Abstract
Pathogens in our environment can act as agents capable of inflicting severe human diseases. Among them, the SARS-CoV-2 virus has recently plagued the globe and paralyzed the functioning of ordinary human life. The virus enters the cell through the angiotensin-converting enzyme-2 (ACE-2) receptor, an integral part of the renin-angiotensin system (RAAS). Reports on hypertension and its relation to the modulation of the RAAS are generating interest in the scientific community. This short review focuses on the SARS-CoV-2 infection's direct and indirect effects on our body through modulation of the RAAS axis. A patient having severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection, which causes COVID-19 relates to hypertension as a pre-existing disease or develops it in a post-COVID scenario. Several studies on how SARS-CoV-2 modulates the RAAS axis indicate that it alters our body's physiological balance. This review seeks to establish a hypothesis on the mechanical dependency of SARS-CoV-2 and RAAS modulation in the human body. This study intends to impart ideas on drug development and designing by targeting the modulation of the RAAS axis to inactivate the pathogenicity of the SARS-CoV-2 virus. A systematic hypothesis can severely attenuate the pathogenicity of the dreadful viruses of the future.

Cocrystal of Apixaban-Quercetin: Improving Solubility and Bioavailability of Drug Combination of Two Poorly Soluble Drugs. Molecules 2021; 26:molecules26092677. [PMID: 34063645 PMCID: PMC8124247 DOI: 10.3390/molecules26092677] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 04/27/2021] [Accepted: 04/28/2021] [Indexed: 11/17/2022] Open
Abstract
Drug combinations have been the hotspot of the pharmaceutical industry, but the promising applications are limited by the unmet solubility and low bioavailability. In this work, novel cocrystals, consisting of two antithrombotic drugs with poor solubility and low bioavailability in vivo, namely, apixaban (Apx) and quercetin (Que), were developed to discover a potential method to improve the poor solubility and internal absorption of the drug combination. Compared with Apx, the dissolution behavior of Apx–Que (1:1) and Apx–Que–2ACN (1:1:2) was enhanced significantly, while the physical mixture of the chemicals failed to exhibit the advantages. The dissolution improvements of Apx–Que–2ACN could be explained by the fact that the solid dispersion-like structure and column-shaped cage of Que accelerated the access of the solvent to the inner layer of Apx. The fracture of the hydrogen bonds of Apx, which was the joint of the adjacent Que chains, facilitated the break-up of the structures. Besides, the bioavailability of Apx–Que was increased compared with the physical mixture and Apx, and Apx–Que remained stable in high temperature and illumination conditions. Therefore, a drug–drug cocrystal of two antithrombotic agents with poor solubility was developed, which exhibited greatly improved solubility, bioavailability and superior stability, indicating a novel method to overcome the shortages of drug combination.

Abstract
Hypertension is an important risk factor for premature death as it increases the probability of stroke, myocardial infarction, and heart failure. Antihypertensive drugs can decrease cardiovascular (CV) morbidity and mortality. The majority of hypertensive patients need more than one antihypertensive agent to attain blood pressure (BP) targets. Monotherapy can effectively reduce BP only in 20%–40% of patients. Multiple mechanisms including increased peripheral vascular resistance, increased cardiac work, and hypervolemia are involved in the pathogenesis of hypertension. Targeting multiple pathways may more potently reduce BP. Increasing the dose of a single agent in many cases does not provide the expected BP-lowering effect because the underlying mechanism of the BP increase is either different or already corrected with the lower dose. Moreover, drugs acting on different pathways may have synergistic effects and thus better control hypertension. It is well known that diuretics enhance the actions of renin–angiotensin aldosterone system and activate it as a feedback to the reduced circulated blood volume. The addition of a renin–angiotensin aldosterone system blocker to a diuretic may more effectively reduce BP because the system is upregulated. Reducing the maximal dose of an agent may also reduce possible side effects if they are dose dependent. The increased prevalence of peripheral edema with higher doses of calcium channel blockers (CCBs) is reduced when renin–angiotensin aldosterone system blockers are added to CCBs through vein dilation. The effectiveness of the combination of enalapril with lercanidipine in reducing BP, the safety profile, and the use of the combination of angiotensin-converting enzyme inhibitors with CCBs in clinical trials with excellent CV hard end point outcomes make this combination a promising therapy in the treatment of hypertension.

