It is widely recognized that L-NAME exposed rats develop myocardial fibrosis and hypertrophy. The aim of this study was to evaluate the contribution of xanthine oxidase (XO) to these phenomena using allopurinol, isolated or associated with olmesartan. Thirty adult male Wistar rats were divided into 5 groups (n=6) and studied for 5 weeks: L group (L-NAME, 40mg/kg/day); L+A group (L-NAME and allopurinol, 40 mg/kg/day); L+O group (L-NAME and olmesartan, 15mg/kg/day); L+A+O group (L-NAME, allopurinol, and olmesartan); and control group. L-NAME caused arterial hypertension and cardiomyocyte hypertrophy. Hypertension was prevented by olmesartan, but not by allopurinol. There was an increase of left ventricular mass index in the L-NAME group that was prevented by allopurinol, olmesartan and by the combination of both. The increase in mean cardiomyocyte transversal area caused by L-NAME was prevented by the allopurinol and olmesartan combination, or by olmesartan used as monotherapy, but not by allopurinol alone. There was a reduction in the myocardial vascularization index caused by L-NAME which was abolished by allopurinol or by olmesartan, but not by the association. L-NAME caused a reduction in the total number of cardiomyocyte nuclei. This was prevented by olmesartan alone or associated with allopurinol, but not by allopurinol alone. We conclude that XO has an important contribution to adverse cardiac remodeling in L-NAME exposed animals. Moreover, allopurinol acts without interfering with L-NAME induced hypertension. The protective action of this drug is comparable to the results obtained with olmesartan. Antioxidative mechanisms are proposed to account for the pressure independent effects of allopurinol.

Angiotensin receptor antagonists (angiotensin receptor blockers; ARBs) are an effective initial antihypertensive monotherapy in many patients. However, when initial ARB monotherapy fails to achieve the recommended BP goal, there is some controversy as to whether dose uptitration or the addition of a diuretic is more appropriate. This article addresses this issue by reviewing the dose-response characteristics of olmesartan medoxomil and other ARBs, as well as the relationship between ARB uptitration and BP goal attainment. Two types of trial designs are used to assess dose response: dose-ranging studies (usually a parallel design using different doses across different patient groups), which are used to establish the optimal dose for US FDA registration purposes, and dose-titration studies (increased dosing within the same patients and treating to goal BP). Since dose titration is within the same patient, it may be considered more appropriate for demonstrating dose-response characteristics and demonstration of BP goal attainment. While results from dose-ranging studies suggest that the dose-response curve for some ARBs may be flat, dose-titration studies indicate that significant improvements in BP control and BP goal attainment can be achieved with ARB uptitration. In an integrated analysis of seven US and European randomized, placebo-controlled, dose-ranging trials involving 3055 patients with stage 2 hypertension treated with olmesartan medoxomil 2.5-80 mg/day or placebo for 8 weeks, all olmesartan medoxomil doses were significantly more effective than placebo in lowering the mean DBP and mean SBP (p

A total of 623 patients received a 4-week run-in treatment with OM/HCTZ, 341 patients were randomized, and finally, 167 patients in the OM/AML/HCTZ group and 171 patients in the OM/HCTZ group were analyzed for the full analysis set. Non-responders after the 8 weeks of double-blind treatment continued the 8-week open-label treatment with OM/AML/HCTZ 40/5/12.5 mg (n = 32) or OM/AML/HCTZ 20/5/12.5 mg (n = 71). After 8 weeks of double-blind treatment, the changes in msDBP were -9.50 (8.46) mmHg in the OM/AML/HCTZ group and -4.23 (7.41) mmHg in the OM/HCTZ group (both p < 0.0001 vs. baseline; p < 0.0001 between groups). The response rates for both msSBP and msDBP at week 8 were 65.27 % in the OM/AML/HCTZ group and 37.43 % in the OM/HCTZ group (p < 0.0001 between groups). The response rates for both msSBP and msDBP at week 16 after open-label treatment were 18.75 % in the OM/AML/HCTZ 40/5/12.5 group and 46.48 % in the OM/AML/HCTZ 20/5/12.5 group (p = 0.0073 between groups). All medications were well tolerated.

