OBJECTIVE:To explore the standardized package of Metformin tablets to meet clinical needs. METHODS:Statis-tics was conducted for the utilization data of Metformin tablets in medical and health institutions from 6 cities of China;question-naires were designed to investigate and analyze the evaluation for the suitability of physicians,pharmacists and patients in the pre-scription,deployment and use links to Metformin tablets with different packaging loaded amount in Beijing and Haikou. RE-SULTS:For 0.5 g/tablet,the daily dose of 1.5 g accounted for the largest proportion (32.23%-69.91%) in 5 cities except for Chengdu. Totally 490 questionnaires about package suitability of Metformin tablets in outpatient department were sent out,includ-ing 478 valid questionnaires with effective rate of 97.5%. Results showed that packaging quantity with 4 weeks was considered as appropriate by physicians,pharmacists and patients in Beijing;however,packaging quantity with 1-2 week(s) was considered as appropriate by physicians,pharmacists and patients in Haikou;300-500 tablets of packaging quantity were preferred to be appropri-ate with the matching degree of automatic dispensing machines in both places. CONCLUSIONS:Considering the results in 2 plac-es,for 0.5 g/tablet,2 weeks is appropriate for the packaging loaded amount in outpatient department,that is 0.5 g×45 tablets/box;and 300-500 tablets/box is appropriate for inpatient pharmacies.

Objective To examine the association of serum 25-hydroxyvitamin D levels with arterial stiffness and left ventricular hypertrophy (LVH) in elderly hypertension patients.Methods We recruited 166 elderly patients [mean age,(80.8 ± 6.2) years] with primary hypertension.Arterial stiffness was assessed by carotid femoral pulse wave velocity (cfPWV).Left ventricular mass index (LVMI) was determined according to the Devereux formula.Based on serum 25-hydroxyvitamin D levels,the patients were divided into two groups,the low 25-hydroxyvitamin D group (<20 μg/L)and the high 25-hydroxyvitamin D group (≥20 μg/L).Results Faster cfPWV and larger LVMI values were observed in the low 25-hydroxyvitamin D group as compared with the high 25-hydroxyvitamin Dgroup [(15.00±3.04) m/s vs.(11.26±3.09) m/s;(120.14±25.82) g/m2 vs.(96.74±23.10) g/m2 ; t=-6.79,-5.16,respectively; both P=0.000].Multiple liner regression analysis showed that the 25-hydroxyvitamin D level was independently associated with LVMI (β=0.215,P=0.001) and cfPWV (β=-0.469,P<0.001).Conclusions Serum 25-hyroxyvitamin D is independently associated with arterial stiffness,LVH Vitamin D may play an important role in the pathogenesis of arterial stiffness and LVH in elderly hypertension patients.
