S-amlodipine in Essential HypertensIon and Assessment of Blood Pressure Targets Achievement

Study Overview
=================
Brief Summary
-----------------
Evaluate the ratio(%) of patients whose blood pressure measured at 6 months from the baseline was confirmed to be within the target blood pressure range according to the 2022 hypertension treatment guidelines for essential hypertension patients who received the study drug.

Detailed Description
-----------------
Primary purpose: Evaluate the ratio(%) of patients whose blood pressure measured at 6 months from the baseline was confirmed to be within the target blood pressure range according to the 2022 hypertension treatment guidelines for essential hypertension patients who received the study drug. Secondary purpose: Evaluate the efficacy by comparing the change in blood pressure for each drug pattern (monotherapy or combination therapy) at 6 months after administration of the drug to be studied in patients with essential hypertension. Evaluate the safety by checking the incidence (%) of adverse events after administration of the drug to be studied in patients with essential hypertension. Evaluate the safety by checking the peripheral edema incidence rate (%) after administration of the drug to be studied in patients with essential hypertension. Evaluate the safety by checking the headache incidence rate (%) after administration of the drug to be studied in patients with essential hypertension.
