Pharmacist blood pressure management programs using telemonitoring systems are useful for monitoring side effects of antihypertensive drugs in a community pharmacy

Health-promoting services provided in pharmacies: A systematic review

Pharmacies are a major component of health systems and a major part of health service provision. This study aimed at identifying and introducing the potentials of pharmacies in health promotion. This was a systematic review that searched PubMed, Web of Science, Science Direct, SID, Magiran, and IranMedex from February 1990 to September 2018 for related materials. The main search keywords were (pharmacy services), (community pharmacy services), (retail pharmacy services), (pharmacy practice intervention). Inclusion was limited to those papers that discussed the health-promoting services provided in the pharmacies. The quality of included papers was assessed by the Critical Appraisal Skills Program checklists. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses chart was followed in all stages of the study. Of the 4156 papers retrieved, 18 met the inclusion criteria and included in the analysis. Study findings were categorized into three main categories: Health and prevention services, services related to treatments, and the awareness about the pharmacies' functions. The health and prevention category consisted of education, vaccination, screening and prevention of diseases, family planning, blood pressure monitoring, quitting smoking, limiting alcohol, and weight management. The treatment-related services consisted of adherence to medication, medication consultation, minor pains, and emergency medical services. Pharmacies can provide a wide variety of services besides the medications. Purposeful development of the services provided in the pharmacies and involving them in an extended array of services may accelerate the health promotion activities of the health system and result in improved quality of life and decreased costs. To do so, the legal, educational-skill, and pricing challenges should be resolved.

Antihypertensive constituents in Sanoshashinto

It has been reported that Sanoshashinto (SanHuangXieXinTang, 三黃瀉心湯), which is composed of Rhei Rhizoma, Scutellariae Radix, and Coptidis Rhizoma, exhibits vasorelaxant effects in vitro and lowers blood pressure of patients. Based on this discovery, in this study, a mixture containing those three materials and combinations of them were extracted with methanol, and the extracts were fractionated into different parts. Effects of all extracts and fractions on high concentration of potassium chloride (High K⁺)- or noradrenaline (NA)-induced contractions of isolated rat aortic rings or helical strips were examined. Qualitative and quantitative HPLC analyses of the extracts and the fractions revealed that the contents of baicalin and berberine in Sanoshashinto methanol extract (SHXXTM) were higher than those of the other constituents. All pharmacological and HPLC data were analyzed by principal component analysis (PCA) software and the results indicated that baicalin, berberine, palmatine, baicalein, and wogonoside contributed significantly to the pharmacological activity. Furthermore, spontaneously hypertensive rats (SHRs) that were orally given SHXXTM or a baicalin–berberine combination showed significantly reduced increase in the rate of systolic blood pressure (SBP) compared to the control group. These findings suggested that Sanoshashinto has significant vasorelaxant effects in vitro and antihypertensive effects in vivo, and baicalin and berberine, which were the principal constituents of Scutellariae Radix and Coptidis Rhizoma, were the main antihypertensive constituents in Sanoshashinto. It was speculated that baicalin and berberine produced vasorelaxant effects by activating the NO/cGMP pathway and that the BK_Ca channel and the DAG/PKC/CPI-17 pathway were also involved.
