Potentially harmful excipients in neonatal medications: a multicenter nationwide observational study in Japan.

BACKGROUND: A multicenter investigation of neonate exposure to potentially harmful excipients (PHEs) in neonatal intensive care units (NICUs) in Japan has not been conducted. METHODS: A multicenter nationwide observational study was conducted. Neonate patient demographic data and information on all medicines prescribed and administered during hospitalization on 1 day between November 2019 and March 2021 were extracted from the medical records. Nine PHEs, paraben, polysorbate 80, propylene glycol, benzoates, saccharin sodium, sorbitol, ethanol, benzalkonium chloride, and aspartame, were selected. PHEs were identified from the package insert and the Interview Form. The quantitative daily exposure was calculated if quantitative data were available for each product containing the PHE. RESULTS: Prescription data was collected from 22 NICUs in Japan. In total, 343 neonates received 2360 prescriptions for 426 products containing 228 active pharmaceutical ingredients. PHEs were found in 52 (12.2%) products in 646 (27.4%) prescriptions for 282 (82.2%) neonates. Benzyl alcohol, sodium benzoates, and parabens were the most common PHEs in parenteral, enteral, and topical formulations, respectively. Quantitative analysis showed that 10 (10%), 38 (42.2%), 37 (94.9%), and 9 (39.1%) neonates received doses exceeding the acceptable daily intake of benzyl alcohol, polysorbate 80, propylene glycol, and sorbitol, respectively. However, due to the lack of quantitative information for all enteral and topical products, accurate daily PHE exposure could not be quantified. CONCLUSIONS: Neonates admitted to NICUs in Japan were exposed to PHEs, and several of the most commonly prescribed medicines in daily clinical practice in NICUs contained PHEs. Neonate PHE exposure could be reduced by replacing these medicines with available PHE-free alternatives.

[Usage of gastric antisecretory drugs in palliative care of lung cancer patients].

Non-steroidal anti-inflammatory drugs(NSAID)and steroids are important drugs that are the most frequently prescribed medications for the relief of cancer pain. However, there is overwhelming evidence that these drugs cause various forms of gastric mucosal injury. Based on clinical experience, gastric antisecretory drugs such as the proton pump inhibitor(PPI)and the histamine-H2 receptor antagonist(H2RA)are widely used to avoid the gastrointestinal problems caused by NSAID and steroids. There are individual differences in how physicians use PPI and H2RA. In the present study, we retrospectively examined PPI and H2RA usage in the palliative care of 83 lung cancer patients, who were routinely prescribed an NSAID alone (single group)or a combination of an NSAID with a steroid(combination group). We also administered a questionnaire survey to 25 prescribing physicians specializing in respiratory medicine. The proportion of physicians prescribing a PPI prophylactically in the combination group was significantly higher than that of the single group. According to answers in the questionnaire survey, PPI prescribed by physicians in the single group was determined by the performance status and history of gastrointestinal problems in patients. Regardless of such factors, in the combination group, PPI was deliberately prescribed with steroids. Further investigation is needed to examine the clinical effects of PPI in palliative care, so as to establish more appropriate use of both PPI and H2RA.

[Evaluation of the symptoms, adherence and satisfaction after pharmaceutical care at asthma clinic for outpatient].

In the present study, we investigated whether counseling at an outpatient asthma clinic improved asthma symptoms, adherence and patient satisfaction: The asthma control test (ACT) and asthma control questionnaire (ACQ) were used to assess subjective symptoms, 10-item version of the drug attitude inventory (DAI-10) was used to determine medication adherence, and 8-item Japanese version of the client satisfaction questionnaire (CSQ-8J) was used to ascertain patient satisfaction. All scores of inhalation technique, PEF (peak expiratory flow) value/predicted PEF value (%), ACT, ACQ and DAI-10 in 26 patients with asthma increased after counseling at the outpatient asthma clinic compared to those before counseling. The average CSQ-8J score of 28 points (highest possible score: 32 points) indicated that the patients were satisfied with services provided by this clinic. These results indicate that counseling provided by pharmacists at the outpatient clinic is a valuable way improving subjective symptoms, lung function and medication adherence. These results also indicate that counseling at the asthma clinic by pharmacists improves the quality of life of patients with asthma.
