Abstract
INTRODUCTION Arterial hypertension represents the leading modifiable risk factor for all-cause death and early development of cardiovascular disease in women. Current clinical guidelines for the treatment of hypertension noted that women respond to antihypertensive drugs similarly to men and, therefore, treatment recommendations remain the same for both sexes. However, clinical evidence suggests the existence of sex- and gender-related differences (SGRD) in the prevalence, pathophysiology, pharmacodynamics (efficacy and safety) and pharmacokinetics of antihypertensive drugs. AREAS COVERED This review summarizes SGRD in the prevalence of hypertension, hypertension-mediated organ damage and blood pressure control, prescription patterns, and pharmacokinetics/ pharmacodynamics and doses of antihypertensive drugs. EXPERT OPINION There is limited information on SGRD in antihypertensive drug efficacy because of the underrepresentation of women in randomized clinical trials and, more important, because few trials reported results stratified by sex or performed sex-specific analyses. However, there are SGRD in hypertension-mediated organ damage, drug pharmacokinetics and, particularly, in drug safety. Prospective trials specifically designed to better understand the basis for SGRD in the pathophysiology of hypertension and in the efficacy and safety of antihypertensive drugs are needed to achieve a more personalized treatment of hypertension and hypertension-mediated organ damage in women.

Abstract
OBJECTIVE Several factors affect adherence to antihypertensive drug treatment, but whether these factors include a sex difference is unclear. Aim of the study was to compare persistence with antihypertensive drug therapy between men and women in a large cohort of patients. METHODS The 60 526 residents of the Italian Lombardy Region aged 40-80 years newly treated with antihypertensive drugs during 2010 were identified and followed for 1 year after the first prescription. Discontinuation of treatment was defined as lack of prescription renewal for at least 90 days. Log-binomial regression models were fitted to estimate the risk ratio of treatment discontinuation in relation to sex. Other than for the whole population, analyses were stratified according to age, comorbidity status and the initial antihypertensive treatment strategy. RESULTS Thirty-seven percent of the patients discontinued the drug treatment during follow-up. Compared with women, men had a 10% lower risk of discontinuation of drug treatment (95% confidence interval: 8-12). Persistence on antihypertensive treatment was better in men than in women, this being the case in both younger (40-64 years) and older patients (65-80 years), in patients starting treatment with any major antihypertensive drug and in patients who had a low comorbidity status. There was no evidence that men and women had a different risk of treatment discontinuation when their comorbidity status was worse, or initial antihypertensive treatment was based on drug combinations. CONCLUSION Our data show that in a real-life setting, men are more persistent to antihypertensive drug therapy than women.

Abstract
Blood pressure (BP) is a complex trait that is regulated by multiple physiological pathways and include but is not limited to extracellular fluid volume homeostasis, cardiac contractility, and vascular tone through renal, neural, or endocrine systems. Uncontrolled hypertension (HTN) has been associated with an increased mortality risk. Therefore, understanding the genetics that underpins and influence BP regulation will have a major impact on public health. Moreover, uncontrolled HTN has been linked to inter-individual variation in the drugs’ response and this has been associated with an individual’s genetics architecture. However, the identification of candidate genes that underpin the genetic basis of HTN remains a major challenge. To date, few variants associated with inter-individual BP regulation have been identified and replicated. Research in this field has accelerated over the past 5 years as a direct result of on-going genome-wide association studies (GWAS) and the progress in the identification of rare gene variants and mutations, epigenetic markers, and the regulatory pathways involved in the pathophysiology of BP. In this review we describe and enhance our current understanding of how genetic variants account for the observed variability in BP response in patients on first-line antihypertensive drugs, amlodipine and hydrochlorothiazide.

