[PMID: 39103062 DOI: 10.1016/j.ijpharm.2024.124550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 07/16/2024] [Accepted: 08/02/2024] [Indexed: 08/07/2024]
Abstract
This review explores the feasibility of extrusion-based 3D printing techniques for producing complex dosage forms (such as capsular shells/devices) that provide controlled drug release and targeted delivery. The current discussion explores how extrusion-based 3D printing techniques, particularly Fused Deposition Modelling (FDM) and Pressure-Assisted Modelling (PAM), offer significant advantages in fabricating such complex dosage forms. This technology enables the fabrication of single-, dual-, or multi-compartment capsular systems with customized designs/geometry of the capsular shell to achieve delayed, sustained, or pulsatile drug release. The impact of customized design/geometry on the biopharmaceutical performances of loaded therapeutics is comprehensively discussed. The potential of 3D printing techniques for different specialized drug delivery purposes like gastric floating, implants, suppositories, and printfills are also addressed. This technique has the potential to significantly improve the therapeutic outcomes, and patient adherence to medication regimens, and pave the way for personalized medicine.

Abstract
With the advent of personalized medicine, the drug delivery system will be changed significantly. The development of personalized medicine needs the support of many technologies, among which three-dimensional printing (3DP) technology is a novel formulation-preparing process that creates 3D objects by depositing printing materials layer-by-layer based on the computer-aided design method. Compared with traditional pharmaceutical processes, 3DP produces complex drug combinations, personalized dosage, and flexible shape and structure of dosage forms (DFs) on demand. In the future, personalized 3DP drugs may supplement and even replace their traditional counterpart. We systematically introduce the applications of 3DP technologies in the pharmaceutical industry and summarize the virtues and shortcomings of each technique. The release behaviors and control mechanisms of the pharmaceutical DFs with desired structures are also analyzed. Finally, the benefits, challenges, and prospects of 3DP technology to the pharmaceutical industry are discussed.

Abstract
Patients with heart failure (HF) have a high prevalence of polypharmacy, which can lead to drug interactions, cognitive impairment, and medication non-compliance. However, the definition of polypharmacy in these patients is still inconsistent. The aim of this scoping review was to find the most common definition of polypharmacy in HF patients. We conducted a scoping review searching Medline, Embase, CINAHL, and Cochrane using terms including polypharmacy, HF and deprescribing, which resulted in 7,949 articles. Articles without a definition of polypharmacy in HF patients and articles which included patients < 18 years of age were excluded; only 59 articles were included. Of the 59 articles, 49% (n = 29) were retrospective, 20% (n = 12) were prospective, 10% (n = 6) were cross-sectional, and 27% (n = 16) were review articles. Twenty percent (n = 12) of the articles focused on HF with reduced ejection fraction, 10% (n = 6) focused on HF with preserved ejection fraction and 69% (n = 41) articles either focused on both diagnoses or did not clarify the specific type of HF. The most common cutoff for polypharmacy in HF was five medications (59%, n = 35). There was no consensus regarding the inclusion or exclusion of over-the-counter medications, supplements, or vitamins. Some newer studies used a cutoff of 10 medications (14%, n = 8), and this may be a more practical and meaningful definition for HF patients.

Abstract
Objectives This study aimed to determine the prevalence, characteristics and determinants of polypharmacy among elderly patients in Bahrain. Methods This cross-sectional study was conducted between March and April 2022 in all primary healthcare centres in Bahrain. A simple random sample was obtained. An elderly patient was defined as one aged ≥60 years and polypharmacy was defined as the concomitant use of 5 or more medications, with excessive polypharmacy defined as the concomitant use of 10 or more medications. Results A total of 977 patients were included, with more than half of them being females (n = 533, 54.55%) and the mean age of the participants at 67.90 ± 6.87 years. Essential hypertension, hyperlipidaemia and diabetes mellitus were the most common comorbidities among the participants (61.51%, 57.63% and 53.22%, respectively). Among the cohort, 443 (45.34%) were on 5 or more medications and of those 66 (6.76%) were on at least 10 medications. A multivariate analysis revealed that patients with diabetes (odds ratio [OR] = 5.836, 95% confidence interval [CI]: 4.061-8.385; P <0.001), hypertension (OR = 6.231, 95% CI: 4.235-9.168; P <0.001), hyperlipidaemia (OR = 3.999, 95% CI: 2.756-5.802; P <0.001), cardiovascular diseases (OR = 3.589, 95% CI: 1.787-7.205; P <0.001) and asthma (OR = 3.148, 95% CI: 1.646-6.019; P <0.001) were significantly more likely to suffer from polypharmacy. Conclusion Polypharmacy is prevalent among elderly patients in Bahrain, particularly among those with non-communicable diseases. Polypharmacy should be considered while delivering healthcare services to the elderly, especially those with non-communicable diseases.

Abstract
Whilst monotherapy is traditionally the preferred treatment starting point for chronic conditions such as hypertension and diabetes, other diseases require the use of multiple drugs (polytherapy) from the onset of treatment (e.g., human immunodeficiency virus acquired immunodeficiency syndrome, tuberculosis, and malaria). Successful treatment of these chronic conditions is sometimes hampered by patient non-adherence to polytherapy. The options available for polytherapy are either the sequential addition of individual drug products to deliver an effective multi-drug regimen or the use of a single fixed-dose combination (FDC) therapy product. This article intends to critically review the use of FDC drug therapy and provide an insight into FDC products which are already commercially available. Shortcomings of FDC formulations are discussed from multiple perspectives and research gaps are identified. Moreover, an overview of fundamental formulation considerations is provided to aid formulation scientists in the design and development of new FDC products.

