Factors Affecting Consumers' Purchase Decision of Over-The-Counter (OTC) Medicines: Empirical Evidences From Community Pharmacies in Ethiopia
Factors Affecting Consumers' Purchase Decision of Over-The-Counter (OTC) Medicines: Empirical Evidences From Community Pharmacies in Ethiopia
Abstract
Purpose: the aim of this study was to examine factors affecting consumers’ purchase decision of over-the-
counter (OTC) medicines from community pharmacies in Ethiopia.
Design/methodology/approach: A quantitative research design was used to test the effect of various factors on
consumer purchase decision of OTC medicines. Descriptive and explanatory research approaches were used to
describe and investigate the relationship between dependent and independent variables. Both primary and
secondary data were collected using self-administered questionnaire and Statistical Package for the Social
Sciences (SPSS) version 23 was used to analyze the data.
Findings: the researchers found that, pharmacist’s recommendation, price, and country of origin of OTC
medicines have positive and significant effect on consumers’ purchase decision of OTC medicines. Even though,
previous experience and families' and friends' recommendation have positive effect on consumers’ purchase
decision of OTC medicines, is not statistically significant.
Originality/value: Few studies have been conducted on OTC medicines from pharmacy practice perspective and
their result showed that there are significant numbers of consumers using OTC medicines. In the best of authors’
knowledge, however; no research has been conducted on OTC medicines from consumer behavior perspectives,
especially, purchase decision in Ethiopia.

Introduction
The use of non-prescription medicines is the most prevalent form of medical care in the world (Covington, 2002),
and it have seen greater sales growth than that of prescription medicines since 2008 (Tisman, 2015).
OTC medicine market is expected to continue expanding in the near future for several reasons. Firstly, self-
medication is growing and OTC medicines provide a convenient and inexpensive way to treat minor and
ordinary health problems. Secondly, prescription only-to-OTC switching is not likely to abate, making more
medications available without a prescription. Thirdly, health literacy is likely to increase, especially as use of the
internet as a source of self-medication information expands (Denise, et al., 2010).
In addition, Battistoni et al., (2014) suggested that OTC medicine market has two very peculiar
characteristics; which are, very importantly, consumers buy products in response to their specific health needs;
nonetheless, the market is not strictly regulated in the same way that the prescription market, which allows firms
to choose their pricing and communication strategies. On the other hand, consumers are not forced by physicians
to buy one specific drug, so they can choose the one they prefer by themselves.
Recently, the practice of OTC medicine consumption is widely accepted and successfully integrated into
many health care systems throughout the world (WHO, 2000). In most economically deprived countries
including Ethiopia, many drugs are dispensed OTC and majority of health related problems, nearly 60- 80%, are
treated through self-medication as lower cost alternative and if it is used appropriately, use of OTC medicine
could lighten the demand on doctors and make people more health conscious (DACA and MSH/ SPS, 2009).
According to FMoH & WHO (2003), the pharmaceutical industry has always been of interest to marketers
as a large and internationally competitive industry. Therefore, understanding consumers’ behavior before they
made purchase decision will help for product manufacturers and service providers to develop strategies in line
with customers’ actions. Particularly knowing what makes customers to prefer between brands will make the
manufacturer to adapt strategies based on the influential factors (Kotler and Armstrong, 2012).
The private pharmaceutical market is supplied majorly by the products, which are being imported from
different companies from different continents (Andualem, 1995). Though compiled data on most of the
pharmaceutical economics are rare, it can, however, be said that the country doesn’t have a developed
pharmaceutical industry, but only few and small factories which mainly manufacture generic products using a

