Fixed combination of manidipine and delapril in the treatment of mild to moderate essential hypertension: evaluation by 24-hour ambulatory blood pressure monitoring

Influence of intelligent management mode based on Internet of Things on self-management ability and prognosis of elderly patients with hypertensive heart disease: An observational study

Hypertensive heart disease was difficult to cure with drugs, and most patients had poor compliance, leading to recurrent disease and poor quality of life. The intelligent management mode based on the Internet of Things avoided the excessive dependence of the elderly patients on medical institutions in the traditional medical model and enabled patients to monitor themselves. This study aimed to explore the impact on self-management ability and prognosis of elderly patients with hypertensive heart disease. A total of 150 elderly patients with hypertensive heart disease who received treatment from April 2020 to April 2022 were selected and divided into control group (n = 75 cases) and observation group (n = 75 cases) by random number table method. The control group was given routine intervention, and the observation group was given intelligent management mode based on the Internet of Things. Blood pressure fluctuation, self-management ability, and prognosis of the 2 groups were compared after intervention. After the intervention of the intelligent management mode based on the Internet of Things, the systolic and diastolic blood pressure levels in the observation group were lower than those in the control group (P < .05). After intervention, the scores of self-management ability in diet control, self-care skills, rehabilitation exercise, and self-monitoring in observation group were higher than those in control group (P < .05). After intervention, the total incidence of chest tightness, dyspnea, arrhythmia, edema, and nausea in the observation group was 5 (6.67%), which was significantly lower than that in the control group 12 (16.00%) (P < .05). The application of intelligent management mode based on the Internet of Things could effectively improve patients' blood pressure level, improve patients' self-management ability, and significantly improve the prognosis, which was worthy of popularization and application.

Manidipine plus delapril in patients with Type 2 diabetes and hypertension: reducing cardiovascular risk and end-organ damage

In patients with hypertension and diabetes, atherothrombosis is a leading cause of morbidity and mortality, and there is now compelling evidence demonstrating that lowering elevated blood pressure (BP) is one of the most beneficial aims of therapy in this high-risk population. Indeed, major international guidelines have set a target BP goal of 130/80 mmHg in high-risk patients and recommend combination treatment with two or more drug classes to help achieve this objective. Manidipine plus delapril is a fixed-dose combination of a third-generation dihydropyridine calcium antagonist and an angiotensin-converting enzyme inhibitor, which is effective in mild-to-moderately hypertensive patients with an inadequate response to monotherapy. It is also effective in the long-term (50 weeks) management of essential hypertension. Comparative studies have demonstrated that manidipine plus delapril is as effective as enalapril plus hydrochlorothiazide (HCTZ) in patients with hypertension that is unresponsive to monotherapy, and as effective as ramipril plus HCTZ, valsartan plus HCTZ, irbesartan plus HCTZ and olmesartan plus HCTZ in patients with essential hypertension and Type 2 diabetes. In addition, manidipine plus delapril exhibited renoprotective effects in normotensive Type 2 diabetic patients, and improved fibrinolytic function (significantly more than irbesartan plus HCTZ) in hypertensive patients with Type 2 diabetes. Manidipine 10 mg plus delapril 30 mg once daily was generally well tolerated, with no unexpected adverse effects and evidence of a low incidence of ankle edema. Thus, manidipine plus delapril is a fixed-dose combination treatment that significantly reduces elevated BP with once-daily administration. It is well tolerated and has ancillary properties, such as nephroprotective activity and improvement of fibrinolytic balance, which may help reduce cardiovascular morbidity and mortality, particularly in high-risk patients, such as those with Type 2 diabetes mellitus.

Fixed combination of lercanidipine and enalapril in the management of hypertension: focus on patient preference and adherence

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.