Abstract
Although the cardiovascular (CV) polypill concept is not new and several guidelines state that a CV polypill should be considered an integral part of a comprehensive CV disease (CVD) prevention strategy, there are still some barriers to its implementation in the real-world setting, mainly in secondary CV prevention. As the CNIC-polypill is the only one approved for secondary CV prevention in patients with atherosclerotic CVD in 27 countries worldwide, a panel of four discussants and 30 participants from 18 countries conveyed in a virtual meeting on April 21, 2022, to discuss key clinical questions regarding the practical use of the CNIC-Polypill and barriers to its implementation.Data presented showed that, although the use of the CV polypill is not explicitly mentioned in the current 2021 European Society of Cardiology guidelines on CVD prevention, it may be used in any patient for secondary CVD prevention tolerating all their components to improve outcomes through different aspects. The favourable results of the Secondary Prevention of Cardiovascular Disease in the Elderly (SECURE) trial now reinforce this recommendation. The panellists presented algorithms on how to switch from any baseline regimen when starting treatment with the CNIC-polypill in different situations, including patients with hypertension, dyslipidaemia, and a previous CV event; at discharge after a cardiovascular event; in chronic ischemic conditions; and in cases of polypharmacy. The panellists and expert discussants did agree that available studies conducted so far with the CNIC-polypill demonstrate that it is as efficacious as the monocomponents, equipotent drugs, or other therapies; reduces the risk of experiencing recurrent major CV events; improves medication adherence; reduces health care costs and resources compared to patients treated with loose drugs; and the patients prefer it over the multipill strategy.In conclusion, the data presented by the participants provided the evidence behind the use of the CNIC-polypill to help fulfil the goal of encouraging its adoption by physicians.

Abstract
BACKGROUND Metabolic dysfunction-associated fatty liver disease (MAFLD) is a novel term that distinguishes patients at risk of adverse clinical outcomes with higher accuracy than those with non-alcoholic fatty liver disease (NAFLD). Cardiovascular mortality is the leading cause of death in MAFLD. The current literature lacks large-scale prospective studies that address preventive approaches for cardiovascular health in MAFLD. We investigated whether MAFLD patients benefit from a fixed-dose combination therapy (Aspirin, hydrochlorothiazide, atorvastatin, valsartan), known as a Polypill. METHODS Analysis was performed (stratified based on MAFLD status) of a clinical trial that included 1596 individuals randomly allocated to an intervention (polypill) or a control (usual care) group. Patients were followed up for five years for any adverse drug reaction, major cardiovascular events, and mortality. Univariable and multivariable survival analyses were performed, and the interaction level was assessed by R programming. RESULTS Patients who consumed the polypill had significantly lower hazard ratios of major cardiovascular events incidence (HR 0.56, 95% CI 0.41-0.78) and cardiovascular mortality (HR 0.41, 95% CI 0.2-0.86) compared to the control group. Polypill showed significantly better results in lowering cardiovascular events in MAFLD patients than in the general population. (p-value for interaction: 0.028). Moreover, comparing those patients who had high adherence to the Polypill, with the control group, further enhanced the results. CONCLUSIONS Major cardiovascular events are prevented in MAFLD patients who consume the Polypill. MAFLD patients benefit from the Polypill more than the general population.

Abstract
Providing quality cardiovascular disease (CVD) care in low resource setting requires understanding of priority and effective interventions. This study aimed to identify and prioritize evidence-based quality improvement strategies for CVD care in India using a modified two-round Delphi process in which, we asked 46 experts (clinicians, researchers, program implementers and policy makers) to rate 25 proven CVD care strategies grouped into: (1) patient support, (2) information communication technology (ICT) for health, (3) group problem solving, (4) training, and (5) multicomponent strategy on a scale of 1 (highest/best)-5 (lowest/worst) on priority, relative advantage, and feasibility. Subsequently, we convened an expert consensus panel of 32 members to deliberate and achieve consensus regarding the prioritized set of strategies for CVD care. The Delphi study found that group problem solving strategies achieved the best score for priority (1.80) but fared poorly on feasibility (2.88). Compared to others, multicomponent strategies were rated favorably across all domains (priority = 1.84, relative advantage = 1.94, and feasibility = 2.40). The ICT for health strategies achieved the worst scores for priority = 2.01, relative advantage = 2.31, and feasibility = 2.85. Training and patient support strategies scored moderately across all domains. The expert panel narrowed the selection of a multicomponent strategy consisting of (1) electronic health records with clinical decision-support system, (2) non-physician health worker facilitated care, (3) patient education materials, (4) text-message based reminders for healthy lifestyle, and (5) audit and feedback report for providers. Future research will evaluate the real-world feasibility and effectiveness of the multicomponent strategy in patients with CVD in a low- and middle-income country setting.