Abstract
OBJECTIVE The dose-effect relationship of fixed-dose combinations of anti-hypertensive drugs has been only poorly explored. This pooled analysis investigates the dose-response relationship of fixed-dose lercanidipine + enalapril in patients with mild-to-moderate hypertension. RESEARCH DESIGN AND METHODS This was an individual patient data analysis of four randomized studies (n = 2340). MAIN OUTCOME MEASURES The primary efficacy variable was the change from baseline in sitting diastolic blood pressure (SDBP). Secondary variables were change from baseline in sitting systolic BP (SSBP), proportion of responder patients, and safety. RESULTS All fixed-dose combinations were superior to placebo in the reduction of SDBP. The greatest effect was observed with the market-available combination lercanidipine 20 mg/enalapril 20 mg (-15.3 mmHg vs. baseline; p < 0.05). The reduction in SDBP associated with the other two marketed fixed combinations of lercanidipine/enalapril were -10.7 mmHg for the 10 mg/20 mg combination and -9.8 mmHg for the 10 mg/10 mg combination (p < .05 for both comparisons). Similar findings were reported for SSBP reduction: the greatest effect was observed with lercanidipine 20 mg/enalapril 20 mg (-19.2 mmHg). The reduction in SSBP was -12.5 mmHg for the 10 mg/20 mg combination and -11.1 mmHg for the 10 mg/10 mg combination (p < .05 for all comparisons). The highest responder rate was reported with lercanidipine 20 mg/enalapril 20 mg (75.0%); this figure was 56.1% with the 10 mg/20 mg and 53.0% with the 10/10 mg combination. No safety concerns were reported. CONCLUSION This pooled analysis of four randomized studies shows evidence of a dose-response effect in BP reduction with different fixed combinations of lercanidipine + enalapril. To our knowledge, this is the first analysis investigating the dose-response effect of a specific fixed-dose combination of anti-hypertensive agents. Further studies on this intriguing topic are however necessary.

Abstract
OBJECTIVE This meta-analysis evaluates the efficacy and safety of lercanidipine/enalapril fixed-dose combination in patients with mild to moderate essential hypertension. METHODS Four observational studies on patients with sitting diastolic blood pressure (SDBP) between 95 and 109 mmHg, treated with lercanidipine/enalapril fixed-dose combination, were analyzed. The Random-Effect Model was used to limit heterogeneity across the studies. Weights were applied to determine the influence of each study on the combined results. The efficacy outcome measure was the reduction from baseline to endpoint in systolic and diastolic blood pressure (SBP and DBP, respectively). The incidence of treatment-emergent adverse events (TEAEs) was also investigated. RESULTS The total number of patients analyzed for efficacy and safety was 9565. No differences between study groups in demographics characteristics were observed. Mean blood pressure in the pooled population of the four studies was 162/94 mmHg at baseline. Overall, the lercanidipine/enalapril fixed-dose combination reduced SBP by 26 mmHg (95% CI, 23-29), and DBP by 13 mmHg (12-15), p < 0.05 for both. No safety concerns were reported. CONCLUSION This meta-analysis supports the use of the lercanidipine/enalapril fixed-dose combination for the treatment of mild-to-moderate hypertension.

Abstract
OBJECTIVE The aim of the present study was to compare the effects of the combination of lercanidipine/enalapril versus amlodipine/enalapril and hydrochlorothiazide/enalapril on blood pressure, target organ damage and sympathetic activation in patients with grade 2 essential hypertension. RESEARCH DESIGN AND METHODS This was a 3 month, randomized, blinded-endpoint study in essential hypertensive patients. MAIN OUTCOME MEASURES Office and ambulatory blood pressure, arterial stiffness, urinary albumin to creatinine ratio, renal arterial resistive index, and muscle sympathetic nerve activity were evaluated at baseline, after a 2 week run-in placebo period, at 1 month and at 3 months. RESULTS In total, 56 patients were assigned to lercanidipine/enalapril (n = 19), enalapril/amlodipine (n = 18) and hydrochlorothiazide/enalapril (n = 19). Each pharmacological combination tested was effective in reducing office blood pressure at 1 month and 3 months, and 24 h ambulatory blood pressure at 3 months. Renal arterial resistive index (RI) significantly improved at 1 month and 3 months compared with baseline in all groups. However in the lercanidipine/enalapril and hydrochlorothiazide/enalapril groups, RI was favorably reduced (0.53 ± 0.03 and 0.54 ± 0.04 respectively, p < 0.05) in comparison with the enalapril/amlodipine RI value (0.57 ± 0.03) at 3 months. Moreover, after 3 months of treatment, a significant decrease (by -5.47 bursts/min) (p < 0.05) in muscle sympathetic nerve activity was observed in the lercanidipine/enalapril group (50.79 ± 6.49) compared with baseline (56.26 ± 6.05), while no differences were detected in the amlodipine/enalapril and hydrochlorothiazide/enalapril groups. CONCLUSIONS Our study provides evidence of the efficacy of the lercanidipine/enalapril combination in ameliorating hypertension-related target organ damage and in reducing sympathetic overdrive.