Amiodarone (AD) is one of the most frequently prescribed anti-arrhythmic agents worldwide, but its effectiveness is limited due to the development of pulmonary toxicity. Several lines of evidence have suggested that AT1 receptor antagonists can attenuate pulmonary fibrosis in different animal models. This study was performed to evaluate the effect of olmesartan medoxomil (OM) on lung injury induced in rats by AD which was assessed biochemically (hydroxyproline content, MDA level and SOD activity), histologically (Ashcroft criteria and Masson's trichrome stain) and immunohistochemically (TGF-β1 expression in lung tissue). The expression levels of TGF-β1 and type I collagen mRNA were also determined by quantitative real-time polymerase chain reaction. Forty-eight adult male rats were randomized into six equal groups: control group, OM control groups, AD group received 40 mg/kg/day, p.o. for 4 weeks to induce pulmonary injury in rats and OM-treated groups received 0.6 and 6 mg/kg/day, p.o. concomitantly with AD for the same period. The results indicated that OM significantly decreased collagen deposition and hydroxyproline content, ameliorated pathological score and decreased the elevation in type I collagen and TGF-ß1 mRNA expression in lung tissue. Furthermore, it attenuated the AD-induced increase in the MDA level and increased SOD activity in lung tissue. It can be concluded that OM exerts a protective effect against AD-induced lung damage in rats which is attributed to modulation of pro-fibrogenic cytokine (TGF-β1) and antioxidant effect.

Arterial stiffness is one of the early lesions of the arteries in patients with cardiovascular risk factors. Pulse wave velocity (PWV) is one form of measurement of arterial stiffness. The renin-angiotensin system seems to be involved in the inflammatory mechanisms that take place at level of the vascular wall. The aim of this study is to investigate the effect of olmesartan (angiotensin II type 1 receptor antagonist) in the arterial stiffness, measuring the PWV. Another secondary objective is to determine the antihypertensive efficacy with ambulatory blood pressure monitoring (ABPM).

To evaluate the effect of angiotensin II type1 receptor blocker on nerve regeneration delay in diabetic rats, nerve regeneration was monitored by a pinch test on the crushed sciatic nerves of streptozotocin-induced diabetic rats. Nerve regeneration was significantly delayed in diabetic rats and was partly ameliorated by treatment with olmesartan medoxomil (3 mg/kg/day, orally). In the ipsilateral dorsal root ganglia, the mRNA level of insulin-like growth factor-1 and ciliary neurotrophic factor (CNTF) was downregulated, whereas the mRNA level of neurotrophin-3 and CNTF receptor was upregulated. Olmesartan medoxomil significantly enhanced the CNTF expression. These results showed that angiotensin II type1 receptor blocker treatment is effective on nerve regeneration delay in diabetic animals and may provide an effective therapy for clinical diabetic neuropathy.

Olmesartan medoxomil (OLM) is an antihypertensive angiotensin II receptor blocker. OLM has a low bioavailability (BA), approximately 26% in humans, due to its low water solubility and efflux by drug resistance pumps in the gastrointestinal tract. Self-microemulsifying drug delivery system (SMEDDS), which is easily emulsified in aqueous media under gentle agitation and digestive motility, was formulated to increase the oral BA of OLM. Among the surfactants and oils studied, Capryol 90, Tween 20, and Tetraglycol were chosen and combined at a volume ratio of 1:6:3 on the basis of equilibrium solubility and phase diagram experiments. The mean droplet size of SMEDDS was 15 nm. In an oral absorption study in rats, SMEDDS formulation brought faster absorption compared to suspension, showing a T(max) value of 0.2 hr. The C(max) and AUC values of SMEDDS formulation were significantly higher than those of suspension, revealing a relative BA of about 170%. Our study demonstrated the potential usefulness of SMEDDS for the oral delivery of poorly absorbable compounds, including OLM.

