Objective This study was conducted to assess current situation of medicines shortages in Pakistan and to identify its impact, reasons and possible solutions to overcome the barriers.
Design A qualitative study.
Setting The study was conducted between May 2018 and July 2018 in three cities of Pakistan including Islamabad, Karachi and Bahawalpur, depending on the availability of most relevant key informants.
Participants Health regulators, pharmaceutical manufacturers, pharmaceutical distributors and pharmacists.
Primary and secondary outcome measure Study primarily explored current situation, reasons and potential solutions of medicines shortages in Pakistan. Secondary outcome was the issue of particular brand shortage.
Method Semistructured interviews were conducted. Sample size was determined by using saturation point criteria. Convenient sampling techniques were used to recruit the participants. The interviews were audiorecorded and transcribed verbatim. Data were analysed using inductive thematic analysis.
Results A total of 41 stakeholders including 12 health regulators, 6 pharmaceutical manufacturers, 8 pharmaceutical distributors and 15 pharmacists participated in this study. Data analysis yielded 4 themes, 16 subthemes, 51 categories. Essential and life-saving medicines were in short supply. The major reasons of short supply of medicines were active pharmaceutical ingredient and raw material availability issues, lack of traditional distribution system and sudden demand fluctuation. Among proposed solutions, three most common were the facilitation and regulation of manufacturers, reasonable price fixation and improvements in the inventory control system.
Conclusion Medicines were short in supply, and this may have clinical and financial impact on the patients in Pakistan. There were multiple and complex reasons of medicines shortages. Mandatory government leadership is required to resolve the issue on priority basis for improving the access of medicines to the patients.

Strengths and limitations of this study
This was more likely the first qualitative study undertaken to explore the evidence-based reality of the medicines shortages crisis in Pakistan. This will aid policymakers in the development and pursuance of standard protocols to overcome medicines shortages.
The study population was chosen to give a thorough representation of stakeholders involved in the Pakistani pharmaceutical supply chain.
This study provided a strong base for the future researchers to better quantify and understand the factors responsible for triggering medicines shortages.
Some important stakeholders such as patients and physicians were not included because the study was focused towards the supply side of medicines only.
According to the WHO, the availability of safe, effective and quality essential medicines is fundamental to achieve highest standard of human health.1 However, frequent medicines shortages have been documented from high-income, middle-income and low-income countries.2 In 2017, the WHO stated that almost 2 billion people have no access to basic medicines3 causing inferior patient care and costly financial implication. The WHO described medicine shortage as ‘the supply of medicines, health products and vaccines identified as essential by the health system is considered to be insufficient to meet public health and patient needs’.4 While according to the US Food and Drug Administration (FDA), medicine shortage means a timeframe when the demand or estimated demand for the medicine excels the supply of the medicine.5 Medicines shortages is not a newfangled issue, but the scope and extent has aggravated over recent years.6 The American Society of Health-System Pharmacists (ASHP) reported that by the end of 2017, 146 medicines (that has been increased to 224 medicines by the end of June 2018) were in short supply.7 In 2018, a Canadian report revealed that there were shortages of approximately 1000 medicinal products annually.8 The reports from Europe, Australia, Africa, China, Brazil, Fiji and Israel also indicated that medicines shortages were experienced on a regular basis and the trend has been growing rapidly.9–15
Medicines shortages represent a notable public health hazard, affecting any category of medicine (generic, paediatric, orphan, biologic, radiopharmaceuticals and so on).16 Medicines shortages have generated significant healthcare barriers and its consequences involve therapeutic differences, safety issues (compromised outcomes, medication errors, death and so on) and financial ramifications (higher hospital expenses, increased labour costs, increased cost for patients and so on).17–20 Beside this, wholesalers, distributors and producers may experience reduced profit, bad reputation and unhealthy relationship with the clients and authorities.21 22 There are multifarious and diverse causes of the medicines shortages which differ from region to region. The elements contributing to an interruption in the availability of medicines summarised in WHO and ASHP reports include: (1) manufacturing problems and regulatory issues; (2) voluntary recalls; (3) raw or bulk materials supply issue; (4) alternation in product formulation or manufacturer; (5) limited drug production, supply and allocation; (6) industry consolidations; (7) manufacturers decisions and economics; (8) natural disasters; (9) fragmented demand and shifts in clinical practice; (10) grey market; (11) poor inventory control; (12) non-traditional distributors and (13) restricted drug product distribution and allocation.2 17 23