Abstract
Obesity-related hypertension represents a condition frequently observed in current clinical practice characterized by a complex pathophysiological background and a very high cardiovascular risk profile, particularly in severely obese individuals. This explains, on the one hand, the difficulty in reducing elevated blood pressure values in this pathological state and, on the other, the need to achieve this goal in a relatively short-time period to prevent the occurrence of fatal and nonfatal cardiovascular events. Both nonpharmacological and pharmacological measures are available in the therapeutic approach for this condition. Among the pharmacological interventions, a combination of two antihypertensive drugs represents the most common recommended strategy aimed at achieving blood pressure control. This paper, after briefly examining the main pathophysiological features of obesity-related hypertension, will review the importance in the treatment of this condition of the drug combination based on a calcium channel blocker and an angiotensin-converting enzyme inhibitor, with specific focus on lercanidipine/enalapril. Following an analysis of the main pharmacological properties of the combination, the results of the studies based on this pharmacological approach in obesity-related hypertension will be critically discussed. The efficacy, safety, and tolerability profile of the lercanidine/enalapril drug combination as well as its potential limitations will also be examined.

Abstract
Scanty information is available on the effects of combination drug treatment based on an ACE inhibitor and a calcium channel blocker on the neurometabolic alterations characterizing obesity-related hypertension (OHT). After 2-week run-in with enalapril (20 mg), 36 OHTs were randomized according to a double-blind crossover design to a combination therapy with either lercanidipine 10 mg (L) or felodipine extended release 5 mg (F), each lasting 8 weeks. Measurements included clinic and ambulatory blood pressure (BP) and heart rate, homeostasis model assessment index, plasma norepinephrine, and muscle sympathetic nerve activity. Patients with uncontrolled BP were then uptitrated to 20 mg/d (L) and 10 mg/d (F) combined with enalapril 20 mg, respectively, for further 8 weeks. For similar BP reductions, enalapril-lercanidipine (EL) caused norepinephrine and MSNA increases significantly less pronounced than those seen with enalapril-felodipine, the lesser sympathoexcitation observed with EL being coupled with a significant improvement in homeostasis model assessment index. This was the case also when L and F were uptitrated in the combination. In OHT, at variance from enalapril-felodipine, EL combination is almost entirely devoid of any major sympathoexcitatory effect and is associated with an improvement in insulin sensitivity.

Abstract
An improved and reliable ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) method has been developed and validated for the determination of lercanidipine in human plasma. Plasma samples with lercanidipine-d3 as an internal standard (IS) were prepared by solid phase extraction on Phenomenex Strata-X cartridges using 100 µL of human plasma. Chromatographic analysis was performed on UPLC BEH C18 (50 mm×2.1 mm, 1.7 µm) column under isocratic conditions. Linear calibration curves were obtained over a wide dynamic concentration range of 0.010-20.0 ng/mL. Matrix effect was assessed by post-column infusion, post-extraction spiking and standard-line slope methods. The mean extraction recovery was >94% for the analyte and IS. Inter-batch and intra-batch precision (% CV) across five quality controls was <5.8%. Bioequivalence study was performed with 36 healthy subjects after oral administration of 10 mg of lercanidipine and the assay reproducibility was evaluated by reanalysis of 133 incurred samples.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy and safety of combinations of lercanidipine (L) and enalapril (E) at different doses on office and home blood pressure (BP) in patients with Stage 2 hypertension. STUDY DESIGN This was a randomized, double-blind, placebo-controlled, factorial study conducted in 100 centres from seven countries. Patients with office DBP 100-109 mmHg and home DBP at least 85 mmHg at the end of a 2-week placebo run-in period were randomized to a 10-week treatment with placebo, L (10 or 20 mg), E (10 or 20 mg) or the four L-E combinations. The efficacy parameters were office DBP at trough (primary), SBP at trough and home SBP and DBP. Office BP was measured at each visit in both the sitting and the standing position, while home BP was measured twice in the morning and twice in the evening for at least 3 days before treatment and at study end. Safety parameters included adverse events, laboratory tests and 12-lead ECG. RESULTS A total of 1039 patients were randomized (48% men, mean age 54 years, mean BMI 30 kg/m, 40% obese patients). Baseline BP was similar in all groups and lower for home than for office values (149/95 and 159/103 mmHg, respectively). A marked placebo effect was observed on office but not on home BP. Combination therapy was superior to placebo at all doses for both office and home BP. The greatest effect was observed in the L20/E20 group, in which the SBP/DBP fall amounted to -19.2/-15.2 and -13.2/-7.5 mmHg for sitting office and home BP, respectively. Similar reductions were observed on standing office BP. The L20/E20 combination was associated with less cough, palpitations and leg oedema than monotherapies, with no increased rate of dizziness or hypotension. CONCLUSION In Stage 2 hypertension, a fixed-dose combination of L and E ensures a control of both office and out-of-office BP, with a favourable tolerability profile.