commissioned master formula developed elsewhere. These factories produce some 25-30% of the essential drugs
that the health sector of the country needs. The remaining 70-75% of the country’s medicines market has been
left vacant for imported products (FMoH & WHO, 2003).
Bond (n.d.) also explained in most of the world, access to and supply of medicines is governed by a
regulatory framework that is based on perceptions of the risks and benefits of the medicine to the population.
Accordingly, there are two broad categories of medicines in Ethiopia: Prescription only medicines (POM);
medicines only available to the public when prescribed by an authorized medical practitioner such as medical
doctors, nurses, health officers, and dental doctors, and Non- prescription or Over- the- counter (OTC) medicines;
medicines that can be sold directly to a consumer without a prescription from pharmacy personnel.
Currently there are more than 24 therapeutic categories of OTC medicines and within these categories; there
are more than 92 types of OTC medicine in national drug list of Ethiopia (FMHACA, 2012).
Research Objectives
The general objective of this study was to investigate factors affecting consumers purchase decision of over-the-
counter (OTC) medicine from community pharmacies in Ethiopia and specific objectives were;
To examine the effect of pharmacist's recommendation on consumer purchase decision of OTC
medicines.
To determine the effect of family's and friends' recommendation on consumer purchase decision of
OTC medicines.
To identify the effect of country of origin on consumer purchase decision of OTC medicines.
To analyze the effect of previous experience on purchase decision of OTC medicines.
To identify the effect of price on purchase decision of OTC medicines.
Literature Review
Several studies have been conducted in different countries of Europe and Asia to examine factors affecting
consumers purchase decision of OTC medicines. As the researchers’ noted, few studies have been conducted on
OTC medicines from pharmacy practice perspective (Girma, et al., 2011), (Abdissa & Anbessa, 2015),
(Mohammed, 2017), and (Tewodros, et al., 2015). However, in the best of authors’ knowledge, no research has
been conducted on OTC medicines from consumer behavior perspectives, especially, purchase decision in
Ethiopia.
Therefore, this study will provide an insight to pharmaceuticals marketers on factors which affect consumer
purchase decision of OTC medicines. In addition, based on the finding, pharmaceutical marketers will design
their marketing strategies, in efficient and effective manner to have sustainable competitive advantages.
Moreover, the result will have paramount importance for being as a baseline for further study.

communication about products or services, and it plays a key role in influencing consumer attitudes, tendencies
and behaviors. In addition, they suggested that WOM has major impact on consumer choice and post purchase
perceptions. The information about the brand has been used by the other group members also affect the decision
to skip the existing brand and to move on to the purchase those brand that is using by other group members.
Cîrstea, et al. (2017) also believed that the purchase decision is influenced by two important factors medical or
pharmacist advice and the perceived value of information, which can be from reference groups; primarily people
who have purchased / used that drug, as well as colleagues, friends or family.
iii. Country of Origin
According to Saydan (2013), country-of-origin is one of the most important factors that significantly influence
the purchasing decision of consumers. the country of origin “made in label” has been used as an important
function in meeting with today’s competitive and global environment in order to increase product sales. Laroche
et al., (2005) also revealed that a product’s country of origin influences consumers’ evaluation of it. In addition,
Pappu et al. (2006) in their study suggested that country of origin of a product is an important marketing element
known to influence consumer behavior.
Finally, familiarity with the name or brand has also been reported in pharmacy is an important factor
influencing purchases of OTC medicines. This is because medicine’s country of origin, which was associated
with the manufacturing company’s background, as well as by the manufacturing company have valuated higher
than the product’s advertisement and packaging (Kevrekidis, et al., 2018).
iv. Previous Experience
Because the effect of a drug on health conditions can be learned only through use, prior experience with and
knowledge about the product play significant roles in purchase decisions. Due to the difficulty to obtain such
information about the drug’s quality, patients are quite reluctant to switch once they have found a drug that
works for them (Wieringa, et al., 2015).
Consumers’ purchasing experience involves the internal and external memory which would play an
important role in the purchasing process (Bettman, 1979). Internal memory comes from the actual experience
consumers have with the goods or service while external memory is originated from information related to the
goods or service. The experience of purchasing last longer and will remain in consumers’ mindset. Therefore,
they will immediately start evaluating on the items they purchased and the result of the purchasing experience
toward the items will be kept in their mindset for a very long time (Keller, 2001).
According to Shohel, et al. (2013), direct experience with the product, price range and brand reliance are
important determinants of repetitive purchase behavior on OTC drugs. Dadhich & Dixit (2017) also reflected
that familiarity with the OTC brand is the key factor in determining the repetitive purchase of OTC product.
Lastly, decision-making could originate from consumers’ existing knowledge or experience. The emphasis
on previous experience was supported by the reported tendency of the participants to often pick a specific
product from a certain category of medicines, which implies that they are loyal and long-term user of certain
medicines (Kevrekidis, et al., 2018).
v. Price
Consumers are sensitive to the prices because they want to get maximum benefits of using their money and time.
That means, consumers are very rational to judge what they are getting from buying a product or service in
exchange of their payments for it (Mamun, et al., 2014). Other scholars, Gogoi (2013), and Kevrekidis, et al.
(2018) also described that customers always think that purchase with a low cost, simple packaging and little-
known product is a high risk since the quality of these products is not trustable.
Likewise, Asamoah and Chovancova (2011) suggested that consumers are price takers and accept prices at
face value or as given by the producers. Marketers acknowledge that consumers are vigorously assess price
information, decoding prices in terms of their knowledge from previous purchasing experience, formal
communications (advertising and sales promotions), informal communications (friends, colleagues, or family
members), and point-of-purchase or online resources.
Conceptual Model
Based on the above related literatures and concepts the following conceptual framework was developed.

