Abstract
Uncontrolled hypertension is associated with an increased risk of adverse clinical vascular outcomes and death. Hypertension management guidelines from China and the USA recommend initiation of antihypertensive pharmacotherapy with a single drug for patients without severe hypertension at presentation. Current European hypertension guidelines take a different approach and recommend the use of combination therapy from the time of diagnosis of hypertension for most patients. This article reviews the burden of hypertension in these countries and summarises the evidence base for the use of antihypertensive combination therapy contained within a single tablet (single-pill combinations, SPC). Typically, half or less of populations from China, Europe and the USA who were found to have hypertension were aware of their condition, less than half of those receiving treatment, and fewer still achieved adequate blood pressure (BP) control. The reasons for the unaddressed burden of hypertension are complex and multifactorial, with contributions from factors related to patients, healthcare providers and healthcare systems. The use of SPCs of antihypertensive therapies helps to optimise adherence with therapy and is likely to result in superior BP control. There is a strong evidence base to support current European guideline recommendations on the initiation of antihypertensive therapy with SPCs for the majority of people with hypertension.

Abstract
Abstract
Background
To assess the efficacy and safety of a combination therapy involving fimasartan, amlodipine, and rosuvastatin in patients with essential hypertension and dyslipidemia who fail to respond to fimasartan monotherapy.
Methods
This phase III, randomized, double-blind, multicenter study was conducted in adults aged 19–70 years. Patients who voluntarily consented were screened for eligibility to enroll in the study. Patients who failed to respond to 4 weeks of fimasartan monotherapy were randomized with a 1:1:1 ratio to the fimasartan 60 mg/amlodipine 10 mg + rosuvastatin 20 mg (FMS/ALD + RSV) as study group, fimasartan 60 mg/amlodipine 10 mg (FMS/ALD) as control 1 group, and fimasartan 60 mg + rosuvastatin 20 mg (FMS + RSV) as control 2 group. The primary efficacy endpoints were the change in the sitting systolic blood pressure and the rate of change in the low-density lipoprotein cholesterol (LDL-C) level from baseline to 8 weeks. The adverse events, adverse drug reactions, physical examination findings, laboratory test results, electrocardiograms, and vital signs were evaluated to assess safety in the study.
Results
Of 138 randomized patients, 131 were conducted efficacy analysis, and 125 completed the study. For the change in LDL-C and sitting SBP (SiSBP) as primary efficacy assessments, the change in LDL-C at week 8 was significantly reduce in the FMS/ALD + RSV group than in the control 1 group (P < 0.001). The change in SiSBP at week 8 were greater reduce in the FMS/ALD + RSV group than in the FMS + RSV group (both P < 0.001). For the safety evaluation, there were no differences among the treatment groups in the incidence of adverse drug reactions.
Conclusions
The fimasartan/amlodipine + rosuvastatin combination therapy can effectively and safely lower blood pressure and improve lipid levels in patients with essential hypertension and dyslipidemia who fail to respond adequately to fimasartan monotherapy.

Simultaneous Analysis of a Combination of Anti-Hypertensive Drugs, Fimasartan, Amlodipine, and Hydrochlorothiazide, in Rats Using LC-MS/MS and Subsequent Application to Pharmacokinetic Drug Interaction with Red Ginseng Extract. TOXICS 2022; 10:576. [PMID: 36287856 PMCID: PMC9610909 DOI: 10.3390/toxics10100576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 09/27/2022] [Accepted: 09/27/2022] [Indexed: 06/16/2023]
Abstract
Fimasartan, amlodipine, and hydrochlorothiazide are commonly used in combination therapies as antihypertensive drugs. This study aimed to develop and validate an analytical method for fimasartan, its active and major metabolite fimasartan-amide, amlodipine, and hydrochlorothiazide in rat plasma using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The standard calibration curves for fimasartan (1−500 ng/mL), its active and major metabolite fimasartan-amide (0.3−100 ng/mL), amlodipine (0.5−200 ng/mL), and hydrochlorothiazide (5−5000 ng/mL) were linear with R2 > 0.9964, and the inter- and intra-day accuracy and precision and stability were within the acceptable criteria. Using this validated analytical method, the pharmacokinetic interaction of these triple combination drugs between single administration and concomitant administration of the triple combination was investigated; the results did not reveal a significant difference in any of the pharmacokinetic parameters. Based on these results, we investigated the effects of red ginseng extract (RGE) on the pharmacokinetics of fimasartan, fimasartan-amide, amlodipine, and hydrochlorothiazide after oral administration of the combination in rats. No significant difference was observed in the pharmacokinetic parameters of fimasartan, fimasartan-amide, amlodipine, and hydrochlorothiazide, except for the Tmax values of amlodipine. The delayed Tmax value of amlodipine was attributed to its decreased intestinal permeability after repeated RGE treatments. In conclusion, using a combination of antihypertensive drugs and simultaneous analytical methods, we established efficient drug interaction and toxicokinetic studies using a small number of animals.

