[PMID: 39022172 PMCID: PMC11250860 DOI: 10.1016/j.cjco.2024.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 03/03/2024] [Indexed: 07/20/2024] Open
Abstract
Background Hypertension Canada 2017 guidelines favoured the use of thiazide (TZ)-like diuretics, such as CLTD (chlorthalidone) and indapamide (IND) over hydrochlorothiazide (HCTZ). Health Canada warned in 2019 that HCTZ may be associated with increased risk of skin cancer. Our study looked at the changes in TZ prescriptions from 2015 to 2021 in Ontario, Canada. Methods A retrospective cohort study was conducted of adults with hypertension, using electronic medical record data from the University of Toronto Practice-Based Research Network database covering mostly the Greater Toronto area. Outcomes included the proportion of patients who received a prescription of HCTZ, CLTD, or IND each month. Interrupted time-series analysis was used to evaluate the change in outcomes after publication of the 2017 guidelines and 2019 safety warning. Prescription trends were stratified by prescribing physicians' sex and year of medical school graduation. Results A total of 100,428 patients with hypertension were included in the cohort, with 31,700 patients who received at least one TZ prescription from 343 family physicians. We found a declining trend in HCTZ prescriptions over time, accompanied by an increase in IND and CLTD prescriptions, with statistically significant but transient changes in prescription rates after publication of the 2017 guidelines and the 2019 safety warning for all 3 medications. Female physician and early-career physician prescription rates changed faster than that of their counterparts immediately after the Health Canada safety warning was issued. Conclusions TZ diuretic prescription patterns have changed in recent years, but Hypertension Canada's 2017 guidelines and the 2019 Health Canada safety warning did not have a sustained significant impact on the change in prescription rates of HCTZ, IND, and CLTD.

Abstract
To celebrate 100 years of American Heart Association-supported cardiovascular disease research, this review article highlights milestone papers that have significantly contributed to the current understanding of the signaling mechanisms driving hypertension and associated cardiovascular disorders. This article also includes a few of the future research directions arising from these critical findings. To accomplish this important mission, 4 principal investigators gathered their efforts to cover distinct yet intricately related areas of signaling mechanisms pertaining to the pathogenesis of hypertension. The renin-angiotensin system, canonical and novel contractile and vasodilatory pathways in the resistance vasculature, vascular smooth muscle regulation by membrane channels, and noncanonical regulation of blood pressure and vascular function will be described and discussed as major subjects.

Exploratory study on the relationship between urinary sodium/potassium ratio, salt intake, and the antihypertensive effect of esaxerenone: the ENaK Study. Hypertens Res 2024; 47:835-848. [PMID: 38212366 PMCID: PMC10994843 DOI: 10.1038/s41440-023-01519-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 10/30/2023] [Accepted: 11/05/2023] [Indexed: 01/13/2024]
Abstract
Excessive salt intake is one of the causes of hypertension, and reducing salt intake is important for managing the risk of hypertension and subsequent cardiovascular events. Esaxerenone, a mineralocorticoid receptor blocker, has the potential to exert an antihypertensive effect in hypertensive patients with excessive salt intake, but evidence is still lacking, especially in clinical settings. We aimed to determine if baseline sodium/potassium ratio and baseline estimated 24-h urinary sodium excretion can predict the antihypertensive effect of esaxerenone in patients with essential hypertension inadequately controlled with an angiotensin receptor blocker (ARB) or a calcium channel blocker (CCB). This was an exploratory, open-label, interventional study with a 4-week observation period and a 12-week treatment period. Esaxerenone was orally administered once daily in accordance with the Japanese package insert. In total, 126 patients met the eligibility criteria and were enrolled (ARB subcohort, 67; CCB subcohort, 59); all were included in the full analysis set (FAS) and safety analysis. In the FAS, morning home systolic blood pressure (SBP)/diastolic blood pressure (DBP) significantly decreased from baseline to end of treatment (primary efficacy endpoint) (-11.9 ± 10.9/ - 6.4 ± 6.8 mmHg, both p < 0.001); a similar trend was observed in both subcohorts. Significant reductions were also shown in bedtime home and office SBP/DBP (all p < 0.001). Each BP change was consistent regardless of the urinary sodium/potassium ratio or estimated 24-h urinary sodium excretion at baseline. The urinary albumin-creatinine ratio (UACR) and N-terminal pro-brain natriuretic peptide (NT-proBNP) significantly decreased from baseline to Week 12 in the total population and both subcohorts. No new safety concerns were raised. Esaxerenone significantly decreased morning home, bedtime home, and office BP; UACR; and NT-proBNP in this patient population, regardless of concomitant ARB or CCB use. The antihypertensive effect of esaxerenone was independent of the urinary sodium/potassium ratio and estimated 24-h urinary sodium excretion at baseline.

