Substandard drugs among five common antihypertensive generic medications

Substandard and falsified medicines in African pharmaceutical markets: A case study from Ethiopia

BACKGROUND

Substandard and falsified (SF) medicines are a global health problem. Their high prevalence is a threat to public health in low- and middle-income countries (LMICs). However, there are few street-level investigations of how this market works. This case study examines the supply and demand for SF medicines in Southern Ethiopia.

METHODS

A cross sectional qualitative design, using semi-structured interviews supplemented by participant observation, was adopted. Study participants were selected using purposive, convenience, and snowball sampling techniques. They included pharmacists, physicians, wholesalers, pharmacy owners, regulatory staff, law enforcement agents and the local community. A total of 43 interviews were conducted. The study used Actor-Network Theory (ANT) as an analytic framework.

RESULTS

The findings show that efforts to address the problem of SF medicines in Ethiopia struggle because of the lack of a clear framing of the issue and consensus on how it should be understood. The pharmaceutical market in Wolaita Zone, Southern Ethiopia is supplied with a wide variety of SF medicines from diverse sources. This complex supply chain emerges due to barriers to accessing essential medicines that are in demand. Control of SF medicines will require a range of interventions thoughtfully tailored to the local contexts and determinants of both supply and demand.

CONCLUSION

The evidence of confusion, ambiguity, and uncertainty in defining the problem of SF medicines suggest that more research and policy work is required to refine understanding of the issue, and of the local market conditions that join demand and supply for different medicines in Southern Ethiopia. These are likely to apply more widely in comparable contexts throughout sub-Saharan Africa. The current global policy emphasis on stricter regulation and enforcement alone does not adequately address the social and economic factors that collectively create and shape user demand that is met by SF medicines.

The pan-Canadian Tiered Pricing Framework and Chinese National Volume-Based Procurement: A comparative study using Donabedian's structure-process-outcome framework

Background

Generic drugs have been seen as a potentially powerful way to alleviate the financial burden on patients and health care systems. Two strategies for achieving rational prices of generic drugs are tiered pricing framework and pooled purchasing power. We compare the pan-Canadian Tiered Pricing Framework (TPF) and the Chinese National Volume-Based Procurement (NVBP) as comparators to explore the similarities and differences between the two mechanisms and summarise lessons for other jurisdictions.

Methods

This comparative study applies Donabedian's structure-process-outcome framework to systematically analyse the macro contexts, procedures, and long- and short-term results of each pricing mechanism, and the interactions between them.

Results

Structure: TPF is an upstream initiative aimed at lowering the prices of generic drugs and increasing coverage and price consistency. NVBP is a downstream national initiative prioritised for reducing drug prices to achieve value-based purchasing. Process: By associating the number of manufacturers with price cuts, TPF leaves the choice to manufacturers to decide if they want to enter a specific market. In contrast, the Chinese government determines NVBP list and has the authority to choose manufacturer(s) with the lowest price(s). TPF provides clear price information to potential suppliers with unclear order quantity. The NVBP drug price is determined by tendering, while procurement volume is clear and massive. Outcome: The effectiveness of TPF and NVBP is similar, with both achieving a 53% price cut. Both TPF and NVBP experienced efficiency improvement since their establishment, with 98 and 86 drugs priced per year. By comparing 60 drugs covered by both programmes, the NVBP price is 57% of that of the TPF counterpart on average (1.1 to 301.6%), by purchase power parity.

Conclusions

The tiered pricing scheme is feasible in regions with a stable and mature pharmaceutical market, typically seen in high-income countries, while tendering is more workable in low- and middle-income countries where the pharmaceutical market is weak and unstable. Experience in the two countries shows that a coordinated pricing mechanism involves many piecemeal interactive problems, which a sophisticated system with a robust long-range plan may address better.

Blood pressure changes during tenofovir-based antiretroviral therapy among people living with HIV in Lilongwe, Malawi: results from the prospective LighTen Cohort Study

BACKGROUND

Sub-Saharan Africa is one of the regions in the world with the highest numbers of uncontrolled hypertension as well as people living with HIV/AIDS (PLHIV). However, the association between hypertension and antiretroviral therapy is controversial.