Abstract
OBJECTIVE The DUAL study evaluated the effectiveness and safety of the fixed-dose combination of lercanidipine and enalapril in a real-practice scenario; the effects of this combination on a number of markers of cardiovascular risk have been also investigated. RESEARCH DESIGN AND METHODS This was a 2 month, phase IV, open-label, single-group, prospective observational study. Adult patients with untreated or uncontrolled hypertension (blood pressure [BP] >140/90 mmHg) were eligible for this study. All patients received lercanidipine/enalapril, in a once-daily fixed combination (10 mg/10 mg). MAIN OUTCOME MEASURES The patients were evaluated at baseline, at 1 month and at 2 months. The following parameters were evaluated at all time points: systolic BP (SBP) and diastolic BP (DBP); heart rate (HR). A number of laboratory parameters were measured at baseline and at 2 months. Safety considerations were performed. RESULTS In total, 188 patients were enrolled (104 males; mean age 58 ± 12 years). At baseline, mean SBP was 159 ± 10 mmHg and mean DBP was 94 ± 7 mmHg. Treatment with lercanidipine/enalapril in fixed combination was associated with a reduction in both SBP and DBP already at 1 month; this reduction was sustained until month 2 (SBP: 131 ± 7 mmHg; DBP: 79 ± 5 mmHg; p < 0.05 vs baseline). At baseline HR was 78 ± 10 bpm; a significant reduction in this parameter was observed at month 2 (75 ± 7 bpm; p < 0.05 vs baseline). A significant decrease in total cholesterol, low-density lipoprotein cholesterol, triglycerides, and fasting glucose, and a significant increase in K(+), and Ca(2+) was observed at month 2 compared with baseline values. In total, two patients (1%) experienced dry cough. No other adverse effects were reported. CONCLUSIONS Even with all the limitations of any observational study, these data show that a 2 month treatment with a fixed dose of lercanidipine/enalapril is associated with significant reductions in SBP and DBP, HR, and improvement in a number of laboratory parameters.

Abstract
OBJECTIVES To describe new users of antihypertensive medications and identify predictors of combination therapy initiation in older Americans. DESIGN Retrospective observational cohort study. SETTING Population-based study using U.S. Medicare fee-for-service healthcare claims (2007-2010). PARTICIPANTS Medicare beneficiaries aged 65 and older with no recent diagnoses, procedures, or medications for cardiovascular disease who newly initiated an antihypertensive therapy (n = 275,493; 210,605 initiated monotherapy, 64,888 initiated combination therapy). MEASUREMENTS Multivariable Poisson regression was used to assess factors associated with initiation of combination therapy versus monotherapy, including participant characteristics, prescriber characteristics, and participant encounters with the healthcare system. RESULTS Initiation of combination therapy increased from 21.9% in 2007 to 24.7% in 2010. The most frequently initiated combinations were angiotensin-converting enzyme inhibitors with thiazide (29.7%) and angiotensin II receptor antagonists with thiazide (18.7%). Blacks (prevalence ratio (PR) = 1.48, 95% confidence interval (CI) = 1.45-1.51 vs. whites), individuals seeing a generalist (PR = 1.10, 95% CI = 1.07-1.14), individuals seeing more than one doctor (PR = 3.38, 95% CI = 3.33-3.44), and participants with no pharmacy claims in the previous 6 months (PR = 1.34, 95% CI = 1.30-1.37 vs. ≥3 unique drug classes) were more likely to initiate combination therapy, whereas those who had more outpatient visits in the previous 12 months were less likely to initiate combination therapy (per five visits, PR = 0.82, 95% CI = 0.80-0.83). CONCLUSION Nearly one in four new users of antihypertensive medications aged 65 and older started treatment with combination therapy. Blacks, individuals living in the south, and those with fewer outpatient physician office visits were more likely to initiate combination therapy. Further research is needed to determine whether this approach to managing hypertension is being well targeted to individuals who will require combination treatment.