Abstract
This article reviews available evidence regarding hypertension management in the Asia-Pacific region, focussing on five research questions that deal with specific aspects: blood pressure (BP) control, guideline recommendations, role of renin-angiotensin-aldosterone system (RAAS) inhibitors in clinical practice, pharmacological management and real-world adherence to guideline recommendations. A PubMed search identified 2537 articles, of which 94 were considered relevant. Compared with Europeans, Asians have higher systolic/diastolic/mean arterial BP, with a stronger association between BP and stroke. Calcium channel blockers are the most-commonly prescribed monotherapy in Asia, with significant variability between countries in the rates of angiotensin-converting enzyme inhibitors (ACEis)/angiotensin-receptor blockers (ARBs) and single-pill combination (SPC) use. In clinical practice, ARBs are used more commonly than ACEis, despite the absence of recommendation from guidelines and clinical evidence supporting the use of one class of drug over the other. Ideally, antihypertensive treatment should be tailored to the individual patient, but currently there are limited data on the characteristics of hypertension in Asia-Pacific individuals. Large outcome studies assessing RAAS inhibitor efficacy and safety in multi-national Asian populations are lacking. Among treated patients, BP control rates were ~ 35 to 40%; BP control in Asia-Pacific is suboptimal, and disproportionately so compared with Western nations. Strategies to improve the management of hypertension include wider access/availability of affordable treatments, particularly SPCs (which improve adherence), effective public health screening programs targeting patients to drive health-seeking behaviours, an increase in physician/patient awareness and early implementation of lifestyle changes. A unified Asia-Pacific guideline on hypertension management with pragmatic recommendations, particularly in resource-limited settings, is essential.

EXPLORATORY RESEARCH IN CLINICAL AND SOCIAL PHARMACY 2023; 11:100315. [PMID: 37635839 PMCID: PMC10448163 DOI: 10.1016/j.rcsop.2023.100315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/29/2023] Open
Abstract
Background Hypertension has affected over 1.13 billion people worldwide in 2015 and it's one of the most preventable risk-factors for morbidity and mortality. Antihypertensives significantly reduce cardiovascular risks. Several studies on antihypertensives' prescribing patterns were conducted worldwide, and guidelines were developed on hypertension management. However, no systematic reviews were conducted globally to synthesize the evidence from these studies. This review aims to evaluate antihypertensives' prescription patterns, and adherence to international guidelines for hypertension management worldwide. Methods Full-text antihypertensives' prescribing patterns evaluation studies were included. Reviews, commentaries, guidelines, and editorials were excluded. Various databases were searched including PubMed, Embase, and others. Studies were limited to English only and to articles published from (01/01/2010) to (20/03/2020). Crowe Critical Appraisal Tool (CCAT) was used for quality assessment. Results The most commonly prescribed antihypertensives as monotherapy in adult patients with no comorbidities were ACEIs/ARBs (Angiotensin converting enzyme inhibitors/Angiotensin receptor blockers), followed by CCBs (Calcium channel blockers), and BBs (Beta Blockers). Most commonly prescribed dual combinations were thiazide diuretics+ACEIs/ARBs, BBs + CCBs and CCBs+ACEIs/ARBs. Among diabetic patients, the most common agents were ACEIs/ARBs. Among patients with heart diseases, CCBs were prescribed frequently. While patients with kidney diseases, CCBs and ARBs were most prescribed. Of the 40 studies included in the review, only four studies directly assessed the prescribing patterns of antihypertensives in adherence to clinical practice guidelines. And only two studies confirmed adherence to guidelines. Furthermore, the quality of the majority of studies was moderate (50%), while 25% of articles were reported as either high or low quality. Conclusion This review revealed that there are areas for improvement for prescribing practices of antihypertensives in concordance with the latest evidence and with clinical practice guidelines.