Abstract
BACKGROUND The effectiveness of polypill therapy in the prevention and treatment of cardiovascular disorders is still unclear. This meta-analysis aimed to assess the efficacy of polypill therapy in reducing cardiovascular risk factors. METHODS We conducted a systematic search of PubMed, Cochrane CENTRAL, SCOPUS, and Google Scholar for randomized controlled trials (RCTs) that evaluated polypill therapy for cardiovascular diseases, hypertension, or dyslipidemia. We included 18 RCTs with a total of 20,463 participants in our analysis. Pooled effect estimates were reported as Odds ratios (ORs) with a 95% confidence interval (CI) using a random-effects model. RESULTS Polypill therapy was associated with a statistically significant reduction in systolic blood pressure (SBP) [OR: -0.33, 95% CI (-0.64, -0.03); P-value= 0.03], diastolic blood pressure (DBP) [OR: -0.70, 95% CI (-1.20, -0.21); P-value= 0.005], and total cholesterol level [OR: -1.25, 95% CI (-1.82, -0.68); P-value < 0.0001]. Polypill therapy also showed improved adherence [OR 2.18, 95% CI (1.47, 3.24); P-value= 0.0001]. However, there was no statistically significant benefit in the reduction of all-cause mortality, major cardiovascular events, and LDL-c levels. CONCLUSIONS The use of polypill therapy is associated with a statistically significant reduction in SBP, DBP, and total cholesterol levels, as well as improved adherence. Further research is needed to determine its impact on hard clinical outcomes such as mortality and major cardiovascular events.

Abstract
The low bioavailability of orally administered drugs as a result of the instability in the gastrointestinal tract environment creates significant challenges to developing site-targeted drug delivery systems. This study proposes a novel hydrogel drug carrier using pH-responsive materials assisted with semi-solid extrusion 3D printing technology, enabling site-targeted drug release and customisation of temporal release profiles. The effects of material parameters on the pH-responsive behaviours of printed tablets were analysed thoroughly by investigating the swelling properties under both artificial gastric and intestinal fluids. It has been shown that high swelling rates at either acidic or alkaline conditions can be achieved by adjusting the mass ratio between sodium alginate and carboxymethyl chitosan, enabling site-targeted release. The drug release experiments reveal that gastric drug release can be achieved with a mass ratio of 1:3, whilst a ratio of 3:1 allows for intestinal release. Furthermore, controlled release is realised by tuning the infill density of the printing process. The method proposed in this study can not only significantly improve the bioavailability of oral drugs, but also offer the potential that each component of a compound drug tablet can be released in a controlled manner at a target location.

Abimbola S, Liu H. Adoption and scale-up of the cardiovascular Polypill: a realist institutional analysis. Health Policy Plan 2023; 38:15-27. [PMID: 36271837 PMCID: PMC9825725 DOI: 10.1093/heapol/czac088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 09/28/2022] [Accepted: 10/21/2022] [Indexed: 01/12/2023] Open
Abstract
Efforts to promote the adoption and scale-up of health system innovations must contend with the existing institutional context. But there are no commonly used frameworks to ensure that the insights of actors involved in such institutional efforts connect to one another. To test and modify a potential framework-the 'four-by-four' framework-we interviewed researcher-entrepreneurs involved in the unfolding story of the cardiovascular Polypill. The framework has four types/levels of institutions that affect adoption and scale-up: (1) informal institutions (L1, e.g. social norms), (2) formal institutions (L2, e.g. government policies and regulation), (3) organizational structures (L3, e.g. organizational boards and mission) and (4) everyday exchange (L4, e.g. service delivery), vis-à-vis four potential entrepreneurial strategies in response: (1) abide by existing institutions, (2) evade them, (3) alter them and/or (4) exit entrepreneurial action. Using this framework, we conducted a realist-informed analysis to understand how context (i.e. institutions) and mechanism (i.e. entrepreneurial strategies) influence each other to shape outcomes (i.e. adoption and scale-up). We found that researcher-entrepreneurs began with efforts to abide with existing institutions but encountered institutional obstacles at each level. Efforts to abide were followed by seeking to evade and/or alter unfavourable institutions, with greater success evading and/or altering lower (L3 and L4) than upper (L1 and L2) institutions. Exit considerations followed the failure of the evade or alter strategy. Shifts between strategies were propelled by 'learning'. The 'four-by-four' framework can be used as a scaffold to generate narratives of adoption or scale-up efforts, a sensitizing tool to prospectively map out contingencies and a matrix to synthesize narratives and experiences across multiple innovations or settings. Used in these ways, the 'four-by-four' framework can help to optimize the transferability and cumulation of insights on how to promote the adoption and scale-up of health system innovations.

Abstract
Current cholesterol guidelines for primary prevention of atherosclerotic cardiovascular disease (ASCVD) base statin treatment decisions on multiple risk factor algorithms (e.g., Pooled Cohort Equations [PCEs]). By available PCEs, most older middle-aged men are statin eligible. But several studies cast doubt on predictive accuracy of available PCEs for ASCVD risk assessment. Recent studies suggest that accuracy can be improved by measurement of coronary artery calcium (CAC). This method has the advantage of identifying men at low risk in whom statin therapy can be delayed for several years, provided they are monitored periodically for progression of CAC. Thus, there are two approaches to statin therapy in men ≥ 55 years: first all men could be treated routinely, or second, treatment can be based on the extent of coronary calcium. The latter could allow a sizable fraction of men to avoid treatment for several years or indefinitely. Whether with initial CAC scan or with periodic rescanning, a CAC score ≥ 100 Agatston units is high enough to warrant statin therapy. In otherwise high-risk men (e.g., diabetes, severe hypercholesterolemia, 10-year risk by PCE ≥ 20%), a statin is generally indicated without the need for CAC; but in special cases, CAC measurement may aid in treatment decisions.