Abstract
Hypertension was thought to be more important cardiovascular risk factor in men than in women. However, studies showed that overall incidence of hypertension-related cardiovascular diseases is higher in women comparing with men and this is particularly valid in menopause when prevalence of hypertension and its complications sharply and suddenly rises. It was also noticed that the effect of various antihypertensive groups was different in women and men. Some medications are prescribed more often in women, but it does not necessary mean that these drugs are more effective in this gender. There are several important reasons that could explain gender-induced differences in blood pressure levels, blood pressure control and antihypertensive treatment. They involve sex hormones, the renin-angiotensin-aldosterone and sympathetic nervous system, and arterial stiffness. However, taking into account many observational studies and trials, there are no consistent data regarding the impact of gender on effect of antihypertensive medications. Longitudinal study focused on gender and current antihypertensive groups would significantly help to understand the impact of gender. This might change therapeutic approach and improve cost-effectiveness in antihypertensive therapy in both genders. A full understanding of the pathophysiological characteristics of variations between genders demands additional research. This review article summarized the current knowledge regarding differences in the prevalence and awareness of arterial hypertension in women and men; alterations in pathophysiological mechanisms of hypertension between sexes; as well as the impact of sex on the effects of main antihypertensive groups of medications.

Abstract
INTRODUCTION Combination therapy is needed to control blood pressure (BP) in a large number of hypertensive patients with diabetes mellitus. Adherence to treatment is a major clinical problem; therefore, the time duration of the antihypertensive action of a drug determines BP control when a dose is skipped. OBJECTIVES The aim was to determine whether the fixed-dose combination of olmesartan/amlodipine provides equal efficacy and safety as the perindopril/amlodipine combination when a drug dose is missed. METHODS In this noninferiority trial with a randomized, double-blind, double-dummy parallel group, controlled design, 260 patients received either olmesartan 20-40 mg/amlodipine 5-10 mg or perindopril 4-8 mg/amlodipine 5-10 mg for 24 weeks. The main outcome was the sitting office DBP after 24 weeks of treatment at 48 h from last administration. RESULTS The olmesartan/amlodipine combination reached noninferiority criteria in reduction of office DBP after 24 weeks of treatment and after the missed dose, compared with the perindopril/amlodipine combination (-11.7 and -10.5 mmHg, respectively). Office SBP and pulse pressure were significantly lower in both groups after 24 weeks of treatment and 48 h after the missed dose, observing a trend to greater SBP reduction in the olmesartan/amlodipine group. CONCLUSIONS The combination olmesartan/amlodipine is safe, well tolerated, and as effective as the combination of perindopril/amlodipine in the control of essential hypertension in patients with diabetes mellitus. A missed dose does not leave the patients unprotected in both treatments; however, a faster control with less dose increment is observed with olmesartan/amlodipine.

Abstract
BACKGROUND AND OBJECTIVE Adequate control of blood pressure in younger females is of crucial importance, because they are at higher risk of hypertensive target organ damage compared with males of similar age. In addition, female sex is a risk factor for adverse effects of antihypertensive drugs, especially dihydropyridines. This study set out to assess the incidence of adverse reactions during dihydropyridine use in a real-life clinical setting, focusing on the influence of female sex and age. METHODS The incidence of adverse reactions to dihydropyridine calcium channel blockers were investigated in 11,918 Japanese patients who participated in the Drug Event Monitoring project of the Japan Pharmaceutical Association conducted in Kumamoto prefecture. A multiple logistic regression analysis was used to determine the association between the incidence of adverse symptoms and female sex, with adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS Vasodilation-related adverse symptoms occurred significantly more often in females than in males (OR 1.87, 95% CI 1.28-2.71, p=0.001). Furthermore, among females only, the younger age group (<50 years) complained of vasodilation-related symptoms more frequently (OR 2.39, 95% CI 1.02-5.59, p=0.045) and the older age group (≥80 years) complained of vasodilation-related symptoms less frequently (OR 0.56, 95% CI 0.33-0.95, p=0.030) than the middle age group (50-79 years). CONCLUSION To the best of our knowledge, this is the first report showing that younger females are at high risk for vasodilation-related adverse symptoms during dihydropyridine use in a real-life clinical setting. These results should be verified in clinical studies using larger samples of young patients and more parameters.