Abstract
Background Hydrochlorothiazide (HCT), a widely used hypertensive drug, has photocarcinogenic potential, leading to concerns about the development of nonmelanoma skin cancers (SCs) after intake. Despite substantial numbers of observational studies, the results remain inconsistent especially among Asian countries. Objective To assess the incidence of nonmelanoma SCs in hypertensive Japanese HCT users compared with nonusers. Methods A population-based, cohort nested, propensity score-matched study was conducted using the Shizuoka Kokuho database. All participants were patients aged ≥60 years. Hazard ratios for SC incidence were calculated in the matched cohorts using the propensity scores of potential confounders, sex, age category, comorbidities, and administration of methotrexate, cyclosporin, and statins. Results The risk of SC was higher in HCT users than in nonusers (hazard ratio, 1.58; 95% confidence interval, 1.04-2.40), with preferential sun-exposed location and a tendency to develop squamous cell carcinoma, but not basal cell carcinoma or Bowen disease. Limitations No additional information was available from other than medical records. The data were confined to a Japanese population. Conclusion HCT use increases the risk of SC in Japanese patients with hypertension and a dark skin type, highlighting the increased risk of SC among HCT users in the aging society worldwide.

J Clin Hypertens (Greenwich) 2023; 25:861-867. [PMID: 37551054 PMCID: PMC10497029 DOI: 10.1111/jch.14705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 07/19/2023] [Accepted: 07/20/2023] [Indexed: 08/09/2023]
Abstract
The next-generation mineralocorticoid receptor blocker (MRB) esaxerenone has favorable antihypertensive effects in patients who do not respond to treatment with first-line antihypertensive agents and may be beneficial as a second-line treatment. However, MRBs are currently considered a fourth-line treatment as there is no clinical evidence comparing the efficacy of esaxerenone with other classes of antihypertensive agents. The multicenter, randomized, open-label, parallel-group EXCITE-HT study will evaluate the efficacy and safety of esaxerenone as a second-line agent in the treatment of Japanese patients with uncontrolled essential hypertension. After a 4-week run-in period, patients will receive either esaxerenone or trichlormethiazide for 12 weeks per the package insert and the Japanese Society of Hypertension Guidelines for the Management of Hypertension. At Weeks 4 and 8, the dose of esaxerenone or trichlormethiazide may be increased. Blood pressure (home [morning and bedtime] and office), serum biomarkers, and urinary biomarkers will be measured. The primary efficacy endpoint is the change from baseline in morning home systolic blood pressure/diastolic blood pressure to the end of treatment. The EXCITE-HT study is expected to validate the non-inferiority of esaxerenone to trichlormethiazide and provide the first evidence for the early use of esaxerenone as a second-line agent in the treatment of Japanese patients with uncontrolled essential hypertension instead of its current use as a fourth-line agent.

Abstract
A prospective cross-sectional study was conducted to analyse the drugs prescribed to the elderly population with noncommunicable diseases and to determine the polypharmacy at a primary care clinic in Negeri Sembilan, Malaysia. The study was conducted for 6 months at the primary care clinic of Gemas. Geriatric patients above the age of 65 and diagnosed with noncommunicable diseases were included upon providing written informed consent. The majority of the geriatric patients were between 65 and 69 years (mean: 69.72 ± 2.85) and prescribed 4 or more medications (mean: 5.18 ± 0.64, p = 0.007). More than 95% (n = 295) of the geriatrics were found to have multimorbidity, in which around 45% (n = 139) had type-2 diabetes together with hypertension and dyslipidaemia. Combination therapy was prescribed to more than 97% (n = 302) of the elderly, whereas cardiovascular and endocrine medications were the most commonly prescribed. Ten prescriptions were found to have drug-related problems, prescribing cascade (80%), lack of medicine optimisation (10%), and inappropriate prescription (10%). In this study, the majority of the elderly had multimorbidity; polypharmacy was commonly seen among geriatric patients. Polypharmacy is the biggest threat to the elderly population, as it increases the chances of falls and fall-related injuries. Medicine optimisation and deprescribing will reduce the chances of drug-related problems and morbidity and mortality associated with polypharmacy and over-consumption of medications. Hence, the study recommends the health fraternity look for medication optimisation and deprescribing to reduce the future complications associated with polypharmacy.

