  Abstract 

Objective: Iranian healthcare system cost has been remarkably growing during the recent decades. Drug shortages and the economic effects of the sanctions have also exposed the pitfalls and shortcomings of the pharmaceutical system. Moreover, the pharmaceutical system is a major expenditure source for the health system. Pharmaceutical market trend analysis serves as a reliable tool to gather and analyze market and consumption data to take account of the past policies and forecast the future of the market and disease trends. Methods: The present work tries to quantitatively describe and analyze past 17 years of Iranian pharmaceutical market sales data from 2000 to 2016. The anatomical therapeutic chemical-classified drug utilization data obtained from the Iranian Food and Drug Administration were used to analyze the market trends for each therapeutic class and categorize them. Findings: The size of Iranian pharmaceutical market has grown dramatically during the last 5 years reaching to $5.183 billion in 2016 from $3.847 billion in 2011 with a compound annual growth rate of 6.14%. Antidiabetics and antineoplastic agents were one of the most prominent market growth drivers. Introduction of new drug molecules to the market has also contributed to the trend. However, the noncommunicable diseases are gaining momentum in the national disease burden. Conclusion: The market growth necessitates policies to prevent the overwhelming cost burden on the healthcare system which in turn requires well-informed decision-making. Pharmaceutical market trend analysis tries to supply the evidence feed for informed policy-making to forecast, prioritize, and contain the cost burden imposed on the healthcare system by the pharmaceutical sector.

  Introduction Top


Iran is the second most populated country in the Middle East and North Africa region after Egypt, with 80.28 million population in 2016, also being the second largest economy in this region after Saudi Arabia with an estimated gross domestic product (GDP) of $412.2 billion in 2016.[1]

Nearly 6.9% of the GDP has been spent on the healthcare in 2014 that is close to Tunisia (7.0%) and Lebanon (6.4%).[1],[2] The public sector accounted for 41% of total healthcare expenditure while the private sector accounted for 59% of health expenditure. The health expenditure per capita (in current US$) is US$351 which is close to that of Jordan (US$359) and Algeria (US$359). About 12.7% of health expenditure is allocated to pharmaceutical sector.[1],[3]

The challenge of growing health sector expenditure on medicines is a top priority for some developing countries to tackle. The counteracting interests of players in the pharmaceutical sector embedded in a larger and highly regulated healthcare market make the implementation of a range of cost containment policies a rational choice.[4]

Iranian pharmaceutical market has undergone a couple of significant ups and downs in the past two decades, for example, governmental financial support policies, national currency devaluation, extensive drug shortages, sanctions, and healthcare system reform. However, despite political pressures and inevitable economic liberation of the pharmaceutical industry to domestic private sector and also multinational entities, the domestic market is protected from globalization and competition forces by tariff and regulatory measures. Although it is not believed to sustain for long, there is still a predominant governmental control over the market. Drug shortages and market forces have worked together to shape the pharmaceutical market evolution which makes it an incredible case study for the transforming markets in developing countries.[4],[5]

Trend analysis study on the pharmaceutical market contributes significantly to our understanding of drug consumption dynamics, communicable and noncommunicable disease (NCDs) epidemiological variations which shape the foundation of the pharmacoepidemiologic studies. However, to the best our knowledge, there is a wide knowledge gap in this field that could be overcome with such studies. Consumption trend analysis helps decipher the time variability of the diseases in the country, employing the drug consumption as a surrogate variable for the disease prevalence.[6]

Therefore, these studies could assist health and pharmaceutical policymakers to optimally draw a picture of the future, prioritize, and allocate resources accordingly by providing them with market dynamics through statistical inference.

The current study updates and expands the realm of the trend analysis of the Iranian pharmaceutical market and details the medicines use in Iran 2000–2016. It tries to figure out if there has been any significant change in the therapeutic classes during the past 17 years. Thereafter, we would consider forecasting the future of therapeutic classes in the next 5 years based on the consumption data.


  Methods Top


This research is a descriptive, cross-sectional study that tries to quantitatively investigate the past 17 years of Iranian pharmaceutical market from 2000 to 2016, adjusted by the time series data availability in each case. This study is performed pursuant to and as a complimentary update of another study done in 2013.[4]

The drug utilization data classified based on the anatomical therapeutic chemical (ATC) classification methodology that is developed and maintained by the World Health Organization (WHO) Collaborating Center for Drug Statistics Methodology were obtained from the Iranian Food and Drugs Administration (IFDA).[7] This classification methodology was adopted in this study to serve as a tool for the drug utilization research. ATC codes classify active pharmaceutical substances according to their main indication of use and chemical characteristics. The classification consists of five levels with anatomical main group and therapeutic subgroup as the first and second levels and specific active substances as the fifth level.[8]

In this study about 3300 different dosage forms of around 1400 drug molecules available in the Iran drug list (IDL)were classified based on their respective ATC codes.

