Hypertension is a chronic disease that is an increase in systolic and diastolic blood pressure 140/90 mmHg. The prevalence of hypertension patients is increasing at the Puskesmas, so it is necessary to observe the usage profile of antihypertensive drugs. This research is needed as initial data to monitor the use and procurement of drugs. This study aims to determine the profile of the use of antihypertensive drugs which includes the name of the drug and the rules of antihypertensive drugs.
