    Abstract:
    BACKGROUND: The efficacy and safety of a single-pill combination (SPC) of olmesartan/amlodipine/hydrochlorothiazide (OLM/AML/HCTZ) have been established previously through multiple studies. However, the real-world data in Korean patients are still limited. This study evaluated the effectiveness and safety of SPC of OLM/AML/HCTZ in a real practice setting in Korean patients with essential hypertension. METHODS: This was an observational, retrospective, multi-center, non-comparative cohort study. Medical records of 9749 patients with essential hypertension who had been prescribed OLM/AML/HCTZ within 1 year of the study were analyzed. The primary outcome was the achievement rate (%) of the target blood pressure goal of a systolic blood pressure (SBP) of < 140 mmHg and a diastolic blood pressure (DBP) of < 90 mmHg following administration of OLM/AML/HCTZ. The secondary outcomes included the rate of BP control measured at each visit, the amount of BP reduction compared to the index date, and the prescribing patterns of OLM/AML/HCTZ. Safety and tolerability were assessed by the incidence rate of adverse events (AEs) and discontinuation. RESULTS: In the effectiveness analysis set (n = 9604), the overall achievement rate of target BP was 82.56%. The mean SBP/DBP was significantly reduced compared to baseline at all visits (all p < 0.0001), with the greatest reduction occurring at week 2. The achievement rate of target BP was above 71%, regardless of the presence of risk factors (diabetes mellitus, DM; cardiovascular disease, CVD; chronic kidney disease, CKD). Patients with CVD and aged > 65 years showed a significantly higher achievement rate (p < 0.05). A significant relationship existed between the primary outcome and age (p < 0.0001). The achievement rate exceeded 74% in all different age groups. In the safety analysis set (n = 9661), AEs were reported in 8.46% of patients, with the most frequent AE being dizziness. Serious adverse events (SAEs) and unexpected adverse events (UAEs) occurred in 0.96% and 3.73% patients, respectively. This was consistent with the previously reported safety profile of OLM/AML/HCTZ. The majority of AEs were mild to moderate and resolved during the observation period. The discontinuation rate of OLM/AML/HCTZ due to AEs was 1.67%. CONCLUSION: This study demonstrated significant effectiveness of OLM/AML/HCTZ in achieving target BP in Korean patients with essential hypertension. OLM/AML/HCTZ was well tolerated.
