Amlodipine Besylate/Telmisartan

Single risk factors, such as hypertension and dyslipidemia, can combine to exacerbate the development and severity of cardiovascular disease. Treatment goals may be more effectively achieved if multiple disease factors are targeted with combination treatment. We enrolled 202 patients who were randomly divided into the following three groups: telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg, telmisartan 80 mg + rosuvastatin 20 mg, and telmisartan/amlodipine 80/5 mg. The primary efficacy variables were changes from baseline in mean sitting systolic blood pressure (MSSBP) between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg at 8 weeks, and the percent changes from baseline in low‐density lipoprotein (LDL) cholesterol between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg at 8 weeks. The secondary efficacy variables were changes in MSSBP, mean sitting diastolic blood pressure (MSDBP), LDL cholesterol and other lipid levels at 4 weeks and 8 weeks, as well as observed adverse events during follow‐up. There were no significant differences between the three groups in demographic characteristics and no significant difference among the three groups in terms of baseline characteristics for the validity evaluation variables. The mean overall treatment compliance in the three groups was, respectively, 98.42%, 96.68%, and 98.12%, indicating strong compliance for all patients. The Least‐Square (LS) mean (SE) for changes in MSSBP in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg) groups were −19.3 (2.68) mm Hg and −6.69 (2.76) mm Hg. The difference between the two groups was significant (−12.60 (2.77) mm Hg, 95% CI −18.06 to −7.14, P < .0001). The LS Mean for the percent changes from baseline in LDL cholesterol in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg) groups were −52.45 (3.23) % and 2.68 (3.15) %. The difference between the two groups was significant (−55.13 (3.20) %, 95% CI −61.45 to −48.81, P < .0001). There were no adverse events leading to discontinuation or death. Combined administration of telmisartan/amlodipine 80/5 mg and rosuvastatin 20 mg for the treatment of hypertensive patients with dyslipidemia significantly reduces blood pressure and improves lipid control.

Dyslipidemia and hypertension increase the risk for cardiovascular disease. Combination therapy improves patient compliance. This study was conducted to compare the efficacy and tolerability of the combination therapies telmisartan/amlodipine + rosuvastatin, telmisartan/amlodipine, and telmisartan + rosuvastatin in patients with hypercholesterolemia and hypertension.

In this Phase III, multicenter, 8-week randomized, double-blind study, participants with hypertension and dyslipidemia (defined as a sitting systolic blood pressure [sitSBP] of ≥140 mm Hg, a low-density lipoprotein-cholesterol [LDL-C] level of ≤250 mg/dL, and a triglyceride level of ≤400 mg/dL) were screened. After a 4-week washout/run-in period involving therapeutic lifestyle changes and telmisartan 80 mg once a day, eligible patients had a sitSBP of ≥140 mm Hg and met the LDL-C level criteria according to the National Cholesterol Education Program Adult Treatment Panel III cardiovascular disease risk category. Patients were randomly assigned to 1 of 3 groups: (1) telmisartan/amlodipine 80/10 mg + rosuvastatin 20 mg (TAR group); (2) telmisartan/amlodipine 80/10 mg (TA group); or (3) telmisartan 80 mg + rosuvastatin 20 mg (TR group). The primary efficacy end points were the percentage changes from baseline in LDL-C in the TAR and TA groups and the mean changes in sitSBP in the TAR and TR groups at week 8 compared to baseline. Continuous variables were compared using the unpaired t test or the Wilcoxon rank sum model, and categorical variables were compared using the χ² or Fisher exact test. Tolerability was assessed based on adverse events found on physical examination including vital sign measurements, laboratory evaluations, and 12-lead ECG.

A total of 134 patients were enrolled. The least squares mean percentage changes in LDL-C at 8 weeks after administration of the drug compared to baseline were -51.9% (3.0%) in the TAR group and -3.2% (2.9%) in the TA group (P < 0.001). At 8 weeks after baseline, the least squares mean (SE) changes sitSBP were -28.3 (2.4) mm Hg in the TAR group and -10.7 (2.1) mm Hg in the TR group (P < 0.001). The prevalence rates of treatment-emergent adverse events were 15.0%, 25.0%, and 12.2% in the TAR, TA, and TR groups, respectively; those of adverse drug reactions were 15.0%, 22.7%, and 10.2%. None of the differences in rates were significant among 3 groups.

Triple therapy with TAR can be an effective treatment in patients with dyslipidemia and hypertension. The TAR combination has value for hypertensive patients with hyperlipidemia in terms of convenience, tolerability, and efficacy. ClinicalTrials.gov identifier: NCT03566316.