Antihypertensive Effect of Long-Term Monotherapy with Esaxerenone in Patients with Essential Hypertension: Relationship Between Baseline Urinary Sodium Excretion and Its Antihypertensive Effect. Adv Ther 2022; 39:4779-4791. [PMID: 35976603 PMCID: PMC9464726 DOI: 10.1007/s12325-022-02282-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 07/22/2022] [Indexed: 01/30/2023]
Abstract
INTRODUCTION The blood pressure (BP) control mechanism for mineralocorticoid receptor blockers is unclear, and analysis of their use as a single agent in the clinical setting is required to resolve this uncertainty. There is a paucity of data on esaxerenone monotherapy assessing its long-term antihypertensive effect and urinary biomarkers. METHODS This post hoc exploratory substudy of a long-term phase 3 study evaluated the effect of esaxerenone monotherapy (2.5 or 5 mg/day) in treatment-naïve patients who continued the therapy during the 52-week study period (n = 25). In addition to blood biomarkers, urinary biomarkers were also assessed in 24-h urine collection samples. RESULTS Esaxerenone monotherapy was associated with consistent reductions in systolic/diastolic BP in the substudy population (- 23.5/- 13.1 mmHg at week 52, p < 0.001 vs baseline). Plasma aldosterone concentrations and plasma renin activity significantly increased during esaxerenone monotherapy at all time points. On the basis of the observations that both urine volume and urinary sodium excretion also decreased up to the end of the study, and were significantly lower at 12 weeks, patients were further categorized into higher/lower urinary sodium excretion subgroups according to whether their baseline values were above or below the median. In the group with higher baseline urinary sodium excretion, esaxerenone exhibited a significantly greater decrease in systolic/diastolic BP compared to the lower baseline group. CONCLUSION Esaxerenone exhibited sustained and stable antihypertensive activity even when administered as a single agent for 52 weeks in patients with essential hypertension. The additional urinary biomarker analysis suggests that the BP-lowering effects of esaxerenone may be partly exerted via mechanisms related to salt and water retention, and that the effect is particularly pronounced in patients with hypertension and higher baseline urinary sodium excretion, which may reflect a state of excessive salt intake.

Abstract
High salt intake has been shown to induce hypertrophy and fibrosis in the atria and ventricles, which could result in the development of atrial fibrillation (AF). Whereas the development of AF is suggested to be prevented by renin-angiotensin system (RAS) inhibitors, recent findings have indicated that this prevention is closely associated with their antihypertensive effects. In this study, we investigated whether the L/N-type Ca2+ channel blocker cilnidipine counteracts salt-induced atrial and ventricular remodelling and the inducibility of AF. Cilnidipine was orally administered to Dahl salt-sensitive rats fed with an 8% NaCl diet at 10 mg/kg for 5 weeks, and then electrophysiological evaluation and histological analyses were performed. The effects were compared with those of the L-type Ca2+ channel blocker amlodipine at 3 mg/kg. Following the intake of the 8% NaCl diet, the blood pressure (BP) increased, and fibrosis was induced in the atria and ventricles. Cilnidipine decreased BP, and the extent of the decrease in the cilnidipine group was similar to those in the amlodipine group. Cilnidipine produced a greater decrease in the fibrotic area in the atria and ventricles than amlodipine. The cilnidipine group shortened the AF duration from 7.43 ± 3.16 to 2.95 ± 1.73 s, which had been increased by NaCl intake. Plasma noradrenaline levels in the cilnidipine group were lower than those in the amlodipine group. Thus, the suppressive effects of cilnidipine on the salt-induced atrial and ventricular remodelling, fibrosis, and AF sustainability might be closely associated with its N-type Ca2+ channel-blocking actions.