Abstract
Background Fixed-dose combinations of hypertensive drugs have been advocated as a suitable option for hypertensive patients who require two or more drugs to achieve blood pressure (BP) targets. Objectives Our objective was to assess the efficacy and safety of lercanidipine/enalapril in clinical practice. Methods This observational study collected data for patients with hypertension treated by 46 specialists at clinics across Portugal with lercanidipine/enalapril (10/20 mg). The primary outcome measure was the reduction from baseline in systolic BP (SBP) and diastolic BP (DBP). Results The registry enrolled 315 patients (59.1 % females; mean age 64.84 ± 12.18 years). Baseline SBP and DBP were 159.11 ± 16.93 and 88.32 ± 12.35 mmHg, respectively. At a mean 2.88 ± 1.75 months after starting lercanidipine/enalapril, the mean change from baseline in SBP and DBP were −18.08 ± 15.91 and −10.10 ± 11.46 mmHg, respectively (both p < 0.001). This corresponded to reductions of 11.4 and 11.3 % in SBP and DBP, respectively. SBP was reduced independently of sex and age, and DBP was reduced independently of sex. The BP control (<140/90 mmHg) rate significantly increased from 10.2 % at baseline to 51.0 % after a mean of 2.88 months of treatment with lercanidipine/enalapril (p < 0.001). Adverse effects were seen in only one patient (0.3 %), who developed a persistent dry cough. Conclusions Treatment with the fixed-dose combination lercanidipine/enalapril was associated with significant reductions in SBP and DBP, and a significant increase in the BP control rate. This fixed-dose combination has been shown to effectively reduce BP, generally independently of age and sex, and with an excellent safety profile.

Abstract
This review presents the evidence on the benefits of fixed-dose combination therapy for arterial hypertension management. The focus is on the combination of a third-generation dihydropyridine calcium antagonist lercanidipine and an ACE inhibitor enalapril. Lercanidipine is characterised by high vascular selectivity and lipophilicity, good antihypertensive effectiveness, and prolonged, gradually developing therapeutic effects. Literature data on the effectiveness of the lercanidipine-enalapril combination are presented. This combination facilitates a marked reduction in blood pressure levels, which is particularly relevant for elderly patients and patients with diabetes mellitus or obesity. The combination of pharmacologic effects of lercanidipine and enalapril provides additional benefits in terms of organ protection and reduction of adverse effects of the antihypertensive treatment.