Cost-effectiveness of fixed-dose combination pill (Polypill) in primary and secondary prevention of cardiovascular disease: A systematic literature review. PLoS One 2022; 17:e0271908. [PMID: 35901100 PMCID: PMC9333258 DOI: 10.1371/journal.pone.0271908] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 07/08/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND A significant proportion of cardiovascular disease (CVD) morbidity and mortality could be prevented via the population-based and cost-effective interventions. A fixed-dose combination treatment is known as the polypill for the primary and secondary prevention of CVD has come up in recent years. PURPOSE In order to provide recommendations for future economic evaluations, this systematic review aimed to review and assess the quality of published evidence on the cost-effectiveness of polypill in primary and secondary prevention of CVD, to identify the key drivers that impact the cost-effectiveness. METHODS A systematic review of literature, following the PRISMA guidelines, was undertaken in the electronic databases. Two researchers identified the relevant studies according to inclusion and exclusion criteria. Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to quality assessment of included studies. ICERs value adjusted to 2020 United States Dollar using consumer price index (CPI) and purchasing power parity (PPP). Finally, data were summarized via a narrative synthesis. RESULTS In total, 24 articles were identified based on the determined inclusion criteria. All studies met more than 50% of the CHEERS criteria. Adjusted incremental cost-effectiveness ratios varied from 24$ to 31000$(2020 US dollar) among the studies. The polypill resulted in the improved adherence and quality of life, at a price equal to or lower than multiple monotherapies. This price is typically below the commonly accepted thresholds or cost saving in both, primary and secondary prevention of CVD. The main identified cost-effectiveness drivers were the polypill price, adherence, age, CVD risk, and drug combination. CONCLUSIONS This systematic review found that the polypill seemed to be a cost-effective intervention in primary and secondary prevention of CVD. However, it is necessary to conduct more economic evaluation studies based on the long-term clinical trials with large populations. Also, studies should consider how the polypill interacts with other primary and secondary preventive strategies as a complementary health strategy.

Abstract
A polypill-type strategy for primary prevention was first published at the turn of the century and advised that a multi-ingredient pill applied to an adult population would prevent up to 80% of cardiovascular and stroke events. Such a pill should contain small doses of antihypertensives, lipid-lowering drugs, and some nutrients. The startling increase of the global stroke burden has led to a revival of this concept and the propagation of a population-based prevention strategy. Recent cardiovascular fixed-dose combination trials have shown a significant effect in reducing not only blood pressure and cholesterol levels but also in reducing cardiovascular and stroke events. In most of the studies, the study population was for secondary prevention and the total number of strokes was small. Nevertheless, it is now clear that a large proportion of primary prevention must take this path. It is especially promising when combined with community health workers interventions for modifying risk behavior. While a polypill-type approach seems most efficacious in underserved regions of high-income countries as well as in low- and middle-income countries, it seems to have a large overall effect in spite of some problems with nonadherence or potential side effects. It should be available and affordable for large target populations. Larger phase 4 studies are under way.

Abstract
Cardiovascular Diseases (CVD) are the leading cause of mortality globally. Wald and Law proposed the idea of a 'polypill'; a fixed dose combination therapy (FDC) in the form of a single pill to curb the CVD epidemic. Such a drug would include the combination of a broad spectrum of drugs including cholesterol lowering drugs, antihypertensive drugs, anti-platelet drugs, anti-coagulation drugs, anti-arrhythmic drugs, which are frequently integrated to combat specific CVDs. This 'polypill' holds the potential to pose several advantages like increased compliance, improved quality of life, risk factor control, psychological relief, and cost effectiveness along with minimal side effects. Several trials (like TIPS, UMPIRE, PolyIran etc.) have tested different treatment strategies to test the hypothesis of Wald and Law. Unlike the past physicians are now highly aware of this new strategy.The future of polypill in the management of CVD lies in a strategy where polypills are treated supplementary to the already existing preventive care, which includes lifestyle modifications and efforts to reduce tobacco use.

Abstract
PurposeTo evaluate the effect of polypills on the primary prevention of cardiovascular (CV) events using data from clinical trials.MethodsWe searched PubMed, Web of Science, EBSCO, and SCOPUS throughout May 2021. Two authors independently screened articles for the fulfillment of inclusion criteria. The RevMan software (version 5.4) was used to calculate the pooled risk ratios (RRs) and mean differences (MDs), along with their associated confidence intervals (95% CI).ResultsEight trials with a total of 20653 patients were included. There was a significant reduction in the total number of fatal and non-fatal CV events among the polypill group [RR (95% CI) = 0.71 (0.63, 0.80); P-value < 0.001]. This reduction was observed in both the intermediate-risk [RR (95% CI) = 0.76 (0.65, 0.89); P-value < 0.001] and high-risk [RR (95% CI) = 0.63 (0.52, 0.76); P-value < 0.001] groups of patients. Subgroup analysis was performed based on the follow-up duration of each study, and benefits were only evident in the five-year follow-up duration group [RR (95% CI) = 0.70 (0.62, 0.79); P-value < 0.001]. Benefits were absent in the one-year-or-less interval group [RR (95% CI) = 0.77 (0.47, 1.29); P-value = 0.330]. Additionally, there was a significant reduction in the 10-year predicted cardiovascular risk in the polypill group [MD (95% CI) = −3.74 (−5.96, −1.51); P-value < 0.001], as compared to controls.ConclusionA polypill regimen decreases the incidence of fatal and non-fatal CV events in patients with intermediate- and high- cardiovascular risk, and therefore may be an effective treatment for these patients.