Demographic factors are known to influence the prevalence of hypertension, and evidence suggests that they may also influence the response of patients with hypertension to blood pressure (BP)-lowering therapies. To determine the effect of demographic factors on the efficacy and safety of an olmesartan medoxomil (OM)-based treatment regimen, we performed a prespecified subgroup analysis of a 12-week, randomized, placebo-controlled, titrate-to-goal study in patients with hypertension, stratifying patients into treatment groups according to age, sex, or race. After 12 weeks, OM-based therapy significantly reduced BP from baseline in blacks, non-blacks, men, women, and patients younger than 65 or 65 years and older compared with placebo, and enabled 51.9% to 79.5% of patients to achieve a BP goal of <140/90 mm Hg. The differences in BP-lowering efficacy of OM-based therapy between subgroups were not clinically significant, and treatment was generally well tolerated in all groups. This study demonstrates that an OM-based treatment algorithm is an effective and safe option for achieving recommended BP goal in patients with hypertension including blacks, non-blacks, men, women, and patients younger than 65 or 65 years and older.

Protective effect of valsartan (Val), an angiotensin II (AII)-receptor blocker (ARB), against organ damage is reported to depend on the dosing time in hypertensive patients. Dosing-time-dependent effect of Val on survival of stroke-prone spontaneously hypertensive rats (SHRSP) under a 12-h lighting cycle was examined. Val (4 mg/kg per day) and olmesartan medoxomil (OM) (1 mg/kg per day), another ARB with a slower dissociation from the AII receptor, were given once daily at 2, 8, 14, or 20 HALO (hours after lights on). Dosing-time-dependent differences in plasma drug concentrations and effect on blood pressure (BP) were also evaluated. Survival of SHRSP showed a dosing-time-dependent change during Val therapy, with a peak at 2 HALO and a trough at 14 HALO. OM equally prolonged survival in all groups. The BP-lowering effect persisted for more than 24 h after dosing of Val at 2 HALO and of OM at 2 and 14 HALO, but disappeared at 5.5-h after Val dosing at 14 HALO. Plasma concentrations of Val and OM were higher after dosing at 2 HALO than at 14 HALO. These results suggest that the chronopharmacological phenomenon of Val was partly due to the dosing-time-dependent difference in plasma concentration and subsequent duration of the antihypertensive effect. Slower dissociation of OM from AII receptors might have blunted a potential dosing-time-dependent event.

There is evidence that the activation of renal angiotensin (Ang)-II plays a critical role in the pathogenesis of diabetic kidney diseases (DN) via the ER stress-induced renal apoptosis. Since, the potential negative role of Ang-II in the pathogenesis of ER stress-mediated apoptosis is poorly understood; we evaluated whether treatment of mice with AT-1R specific blocker, olmesartan is associated with the reduction of ER stress-induced renal apoptosis in streptozotocin (STZ)-induced diabetic animal model. We employed western blot analysis to measure the renal protein expressions level of NADPH oxidase subunits, ER chaperone GRP78 and the ER-associated apoptosis proteins. Furthermore, TUNEL staining was used to measure the renal apoptosis. Additionally, dihydroethidium staining and TBARS assay, and immunohistochemistry were performed to measure the renal superoxide radical production and lipid peroxidation, and activation of an Ang-II, respectively. The diabetic kidney mice were found to have increased protein expressions of NADPH oxidase subunits, GRP78 and ER-associated apoptosis proteins, such as TRAF2, IRE-1α, CHOP, p-JNK and procaspase-12, in comparison to normal mice, and which were significantly blunted by the olmesartan treatment in diabetic kidney mice. Furthermore, the diabetic kidney mice were found to have significant increment in renal apoptosis, superoxide radical production, MDA level and activation of an Ang-II and which were also attenuated by the olmesartan treatment. Considering all the findings, it is suggested that the AT-1R specific blocker-olmesartan treatment could be a potential therapy in treating ER stress-induced renal apoptosis via the modulation of AT-1R/CHOP-JNK-Caspase12 pathway in STZ-induced diabetic mice.