Sales values are presented in US Dollar following the official exchange rate released by the Central Bank of Iran which is the official currency exchange rate used in the pharmaceutical industry.[9]

Microsoft Excel was used to analyze the sales data. However, the accuracy of the consumption data remains under scrutiny since the accessible data are merely based on the sale values by the distributors to retail pharmacies and might not utterly correlate with the consumption. To the best of our knowledge, a realistic consumption data source is lacking, and therefore, the assumption was that the distributors to retail pharmacies' sale values are an acceptable surrogate for consumption and utilization. In addition, most available articles published on the drug consumption have also supposed a relatively similar approach for the consumption approximation to explore the real consumption rate in the patient population. Six different statistical forecasting models including linear, exponential, polynomial (order 2 and order 3), logarithmic, moving average, and compound annual growth rate (CAGR) for the periods of the last 3, 5, or 10 years ending at 2016 have been employed in this study. A panel of eight pharmaceutical market experts selected the appropriate pattern of medicine consumption for each ATC group to find the best retrospective and futuristic data fitting and forecast approach through to 2022. The expert panel members included business, marketing, and executive managers of some major pharmaceutical companies, policymakers, and pharmacoeconomics professors, who had actively participated in the pharmaceutical market practices in the past 10 years, based on a purposive sampling until the attainment of saturation in the ideas. However, for some participants, the expertise may have some overlap because of their diversity of involvements. They employed their experience and publications on the Iranian pharmaceutical market to attain a reliable estimation method based on specific dynamics and behavior of various market segments. Having selected the best forecasting model, the expert panel and the researchers tried to rank the classes based on their attractiveness. Three different criteria were selected for the demonstration of results which included actual CAGR (2011–2016), forecasted CAGR (2017–2022), and average market share (2014–2016).



This attractivity ranking is contemplated as a market attractivity driving force to help predict the trends of each therapeutic class, assuming that the most attractive classes will take the market growth lead.

The Iranian pharmaceutical market size has grown dramatically during the last 5 years. According to the annual statistical datasheet published by the IFDA under the Ministry of Health and Medical Education, the market size has grown from $3.847 billion in 2011 to $5.183 billion in 2016, showing a steep annual growth rate during the last 5 years (CAGR2011–2016 =6.14%).

Financially, the market share of the private sector (private pharmaceutical importer and manufacturer) has increased from 43% in 2000 to 67% in 2016 against the public sector. The market share of the domestic production had shrunk from 85% in 2000 to 60% in 2010 and increased back again to 70% in 2016.

During the recent 5 years (2012–2016), 144 new molecular entities in 461 different stock keeping units have been added into the IDL. Among the 14 anatomical main groups, anti-infective medicines for systemic use, alimentary tract and metabolism (including drugs used in diabetes), antineoplastic and immunomodulating agents, nervous system, and blood and blood-forming organs have contributed the most with 25, 22, 18, 15, and 12 new molecules, respectively.

Alimentary tract and metabolism (including drugs used in diabetes), antineoplastic and immunomodulating agents, blood and blood-forming organs, nervous system, and anti-infectives for systemic use were the main growth drivers of the Iranian pharmaceutical market (2011–2016) contributing $371, $237, $218, $188, and $95 million to the increase in overall sales, respectively [Figure 1] and [Table 1].

  Discussion Top


Trend analysis of the Iranian pharmaceutical market shows that the market is growing significantly and its CAGR is estimated to be twice that of the global market.[2],[10],[11],[12] The market share of antineoplastic and immunomodulating agents, alimentary tract and metabolism medicines (including drugs used in diabetes), blood and blood-forming organs, and nervous system medicines may expand quickly and their cumulative market share will reach 60% from 54% of the whole market. The main drivers of this growth will be:

  1. Monoclonal antibodies and protein kinase inhibitors from the antineoplastic agents therapeutic subgroup
  2. Tumor-necrosis-factor alpha inhibitors from the immunosuppressants therapeutic subgroup of the antineoplastic and immunomodulating agents ATC group
  3. Insulins and analogs (especially novel insulin preparations) and new classes of oral blood-glucose-lowering drugs from the drugs used in diabetes therapeutic subgroup of alimentary tract and metabolism ATC group
  4. Direct thrombin inhibitors and enzymes from the antithrombotic agent's therapeutic subgroup of the blood and blood-forming organs ATC group
  5. Newly introduced classes in the nervous system ATC group.