Abstract
BACKGROUND Current clinical guidelines recognize that the use of more than one agent is necessary to achieve target BP in the majority of patients. The ASCOT-BPLA trial demonstrated that the free combination of amlodipine and perindopril effectively controlled BP and was better than a beta-adrenoceptor antagonist (beta-blocker)/diuretic combination in reducing total mortality and cardiovascular outcomes. OBJECTIVE To evaluate the efficacy and tolerability of a fixed combination of perindopril and amlodipine in the clinical setting. STUDY DESIGN The STRONG (SafeTy & efficacy analysis of coveRsyl amlodipine in uncOntrolled and Newly diaGnosed hypertension) study was a prospective, observational, multicenter trial. SETTING This was a naturalistic, real-world, clinic-based, outpatient study involving 336 general practitioners/primary care physicians in 65 cities in India. PATIENTS Adults aged 40-70 years with newly diagnosed/untreated stage 2 hypertension (BP >/=160/100 mmHg), hypertension uncontrolled with monotherapy (BP >140/90 mmHg), or hypertension inadequately managed with another combination therapy. INTERVENTION Fixed combination perindopril 4 mg/amlodipine 5 mg once daily for 60 days. MAIN OUTCOMES MEASURE The primary outcomes were the mean change in BP from baseline and the proportion of patients achieving adequate BP control (</=140/90 mmHg, or </=130/80 mmHg in patients with diabetes mellitus) in the intent-to-treat (ITT) population. Secondary analyses included incidence of adverse events (ITT) and treatment adherence rate (completers). RESULTS In total, 1250 patients comprised the ITT population: 32.6% with newly diagnosed hypertension; 40.5% with hypertension uncontrolled with monotherapy; and 26.9% with hypertension inadequately managed with another combination therapy. Mean SBP/DBP decreased significantly from baseline (167.4 +/- 15.2/101.4 +/- 9.1 mmHg) over 60 days (-41.9 +/- 34.8/-23.2 +/- 21.8 mmHg; p < 0.0001). Target BP was achieved in 66.1% of patients in the total population, 68.3% of untreated patients, 68.4% of patients uncontrolled with monotherapy, and 59.9% of patients inadequately managed with combination therapy. In 161 patients with SBP >180 mmHg at baseline (newly diagnosed: n = 50; uncontrolled on monotherapy: n = 53; inadequately managed on combination therapy: n = 58), BP was reduced by 63.2 +/- 32.5/29.0 +/- 21.9 mmHg (p < 0.0001) at day 60. The fixed combination was safe and well tolerated. All 1175 patients completing the 60-day study (94%) adhered to their treatment regimen. CONCLUSION Fixed combination perindopril/amlodipine was found to be an effective and well tolerated antihypertensive treatment, with an excellent rate of treatment adherence in the clinical setting. Fixed combination perindopril/amlodipine is expected to be useful in the management of hypertension in primary healthcare, with a positive impact on treatment adherence.

Abstract
Hypertension is one of the most important and widespread risk factors for the development of cardiovascular disease. Once, combination therapy was traditionally reserved as a third-line or fourth-line approach in the management of hypertension. However, several major intervention trials in high-risk patient populations have shown that an average of 2-4 antihypertensive agents are required to achieve effective blood pressure control. Combination treatment should be considered as a first choice in patients at high cardiovascular risk and in individuals for whom blood pressure is markedly above the hypertension threshold (eg, more than 20 mmHg systolic or 10 mmHg diastolic), or when milder degrees of blood pressure elevation are associated with multiple risk factors, subclinical organ damage, diabetes, renal failure, or associated cardiovascular disease. A number of clinical trials have demonstrated that a fixed combination of lercanidipine and enalapril has better efficacy and tolerability than monotherapy with either agents. The fixed-dose formulation of lercanidipine-enalapril was well tolerated in all clinical trials, with an adverse event rate similar to that of the component drugs as monotherapy. The advantages of combination therapy include improved adherence to therapy and minimization of blood pressure variability. In addition, combining two antihypertensive agents with different mechanisms of action may provide greater protection against major cardiovascular events and the development of end-organ damage.

Abstract
BACKGROUND A fixed-dose combination (FDC) of enalapril and lercanidipine has been shown to be effective and safe in reducing blood pressure in randomized clinical trials. This study aims to determine effectiveness and safety in daily practice. METHODS This was a prospective, open-label, uncontrolled multicenter study, with a 3-month follow-up at general practitioners and internists. Patients were treated with an FDC of 20 mg enalapril maleate and 10 mg lercanidipine hydrochloride, and blood pressure was determined in the office (OBPM) and by discretionary self- (SBPM) and ambulatory- (ABPM) measurements. RESULTS Out of 622 patients (mean age 61.3 ± 13.3 years, 54.2% male): blood pressure was reduced by -29.2/-14.2 mmHg (OBPM) from baseline (164.4/95.2 mmHg). Pulse pressure was reduced by -15.0 ± 16.4 mmHg. Prevalence of microalbuminuria was reduced from 14.6% at baseline to 6.5% (p < 0.001). SBPM data were available for 71% of patients and ABPM for 12%. In the latter patients, blood pressure variability index was significantly reduced compared with baseline over 24 h (14.2 ± 4.2 vs 16.3 ± 4.0; p < 0.001) and with nighttime ABPM (13.7 ± 4.9 vs 15.2 ± 4.4; p = 0.022). Treatment was associated with a low incidence of adverse events (3.4%). CONCLUSIONS The FDC of 20 mg enalapril-maleate and 10 mg lercanidipine-hydrochloride seems to be effective and well tolerated in clinical practice. It improved vascular surrogate end points, including pulse pressure, blood pressure variability and microalbuminuria.