Abstract
Over the last 2 decades, the management of chronic disease in Korea has been improved, but it has gradually stagnated. In order to improve care and reduce cardiovascular morbidity and mortality, it is crucial to improve primary prevention of cardiovascular diseases. In recent international guidelines for hypertension, diabetes, hyperlipidemia, obesity, and other conditions, adherence issues have become more frequently addressed. However, in terms of implementation in practice, separate approaches by dozens of related academic specialties need to be integrated into a systematic approach including clinician’s perspectives such as the science behind adherence, clinical skills, and interaction within team approach. In primary prevention for cardiovascular diseases, there are significant barriers to adherence including freedom from symptoms, long latency for therapeutic benefits, life-long duration of treatment, and need for combined lifestyle changes. However, to implement more systematic approaches, the focus on adherence improvement needs to be shifted away from patient factors to the effects of the treatment team and healthcare system. In addition to conventional educational approaches, more patient-oriented approaches such as patient-centered clinical communication skills, counseling using motivational strategies, decision-making by patient empowerment, and a multi-disciplinary team approach should be developed and implemented. Patients should be involved in a program of self-monitoring, self-management, and active counseling. Because most effective interventions on adherence improvement demand greater resources, the health care system and educational or training system of physicians and healthcare staff need to be supported for systematic improvement.

Abstract
OBJECTIVE This work aims to analyze the impact of Spain's National Center for Cardiovascular Research (CNIC-Ferrer)'s cardiovascular (CV)-polypill on blood pressure (BP) and low-density lipoprotein cholesterol (cLDL) levels in patients in our healthcare area who previously took equipotent doses of statins and antihypertensives. MATERIAL AND METHODS All patients in our healthcare area (Santiago de Compostela, Spain) who, as of December 31, 2019, had an active prescription for the CV-polypill (CNIC-Ferrer) since January 16, 2015 were registered. The index date was the start date of the CV-polypill prescription. The drugs the patient had previously received for dyslipidemia and hypertension were analyzed, classifying them by their equivalent potency to atorvastatin and ramipril. Changes in cLDL and BP were analyzed by means of Student's t-test for paired samples. RESULTS We analyzed 547 patients with a mean age of 71.5 ± 11.5 years. The majority were men (60.6%). We observed a decrease in cLDL (-10.6 [95% CI: -7.0, -14.3], p < 0.001) in patients who started taking the CV-polypill who had previously taken equally potent doses of atorvastatin (n = 471). We documented a reduction in systolic BP (-3.7 [95% CI: -0.4, -6.9], p = 0.029) in patients who had previously taken equally potent doses of ramipril (n = 360). In 88 patients, the CV-polypill was started via equally potent doses of atorvastatin and ramipril, with a decrease in cLDL (-8.7 [95% CI: -3.8, -13.6], p = 0.001) and systolic BP (-3.6 [95% CI: -7.8, 0.5], p = 0.085). CONCLUSIONS The initiation of treatment with the CV-polypill in patients who previously received equally potent treatment with atorvastatin and ramipril was associated with a greater reduction in cLDL and systolic BP.

Abstract
The main objective of cardiovascular disease (CVD) prevention is to reduce morbidity and mortality. Despite recommendations on evidence-based pharmacological treatment and lifestyle changes, the control of CV risk factors such as hypertension or dyslipidaemia is not optimal. The use of a CV polypill, including guideline-recommended drugs, as a baseline therapy, may contribute to improving risk factors control either by improving the treatment adherence or by the synergistic effect of its components. The CNIC-Polypill is the first CV polypill approved in Europe as an effective strategy for secondary prevention, which contains acetylsalicylic acid, atorvastatin (in two optional doses), and ramipril (in three optional doses) in a single pill. The present practical clinical document aims to provide a guide for patient management after an acute coronary syndrome (ACS) or with chronic CVD (CCVD) with a strategy based on the CNIC-Polypill, also considering the need to add other therapies for a personalized treatment. The most suitable clinical scenarios for the CNIC-Polypill use are discussed: (a) in patients after an ACS at discharge, (b) in patients with CCVD (chronic coronary syndrome, stroke, or peripheral artery disease) with uncontrolled low-density lipoprotein cholesterol (LDL-c) and/or blood pressure levels and (c) in patients with CCVD with well-controlled risk factors to simplify treatment and reduce polypharmacy in the context of CCVD prevention.

Comparative efficacy of fixed-dose statin and antihypertensive agent combinations: A network meta-analysis of randomized controlled trials. Vascul Pharmacol 2021; 141:106900.

Abstract
BACKGROUND The concurrent administration of statins and antihypertensive agents has been associated with improved cardiovascular outcomes, although the optimal fixed-dose combination remains unclear. This meta-analysis aims to compare the blood pressure and lipid-lowering effects of various statin and antihypertensive drug combinations. METHODS PubMed, Scopus, Web of Science, CENTRAL and Clinicaltrials.gov were systematically searched from inception to 20 March 2021. Randomized controlled trials evaluating the effects of statin-antihypertensive agent combinations on systolic blood pressure or serum lipids were held eligible. A random-effects frequentist model was applied to provide estimates of mean difference of percentage change. RESULTS Overall, 18 studies were included, comprising 4450 patients. Compared to statin monotherapy no significant difference in the percentage change of low-density lipoprotein cholesterol was achieved by adding any antihypertensive agent. Compared to amlodipine monotherapy, the addition of moderate-intensity statin resulted in a significantly greater percentage reduction of systolic blood pressure (-2.22%, 95% confidence intervals: [-3.82 to -0.62]). Combined high-intensity statin and amlodipine lead to significant increase of high-density lipoprotein cholesterol (8.34%, 95% confidence intervals: [0.73 to 15.95]), while effective triglyceride reduction was achieved by adding amlodipine and telmisartan to high-intensity statin (-14.68%, 95% confidence intervals: [-28.48 to -0.89]). No significant difference of adverse effects was observed. CONCLUSION The present network meta-analysis suggests that the administration of fixed-dose combinations of statins and antihypertensive agents is safe and effective in reducing blood pressure and serum lipids. The optimal dosing strategy to prevent cardiovascular events remains to be determined.