Following a 4-week placebo run-in, 440 study participants aged >or=18 years were randomized to olmesartan medoxomil (20 mg/day), amlodipine besylate (5 mg/day), or placebo for 8 weeks. The proportion of participants achieving specific systolic and diastolic ambulatory blood pressure goal levels was calculated by dividing the number of participants who had achieved a particular blood pressure goal by the total number of patients in the intent-to-treat population.

Angiotensin II receptor blockers (ARBs) have been available in the United States since 1995. These agents have demonstrated antihypertensive efficacy at least similar to that of agents from other antihypertensive classes. Recent large-scale, randomized, controlled clinical trials have demonstrated that ARBs offer cardiovascular and renal protective benefits independent of their effects on systemic blood pressure (BP), which make them valuable as first-line antihypertensive agents, especially in high-risk patients. However, as is the case with other antihypertensive classes, monotherapy with the first-available ARBs (losartan potassium, valsartan, and irbesartan) may not provide sufficient BP reduction to achieve currently recommended BP goals in many patients. The diuretic hydrochlorothiazide is frequently added to enhance the ability of ARBs to lower BP. Several head-to-head comparison studies have shown differences in antihypertensive efficacy among the available ARBs. The newest ARB, olmesartan medoxomil, was recently compared with losartan potassium, irbesartan, and valsartan in a prospective, head-to-head, randomized trial. In this study, olmesartan medoxomil demonstrated a significantly greater reduction in diastolic BP, the primary end point, compared with the other three ARBs. Further, a review of the absolute reductions in diastolic BP achieved with olmesartan medoxomil monotherapy appears comparable to that of previously available ARBs when they are used in combination with hydrochlorothiazide. These comparisons may have important clinical implications regarding the optimal choice of first-line antihypertensive therapy.

A total of 80 randomised, controlled trials published between 1973 and 2007 involving 10 818 patients were selected for inclusion in the meta-analytical approach. Data were examined for 19 drugs, and 16 drugs were included in the analysis: hydrochlorothiazide, indapamide sustained-release (SR), atenolol, amlodipine, lercanidipine, manidipine, enalapril, ramipril, trandolapril, candesartan cilexetil, irbesartan, losartan, olmesartan medoxomil, telmisartan, valsartan and aliskiren. Weighted average reductions in SBP and DBP over a period of 8-12 weeks were calculated for each drug from information on both the mean and the variability in BP reduction. No trials evaluating furosemide, spironolactone or cicletanine satisfied the inclusion criteria for this analysis.

In the first study, olmesartan 10 mg/d was compared with losartan 50 mg/d in 316 patients with mild to moderate hypertension (mean baseline buy benicar online diastolic blood pressure [DBP], 95-114 mm Hg). Dosage was doubled at week 4 and hydrochlorothiazide was added at week 12 if blood pressure response was inadequate. Olmesartan was significantly more effective than losartan with respect to the reduction in blood pressure at weeks 2, 4, and 12, and to the responder rate at weeks 2 and 4 (with the starting dose of the respective drug). In a second study, olmesartan 20 mg/d was shown to be significantly more effective than losartan 50 mg/d, valsartan 80 mg/d, and irbesartan 150 mg/d in 588 patients with mild to moderate hypertension (mean sitting baseline DBP, 100-115 mm Hg) (P < or = 0.05). At week 2, the reduction in blood pressure observed with olmesartan was significantly greater than that of the comparator treatments (P < or = 0.05). The superiority of olmesartan was maintained at week 8. The third study involved 643 evaluable patients with moderate to severe hypertension (mean DBP, 100-120 mm Hg; mean systolic blood pressure, >150 mm Hg). Olmesartan 20 mg/d was more effective than candesartan 8 mg/d in lowering 24-hour blood pressure at week 8 (P < or = 0.05). Most of this treatment effect was evident after only 1 or 2 weeks, with greater reductions in blood pressure compared with candesartan.

