The aim of this study is to investigate the status of Japanese pharmacists' awareness and attitude toward blood pressure (BP) measurement at home (HBP) and in the pharmacy. Of the 708 community pharmacists and the 117 hospital pharmacists, more than 90% of pharmacists answered that HBP was equally important to or more important than clinic BP, 71.9% (community) and 48.7% (hospital) recommended HBP measurement to the hypertensive patients, and about 15% correctly recognized the reference values of HBP hypertension. Among community pharmacists, 54.0% answered that BP-measuring devices were available in their pharmacy. More aggressive promotion of HBP measurement among pharmacists is warranted.