Abstract
Aim: To evaluate the satisfaction, preferences and adherence of patients in secondary cardiovascular prevention treated with the Spanish National Cardiovascular Research Centre cardiovascular polypill compared with patients treated with the separate monocomponents. Methods: Observational, cross-sectional and multicenter study. Satisfaction was evaluated by the Treatment Satisfaction Questionnaire for Medication 9 items, adherence by the Morisky-Green questionnaire and ad-hoc questions were asked regarding patient preferences. Results: Polypill patients reported higher satisfaction than patients treated with the monocomponents (77.3 vs 71.2%; p < 0.0001). 72.8% of patients treated with the monocomponents would prefer to change to the polypill. Patients treated with the polypill had significantly higher adherence than patients treated with the monocomponents (57.7 vs 41.1%; p = 0.0027). Conclusion: Polypill patients show higher satisfaction and better adherence. Most patients receiving the monocomponents would prefer a polypill regime.

Abstract
PURPOSE OF REVIEW The recent publication of "Polypill for Cardiovascular Disease Prevention in an Underserved Population" study prompts a thoughtful review of known care disparities in cardiovascular disease management in underserved patients. A polypill approach as a population health solution to this complex problem should also be reviewed. RECENT FINDINGS Muñoz and colleagues open-label, randomized controlled trial of polypill vs. usual care was undertaken in minority patients at a federally qualified health center. The polypill, containing atorvastatin, amlodipine, losartan, and hydrochlorothiazide resulted in statistically significant improvements in systolic blood pressure and low-density lipoprotein levels (p = 0.003 and p < 0.001, respectively). The significant results of this study demonstrate the ability of a polypill approach to safely lower blood pressure, lipids, and thus estimated 10-year risk of CVD and are consistent with findings observed in previous literature. Uniquely, findings in a largely non-Hispanic Black patient population, offer an opportunity to examine this approach to combat important disparities in care in an underserved U.S. community. Further outcomes-based studies are warranted to explore the validity of these results and long-term safety of polypill treatment and are likely necessary prior to FDA approval and availability of a polypill product.

Abstract
BACKGROUND The use of the cardiovascular polypill, a fixed-dose combination treatment, is conceived to improve adherence. However, randomized controlled trials (RCTs) may overestimate it. Studies focusing on cerebrovascular disease and real-life efficacy compared with conventional treatment are lacking. METHODS This is a retrospective, hospital-based cohort study of acute ischaemic stroke patients who were prescribed a polypill (aspirin 100 mg, atorvastatin 20/40 mg, ramipril 2.5/5/10 mg) versus conventional treatment (aspirin 100 mg and other blood pressure/lipid-lowering agents) in secondary prevention (2017-2018). Clinical records were reviewed 90 days after discharge for stroke recurrence, vascular risk factor control, and safety. Adherence was assessed using the adapted Morisky-Green scale. RESULTS A total of 104 patients were included (61% male; mean age 69.7 ± 13.9 years); 54 were treated with the polypill and 50 with conventional treatment. No baseline differences in clinical or demographic variables were detected. No recurrences were registered in the polypill group, compared to 1 recurrence in the conventional treatment group. A significant reduction of systolic blood pressure (SBP) was achieved in the polypill group (12.1 mm Hg) compared to the conventional treatment group (6.8 mm Hg) (p = 0.002). No significant differences were detected regarding the goal of LDL cholesterol ≤70 mg/dL (41 vs. 44%). The adverse events were mild and their frequency was similar in the two groups (9 vs. 2%, ns). Adherence was similarly good in the two groups (93 vs. 88%, ns). Polypill group adherence was similar to that reported in a previous meta-analysis of RCTs (93 vs. 84%, ns). CONCLUSION In our experience, the cardiovascular polypill achieved a higher reduction in SBP levels and was well tolerated. Adherence was similar to that found in the previous literature, which is remarkable given the real-life setting of our study.

Abstract
The contribution of natural products (NPs) to cardiovascular medicine has been extensively documented, and many have been used for centuries. Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. Over the past 40 years, approximately 50% of newly developed cardiovascular drugs were based on NPs, suggesting that NPs provide essential skeletal structures for the discovery of novel medicines. After a period of lower productivity since the 1990s, NPs have recently regained scientific and commercial attention, leveraging the wealth of knowledge provided by multi-omics, combinatorial biosynthesis, synthetic biology, integrative pharmacology, analytical and computational technologies. In addition, as a crucial part of complementary and alternative medicine, Traditional Chinese Medicine has increasingly drawn attention as an important source of NPs for cardiovascular drug discovery. Given their structural diversity and biological activity NPs are one of the most valuable sources of drugs and drug leads. In this review, we briefly described the characteristics and classification of NPs in CVDs. Then, we provide an up to date summary on the therapeutic potential and the underlying mechanisms of action of NPs in CVDs, and the current view and future prospect of developing safer and more effective cardiovascular drugs based on NPs.