Background: Angiotensin II receptor blockers (ARBs) are widely used for the management of hypertension in Japan; however, comparative efficacy data within the ARB drug class remain limited. Methods and Results: This systematic literature review identified randomized controlled trials (RCT) indexed in PubMed and Ichushi in Japanese patients with hypertension receiving ARB monotherapy (azilsartan, candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, valsartan) in at least 1 arm. Of 763 RCTs identified, 77 met the eligibility criteria; of which, 37 reported mean change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) from baseline in the office setting and were used to construct the network. A fixed-effects model (FEM) showed the effect of each drug vs. the reference, azilsartan. Using the FEM, the mean (95% credible interval) change from baseline in SBP/DBP for candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, and valsartan was 3.8 (2.9-4.8)/2.6 (2.0-3.1), 4.8 (2.0-7.5)/3.7 (1.8-5.6), 3.0 (0.8-5.1)/1.9 (0.5-3.3), 3.2 (1.2-5.1)/2.7 (1.3-4.1), 3.2 (0.8-5.6)/2.0 (0.3-3.6), and 3.1 (1.1-5.1)/2.4 (1.1-3.8) mmHg, respectively. Conclusions: The results of this meta-analysis provide evidence that azilsartan has a more favorable efficacy profile than the other ARBs in reducing SBP and DBP.

Treatment patterns of antihypertensive fixed‐dose combinations according to age and number of agents prescribed: Retrospective analysis using a Japanese claims database.

Abstract
Aim To determine the real‐world use of fixed‐dose combinations (FDC) of antihypertensive agents using data collected from a nationwide medical database of acute hospitals in Japan. Methods We carried out a retrospective analysis of data from the Medical Data Vision database for patients with hypertension who received an antihypertensive drug prescription between April 2014 and March 2015. The prescription rate of antihypertensive FDC were assessed by class, age and according to combinations. Results In total, data from 59 867 patients aged 70.0 ± 11.9 years (mean ± SD) were analyzed. Patients were prescribed 1.9 ± 1.0 oral antihypertensive agents (mean ± SD). Overall, 58.6% of patients were prescribed two or more antihypertensive agents, and the most frequently prescribed classes were calcium channel blockers (CCB) and angiotensin II receptor blockers (ARB). As the number of concomitant antihypertensive agents prescribed increased, the prescription rate of a CCB + an ARB FDC decreased, whereas the prescription rate of an ARB + a diuretic FDC increased. This trend was the same regardless of age. Of the 12 222 patients who were prescribed a CCB + an ARB, 26.0% received a FDC. In contrast, of the 922 patients prescribed an ARB + a thiazide diuretic, 80.6% received a FDC. Medium doses of both CCB and ARB agents, and low doses of diuretics were the most frequently prescribed for each class. Conclusions Our analyses show that the real‐world use of FDC varies depending on the combination of agent class and the number of prescriptions; the latter was similar regardless of age.

Abstract
Hypertension requires strict treatment because it causes diseases that can lead to death. Although various classes of antihypertensive drugs are available, the actual status of antihypertensive drug selection and the transition in prescription patterns over time have not been fully examined. Therefore, we conducted a claims-based study using two claims databases (2008–16) to determine this status in Japan. We examined the prescription rate for each class of antihypertensive drugs in hypertensive patients and compared the patients’ ages and the sizes of the medical institutions treating these patients. Among the 1 560 865 and 302 433 hypertensive patients in each database, calcium channel blockers (CCBs) (>60%) and angiotensin II receptor blockers (ARBs) (>55%) were the most frequently prescribed classes. The prescription rate of CCBs increased and ARBs decreased with the patients’ ages. Although the Japanese guidelines for management of hypertension in 2014 changed the recommendation and indicated that β-blockers should not be used as first-line drugs, their prescription status did not change during this study period up to 2016. Use of CCBs and ARBs as first-line drugs differed by the types of patient comorbidities. Although ARBs or angiotensin-converting enzyme inhibitors were recommended for patients with some comorbidities, CCBs were used relatively frequently. In conclusion, the patients’ ages and comorbidities and the sizes of the medical institutions affect the selection of antihypertensive drugs. Selection and use of drugs may not always follow the guidelines.