Combination delapril/manidipine as antihypertensive therapy in high-risk patients

The majority of patients with hypertension, and in particular high-risk patients or those with diabetes mellitus or renal dysfunction, are likely to require combination therapy with at least two antihypertensive agents (from different classes) to achieve their blood pressure (BP) target. The delapril/manidipine fixed-dose combination consists of two antihypertensive agents with different, yet complementary, mechanisms of action. Delapril/manidipine has demonstrated short- and long-term antihypertensive efficacy in a number of clinical studies in patients with hypertension with an inadequate response to monotherapy. Comparative studies have demonstrated that delapril/manidipine is as effective as enalapril/hydrochlorothiazide (HCTZ) in patients with hypertension with an inadequate response to monotherapy, and as effective as irbesartan/HCTZ, losartan/HCTZ, olmesartan medoxomil/HCTZ, ramipril/HCTZ and valsartan/HCTZ in reducing BP in patients with hypertension and diabetes, or in obese patients with hypertension. Therapy with delapril/manidipine also appears to exert beneficial effects that extend beyond a reduction in BP, including nephroprotective activity and an improvement in fibrinolytic balance, supporting its value as a treatment option in these patient populations at high or very high cardiovascular risk because of the presence of organ damage, diabetes or renal disease.

Delapril and manidipine measurements by liquid chromatography-tandem mass spectrometry in a pharmaceutical formulation

A simple, specific, fast and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous analysis of delapril (DEL) and manidipine (MAN) from their combination formulation was developed and validated using fesoterodine as the internal standard (IS). The LC-MS/MS method was carried out on a Luna C8 column (50 × 3.0 mm i.d., 3 µm) with a mobile phase consisting of methanol and 10 mmol L(-1) ammonium acetate (90 : 0, v/v), run at a flow rate of 0.25 mL min(-1). The mass spectrometry method was performed employing positive electrospray ionization operating in multiple reaction monitoring mode, monitoring the transitions of m/z 453.1 → 234.1 for DEL, m/z 611.1 → 167.0 for MAN and m/z 412.2 → 223.0 for IS. The total analysis time was 3 min and the method was linear in the concentration range of 6-1080 ng mL(-1) and 2-360 ng mL(-1) for DEL and MAN, respectively. Parameters investigated for the method validation, such as the specificity, linearity, precision, accuracy and robustness, gave results within the acceptable range. Moreover, the proposed method was successfully applied for the simultaneous determination of DEL and MAN and the results were compared to validated liquid chromatography and capillary electrophoresis methods showing non-significant differences (P = 0.9).

Clinical utility and applicability of smoothness index, normalized smoothness index and individualized RDH index during treatment of essential hypertension

The purpose of this study was to assess the clinical utility of the smoothness index (SI) and normalized SI (SIn), measures of duration and homogeneity of blood pressure (BP) reduction, during an observation period without antihypertensive therapy followed by a treatment period using dihydropyridines (DHP) in 54 newly diagnosed and previously untreated subjects (age 46.9 +/- 9.1 years) with essential hypertension. In addition, we aimed to describe the reduction-duration-homogeneity (RDH) index for statistical assessment of the BP reduction in the individual patient. Twenty-four-hour BP was lowered during treatment (139.2 +/- 13.9/ 91.0 +/- 7.6 mmHg vs 130.9 +/- 11.3/85.2 +/- 5.2 mmHg, p < 0.001/p = 0.001). SI showed great interindividual variation, and increased from zero to 0.9 +/- 0.8 (systolic BP) and 0.8 +/- 0.7 (diastolic BP) after treatment (p < 0.001 for both), similar results were obtained for SI(n). The RDH index revealed BP reduction in agreement with the change in individual 24-h, daytime and night-time BP. Although SI and SI(n) may add important information regarding the homogeneity of the antihypertensive effect in a group of patients, and the RDH index for the individual patient, conclusions regarding antihypertensive efficacy can be obtained from assessment of the 24-h, daytime and night-time BP changes and ambulatory BP profiles. Based on our findings, we do not recommend the use of SI or RDH index in the clinical practice.