METHODS

Participant demographics, medical history, laboratory values, WHO clinical stage, current medication, and anthropometric data were recorded at study entry and during study visits at 1, 3, 6 months, and every 6 months thereafter until month 36. Patients who stopped or changed their antiretroviral therapy (tenofovir, lamivudine, efavirenz) were censored on that day. Office blood pressure (BP) was categorized using ≥ 2 measurements on ≥ 2 occasions during the first three visits. Factors associated with systolic and mean BP were analyzed using bivariable and multivariable multilevel linear regression.

RESULTS

1,288 PLHIV (751 females, 58.3%) could be included and 832 completed the 36 months of observation. Weight gain and a higher BP level at study entry were associated with an increase in BP (p < 0.001), while female sex (p < 0.001), lower body weight at study entry (p < 0.001), and high glomerular filtration rate (p = 0.009) protected against a rise in BP. The rate of uncontrolled BP remained high (73.9% vs. 72.1%) and despite indication treatment, adjustments were realized in a minority of cases (13%).

CONCLUSION

Adherence to antihypertensive treatment and weight control should be addressed in patient education programs at centers caring for PLHIV in low-resources settings like Malawi. Together with intensified training of medical staff to overcome provider inertia, improved control rates of hypertension might eventually be achieved.

Stakeholder perspectives on the demand and supply factors driving substandard and falsified blood pressure lowering medications in Nigeria: a qualitative study

OBJECTIVES

Although substandard and falsified (SF) blood pressure (BP) lowering medications are a global problem, qualitative research exploring factors driving this in Nigeria has not been reported. This study provides information on factors driving demand for and supply of low-quality BP lowering medications in Nigeria and potential strategies to address these factors.

METHODS

This was a cross-sectional qualitative study. Between August 2020 and September 2020, we conducted 11 in-depth interviews and 7 focus group discussions with administrators of health facilities, major manufacturers and distributors of BP lowering medications, pharmacists, drug regulators, patients and primary care physicians purposively sampled from the Federal Capital Territory, Nigeria. Data were analysed using directed content analysis, with the aid of Dedoose.

RESULTS

We found that demand for SF BP lowering medications in Nigeria was driven by high out-of-pocket expenditure and stockouts of quality-assured BP lowering medications. Supply of low-quality BP lowering medications was driven by limited in-country manufacturing capacity, non-adherence to good manufacturing and distribution practices, under-resourced drug regulatory systems, ineffective healthcare facility operations, poor distribution practices, limited number of trained pharmacists and the COVID-19 pandemic which led to stockouts. Central medicine store procurement procedures, active pharmaceutical ingredient quality check and availability of trained pharmacists were existing strategies perceived to lower the risk of supply and demand of SF BP lowering medications.

CONCLUSION

Our findings suggest that demand for and supply of SF BP lowering medications in Nigeria are driven by multi-level, interrelated factors. Multi-pronged strategies need to target stakeholders and systems involved in drug production, distribution, prescription, consumption, regulation and pricing.

The impact of COVID-19 on patients with neurological disorders and their access to healthcare in Africa: A review of the literature

INTRODUCTION

The coronavirus disease 2019 (COVID-19) pandemic has hampered the progress of neurological healthcare services for patients across Africa. Before the pandemic, access to these services was already limited due to elevated treatment costs among uninsured individuals, shortage of medicines, equipment, and qualified personnel, immense distance between residing areas and neurological facilities, and a limited understanding of neurological diseases and their presentation by both the health workers and the African population.

METHODOLOGY

The databases PubMed, Google Scholar, Science Direct, and the National Library of Medicine were searched for literature. All articles on neurological disorders in Africa were considered.

AIM

This review article explores the challenges of providing the best services for patients suffering from neurological disorders in Africa amid the COVID-19 pandemic and provides evidence-based recommendations.

RESULTS

As Africa's governments made more resources available to support patients affected by COVID-19, neurological care received less priority and the capacity and competency to treat patients with neurological disorders thus suffered substantially. Both short-term and long-term strategies are needed to improve the quality of neurological services after the pandemic in the region.

CONCLUSION

To strengthen Africa's neurological services capability during and after the COVID-19 pandemic, African governments must ensure appropriate healthcare resource allocation, perform neurology management training, and increase health security measures in medication supply. Long-term strategies include incorporating responsible finance and resource procurement and advancement of tele-neurology. International collaboration is essential to promote the sustainable improvement of neurological services in Africa.

