Objective: To investigate frequency of adverse drug reactions (ADR) on HIGURD ®
, a switch OTC product of azelastine hydrochloride, in a three-year post-marketing surveillance study.
Methods: We conducted two surveys in this study a solicited survey with a questionnaire and a survey of spontaneous ADR reports.
Results: A total of 183 cases with 293 ADRs were reported in the solicited survey on 3,453 consumers and a total of 29 cases with 37 ADRs were reported from spontaneous sources. No serious ADRs were reported. Most frequently reported ADRs were somnolence, thirst, malaise, and dysgeusia, all of which are common on azelastine hydrochloride. This study indicated that HIGURD ®
is well tolerated.
Conclusion: This study suggested that efficacy and safety of HIGURD ®
depend on how much consumers understand the contents of “Precautions for Use” section of package insert. It is considered to be effective for safety assurance in an early post-marketing phase that pharmacists inform consumers about appropriate use of HIGURD ®
and ask for the occurrence of ADRs.

BACKGROUND: Listeria monocytogenes (L. monocytogenes) is a rare causative pathogen of brain abscess that is often found in immunocompromised patients. Although patients with supratentorial listerial abscesses showed a longer survival with surgical drainage, the standard therapy for patients with subtentorial lesions has not been established. CASE REPORT: We report herein a patient with supra- and subtentorial brain abscesses caused by L. monocytogenes infection. These abscesses did not respond to antibiotics, and his symptoms gradually worsened. Drainage was not indicated for subtentorial lesions, and the patient was additionally treated with hyperbaric oxygen therapy, which dramatically reduced the volume of abscesses and improved the symptoms. CONCLUSIONS: This is the first report of drastic therapy for a patient with listerial brain abscesses involving combined antibiotics and hyperbaric oxygen therapy. The findings suggest that hyperbaric oxygen therapy is a good option for treating patients with deep-seated listerial abscesses and for who surgical drainage is not indicated.