Effective management of hypertension with dihydropyridine calcium channel blocker-based combination therapy in patients at high cardiovascular risk

The increasing prevalence of hypertension, owing to modern lifestyles and the increasing elderly population, is contributing to the global burden of cardiovascular (CV) disease. Although effective antihypertensive therapies are available, blood pressure (BP) is generally poorly controlled. In addition, the full benefits of antihypertensive therapy can only be realised when target BP is achieved. International guidelines and clinical trial evidence support the use of combination therapy to manage hypertension. In high-risk patients, such as those with coronary artery disease, diabetes and renal dysfunction, BP targets are lower and there is a need for intensive management with combination therapy to control BP and provide additional CV risk reduction benefits. Combinations of antihypertensive agents with different but complementary modes of action improve BP control and may also provide vascular-protective effects. Calcium channel blockers (CCBs) have been shown to be effective in combination with a range of antihypertensive drugs and in different patient populations. As part of a first-line combination strategy, CCBs can provide CV benefits beyond BP control, even in patients at increased CV risk. Benefits include protection against end-organ damage and serious CV events. Indeed, in major intervention trials, these benefits have already been clearly demonstrated. Ongoing studies will provide further data to support the clinical benefits of combination therapy as a first-line treatment approach. Implementation of this approach in clinical practice, together with adherence to global hypertension management guidelines will help ensure patients achieve and sustain BP targets, and reduce the risk of CV events.

Delapril plus indapamide: a review of the combination in the treatment of hypertension

Although many data indicate that the management of hypertension has improved over the last two decades, there is still a large proportion of hypertensive individuals who do not receive adequate management of their blood pressure (BP). Combination therapy with two or more antihypertensive agents from different drug classes is increasingly being recognised as the most effective means of achieving target BP values by pharmacological means, particularly in the large number of patients in whom monotherapy proves to be ineffective. Use of an angiotensin-converting enzyme (ACE) inhibitor combined with a diuretic is a well established antihypertensive combination that is very effective because of the different, yet synergistic, mechanisms of actions of agents from these two drug classes. Delapril is a potent antihypertensive ACE inhibitor, and indapamide is a thiazide-like diuretic with additional antihypertensive properties. The combination of delapril and indapamide provides renoprotective effects, and indapamide is also cardioprotective. Use of these two drugs together is therefore a rational selection for combination therapy, and one that has consistently demonstrated lowering of BP to target values with a level of efficacy that is at least as good as other combinations of ACE inhibitors and diuretics. This combination has also been found to provide favourable effects on haemodynamic parameters, including left ventricular mass index and ejection fraction. Furthermore, combining an ACE inhibitor and a thiazide-type diuretic has been associated with a decreased risk of stroke and is recommended for patients with cerebrovascular disease, a setting in which the combination of delapril and indapamide has therapeutic potential. Because of the additive mechanisms of delapril and indapamide, the dose required for an effective antihypertensive effect is relatively low, and the combination is well tolerated at such doses. In particular, metabolic effects normally associated with diuretics are rare at the therapeutic dose of indapamide used in combination with delapril, making the combination suitable for patients with metabolic disorders in whom diuretic therapy would otherwise not be recommended. Delapril 30 mg and indapamide 2.5mg have been combined in a fixed combination, offering the convenience of a one-tablet-per-day antihypertensive drug regimen for most patients, which, along with good tolerability, helps to address the issue of noncompliance.

Fixed-Drug Combinations as First-Line Treatment for Hypertension

As combinations of drugs from different classes that have synergistic or additive effect and properties to cancel out each others' untoward hemodynamic and metabolic effects become more and more widely used, their use as first-line therapy for the treatment of newly diagnosed hypertensive patients is growing in popularity as well. The possibility to begin therapy with a fixed 2-drug combination may be preferable to starting with monotherapy followed by upward titration and addition of other agents. More and more combinations are coming out on the market and proving their effectiveness in randomized controlled trials and in large multicenter studies. One suggestion is the "polypill," a fixed combination of multiple agents that address various components of the metabolic syndrome and coexisting common risk factors in both high-risk patients with conditions requiring polypharmacy, and in healthy asymptomatic individuals.