Abstract
Stroke is one of the leading causes of morbidity and mortality in the United States. While age-adjusted stroke mortality was falling, it has leveled off in recent years due in part to advances in medical technology, health care options, and population health interventions. In addition to adverse trends in stroke-related morbidity and mortality across the broader population, there are sociodemographic inequities in stroke risk. These challenges can be addressed by focusing on predicting and preventing modifiable upstream risk factors associated with stroke, but there is a need to develop a practical framework that health care organizations can use to accomplish this task across diverse settings. Accordingly, this article describes the efforts and vision of the multi-stakeholder Predict & Prevent Learning Collaborative of the Value in Healthcare Initiative, a collaboration of the American Heart Association and the Robert J. Margolis, MD, Center for Health Policy at Duke University. This article presents a framework of a potential upstream stroke prevention program with evidence-based implementation strategies for predicting, preventing, and managing stroke risk factors. It is meant to complement existing primary stroke prevention guidelines by identifying frontier strategies that can address gaps in knowledge or implementation. After considering a variety of upstream medical or behavioral risk factors, the group identified 2 risk factors with substantial direct links to stroke for focusing the framework: hypertension and atrial fibrillation. This article also highlights barriers to implementing program components into clinical practice and presents implementation strategies to overcome those barriers. A particular focus was identifying those strategies that could be implemented across many settings, especially lower-resource practices and community-based enterprises representing broad social, economic, and geographic diversity. The practical framework is designed to provide clinicians and health systems with effective upstream stroke prevention strategies that encourage scalability while allowing customization for their local context.

Abstract
Three-dimensional printing (3DP) has a significant impact on organ transplant, cosmetic surgery, surgical planning, prosthetics and other medical fields. Recently, 3 DP attracted the attention as a promising method for the production of small-scale drug production. The knowledge expansion about the population differences in metabolism and genetics grows the need for personalised medicine substantially. In personalised medicine, the patient receives a tailored dose and the release profile is based on his pharmacokinetics data. 3 DP is expected to be one of the leading solutions for the personalisation of the drug dispensing. This technology can fabricate a drug-device with complicated geometries and fillings to obtain the needed drug release profile. The extrusionbased 3 DP is the most explored method for investigating the feasibility of the technology to produce a novel dosage form with properties that are difficult to achieve using the conventional industrial methods. Extrusionbased 3 DP is divided into two techniques, the semi-solid extrusion (SSE) and the fused deposition modeling (FDM). This review aims to explain the extrusion principles behind the two techniques and discuss their capabilities to fabricate novel dosage forms. The advantages and limitations observed through the application of SSE and FDM for fabrication of drug dosage forms were discussed in this review. Further exploration and development are required to implement this technology in the healthcare frontline for more effective and personalised treatment.

Abstract
BACKGROUND AND AIMS The role of single pill combination therapy for stroke prevention remains to be established. We explored the perspectives of stroke survivors and healthcare professionals on single pill combination therapy for stroke prevention. METHODS We conducted focus groups involving stroke survivors and healthcare professionals. RESULTS We recruited six stroke survivors: four (67%) were female and mean age was 70 ± 12 years; and eight healthcare professionals (three Stroke Consultants, two Nurse Specialists, three General Practitioners). Improved adherence is the main perceived benefit of single pill combination therapy, although concerns exist surrounding less individualised care, unsuitability for use in the acute setting, reduced ability to titrate doses and difficulty identifying the cause of side effects. The clinical stability of patients, alongside single pill combination therapy efficacy, cost, side effect profile and evidence base for impact on risk factors and clinical outcomes are key factors influencing acceptability. Stroke survivors and healthcare professionals feel single pill combination therapy is most suitable for stable patients, although there is no evidence base for its use in this context. CONCLUSION Stroke healthcare professionals and stroke survivors are most amenable to using single pill combination therapy for stable patients, although its role in this context should be evaluated in studies with risk factor targets and clinical outcomes as endpoints.

Abstract
BACKGROUND Polypills, fixed-dose combinations of blood pressure-lowering drug(s), and statin, with or without aspirin, improve the use of these recommended drugs in patients with or at high risk of cardiovascular disease. However, in India, there has been poor uptake of polypills despite market availability. OBJECTIVES This study sought to assess availability and cost of polypills and explore barriers and facilitators to their use in the state of Andhra Pradesh in India. METHODS A mixed-methods study was conducted. Availability and cost of polypills as well as individual component drugs was assessed through a survey of pharmacies across urban, urban slum, and rural regions in state of Andhra Pradesh in India. In-depth interviews with stakeholders at each level of the health system explored barriers and facilitators to use of polypills. RESULTS Overall, 30 pharmacies were surveyed (10 in each of urban, urban slum, and rural region). In urban region, 2 pharmacies stocked polypills (without aspirin) costing 121 Indian rupees (INR) per 10 pills, and 1 other pharmacy stocked a polypill (with aspirin) costing 24 INR per 10 pills. All pharmacies stocked a wide range of component drugs as separate pills with combined cost of the cheapest angiotensin-converting enzyme inhibitor, statin, and aspirin INR 124 per 10 pills. Patients were willing to use polypills if prescribed by their doctor, and pharmacies were willing to stock polypills if there was market demand. For prescribers, key barriers included perceptions that current polypills contained outdated drugs and inadequate flexibility in prescribing. CONCLUSIONS In a market in which polypill use is licensed, their availability and use is very low. Lack of prescription of polypills was the predominant barrier to polypill use; therefore, making polypills with drugs that are more acceptable and at different available strengths, in conjunction with broader prescriber education and training, may improve their use.