Abstract
This prespecified subgroup analysis of a phase III study examined the effect of adding hydrochlorothiazide (HCTZ) to olmesartan (OLM)/amlodipine (AML) in patients with moderate to severe hypertension stratified by age, sex, body mass index, and hypertension severity. A total of 2690 patients, aged 18 years and older, with seated blood pressure (SeBP) ≥160/100 mm Hg received placebo or OLM/AML 20/5 mg, 40/5 mg, or 40/10 mg during a 2‐week, double‐blind, run‐in period, after which they were allocated to one of eight treatment groups with the same OLM/AML dose or with HCTZ 12.5 mg or 25 mg added for 8 weeks. By week 10, greater reductions in SeBP were observed in each OLM/AML/HCTZ group (P<.05, respectively) compared with the corresponding dual dose. Adding HCTZ increased blood pressure–lowering efficacy in all subgroups, with a higher proportion of blood pressure goal achievement vs dual therapy. OLM/AML/HCTZ reduced SeBP to a greater extent than OLM/AML in patients with moderate to severe hypertensive; this was unaffected by baseline hypertension severity, age, sex, and obesity.

Abstract
Hypertension, particularly systolic hypertension, is prevalent in the elderly and increases with advancing age, in part because of age-related endothelial dysfunction and increased arterial stiffness. There is strong evidence from randomized clinical trials that supports the use of antihypertensive treatment for effective and sustained blood pressure (BP) control in older patients to reduce the risk of vascular-related morbidity and mortality, particularly cerebrovascular accidents, including stroke. Furthermore, current evidence and guidelines suggest that all major classes of antihypertensive agents are equally effective in controlling BP and preventing cardiovascular events in older patients. Diuretics are commonly used in elderly patients, but recent outcomes data have raised doubt about their long-term benefits. Renin-angiotensin system inhibitors have a better tolerability profile than diuretics. Extensive clinical evidence has demonstrated the excellent efficacy and tolerability profile of olmesartan medoxomil (OM)--an angiotensin II receptor blocker AT1 receptor antagonist--including in elderly patients. Randomized and observational studies have shown that OM provides effective BP control across the 24 h dosing interval in the elderly. It also has a good tolerability profile, a pharmacokinetic profile unaffected by age and a low propensity for drug interactions. An additional factor is that OM once-daily regimens are simple and straightforward, which can be an important factor in maintaining adherence to therapy in elderly patients. This article provides an overview of the main recent clinical evidence supporting the use of OM-based therapy in elderly patients with hypertension.

Abstract
Pharmacological response depends on multiple factors and one of them is sex-gender. Data on the specific effects of sex-gender on pharmacokinetics, as well as the safety and efficacy of numerous medications, are beginning to emerge. Nevertheless, the recruitment of women for clinical research is inadequate, especially during the first phases. In general, pharmacokinetic differences between males and females are more numerous and consistent than disparities in pharmacodynamics. However, sex-gender pharmacodynamic differences are now increasingly being identified at the molecular level. It is now even becoming apparent that sex-gender influences pharmacogenomics and pharmacogenetics. Sex-related differences have been reported for several parameters, and it is consistently shown that women have a worse safety profile, with drug adverse reactions being more frequent and severe in women than in men. Overall, the pharmacological status of women is less well studied than that of men and deserves much more attention. The design of clinical and preclinical studies should have a sex-gender-based approach with the aim of tailoring therapies to an individual's needs and concerns.

