μg/mL in patient II, whereas loxoprofen level in milk was below the detection limit (0.1 μg/mL) at all time points. Taken together, the data suggest low mammary gland transfer of loxoprofen, and thereby a low lactation risk.

&nbsp;&nbsp;Loxoprofen (Loxonin^&reg;), an antipyretic painkiller, was approved as an over-the-counter (OTC) drug (Loxonin^&reg;-S) in January 2011. With regard to self-medication using OTC drugs, the information that pharmacists provide to consumers is very important. Although loxoprofen is a very versatile drug and can be used during breastfeeding, information regarding its mammary gland transfer is inadequate. In this study, we established a simple method to evaluate mammary transfer of drugs, and compared loxoprofen's mammary gland transfer with that of aspirin. Loxoprofen 12 mg/kg and aspirin 132 mg/kg was orally administered to mother mice (ddY), and blood and milk samples were collected. Twenty microliters of ethanol was added to the blood and milk samples (10 &mu;L), and the mixture was centrifuged for 15 min (12000 <i>g</i>); the supernatant was analyzed by high-performance liquid chromatography. Since aspirin was immediately metabolized, we analyzed salicylic acid concentrations. Maximum concentration of loxoprofen was observed at around 15 min after its oral administration, with the concentrations in the blood and milk being 2.9 and 0.5 &mu;g/mL, respectively. The drug was metabolized promptly thereafter. In contrast, maximum concentration of salicylic acid was observed at 30 min after aspirin administration, with the concentrations in the blood and milk being 187.2 and 64.4 &mu;g/mL, respectively. These concentrations remained constant from 60 to 120 min. Salicylic acid could be detected 240 min after aspirin administration. Thus, mammary gland transfer of loxoprofen is lower than that of aspirin, suggesting that loxoprofen does not accumulate in milk.<br>

With regard to proper drug use in home care, the failure of approximately half of all elderly patients to comply with their doctor’s medication instructions and many other issues have been reported. However, pharmacists’ involvement in home care support remains inadequate, as highlighted by a Ministry of Health, Labor and Welfare report which noted the lack of full utilization of pharmacists in community medicine as well as the fact that home nurses often have to manage their patients’ medications. The Setsunan University Faculty of Nursing was established in 2012, and the university’s Faculties of Pharmaceutical Sciences and Nursing collaborate in their educational activities. To increase pharmacists’ involvement in home care support, we launched a project to create a home care support model in which pharmacists and nurses work in collaboration, utilizing their respective faculty resources. In this study, we conducted a questionnaire survey of pharmacies and visiting nurse stations in Osaka Prefecture regarding the present status of and problems related to pharmacists’ participation in the home care system and visiting nurses’ current involvement in medication management, as well as what is expected of pharmacists. Based on these results, we are constructing a model in which Faculties of Pharmaceutical Sciences and Nursing collaboratively support the home care system with the aim of establishing the role that universities should play in a comprehensive regional care program.
