Patient adherence and preference considerations in managing cardiovascular risk: focus on single pill and amlodipine/atorvastatin fixed combination

First Iranian guidelines for the diagnosis, management, and treatment of hyperlipidemia in adults

This guideline is the first Iranian guideline developed for the diagnosis, management, and treatment of hyperlipidemia in adults. The members of the guideline developing group (GDG) selected 9 relevant clinical questions and provided recommendations or suggestions to answer them based on the latest scientific evidence. Recommendations include the low-density lipoprotein cholesterol (LDL-C) threshold for starting drug treatment in adults lacking comorbidities was determined to be over 190 mg/dL and the triglyceride (TG) threshold had to be >500 mg/dl. In addition to perform fasting lipid profile tests at the beginning and continuation of treatment, while it was suggested to perform cardiovascular diseases (CVDs) risk assessment using valid Iranian models. Some recommendations were also provided on lifestyle modification as the first therapeutic intervention. Statins were recommended as the first line of drug treatment to reduce LDL-C, and if its level was high despite the maximum allowed or maximum tolerated drug treatment, combined treatment with ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, or bile acid sequestrants was suggested. In adults with hypertriglyceridemia, pharmacotherapy with statin or fibrate was recommended. The target of drug therapy in adults with increased LDL-C without comorbidities and risk factors was considered an LDL-C level of <130 mg/dl, and in adults with increased TG without comorbidities and risk factors, TG levels of <200 mg/dl. In this guideline, specific recommendations and suggestions were provided for the subgroups of the general population, such as those with CVD, stroke, diabetes, chronic kidney disease, elderly, and women.

Combinatorial approaches for novel cardiovascular drug discovery: a review of the literature

INTRODUCTION

In this article, authors report an inclusive discussion about the combinatorial approach for the treatment of cardiovascular diseases (CVDs) and for counteracting the cardiovascular risk factors. The mentioned strategy was demonstrated to be useful for improving the efficacy of pharmacological treatments and in CVDs showed superior efficacy with respect to the classical monotherapeutic approach.

AREAS COVERED

According to this topic, authors analyzed the combinatorial treatments that are available on the market, highlighting clinical studies that demonstrated the efficacy of combinatorial drug strategies to cure CVDs and related risk factors. Furthermore, the review gives an outlook on the future perspective of this therapeutic option, highlighting novel drug targets and disease models that could help the future cardiovascular drug discovery.

EXPERT OPINION

The use of specifically designed and increasingly rational and effective drug combination therapies can therefore be considered the evolution of polypharmacy in cardiometabolic and CVDs. This approach can allow to intervene on multiple etiopathogenetic mechanisms of the disease or to act simultaneously on different pathologies/risk factors, using the combinations most suitable from a pharmacodynamic, pharmacokinetic, and toxicological perspective, thus finding the most appropriate therapeutic option.

Construction of a three-dimensional model of cardiovascular disease and deployment of a new method of fostering patient adherence to instruction

BACKGROUND

For the patient-oriented medical services, it is important to assist the patient in understanding the management of cardiovascular diseases. The strategy of medication instruction is particularly important to enhance medication adherence.

OBJECTIVE AND METHODS

The original model was newly constructed and covers multiple factors, including those related to renin-angiotensin, metabolism of glucose and lipids, blood coagulation, and the organic basis of the disease. The four factors of cardiovascular diseases and their relationship with the disease state are expressed in the form of a tetrahedral model.

RESULTS AND DISCUSSION

This disease model illustrates in points, lines, surfaces, and spaces that the factors combine with each other and result in a pathological condition, as determined by the degree of involvement of each factor in a discontinuous manner. The model helps cardiovascular patients to understand visually that there is more than one pathological condition. Our model allowed patients to quickly comprehend the complex pharmacotherapy of cardiovascular diseases by presenting the information in the form of a three-dimensional structure. Lifestyle-related diseases, including cardiovascular diseases, involve complicated factors and require careful pharmacotherapy which is tailored to individual patient needs. In this regard, the development of instructional tools is particularly effective.

CONCLUSION

The three-dimensional model shows optimum treatment by correctly considering both the quantity and quality of the four pathological factors associated with cardiovascular diseases. Appropriate patient compliance instruction based on life guidance is thought to be essential in the treatment of cardiovascular diseases.

Amlodipine/Atorvastatin: a review of its use in the treatment of hypertension and dyslipidaemia and the prevention of cardiovascular disease

Amlodipine/atorvastatin (Caduet) is a single-tablet, fixed-dose combination of the dihydropyridine calcium channel antagonist amlodipine and the HMG-CoA reductase inhibitor atorvastatin. The bioavailability of amlodipine and atorvastatin with a single-tablet, fixed-dose amlodipine/atorvastatin combination was not significantly different to that with coadministered separate amlodipine and atorvastatin tablets. In well controlled clinical trials in patients with hypertension and dyslipidaemia, once-daily amlodipine and atorvastatin (administered as the single-tablet, fixed-dose combination or coadministered as two separate tablets) effectively reduced systolic BP (SBP) and low-density lipoprotein cholesterol (LDL-C) levels, and enabled more patients to achieve BP and LDL-C goals than single-agent or placebo therapy. There was no modification of the effect of amlodipine on SBP when administered in combination with atorvastatin and there was no modification of the effect of atorvastatin on LDL-C when administered in combination with amlodipine. In noncomparative, titration-to-goal, open-label 'real-world' trials, the single-tablet, fixed-dose combination of amlodipine/atorvastatin enabled patients with hypertension and dyslipidaemia to achieve both BP and LDL-C goals. Administration of a single tablet of amlodipine/atorvastatin, compared with coadministration of these agents as two separate tablets, improved patient adherence, according to a retrospective study that utilized prescription refill rates from a large US insurance database. Data from the large, randomized, double-blind, placebo-controlled ASCOT-LLA trial also demonstrated that the combination of amlodipine-based therapy and atorvastatin was effective in preventing cardiovascular (CV) endpoints in hypertensive patients at risk of CV disease (CVD). In summary, amlodipine/atorvastatin offers a convenient and effective approach to improving adherence and managing CV risk in hypertensive patients with dyslipidaemia or at risk of CVD.