Recent studies have indicated that both endothelin (ET) and angiotensin (Ang) II stimulate oxidative stress, which contributes to the development of hypertension. Here, we examined the effects of Ang II type 1 (AT1) receptor blockade on reactive oxygen species (ROS) formation in ET-dependent hypertension. Chronic ET-1 infusion (2.5 pmol/kg/min, i.v., n=7) into rats for 14 days increased systolic blood pressure from 113+/-1 to 141+/-2 mmHg. ET-1-infused rats showed greater plasma renin activity (8.1+/-0.8 Ang I/ml/h), and greater Ang I (122+/-28 fmol/ml) and Ang II levels (94+/-13 fmol/ml) than vehicle (0.9% NaCl)-infused rats (3.1+/-0.6 Ang I/ml/h, 45+/-8 and 47+/-7 fmol/ml, respectively, n=6). Angiotensin converting enzyme and AT1 receptor expression in aortic tissues were similar between the vehicle- and ET-1-infused rats. Vascular superoxide anion (O2-) production and plasma thiobarbituric acid-reactive substance (TBARS) levels were greater in ET-1-infused rats (27+/-1 counts per buy benicar online minutes [CPM]/mg dry tissue weight and 8.9+/-0.8 micromol/l, respectively) than vehicle-infused rats (16+/-1 CPM/mg and 5.1+/-0.1 micromol/l, respectively). The ET-1-induced hypertension was prevented by simultaneous treatment with a new AT1 receptor antagonist, olmesartan (0.01% in chow, 117+/-5 mmHg, n =7), or hydralazine (15 mg/kg/day in drinking water, 118+/-4 mmHg, n=6). Olmesartan prevented ET-1-induced increases in vascular O2- production (15+/-1 CPM/mg) and plasma TBARS (5.0+/-0.1 micromol/l). Vascular O2- production and plasma TBARS were also decreased by hydralazine (21+/-1 CPM/mg and 7.0+/-0.3 micromol/l, respectively), but these levels were significantly higher than in vehicle-infused rats. These data suggest that ET-dependent hypertension is associated with augmentation of Ang II levels and ROS formation. The combined effects of the elevations in circulating ET-1 and Ang II, as well as the associated ROS production, may contribute to the development of hypertension induced by chronic ET-1 infusion.

Two simple, economical, rapid, precise, and accurate methods for simultaneous determination of olmesartan medoxomil and hydrochlorothiazide in combined tablet dosage form have been developed. The first method is based on ratio spectra derivative spectrophotometry, and the second method is zero-crossing difference spectrophotometry. The amplitudes in the first derivative of the corresponding ratio spectra at 231.0 and 271.0 nm were selected to determine olmesartan buy benicar online medoxomil and hydrochlorothiazide, respectively. Measurements of absorbance were carried out at zero-crossing wavelengths 257.8 and 240.2 nm for olmesartan medoxomil and hydrochlorothiazide by zero-crossing difference spectrophotometric method. Beer's law is obeyed in the concentration range of 08-24 microg/mL for olmesartan medoxomil (OLM) and 05-15 microg/mL for hydrochlorothiazide (HCT) by ratio spectra derivative and 05-30 microg/mL for OLM and HCT by zero-crossing difference spectrophotometric method. The results of the assay were found to be 100.46+/-0.95 for OLM and 100.4+/-0.27 for HCT by ratio spectra derivative and 99.06+/-1.14 for OLM and 100.05+/-0.90 for HCT by zero-crossing difference spectrophotometric method. These methods passes F test and t test. Both methods were validated statistically and by performing recovery study.