Falsified and substandard medicines trafficking: A wakeup call for the African continent

While great effort is being placed on reducing disease burdens in Africa, the circulation of falsified and substandard medicines in the continent are reversing the hard-won gains. This commentary provides insights on the high (and increasing) burden, impact and threat that falsified and substandard medicines pose to the region's development. The proposed recommendations, such as a coherent multi-sectorial and government-led strategy, call for a fundamental rethink of approaches towards strong regulations, policies, legislations, community-based approaches, collaborations and investments, which all must be scaled up before this the situation gets out of control. These recommendations are of paramount importance and have the potential to ensure access to genuine medicines and also to avert therapeutic failure and intoxication from dangerous substances. In addition, there will be added benefits to the economic, social, health and well-being of the region. Concerted efforts towards medicine regulations have enormous potential to contribute towards averting many preventable deaths and reducing disease burden in the region. A paradigm shift is necessary to ensure quality medicines reach patients at community and healthcare facilities to prevent this silent epidemic in Africa.

A simple six-step guide to National-Scale Hypertension Control Program implementation

Hypertension is the leading single preventable risk factor for death worldwide, and most of the disease burden attributed to hypertension weighs on low-and middle-income countries. Effective large-scale public health hypertension control programs are needed to control hypertension globally. National programs can follow six important steps to launch a successful national-scale hypertension control program: establish an administrative structure and survey current resources, select a standard hypertension treatment protocol, ensure supply of medication and blood pressure devices, train health care workers to measure blood pressure and control hypertension, implement an information system for monitoring patients and the program overall, and enroll and monitor patients with phased program expansion. Resolve to Save Lives, an initiative of global public health organization Vital Strategies, and its partners organized these six key steps and materials into a structured, stepwise guide to establish best practices in hypertension program design, launch, maintenance, and scale-up.

24-h-Ambulatory Blood Pressure Monitoring in Sub-Saharan Africa: Hypertension Phenotypes and Dipping Patterns in Malawian HIV+ Patients on Antiretroviral Therapy

Background:

Cardiovascular disease and especially hypertension are a growing problem among people living with HIV (PLHIV) on antiretroviral therapy (ART) in sub-Saharan Africa.

Objectives:

As robust data on hypertension phenotypes associated with distinct cardiovascular risks among PLHIV are limited, we aimed to assess the frequency of white-coat (WCH), masked (MH) hypertension, and blood pressure dipping-patterns in a group of Malawian PLHIV.

Methods:

As part of the prospective Lighthouse-Tenofovir-Cohort-Study, we analyzed clinical, laboratory and 24-h-ambulatory blood pressure monitoring (ABPM) data of PLHIV from urban Lilongwe with treated or untreated hypertension or raised office blood pressure (OBP) during routine study-visits.

Results:

118 PLHIV were included and data of 117 participants could be analyzed. Twenty–four-hour ABPM normotension was found in a total of 73 PLHIV including 14/37 on antihypertensive treatment (37.8%). Using strict definitions, i.e. normal OBP plus normal mean BP for all periods of ABPM, controlled hypertension was found in only 4/37 (10.8%) PLHIV on antihypertensive treatment while true normotension was observed in 10/24 untreated patients (41.7%) with previously diagnosed hypertension and 22/56 patients (39.3%) without a medical history of hypertension. WCH with normal BP during all periods of 24-h-ABPM was identified in 12/64 OBP-hypertensive PLHIV (18.8%), primarily in patients with grade 1 hypertension (11/41 patients; 26.8%). MH was found in 17/53 PLHIV with OBP-normotension (32.1%), predominantly in patients with high normal BP (11/20 patients; 55%). The estimated glomerular filtration rate tended to be lower in MH compared to strictly defined normotensive PLHIV (92.0±20.4 vs. 104.8±15.7 ml/min/m²). 64.1 percent of PLHIV (59.5% with 24-h hypertension and 66.7% with 24-h normotension) had abnormal systolic dipping.

Conclusion:

The high prevalence of WCH and MH with signs of early renal end-organ damage and an abnormal dipping in approximately 2/3 of PLHIV warrants further investigation as these factors may contribute to the increased cardiovascular risk in PLHIV in resource-limited settings like Malawi.

Quality of timolol eye drops marketed in Kinshasa, Democratic Republic of the Congo

OBJECTIVE

To assess the quality of timolol eye drops sold in Kinshasa, Democratic Republic of Congo (DRC).

