Telmisartan Plus S-Amlodipine Single-Pill Combination Therapy is Safe and Effective in Patients with Hypertension from Large-Scale Nationwide Surveillance Data in Korea (NOVEL) Study.

INTRODUCTION

We investigate the safety and efficacy of telmisartan plus S-amlodipine single-pill combination in a real-world population.

METHODS

A total of 44,715 patients who had hypertension and received a telmisartan/S-amlodipine single-pill combination at least once were included for safety and efficacy evaluation from 2852 primary to tertiary hospitals in Korea from August 2013 to December 2019. They were followed up for 3-6 months in terms of safety and efficacy of blood pressure (BP) lowering.

RESULTS

A total of 44,715 patients were included for safety analysis and 41,579 for efficacy analysis. Mean duration of taking the drug was 175.86 ± 48.45 days. A total of 28,096 (62.8%) patients were on telmisartan 40 mg plus S-amlodipine 2.5 mg combination followed by 80/2.5 mg (8664, 19.4%) and 40/5 mg of the drug (7136, 16.0%). Adverse events, total adverse drug reactions, and serious adverse drug reactions were found in 808 patients (1.81%), 352 (0.79%), and 1 (0.002%), respectively. Dizziness and headache were most common (134 [0.30%] and 81 [0.18%]) among all adverse events. Total edema and leg edema were rarely reported, 38 (0.08%) and 25 (0.06%), respectively. Systolic BP (SBP) and diastolic BP (DBP) was lowered from 143.1 ± 16.1/88.1 ± 11.8 mmHg to 129.6 ± 11.4/80.1 ± 9.0 mmHg (difference - 13.5/- 7.9 mmHg, P < 0.0001 for both). Target BP goal attainment rate defined as SBP < 140 mmHg and DBP < 90 mmHg was 74.6% (95% confidence interval [CI] 74.2-75.0) and BP response rate (defined as SBP < 140 mmHg or ≥ 20 mmHg reduction; DBP < 90 mmHg or ≥ 10 mmHg reduction) was 94.5% (95% CI 94.3-94.7).

CONCLUSION

Telmisartan plus S-amlodipine single-pill combination was safe and effective in patients with hypertension in a large real-world population.