Abstract
Background Hypertension is often inadequately controlled in older people. Objective This prespecified subgroup analysis assessed the efficacy and safety of an olmesartan medoxomil (OM) 40 mg/amlodipine besylate (AML) 10 mg/hydrochlorothiazide (HCTZ) 25 mg triple-combination treatment compared with the 3 components as dual-combination treatments in participants with hypertension who were <65 and ≥65 years of age. Within the ≥65 years of age subgroup, efficacy and safety were also summarized for participants ≥75 years of age. Study design 12-week, multicenter, double-blind, randomized, parallel-group study. Setting 317 ambulatory care sites in the US and Puerto Rico. Participants Individuals ≥18 years of age with mean seated blood pressure (SeBP) ≥140/100 or ≥160/90 mmHg off antihypertensive medication on 2 consecutive clinic visits with no recent history of significant cerebrovascular disease, coronary artery disease, heart failure (New York Heart Association class III or IV), severe renal insufficiency, or uncontrolled diabetes (HbA1c >9 %). Intervention Participants were randomized, stratified by age, diabetes status, and race to one of four treatment assignments: OM 40/AML 10/HCTZ 25 mg, OM 40/AML 10 mg, OM 40/HCTZ 25 mg, or AML 10/HCTZ 25 mg. Main Outcome Measure Least squares (LS) mean change from baseline in seated diastolic blood pressure (SeDBP) at week 12 (last observation carried forward) in each age subgroup (prespecified analysis). Results Of the 2492 randomized participants in the study (total cohort), 2021 (81.1 %) were <65 and 471 (18.9 %) were ≥65 years of age, including 79 (3.2 %) who were ≥75 years of age. OM 40/AML 10/HCTZ 25 mg triple-combination treatment resulted in a significantly greater reduction in LS mean SeDBP at week 12 than dual-combination component treatments in participants in both cohorts: <65 years (21.0 vs. 14.2–17.2 mmHg; p < 0.0001) and ≥65 years (23.7 vs. 17.3–20.0 mmHg; p ≤ 0.002). Similarly, triple-combination treatment resulted in a greater reduction in LS mean seated systolic blood pressure (SeSBP) at week 12 than dual-combination component treatments: <65 years (38.2 vs. 28.3–31.4 mmHg; p < 0.0001) and ≥65 years (39.2 vs. 29.3–31.1 mmHg; p < 0.0001). Triple-combination treatment was more effective than dual-combination treatments in enabling participants to reach SeBP goal (<140/90 mmHg [<130/80 mmHg in participants with diabetes, chronic kidney disease, or chronic cardiovascular disease]) in both age subgroups (<65 years: 65 vs. 34–50 %, respectively, p < 0.0001 and ≥65 years: 63 vs. 32–39 %; p ≤ 0.0004). All 4 treatments were safe and well tolerated with low discontinuation rates in both age subgroups. There were no clinically relevant differences in the incidence of treatment-emergent adverse events between participants <65 and ≥65 years of age receiving triple-combination treatment. Conclusion Triple-combination treatment with OM 40/AML 10/HCTZ 25 mg was well tolerated and more effective in lowering BP than the component dual-combination treatments in elderly and non-elderly subgroups.

Abstract
Clinical studies and population-based analyses show that in patients with hypertension, the majority cannot control their blood pressure (BP) by treatment with a single antihypertensive agent. Combining agents from different antihypertensive classes with complementary modes of action significantly increases efficacy and is a treatment strategy recommended by European treatment guidelines, particularly in patients at high cardiovascular risk. The combinations of antihypertensive agents recommended by the European guidelines include an angiotensin receptor blocker (ARB) with a calcium channel blocker (CCB). The single-pill combination formulation of the ARB olmesartan medoxomil plus the CCB amlodipine is an effective and well-tolerated treatment that provides greater blood pressure lowering and control than the component monotherapies and favours compliance by not increasing pill burden. Importantly, the efficacy and tolerability of olmesartan plus amlodipine is not affected by age, gender, hypertension severity, diabetes status, race or body mass index. Additional blood pressure lowering effects are observed with stepwise uptitration of olmesartan plus amlodipine with or without hydrochlorothiazide, with more patients achieving blood pressure goals. In addition, olmesartan plus amlodipine has demonstrated effects beyond BP lowering by showing beneficial effects on markers of inflammation, endothelial dysfunction and oxidative stress, as well as metabolic improvements and a reduction in new-onset diabetes incidence in hypertensive patients with metabolic syndrome.