METHODS

Seven samples of timolol maleate 0.5% were purchased over the counter in seven randomly selected public pharmacies in 3 neighborhoods in Kinshasa. They were submitted to a quality assessment that included visual inspection, spectrophotometry, high performance liquid chromatography (HPLC), and bacteriologic assessment.

RESULTS

The samples came from France (n=2), India (n=2) and DRC (n=3). Overall, 3 (2 from India and 1 from the DRC) of the 7 samples, or 3 out of the 5 from developing countries, showed various abnormalities consistent with substandard drugs. One sample (India) demonstrated an incorrect pH, while 3 (2 from India and one from the DRC) had lower than stated volumes as well as lower than required concentrations of the active pharmaceutical ingredient. In addition, one sample from the DRC was bacteriologically contaminated.

CONCLUSION

These results suggest that some timolol maleate eye drops from Congolese and Indian manufacturers sold in Kinshasa are of substandard quality. This may reflect deficiencies in the manufacturers and local authorities charged with regulation of the quality control and sale of pharmaceuticals. Passing a visual inspection does not necessarily indicate that a drug is not substandard. Analytical chemistry testing and bacteriologic analysis are required to determine with certainty the quality of the drug.

Pandemics and Burden of Stroke and Epilepsy in Sub-Saharan Africa: Experience from a Longstanding Health Programme

Eighty percent of people with stroke live in low- to middle-income nations, particularly in sub-Saharan Africa (SSA) where stroke has increased by more than 100% in the last decades. More than one-third of all epilepsy−related deaths occur in SSA. HIV infection is a risk factor for neurological disorders, including stroke and epilepsy. The vast majority of the 38 million people living with HIV/AIDS are in SSA, and the burden of neurological disorders in SSA parallels that of HIV/AIDS. Local healthcare systems are weak. Many standalone HIV health centres have become a platform with combined treatment for both HIV and noncommunicable diseases (NCDs), as advised by the United Nations. The COVID-19 pandemic is overwhelming the fragile health systems in SSA, and it is feared it will provoke an upsurge of excess deaths due to the disruption of care for chronic diseases such as HIV, TB, hypertension, diabetes, and cerebrovascular disorders. Disease Relief through Excellent and Advanced Means (DREAM) is a health programme active since 2002 to prevent and treat HIV/AIDS and related disorders in 10 SSA countries. DREAM is scaling up management of NCDs, including neurologic disorders such as stroke and epilepsy. We described challenges and solutions to address disruption and excess deaths from these diseases during the ongoing COVID-19 pandemic.

In vitro Comparative Quality Assessment of Different Brands of Furosemide Tablets Marketed in Northwest Ethiopia

Background

The use of ineffective and poor quality drugs endangers therapeutic treatment and may lead to treatment failure. For desired therapeutic effect, drugs should contain the appropriate amount of active pharmaceutical ingredient and the required physical characteristics.

Aim

The aim of this study was to evaluate quality as well as physicochemical bioequivalence of different brands of furosemide tablets marketed in Bahir Dar, Northwest Ethiopia.

Methods

Five different brands of furosemide tablets were purchased from community pharmacies in Bahir Dar city, Northwest Ethiopia. The quality control parameters of furosemide tablets were determined by identification, weight variation, disintegration, assay and dissolution tests and the results were compared with USP and BP pharmacopoeial standards. Difference (f1) and similarity (f2) factors were calculated to assess in vitro bioequivalence requirements.

Results

Identification test results revealed that all samples contained the stated active pharmaceutical ingredients. The results of weight variation tests indicated that all samples complied with USP specification limits. The active pharmaceutical ingredients quantitative assay showed that all the brands of furosemide tablets were between the 90% and 105% limit of label claim. Similarly, all samples fulfilled disintegration time (i.e., ≤30 min) and dissolution tolerance limits (i.e., Q ≥80% at 60 min). Hence, none of the samples were found to be counterfeit and/or substandard. Difference factor (f1) values were <15 and similarity factor (f2) values were >50 for all the tested brands of furosemide tablets.

Conclusion

This study revealed that all the furosemide brands met the quality specification of weight variation, hardness, friability, dissolution, disintegration and assay. The study also indicated similarity in the dissolution profile of the brands of furosemide tablets with the innovator product. Hence, all of these generic brands could be substituted with the innovator product in clinical practice.