Abstract
In 2014, the Japanese Society of Hypertension (JSH) issued revised guidelines for hypertension management. To assess adherence to the guidelines, this retrospective study evaluated the real-world status of antihypertensive drug prescribing for Japanese patients with hypertension, classified by comorbidity: diabetes mellitus, dyslipidemia, gout/hyperuricemia and renal diseases. Data on 59,867 hypertensive patients who received their first prescription for antihypertensive therapy between April 2014 and March 2015, were obtained from a medical insurance claims database for hospitals participating in the Diagnosis Procedure Combination/Per-Diem payment system. The most common drugs prescribed for each comorbidity subgroup were calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs), with prescription rates of around 60-70%. Contrary to JSH recommendations, diuretics and angiotensin-converting enzyme inhibitors were prescribed less often than β-blockers. Whereas diabetes mellitus is a compelling indication for use of renin-angiotensin system inhibitors, CCBs were commonly prescribed in this subgroup. The treatment pattern for patients with comorbid dyslipidemia closely resembled that for the overall patient population. Loop diuretics were prescribed more frequently for patients with renal diseases or gout/hyperuricemia than for those with diabetes mellitus or dyslipidemia. Although antihypertensive drug prescribing varied by comorbidity, JSH 2014 guidelines appeared not to be incorporated adequately into actual clinical practice.

Mechanism of the blood pressure-lowering effect of sodium-glucose cotransporter 2 inhibitors in obese patients with type 2 diabetes. BMC Pharmacol Toxicol 2017; 18:23.

Abstract
Background Sodium-glucose cotransporter 2 (SGLT2) inhibitors are reported to have BP-lowering effect in addition to blood glucose-lowering effect, however, its mechanism is still unknown. This study aimed to investigate the mechanism of blood pressure (BP) lowering effects of SGLT2 inhibitors using 24-h urinary collection in obese type 2 diabetes patients. Methods Twenty patients with type 2 diabetes (age 48.2 ± 10.7 years, BMI 33.0 ± 4.9 kg/m2) were enrolled. Urine volume, 24-h urinary glucose and sodium excretion, and BP at baseline and 2 weeks and 6 months after administration were measured. Body weight, glycosylated hemoglobin, and BP were evaluated before and 1, 3, and 6 months after SGLT2 inhibitor administration. We evaluated the changes in urine volume and urinary excretion of glucose and sodium as well as correlations among urine volume and urinary sodium glucose excretion at 2 weeks and 6 months after administration of the SGLT2 inhibitors. Furthermore, we investigated the correlations between changes in BP and urinary excretion of sodium and glucose at the same time. Results Two weeks after administration, systolic BP (SBP) significantly decreased (128.5 ± 11.0 to 123.2 ± 9.8 mmHg, P = 0.0314), but diastolic BP (DBP) did not (74.4 ± 10.4 to 73.4 ± 8.5 mmHg, P = 0.5821). The decreased SBP significantly correlated with increased urinary glucose excretion (R = −0.62, P = 0.0073), but not increased urinary sodium excretion. At 6 months, SBP (118.6 ± 11.0 mmHg, P = 0.0041) and DBP (68.4 mmHg, P = 0.0363) significantly decreased. The decreased SBP significantly correlated with increased urinary sodium excretion (R = −0.60, P = 0.0014), but not increased urinary glucose excretion. Conclusions SGLT2 inhibitors significantly decreased SBP after 1 month and DBP after 6 months in obese patients with type 2 diabetes. The main mechanism of the BP-lowering effect may be plasma volume reduction by osmotic diuresis at 2 weeks and by natriuresis at 6 months after SGLT2 inhibitor administration.