Abstract
Hypertension, a significant factor in the development of cerebrovascular disorders, heart disease and renal failure, is a common disorder worldwide. Despite the availability of a wide range of antihypertensive agents, almost two-thirds of hypertensive patients have poorly controlled blood pressure (BP). Numerous clinical trials have shown that most patients require at least two antihypertensive agents to achieve adequate BP control and associated significant reductions in cardiovascular morbidity and mortality. Combination therapy using two drugs with different, complementary mechanisms of action achieves better efficacy and tolerability outcomes than treatment with either component drug alone. When such a combination is administered as a fixed-dose formulation, other benefits, such as improved compliance and potentially lower costs, are also likely. The good efficacy and tolerability of the combination of a calcium channel antagonist and an angiotensin-converting enzyme inhibitor is well established, and this combination is recommended by European Society of Hypertension/European Society of Cardiology guidelines as a first choice in high-risk hypertensive patients, including those with type 2 diabetes mellitus. Lercanidipine/enalapril is a promising example of a fixed-dose combination of these drug classes. In clinical trials in hypertensive patients, including those with type 2 diabetes, lercanidipine/enalapril improved BP to a greater extent than either drug as monotherapy (in patients who were previous non-responders to lercanidipine or enalapril) or the combination of lercanidipine/hydrochlorothiazide, and was equally well tolerated. Further studies are required to evaluate the cardiovascular protective effects of lercanidipine/enalapril.

Abstract
Achieving optimal blood pressure (BP) control is the most important single issue in the management of hypertension, and in most patients, it is difficult or impossible to achieve target levels with one drug. Blocking two or more regulatory systems provides a more effective and more physiologic reduction in BP, and current guidelines have recommended the use of combination therapy as first-line treatment, or early in the management of hypertension. Fixed-dose combination therapy is an efficacious, relatively safe and cost-effective treatment option in most patients with essential hypertension. Of note, the once-daily administration of a fixed-dose enalapril/lercanidipine, by bringing together two distinct and complementary mechanisms of action, reduces BP effectively and has the potential for improved target organ protection relative to either class agent alone.

Abstract
Despite the development of many effective antihypertensive drugs, target blood pressures are reached in only a minority of patients in clinical practice. Poor adherence to drug therapy and the occurrence of side effects are among the main reasons commonly reported by patients and physicians to explain the poor results of actual antihypertensive therapies. The development of new effective antihypertensive agents with an improved tolerability profile might help to partly overcome these problems. Lercanidipine is an effective dihydropyridine calcium channel blocker of the third generation characterized by a long half-life and its lipophylicity. In contrast to first-generation dihydropyridines, lercanidipine does not induce reflex tachycardia and induces peripheral edema with a lower incidence. Recent data suggest that in addition to lowering blood pressure, lercanidipine might have some renal protective properties. In this review we shall discuss the problems of drug adherence in the management of hypertension with a special emphasis on lercanidipine.

Abstract
Although achieving blood pressure (BP) control is critical to improve cardiovascular prognosis in hypertensive patients, many of them fail to achieve BP goals. The majority of hypertensive patients need more than one antihypertensive agent to attain BP targets. Combination therapy is required when monotherapy fails to attain BP objectives and as a first-line treatment in certain situations, such as markedly elevated BP values, when lower targets are required in high or very high cardiovascular risk patients. The advantages of combination therapy are well documented, with an increased antihypertensive efficacy as a result of the simultaneous inhibition of different mechanisms of action and with a lesser incidence of adverse events, because of the possible compensatory responses and the lower doses used. Calcium channel blockers are effective drugs in the treatment of hypertension. The efficacy of lercanidipine has been evaluated in several noncomparative and in comparative studies showing a great efficacy with a good tolerability. On the other hand, the inhibition of the renin-angiotensin system appears to be very beneficial in the treatment of patients with hypertension. Enalapril is an effective and well tolerated angiotensin converting enzyme inhibitor. Although there are several fixed-combination drugs, the combination lercanidipine plus enalapril appears to be one of the most promising therapies in the treatment of hypertension. The aim of this manuscript is to update the published data about the efficacy and safety of this fixed combination.