Post hoc study to investigate the potential causes of poor quality of cardiovascular medicines collected in sub-Saharan countries

OBJECTIVES

The incidence of cardiovascular diseases is increasing and there is a growing need to provide access to quality cardio drugs in Africa. In the SEVEN study, we analysed 1530 cardiovascular drug samples randomly collected from 10 African countries. By that time, of the seven drugs products analysed, only those containing amlodipine and captopril had very low assay values with active substance contents that could be less than 75% of those expected. In this article we investigate complementary aspects of the amlodipine and captopril samples so to explain the previously observed low assays for these two drugs.

DESIGN

Post hoc analysis of the captopril and amlodipine drugs samples and their packages collected in the context of the SEVEN study.

SETTING

10 countries were concerned: Benin, Burkina Faso, Congo, Democratic Republic of the Congo, Guinea, Côte d'Ivoire, Mauritania, Niger, Senegal and Togo.

PARTICIPANTS

Local scientists and hospital practitioners collected the drug samples in the 10 African countries.

OUTCOME MEASURES

The drug amount and the relative amounts of drug impurities, as well as the main compounds of the drugs packaging, were analysed.

RESULTS

Identification of the blister packaging of the samples led to separate both amlodipine and captopril drug samples in two groups. Mann Whitney's bilateral test showed a significant difference (p<0.0001) between the median value of the captopril dosage when tablets are packaged in blisters providing higher protection to humidity (n=105) as opposed to the tablets packaged in blisters providing lower humidity protection (n=130).

CONCLUSION

Based on these results, particular attention should be paid to the materials and types of packaging used in order to minimise the lack of control over the exposures and drug circuits present in these different countries.

Poor adherence to medication and salt restriction as a barrier to reaching blood pressure control in patients with hypertension: Cross-sectional study from 12 sub-Saharan countries

BACKGROUND

Sub-Saharan Africa is experiencing a rising burden of hypertension. Antihypertensive medications and diet are the cornerstone of effective hypertension control.

AIMS

To assess adherence to medication and salt restriction in 12 sub-Saharan countries, and to study the relationship between adherence and blood pressure control in patients with hypertension.

METHODS

We conducted a cross-sectional survey in urban clinics in twelve sub-Saharan countries. Data were collected on demographics, treatment and adequacy of blood pressure control in patients with hypertension attending the clinics. Adherence was assessed by questionnaires completed by the patients. Hypertension grades were defined according to European Society of Cardiology guidelines. Association between adherence and blood pressure control was investigated using multilevel logistic regression analysis, adjusting for age, sex and country.

RESULTS

Among the 2198 patients, 77.4% had uncontrolled blood pressure, 34.0% were poorly adherent to salt restriction, 64.4% were poorly adherent to medication and 24.6% were poorly adherent to both. Poor adherence to salt restriction (odds ratio [OR] 1.33, 95% confidence interval [CI] 1.03-1.72), medication (OR 1.56, 95% CI 1.25-1.93) or both (OR 1.91 1.39-2.66) was related to uncontrolled blood pressure. Moreover, poor adherence to both medication and salt restriction was related to a 1.52-fold (95% CI 1.04-2.22), 1.8-fold (95% CI 1.22-2.65) and 3.08-fold (95% CI 2.02-4.69) increased likelihood of hypertension grade 1, 2 and 3, respectively.

CONCLUSIONS

High levels of poor adherence to salt restriction and medication were noted in this urban sub-Saharan study; both were significantly associated with uncontrolled blood pressure, representing major opportunities for intervention to improve hypertension control in sub-Saharan Africa.

Equivalence in Active Pharmaceutical Ingredient of Generic Antihypertensive Medicines Available in Nigeria (EQUIMEDS): A Case for Further Surveillance

BACKGROUND

Widespread access to good quality antihypertensive medicines is a critical component for reducing premature cardiovascular disease (CVD) mortality. Poor-quality medicines pose serious health concerns; however, there remains a knowledge gap about the quality of cardiovascular medicines available in low- and middle-income countries.

OBJECTIVES

The aim of this study was to determine the quality of generic antihypertensive medicines available in the retail market of a developing country.