Abstract
OBJECTIVE To evaluate the efficacy of combination of angiotensin receptor blocker (ARB) with hydrochlorothiazide (HCTZ) compared to ARB alone in patients with uncontrolled hypertension via a systematic review and meta-analysis. METHODS We searched databases till July 2019 using relevant search terms. We included articles that were randomised controlled trials (RCTs) comparing ARB/HCTZ with ARB for a duration of at least 4 weeks and reported on the efficacy or safety. Meta-analyses for efficacy outcomes were performed. In addition, groups given different concentrations of HCTZ (12.5 and 25 mg) were analysed separately. RESULTS Sixteen RCTs (12,055 participants) were included. Overall, ARB/HCTZ combination therapy (both 12.5 and 25 mg HCTZ combination) resulted in better sitting systolic and diastolic blood pressure control than ARB alone (mean difference (95% confidence interval (CI): -5.69 [-6.66, -4.73] for 12.5 mg and -9.10 [-11.78, -6.42] for 25 mg and mean difference (95% CI): -2.91 [-3.31, -2.51] for 12.5 mg and -4.16 [-4.75, -3.58] for 25 mg). ARB/HCTZ combination therapy resulted in a higher rate of target blood pressure achievement compared to ARB alone (risk ratio (95% CI): 1.50 [1.42, 1.59]). ARB/HCTZ combination therapy had similar rates of total adverse events (AEs) and severe AEs compared to ARB alone. CONCLUSION ARB/HCTZ combination therapy is more efficacious for controlling blood pressure, and combination with a low concentration of HCTZ has similar AEs compared to ARB alone. Clinicians should consider adding HCTZ in the medication regime of patients with uncontrolled hypertension using ARB, if their clinical profile allows.

Combining angiotensin receptor blockers with chlorthalidone or hydrochlorothiazide - which is the better alternative? A meta-analysis. Syst Rev 2020; 9:195. [PMID: 32838806 PMCID: PMC7445912 DOI: 10.1186/s13643-020-01457-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 08/14/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Hypertension is a disease with significant clinical and socio-economic consequences. The reduction in cardiovascular mortality and morbidity in patients treated for hypertension is directly related to the magnitude of blood pressure reduction. Diuretics have proven useful for the prevention of cardiovascular complications in addition to a long history of safety and efficacy. The main aim for this meta-analysis is to compare the efficacy of the combination of angiotensin receptor blocker (ARB) and chlorthalidone (CTLD) to the combination of ARB and hydrochlorothiazide (HCTZ) in patients with hypertension. METHODS A comprehensive literature search was conducted through electronic databases PubMed, MEDLINE, Scopus, PsyInfo, Cochrane, eLIBRARY.ru, http://ClinicalTrials.gov and http://www.clinicaltrialsregister.eu in July 2020 to identify studies that investigate the effect of the combination of angiotensin receptor blocker with chlorthalidone or hydrochlorothiazide on the systolic and diastolic blood pressure in patients with hypertension. Changes in systolic and diastolic blood pressure (BP) expressed as a weighted mean difference (WMD) were our primary outcomes. The random-effects method was chosen as the primary analysis and results were presented with a 95% confidence interval (CI). Sensitivity analysis was performed and bias was assessed. RESULTS Our search returned 2745 titles. Of them, 51 full-text articles remained to be subjected to assessment. Comparisons of ARB/HCTZ versus ARB showed changes in BP of -6.89 (-8.09, -5.69) mmHg for systolic BP and - 3.67 (-4.15, -3.19) mmHg for diastolic BP. For the ARB/CTLD versus ARB/HCTZ comparison changes were - 6.30 (-7.30, -5.29) mmHg for systolic BP and - 3.57 (-4.17, 2.98) mmHg for diastolic BP. CONCLUSION Our analysis suggests a small but significant favor for CTLD in blood pressure control when compared to HCTZ. We believe it should be considered as a valuable alternative for HCTZ and an option for fixed dose combinations with an ARB although further research is required.

Abstract
INTRODUCTION Fimasartan is the ninth and latest Angiotensin Receptor Blockers for the treatment of hypertension. Fimasartan is a derivative of losartan in which the imidazole ring has been replaced. It provides a selective type 1 angiotensin II receptor antagonist effect with noncompetitive, in surmountable binding. Fimasartan is rapidly absorbed following oral administration with an oral bioavailability of 18.6 ± 7.2%. Fimasartan is relatively stable in terms of metabolism and more than 90% of circulating fimasartan moieties in the plasma are in the parent form; fecal elimination and biliary excretion are the predominant elimination pathways of fimasartan. Areas covered: We reviewed data from clinical trials that investigated safety and efficacy of fimasartan in hypertension. Expert opinion: Fimasartan proved good efficacy in blood pressure reduction. In large clinical studies,fimasartan showed an excellent safety profile and when combined with hydrochlorothiazide oram lodipine, it showed a better effect on controlling blood pressure than monotherapy. Fimasartan 60-120 mg once daily has also shown an antihypertensive effect over 24-h. Moreover, preclinical studies demonstrated organ-protecting effects of fimasartan. These results make fimasartan an attractive candidate for the treatment of hypertension. However, it remains to test the benefit of using fimasartan on clinical outcomes.

