Objective To analyze the medication situation of hypertension patients in a community health service center of Chongqing

and to provide basis for guiding the rational drug use of hypertension patients in the community.Methods We collected 3 779 outpatient prescriptions（prescriptions with clinical diagnosis of hypertension）from January 2018 to December 2018 in community health service center.Statistical analysis on the application of oral antihypertensive drugs was conducted in terms of the administration varieties

consumption sum

defined daily dose system（DDDs）

defined daily cost（DDC）

and drug combination etc.Results All prescriptions involved 843 patients with hypertension

including 358 males and 485 females and the age range was 31-97 years.There were 740 patients（87.79%）over 55 years old.The highest sales amount of anti-hypertensive drugs was calcium channel blocker（CCB）（54.66%）

followed by angiotensionⅡreceptor blocker（ARB）（38.67%）.Levamlodipine

Candesartan

Telmisartan ranked at the first 3 place of DDDs.Among 843 patients

386（45.79%）were treated with single drug

336（39.86%）with double drug

and 36（4.27%）with triple drug.The combination CCB and ARB was the most frequently used two-drug regimen in the patients receiving combination therapy（82.73%）

besides CCB+ ARB+βreceptor blocker（β-RB）was the main combination in triple combinations（52.78%）.Conclusion The types of antihypertensive drugs and antihypertensive treatment plan in the community clinic are basically reasonable

but the economy of drug use is not good

and the multidrug combination plan still needs to be further standardized.In addition

clinical pharmacists should pay more attention to the use of CCB and ARB drugs

especially the potential drug interactions

so as to reduce the incidence of adverse drug reactions and improve the compliance of patients.