METHODS

Samples of the 2 most commonly prescribed classes of antihypertensive medicines were collected from 3 states in 3 different geopolitical zones in Nigeria following a semirandom sampling framework. Medicine samples were purchased by mystery shoppers from 22 pharmacy outlets from 6 local government areas across the 3 states. Medicine quality was determined by measuring the amount of stated active pharmaceutical ingredient using high-performance liquid chromatography with photodiode array detection and classified according to their compliance to the specified pharmacopeia tolerance limits for each antihypertensive drug.

RESULTS

Amlodipine and lisinopril were identified as the most commonly prescribed antihypertensive drugs in Nigeria. In total, 361 samples from 22 pharmacies were collected and tested. In total, 24.6% of amlodipine and 31.9% of lisinopril samples were of substandard quality and significantly more samples purchased in rural (59 of 161, 36.7%) compared with urban (32 of 200, 16%) outlets were found to be of substandard quality (p < 0.001). No falsified samples of either amlodipine or lisinopril were detected. There was large variation in price paid for the antihypertensive medicines (range ₦150 to ₦9,750). Of the 24 pharmacy outlets surveyed, 46% stated that patients did not always require a prescription and 21% had previously reported a medicine as falsified or substandard.

CONCLUSIONS

More than one-quarter of some commonly prescribed antihypertensive medicines available in Nigeria may be of substandard quality. Enhanced quality assurance processes in low- and middle-income countries, such as Nigeria, are needed to support optimum management.

Factors associated with poor adherence to medication among hypertensive patients in twelve low and middle income Sub-Saharan countries

Introduction

Over the past few decades, the prevalence of hypertension has dramatically increased in Sub-Saharan Africa. Poor adherence has been identified as a major cause of failure to control hypertension. Scarce data are available in Africa.

Aims

We assessed adherence to medication and identified socioeconomics, clinical and treatment factors associated with low adherence among hypertensive patients in 12 sub-Saharan African countries.

Method

We conducted a cross-sectional survey in urban clinics of both low and middle income countries. Data were collected by physicians on demographics, treatment and clinical data among hypertensive patients attending the clinics. Adherence was assessed by questionnaires completed by the patients. Factors associated with low adherence were investigated using logistic regression with a random effect on countries.

Results

There were 2198 individuals from 12 countries enrolled in the study. Overall, 678 (30.8%), 738 (33.6%), 782 (35.6%) participants had respectively low, medium and high adherence to antihypertensive medication. Multivariate analysis showed that the use of traditional medicine (OR: 2.28, 95%CI [1.79–2.90]) and individual wealth index (low vs. high wealth: OR: 1.86, 95%CI [1.35–2.56] and middle vs. high wealth: OR: 1.42, 95%CI [1.11–1.81]) were significantly and independently associated with poor adherence to medication. In stratified analysis, these differences in adherence to medication according to individual wealth index were observed in low-income countries (p<0.001) but not in middle-income countries (p = 0.17). In addition, 26.5% of the patients admitted having stopped their treatment due to financial reasons and this proportion was 4 fold higher in the lowest than highest wealth group (47.8% vs 11.4%) (p<0.001).

Conclusion

This study revealed the high frequency of poor adherence in African patients and the associated factors. These findings should be useful for tailoring future programs to tackle hypertension in low income countries that are better adapted to patients, with a potential associated enhancement of their effectiveness.

Hypertension in Developing Countries: A Major Challenge for the Future

PURPOSE OF REVIEW

Outline recent epidemiologic data regarding hypertension in developing countries, distinguish differences from developed countries, and identify challenges in management and future perspectives.

RECENT FINDINGS

Increased sugar intake, air and noise pollution, and low birth weight are emerging hypertension risk factors. The major challenges in management are difficulties in accurate diagnosis of hypertension and adequate blood pressure control. In contrast to developed countries, hypertension prevalence rates are on the rise in developing countries with no improvement in awareness or control rates. The increasing burden of hypertension is largely attributable to behavioral factors, urbanization, unhealthy diet, obesity, social stress, and inactivity. Health authorities, medical societies, and drug industry can collaborate to improve hypertension control through education programs, public awareness campaigns, legislation to limit salt intake, encourage generic drugs, development and dissemination of national guidelines, and involving nurses and pharmacists in hypertension management. More epidemiologic data are needed in the future to identify reasons behind increased prevalence and poor blood pressure control and examine trends in prevalence, awareness, treatment, and control. National programs for better hypertension control based on local culture, economic characteristics, and available resources in the population are needed. The role of new tools for hypertension management should be tested in developing world.