Olmesartan medoxomil (OM) is a prodrug type angiotensin II type 1 receptor antagonist widely prescribed buy benicar online as an antihypertensive agent. Herein, we describe the identification and characterization of the OM bioactivating enzyme that hydrolyzes the prodrug and converts to its pharmacologically active metabolite olmesartan in human liver and intestine. The protein was purified from human liver cytosol by successive column chromatography and was identified by mass spectrometry to be a carboxymethylenebutenolidase (CMBL) homolog. Human CMBL, whose endogenous function has still not been reported, is a human homolog of Pseudomonas dienelactone hydrolase involved in the bacterial halocatechol degradation pathway. The ubiquitous expression of human CMBL gene transcript in various tissues was observed. The recombinant human CMBL expressed in mammalian cells was clearly shown to activate OM. By comparing the enzyme kinetics and chemical inhibition properties between the recombinant protein and human tissue preparations, CMBL was demonstrated to be the primary OM bioactivating enzyme in the liver and intestine. The recombinant CMBL also converted other prodrugs having the same ester structure as OM, faropenem medoxomil and lenampicillin, to their active metabolites. CMBL exhibited a unique sensitivity to chemical inhibitors, thus, being distinguishable from other known esterases. Site-directed mutagenesis on the putative active residue Cys(132) of the recombinant CMBL caused a drastic reduction of the OM-hydrolyzing activity. We report for the first time that CMBL serves as a key enzyme in the bioactivation of OM, hydrolyzing the ester bond of the prodrug type xenobiotics.

This was a multicenter, randomized, double-blind, placebo-controlled, factorial study. Patients who were naive to antihypertensive therapy or who underwent a washout of previous antihypertensive therapy for up to 2 weeks and had a seated diastolic BP (SeDBP) of 95 to 120 mm Hg were randomized to receive 1 of the following for 8 weeks: OM 10, 20, or 40 mg; amlodipine (AML) 5 or 10 mg; each possible combination of OM and AML; or placebo. The primary end point was the change from baseline in SeDBP at week 8, with secondary end points including the change in seated systolic blood pressure (SeSBP), the proportion of patients reaching the BP goal (<140/90 mm Hg; <130/80 mm Hg for patients with diabetes), and the proportions of the intention-to-treat population reaching BP thresholds of <120/80, <130/80, <130/85, and <140/90 mm Hg. Safety and tolerability were also evaluated, with a particular focus on the incidence buy benicar online and severity of edema.

The 2492 randomized patients (52.9% male, 66.8% white, 30.4% black) had a mean (SD) age of 55.1 (10.9) years and a mean weight of 96.0 (22.9) kg. Diabetes was present in 15.5% of the population, chronic cardiovascular disease in 9.1%, and chronic kidney disease in 4.1%. At baseline, the mean SeBP was 168.5/100.9 mm Hg. At week 12, triple combination treatment was associated with significantly greater least squares mean reductions in SeBP compared with the dual combinations (SeDBP: -21.8 vs -15.1 to -18.0 mm Hg, respectively [P < 0.001]; SeSBP: -37.1 vs -27.5 to -30.0 mm Hg [P < 0.001]). A significantly higher proportion of patients receiving triple combination treatment reached BP targets compared with the dual combinations at week 12 (P < 0.001). The proportions of patients reaching the BP target of <140/90 mm Hg at week 12 was 69.9% in the triple combination treatment group and 52.9%, 53.4%, and buy benicar online 41.1% in the treatment groups receiving OM 40 mg/AML 10 mg, OM 40 mg/HCTZ 25 mg, and AML 10 mg + HCTZ 25 mg, respectively (P < 0.001, triple combination vs each dual combination). The incidence of treatment-emergent AEs (TEAEs) was 58.4% for triple combination treatment and 51.7% to 58.9% for the dual combinations; most TEAEs were mild or moderate in severity. The most common TEAEs in the triple combination treatment group were dizziness (9.9%), peripheral edema (7.7%), and headache (6.4%). In total, 52 patients (2.3%) discontinued the study due to TEAEs-6 (1.0%) in the OM 40 mg/AML 10 mg group, 12 (2.1%) in the OM 40 mg/HCTZ 25 mg group, 11 (2.0%) in the AML 10 mg + HCTZ 25 mg group, and 23 (4.0%) in the OM 40 mg + AML 10 mg + HCTZ 25 mg group. Thirty-two patients (1.4%)-4 (0.7%), 5 (0.9%), 5 (0.9%), and 18 (3.1%) in the respective treatment groups-discontinued the study due to drug-related TEAEs.