Abstract
Hypertension and dyslipidaemia are modifiable risk factors associated with cardiovascular diseases (CVDs) and often require a complex therapeutic regimen. The administration of several medicines is commonly associated with poor levels of adherence among patients, to which World Health Organisation (WHO) proposed a fixed-dose combination unit (polypill) as a strategy to improve adherence. In this work, we demonstrate the fabrication of patient-specific polypills for the treatment of CVDs by fused deposition modelling (FDM) 3D printing and introduce a novel solution to meet critical quality attributes. The construction of poly(vinyl alcohol) (PVA)-based polypills containing four model drugs (lisinopril dihydrate, indapamide, rosuvastatin calcium and amlodipine besylate) was revealed for the first time. The impact of tablet architecture was explored using multi-layered and unimatrix structures. The novel approach of using distilled water as a 'temporary co-plasticiser' is reported and was found to significantly lower the extruding (90 °C) and 3D printing (150 °C) temperatures from 170 °C and 210 °C respectively, with consequent reduction in thermal stress to the chemicals. XRD indicated that lisinopril dihydrate and amlodipine besylate maintained their crystalline form while indapamide and rosuvastatin calcium were essentially in amorphous form in the PVA tablets. From the multilayer polypills, the release profile of each drug was dependent on its position in the multilayer. In addition to the multilayer architecture offering a higher flexibility in dose titration and a more adaptive solution to meet the expectations of patient-centred therapy, we identify that it also allows orchestrating the release of drugs of different physicochemical characteristics. Adopting such an approach opens up a pathway towards low-cost multidrug delivery systems such as tablets, stents or implants for wider range of globally approved actives.

Abstract
Polypharmacy is defined as the use of two or more drugs simultaneously. Cardiovascular drugs and antihypertensives are commonly prescribed for treatment of cardiovascular disease (CVD), especially in elderly patients. Recent studies in patients with a history of CVD demonstrated that the fixed-dose combination of cardiovascular drugs in a polypill retain their individual efficacy, safety, and tolerability, thus have the potential to improve medication adherence and multiple risk factor control, thereby improving patient outcomes in secondary cardiovascular prevention. Since the initial conception of the fixed-dose polypill, just over a decade ago, only six large randomized trials assessing the efficacy and safety of this innovative concept have been completed (one is still ongoing). The results demonstrate that the polypill therapy significantly improved adherence, lowered systolic blood pressure, and low-density lipoprotein cholesterol, compared with usual care, in patients at high risk for CVD, especially among those who were undertreated at baseline. Correspondingly, further studies showed that the strengths of the polypill include better adherence, equivalent or better risk factor control, and improved quality of life among polypill users, as compared with usual care. However, the long-term outcome of the polypill on CVD events and mortality are unavailable and are currently being studied in clinical trials.

Abstract
This review summarizes the potential for polypill therapies for stroke prevention. While a number of studies applying different approaches regarding polypill have been performed, none of them has had a focus on stroke as the main outcome. A combination pill containing drugs such as statins, diuretics, and other antihypertensives is currently available in various formats. Estimates focusing mostly on primary prevention show that using such a combination drug a reduction in the 5-year stroke incidence by 50% can be achieved - especially in low- and middle-income countries with a high prevalence of risk factors even among people at young ages. A combination of a large supporting population-wide program with a registry-based quality control is the most likely perspective and can be achieved within a reasonable time frame and potentially have significant influence in young stroke populations.

Abstract
The “long-life elixir” has long represented for humans a dream, a vanity's sin for remaining young and to long survive. Today, because of ageing population phenomenon, the research of antiageing interventions appears to be more important than ever, for preserving health in old age and retarding/or delaying the onset of age-related diseases. A hope is given by experimental data, which evidence the possibility of retarding ageing in animal models. In addition, it has been also demonstrated in animal life-extending studies not only the possibility of increasing longevity but also the ability to retard the onset of age-related diseases. Interestingly, this recent evidence is leading to promise of obtaining the same effects in humans and resulting in benefits for their health in old ages. In order to achieve this goal, different approaches have been used ranging from pharmacological targeting of ageing, basic biological assays, and big data analysis to the recent use of young blood, stem cells, cellular, genetic, and epigenetic reprogramming, or other techniques of regenerative medicine. However, only a little fraction of these approaches has the features for being tested in clinical applications. Here, new emerging molecules, drugs, and procedures will be described, by evidencing potential benefits and limitations.

Abstract
INTRODUCTION The elderly population (i.e. aged ≥ 65 years) is increasing worldwide. Ageing is associated with a higher incidence and prevalence of cardiovascular disease (CVD). Areas covered: The prevalence of CVD risk factors including type 2 diabetes mellitus, hypertension and dyslipidaemia also increases with advancing age, contributing to the higher absolute CVD risk observed in the elderly. The present narrative review comments on the associations of dyslipidaemia with CVD as well as the effects of lifestyle measures and lipid-lowering drugs on lipids and CVD risk with a special focus on the elderly population. Individual treatment goals and therapeutic options according to current guidelines are also reviewed. Finally, we discuss special characteristics of the elderly that may influence the efficacy and safety of drug therapy and should be considered before selection of hypolipidaemic pharmacotherapy. Expert commentary: There may be a greater CVD benefit in older patients following drug therapy compared with younger ones. Treatment goals and therapeutic options should be individualized according to current guidelines. Specific characteristics that may influence the efficacy and safety of drug therapy in the elderly should be considered in relation to dyslipidaemia treatment.