Research Hypothesis
H1: Pharmacist's recommendation has a positive and significant effect on consumer purchase decision of OTC
medicines.
H2: Family and friends' recommendation have positive and significant effect on consumer purchase decision of
OTC medicines.
H3: Previous experience has positive and significant effect on consumer purchase decision of OTC medicines.
H4: Country of origin has positive and significant effect on consumer purchase decision of OTC medicines.
H5: Price has positive and significant effect on consumer purchase decision of OTC medicines.
Methodology
This study was conducted from March 01, 2018 to April 27, 2018 at Addis Ababa, the capital city of Ethiopia.
Addis Ababa has 10 Sub cities and 116 Woredas and covers an area of 540 square kilometers. Addis Ababa is
the largest city in the country. The total projected population of the city is 3,384,569 with annual growth rate of
3.8%. There are 662,728 households in 628,984 housing units (CSA, 2007). As per the Food, Medicine, health
Care Administration and control Authority (FMHACA) of the city, there are 480 community pharmacies in the
city.
As a capital city, Addis Ababa is the center of the country’s trade activities including the pharmaceutical
market. The main reason why the researcher selected Addis Ababa as study area was that the population comes
from different regions of Ethiopia; they can represent different culture, religion, political, commercial and
economical backgrounds. As a result, the finding of the study can be generalized at country level.
A quantitative research approach was used to test the effect of varies factors on consumer purchase decision
of OTC medicines. To achieve the objective of the study, the researcher used both descriptive and explanatory
research design to investigate those factors affecting consumers purchase decision of OTC medicine, and the
relationship between each independent and dependent variable.
Both primary and secondary data was collected from various sources using data gathering instruments to
make the study complete and achieve its predetermined objectives. All sample respondents are the primary
source of data while available documents such as books, past literature reviews and relevant articles were used as
secondary data.
There are two types of population used in this study. Firstly, this study targeted community pharmacies to
intercept the study participants. It is mainly because, community pharmacists are most accessible to the public,
an opportunity to become more than medication dispensers. They supply medicines in accordance with a
prescription or, when legally permitted, sell them without a prescription. Unlike community pharmacies, the
businesses of hospital pharmacies are depending on prescription only medicines that are from respective hospital
where they are in (Melton and Lai, 2017). According to the data obtained from Addis Ababa Food, Medicine,
and Health Care Administration and Control Authority (AAFMHACA), there are 480 community pharmacies
found in Addis Ababa (Internal document contacted on February 26/2018). Secondly, this study considered all

Ethical Consideration
An official letter from Addis Ababa University School of Commerce department of Marketing Management was
written to community pharmacies to get permission. In addition, the entire study participant was informed about
the purpose of the study and finally their oral consent was obtained before giving the questioner. The
information provided by each respondent has been kept confidential and will only be used for research purpose.
Analysis
Out of 426 questionnaires distributed to targeted respondents, only 409 were complete, valid and appropriate for
analysis, which represent 96 % valid response rate.
Reliabilities of the scales were checked after coding and entry of data into SPSS version 23.0. Cronbach’s
alpha coefficients were computed for each scale to determine the internal consistency reliability of the
instruments used in the study. Cronbach’s alpha value of 0.60 is considered as in the lower limit of acceptability
(Malhotra & Birks, 2007), and the overall alpha value is 0.894 which shows the highly acceptability of the
measurement scales used.

decision). Since, coefficient of the predictor variables were statistically at <5% level of significance, alternative
hypotheses related with pharmacists’ recommendation, price, and country of origin were accepted.
Though, past experience and families’ and friends’ recommendation have positive effect on purchase
decision of over- the- counter medicine, it is not significant (P- value 0.147, and 0.155 respectively). Therefore;
alternative hypotheses related with past experience and families’ and friends’ opinion and recommendation were
rejected.