The observed trend in the market segments implies certain underlying market forces. Alimentary tract and metabolism (including drugs used in diabetes) have been the largest and the fastest-growing ATC group in type 1 category. This observation coincides with the vast public health awareness and introduction of new generic antidiabetics.[13],[14],[15]

“Antineoplastic and immunomodulating agents” is a specific group in the sense, they have been a major target of the price control policies enforced by the IFDA which generally works toward market suppression by preventing prices to ratchet up; however, it has been the fastest-growing group in this period with similar growth forecast. This forecast is in line with the global projection that this class would be the leading ATC group in terms of growth with the CAGR2017–2022 =12.7%.[16] Blood and blood-forming organs ATC group represents another policy target. Noteworthy, some of the hemophilic products were removed from the governmental subsidy list, which has affected the market value by the pursuant price increase.[17] Cardiovascular system is expected to be the second fastest-growing group in 2017–2022. According to the WHO, in 2014, cardiovascular diseases were the leading cause of death in Iran and account for an estimated 46% of all NCDs deaths.[18] The forecasts also mention the growing role of cardiovascular diseases in the health system costs.[19]

Another expected trend relates to the anti-infectives for systemic use that has one of the lowest annual growth rates and forecasted growth. This might show the shift of the burden of diseases in Iran from communicable diseases to NCDs in the future and efforts by the Ministry of Health to promote rational use of drugs specifically antibiotics and glucocorticoids.[20] In addition, musculoskeletal system ATC group has been a very small group which might be related to the scarcity of new generic formulations and dosage forms. However, recent registration of some new products in the IDL may prompt its market to expand in the midterm.[21],[22]

Antiparasitic products, insecticides, and repellents therapeutic class has experienced a diminishing market share during the past years. This trend is consistent with the fact that the prevalence of parasitic and insect-borne diseases has decreased with the enforcement of the public hygiene measures through environmental and health protection programs which constitute a national initiative along with the social determinants of health program.[23]

Genitourinary system and sex hormones have been one of the smallest main groups with low annual growth rate but its forecast higher than the market average. This represents the diminished use of oral contraceptive pills due to governmental pro-growth population policy. However, new urological generic products have been launched and may affect size of the market in the future. On the other hand, the population growth policies have not been stable and population growth promoting programs have not been enforced fully in the last few years.[24]

However, not all the trends necessarily comply with the expectations. For example, respiratory system drugs annual growth rate has been lower than the market average which could imply that the prevalence of respiratory tract diseases had remained steady while the possibility of the market expansion due to active and passive smoking and air pollution crisis in the major cities has faded away.[25]

The statistical datasheet that was the basis for this study contains sales data for the past 17 years originating from sales by the distribution companies to the retail pharmacies. Counterparts of such database can hardly be found in the developing countries. It is published under supervision of the IFDA and contains the sales data by value and numbers based on generic names, suppliers, and distribution companies. However, this database faces distinct shortcomings including data for some years are faulty, it just shows the distributor-to-pharmacy sales and not real consumption, and the data do not comprise sales data for the preparations which Ministry of Health purchases and distributes to the end users such as vaccines and antiretrovirals.

As the results show, the Iranian pharmaceutical market has experienced a high growth rate during past one and a half decade. Accordingly, the analysis of the trends can explain a significant portion of the market variability which is backed by the epidemiological evidence. The market growth signals the need for policies to implement evidence-based medicine, sustainable price control policies, optimized cost reimbursement, and efficient and timely diagnostic and preventive measures for NCDs as evidenced by the epidemiologic shift in burden of diseases.[26],[27] With such policies and plan of action in place, the pharmaceutical sector expenditure imposed on the healthcare system could be contained.[28] In fact, pharmaceutical market trend analysis provides the feed for informed policy-making and benchmark studies. As the results denote, it could be advisable to investigate each ATC group with further details to find the trend and underlying growth drivers. Consequently, further investigation of the therapeutic groups can help understand the detailed underlying market dynamics for each market segment so that the policies are adjusted according to the factual evidence.