In order to adequately control hypertension, the majority of patients will require treatment with more than one antihypertensive agent. Fixed-dose combination therapy offers several advantages, including improved efficacy, tolerability, and treatment compliance. Certain combinations have benefits in specific patient populations, such as the elderly or those with comorbidities. In this review, we evaluate the BP-lowering efficacy of olmesartan medoxomil/hydrochlorothiazide (HCTZ) and amlodipine besylate/benazepril in similarly designed, randomized, placebo-controlled studies in similar patient populations. This indirect comparison showed that both combinations significantly Protonix 3 Mg improve both systolic and diastolic BP compared with monotherapy with the individual agents or placebo; it also demonstrated that the combinations were well tolerated. Both combination therapies significantly improved response rates, but olmesartan medoxomil/HCTZ achieved the highest control rates compared with the individual agents. On the basis of an indirect comparison of published factorial design studies, olmesartan medoxomil/HCTZ appears to be at least as effective as amlodipine besylate/benazepril and may provide quantitatively greater reductions in diastolic BP at commonly used dosages. A randomized clinical trial comparing the two combinations is needed to confirm these findings.

Angiotensin-receptor blockers (ARBs) are an important class of agents used for the treatment of arterial hypertension. Olmesartan medoxomil, the seventh latest ARB approved by the US FDA, is an oral, once-daily, AT(1)-receptor selective ARB with high receptor affinity. Pharmacologically, it acts as a competitive and insurmountable Ang II antagonist with linear pharmacokinetics and without cytochrome P450 interaction. The drug is licensed for the treatment of arterial hypertension alone or in combination with other antihypertensive agents. Olmesartan has demonstrated its dose-dependent inhibitory effect on Ang I-induced blood pressure responses between 10 and 80 mg in Phase II studies. These results, confirmed in an international clinical trial programme covering over 3000 hypertensive patients in numerous studies, demonstrated rapid blood pressure-lowering effects within 1 week. A daily oral dose of 20 mg olmesartan is considered to be the optimal dose. In clinical trials and postmarketing studies, olmesartan has been shown to be safe and well tolerated with an adverse event profile Eldepryl Generic Name similar to the placebo. Active comparative studies demonstrated either similar or superior efficacy of olmesartan compared with other ARBs, angiotensin-converting enzymes inhibitors, beta-blockers or calcium-channel blockers. Besides its antihypertensive efficacy, olmesartan was shown in clinical trials to reduce vascular microinflammation, decrease intrarenal vascular resistance, significantly reduce vascular remodeling of small resistance arteries and exert antiatherosclerotic effects by significantly reducing the volume of large atherosclerotic plaques.

Hypertension is a known risk factor for cardiovascular events and mortality. The risk of cardiovascular events increases with age and is linear above 115/75 mm Hg. It also doubles for every 20/10-mm Hg elevation beyond this level and at every age level. Although guidelines vary somewhat by country, the seventh report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends a blood pressure (BP) goal of < 140/90 mm Hg for patients with uncomplicated hypertension and < 130/80 mm Hg for patients with type 2 diabetes mellitus (T2DM) or renal disease. Based on clinical evidence, patients with stage 1 hypertension (seated cuff systolic BP of 140-159 mm Hg or diastolic BP of 90-99 mm Hg) should be treated to targeted BP levels to reduce cardiovascular morbidity and mortality. The angiotensin II receptor blockers (ARBs) are well tolerated and demonstrate significant BP reduction. Olmesartan medoxomil (OM), an ARB, has been well studied and achieves significant BP lowering and goal achievement with good tolerability. Moreover, combination therapy comprising OM plus hydrochlorothiazide can significantly increase BP goal achievement without significantly increasing adverse events. This review evaluates clinical efficacy and safety data from 5 OM-based studies: 4 dose-titration studies and 1 factorial study. Study results demonstrate that OM ± hydrochlorothiazide is highly effective in reducing BP while enabling a majority of patients with stage 1 hypertension to achieve BP goal. In addition, OM tolerability data showed that the high achievement of BP goals was not attained at the expense of increased adverse events. This treatment is associated with low discontinuation rates, even in elderly patients and individuals with T2DM. The clinical data presented in this review support OM-based therapy Amoxil Generic as a rational and safe therapeutic option for patients with stage 1 hypertension.