Abstract
BACKGROUND/AIMS Fimasartan is an angiotensin type 1 receptor blocker (ARB) which has comparable efficacy and tolerability with other ARBs. The aim of this study was to evaluate 24-hour blood pressure (BP) lowering efficacy and the tolerability of the low dose fimasartan compared with valsartan in patients with mild to moderate hypertension. METHODS This study was a phase II, prospective, multicenter, randomized, double-blind, parallel-grouped trial. A total of 75 hypertensive patients, whose mean ambulatory BP monitoring values were ≥ 135/85 mmHg, were randomized to either fimasartan 30 mg or valsartan 80 mg daily. The primary efficacy endpoint was the change in the mean 24-hour systolic BP (SBP) values from the baseline and at the week 8. Secondary endpoints included the change in the mean 24-hour diastolic BP values, the daytime and the nighttime mean BP values at week 8, the trough-to-peak (T/P) ratio and the smoothness index. RESULTS At week 8, the mean 24-hour SBP values significantly decreased in both groups; -10.5 ± 11.9 mmHg (p < 0.0001) in the fimasartan group and -5.5 ± 11.6 mmHg (p = 0.0307) in the valsartan group. The difference between two groups was 4.3 ± 2.9 mmHg but there was no statistical significance (p = 0.1392). The global T/P ratio in the fimasartan 30 mg groups were 0.48 and 0.40 in the valsartan 80 mg group, respectively (p = 0.3411). The most frequent adverse events (AEs) were acute pharyngitis and there were no cases of severe AEs. CONCLUSIONS In mild-to-moderate hypertensive patients, low dose (30 mg) fimasartan showed comparable 24-hour BP lowering efficacy compared with valsartan (80 mg). There was no difference in tolerability between two groups.

Abstract
Background Hypertension and dyslipidemia are major risk factors of cardiovascular disease (CVD) events. The objective of this study was to evaluate the efficacy and safety of the co-administration of fimasartan and rosuvastatin in patients with hypertension and hypercholesterolemia. Methods We conducted a randomized double-blind and parallel-group trial. Patients who met eligible criteria after 4 weeks of therapeutic life change were randomly assigned to the following groups. 1) co-administration of fimasartan 120 mg/rosuvastatin 20 mg (FMS/RSV), 2) fimasartan 120 mg (FMS) alone 3) rosuvastatin 20 mg (RSV) alone. Drugs were administered once daily for 8 weeks. Results Of 140 randomized patients, 135 for whom efficacy data were available were analyzed. After 8 weeks of treatment, the FMS/RSV treatment group showed greater reductions in sitting systolic (siSBP) and diastolic (siDBP) blood pressures than those in the group receiving RSV alone (both p < 0.001). Reductions in siSBP and siDBP were not significantly different between the FMS/RSV and FMS alone groups (p = 0.500 and p = 0.734, respectively). After 8 weeks of treatment, FMS/RSV treatment showed greater efficacy in percentage reduction of low-density lipoprotein cholesterol (LDL-C) level from baseline than that shown by FMS alone treatment (p < 0.001). The response rates of siSBP with FMS/RSV, FMS alone, and RSV alone treatments were 65.22, 55.56, and 34.09%, respectively (FMS/RSV vs. RSV, p = 0.006). The LDL-C goal attainment rates with FMS/RSV, RSV alone, and FMS alone treatments were 80.43%, 81.82%, and 15.56%, respectively (FMS/RSV vs. FMS, p < 0.001). Incidence of adverse drug reactions with FMS/RSV treatment was 8.33%, which was similar to those associated with FMS and RSV alone treatments. Conclusion This study demonstrated that the co-administration of fimasartan and rosuvastatin to patients with both hypertension and hypercholesterolemia was efficacious and safe.

Abstract
Fimasartan is the ninth, and most recent, angiotensin II receptor antagonist approved as an antihypertensive agent. Fimasartan, a pyrimidin-4(3H)-one derivative of losartan with the imidazole ring replaced, which enables higher potency and longer duration than losartan. Fecal elimination and biliary excretion are the predominant elimination pathways of fimasartan and the urinary excretion was found to be less than 3 % 24 h after administration. Fimasartan is primarily catabolized by cytochrome P450 isoform 3A and no significant drug interaction was observed when used in combination with hydrochlorothiazide, amlodipine, warfarin, or digoxin. Fimasartan at a dosage range of 60-120 mg once daily showed an antihypertensive effect over 24 h. In a large, population-based observational study, fimasartan showed an excellent safety profile. Anti-inflammatory and organ-protecting effects of fimasartan have been shown in various preclinical studies, including aortic balloon injury, myocardial infarct ischemia/reperfusion, doxorubicin cardiotoxicity, and ischemic stroke models.