Discussion
This study was carried out to answer the researchers’ five main questions which were listed in chapter one.
Namely, how does pharmacist's recommendation affect consumers purchase decision of OTC medicines? To
what extent family's and friends' recommendation affect consumers purchase decision of OTC medicines? How
does country of origin affect consumer purchase decision of OTC medicines? How a past experience does affect
consumer purchase decision of OTC medicines? And to what extent does price affect consumer purchase
decision of OTC medicines?
As a result, the study revealed that pharmacist's recommendation has a positive and significant effect on
consumers’ purchase decision of OTC medicines with a mean value of 3.93.
This is supported by the finding of Kevrekidis, et al. (2017), which was conducted in Greece that has a
mean value 4.31. In addition, the finding is supported by Haramiova, et al. (2017), Talabă and Andreia (2010),
Cîrstea, et al. (2017), and Boström (2011). The finding shows that consumers have a deep trust in the knowledge
and competency of the pharmaceutical staff, and that they are easily influenced by them. For this consumer
segment the pharmaceutical staffs are influencers who shape the consumers’ view on different products and
affect their final purchase decision. The pharmaceutical staff can influence the range of products that the
consumer evaluates as an alternative. If we now consider that many consumers take into consideration and also
place their product choice based on the opinion or recommendation from the pharmaceutical staff, the
pharmaceutical staff is likely to have a great influence on consumers’ purchase decision of products
Even though most of the respondents were relatively high paid, they were highly concerned about the price
of OTC medicines. In other words, price also has a positive and significant effect on purchase decision of OTC
medicines of consumers. This implies that OTC medicine consumers usually check the price of OTC medicine
before buying it. The finding is in accordance with the result of Haramiova, et al. (2017), (Villako, et al., 2012),
16

Major and Vincze (2010), Shohel, et al. (2013), and Dadhich & Dixit (2017) which were conducted in different
developed countries especially in Europe and Asia.
Country of origin has a positive and significant effect on consumers’ purchase decision of OTC medicines
with mean value of 3.15. This result is in line with Kevrekidis, et al. (2017), which was conducted in Greece,
which has a mean value 3.63. Shohel, et al. (2013), Dadhich & Dixit (2017), and Boström (2011) have similar
results that explain the positive and significant effect country of origin on consumers’ purchase decision of OTC
medicines. Furthermore, consumers consider country of origin to be important for choosing OTC medicines. It
can be considered that country of origin does guide the decision making process of consumers, after they have
taken into consideration other people’s input. As it is explained in the above, country of origin received an
average of 3.15 which indicates its importance. Based on the finding, the researcher can conclude that there is a
segment whose product choice is influenced by the pharmaceutical company’s country of origin and not only by
product features or others people’s opinions.
Several studies; Shohel, et al. (2013), Haramiova, et al. (2017), Yousif (2016), Boström (2011), (Cîrstea, et
al., 2017), and Talabă and Andreia (2010) explain that recommendation of family and friends is considered as
one of the more important factors that help the consumer choose an OTC medicine. However, this study shows
there is a positive relationship between families’ and friends’ recommendation and purchase decision of OTC
medicines even if the relationship is statistically insignificant. This is in contrary to the previously studied related
literatures.
It is important for pharmaceutical companies that their product is the first product choice which the
consumer makes in that specific product category which is explained by; Shohel, et al. (2013), Haramiova, et al.
(2017), Yousif (2016), Boström (2011), (Cîrstea, et al., 2017), and Talabă and Andreia (2010) as nearly all
consumers say that they usually buy the same OTC medicine again and again. The most common reason for this
purchasing pattern is that they know the product does work and through previous experience they have learnt
about the product and that it is a solution to their problem or need. Some customers do not have the time or
energy to explore other options and buy the same product again. Unlike to these literatures, previous experience
has a positive but insignificant effect on consumers’ purchase decision of OTC medicines.

Conclusion
As per the finding, pharmacist’s recommendation, price, and country of origin of OTC medicines have positive
and significant effect on consumers’ purchase decision. Thus, consumers’ purchase decisions of OTC medicines
were mainly determined by the pharmacist’s recommendation, price, and country of origin of OTC medicines.
Though, past experience and family's and friends' recommendation have positive effect on consumers’ purchase
decision, it is not statistically significant.
Recommendations
Depending on the findings and conclusions made, the researcher forwards four main recommendations. These
are;
1. Marketers of OTC medicines especially, wholesalers and importers could benefit from considering
community pharmacists as main targets for their promotional activities such as, new OTC medicine
launch, continuous medical education (CME) as well as detailing (personal selling).
2. OTC medicines wholesalers and importers could also benefit from focusing on their pricing strategies
so as to have competitive advantages and manage needs of their consumers.
3. OTC medicine marketers could also capitalize on the country of origin for their products in their
strategies through different promotional activities which targets professionals who have direct contact
with consumers. This is because commercial advertising of pharmaceutical products is not yet practical
in Ethiopia.

4. Lastly, the researcher recommends further research on previous experience and families’ & friends’
recommendation to examine their effect on purchase decision of OTC medicine.