Pakistan, a low middle-income country, is very likely to experience medicines shortages, where lesser proportion of the total healthcare budget is allocated for medicinal products and medical appliances.24 Pakistan has a typical pharmaceutical supply system. Medicines manufactured in pharmaceutical industries are relocated to distributors and wholesalers, stocked at retail setups or healthcare institutes, prescribed by medical doctors, dispensed at pharmacies or medical stores and eventually provided to and taken by the consumers.25 The import of raw material, manufacture, storage, distribution and sale of medicines in the country are controlled under the Drugs Act, 1976 (XXXI of 1976). The implementation of the Drugs Act, 1976 is ensured by the Drug Regulatory Authority of Pakistan (DRAP) (established under the DRAP Act, 2012).25 26 DRAP has a committee on availability of life-saving drugs that specifically deals medicines shortages. Despite the presence of a regulatory authority in Pakistan, medicines shortages are triggered by persistent policy gap between the health sector and the pharmaceutical industry, lack of implementation of existing policies, hasty process of registration, failure to regulate price, lack of online notification system and inadequate sentencing practices for non-compliant stakeholders.27–29 Different reports from Pakistan revealed that there were severe shortages of antituberculosis medicines, cough and cold medicines, thyroid regulating medicines, neurological disorders medicines, hepatitis medicines and orphan medicines due to regulatory and supply side hurdles.30–33 In a Pakistani study, 55% physicians and pharmacist working in the tertiary care hospitals of Karachi responded that they have faced shortages of various brands of medicines. According to the study, 89% physicians and 93.2% pharmacists reported that medicines shortages led to adverse effect on treatment including treatment delay, complications of treatment, substandard treatment, prolonged hospital stay, increase treatment cost and even death of the patient.34
The International Pharmaceutical Federation recommended country-specific investigations to explore the contributing factors and possible solutions to prevent medicines shortages.35 To date, evidence-based research data on medicines shortages is lacking and very limited studies are conducted in Pakistan. Even though, in 2017, Fatima and Khaliq quantitatively investigated this issue and explored the views of physicians and pharmacists.34 But according to the grey literature, medicines shortages in Pakistan were mainly linked to regulatory and supply side issues, and major stakeholders involved were healthcare regulators and pharmaceutical manufacturers.30 31 33 36 37 However, as of this date, none of the study from Pakistan appeared to gain the perspective of these important stakeholders. Moreover, despite the higher prevalence of particular brand shortage as compared with generics,34 there was dearth of data regarding the issue of particular brand shortage and its associated factors. Therefore, this study was conducted to fill the research gap and provide detailed multiperspective understanding of medicines shortages at different levels in the supply chain. We emphasised on exploring the intricacies of the medicines shortages crisis through a qualitative lens for the very first time in Pakistan to identify the underlying reasons and potential solutions to overcome the barriers. Beside this, phenomena of particular brand shortage were also taken into account as a secondary objective.
Pakistan is a South Asian country. This study was conducted in three cities of Pakistan including Islamabad, Karachi and Bahawalpur, depending on the availability of most relevant key informants. Islamabad is the capital territory of Pakistan while Karachi is the most populous and largest city of the country. Bahawalpur is the main city of the southern Punjab, Pakistan. In Pakistan, the Ministry of National Health Services, Regulations and Coordination regulate health services including supply of medicines. Medicines shortages are dealt (by subdepartments) on a national level by the DRAP (Islamabad) and on district levels by the health department located in each district (figure 1). In this study, health regulators were recruited from the DRAP and the health department (Bahawalpur). Most of the multinational pharmaceutical companies have their head offices in Karachi. Consequently, representatives of pharmaceutical companies were recruited from Karachi. Almost all of the pharmaceutical companies have their distribution setup in Bahawalpur. Therefore, head of distribution setups were recruited from Bahawalpur. Pharmacists working in the Civil Hospital, the Bahawal Victoria Hospital and community pharmacies (drug stores) were recruited from Bahawalpur (figure 1).
The primary objective of this study was to explore the current situation and reasons of medicines shortages along with the possible solutions to overcome the barriers. Moreover, part of this study was focused to explore the issue of particular brand shortage.
Study design and stakeholders selection
A qualitative study design was adopted. This methodology was selected based on the nature of the topic because this issue needed to be explored deeply in Pakistan rather than merely the quantification of medicines shortages. To achieve the study objectives, semistructured interviews were conducted using a pilot-tested interview schema. Most relevant key informants were decided based on existing literature,10 38 39 and then interviewees were selected conveniently (figure 1). All stakeholders were invited to participate in the study through telephone call, and further information regarding the study was provided to them via email on demand. Those who consented to participate in the study were face to face interviewed except the representatives of pharmaceutical manufacturers who were interviewed via telephone call. The participants were interviewed at a place convenient to them. The sample size was determined by using the saturation point criteria.40
Data collection and interview schema
Data were collected in stages from May to July 2018. Health regulators from the DRAP and the representative of pharmaceutical manufacturers were interviewed in May 2018. In June 2018, regulators from the health department of Bahawalpur and the head of pharmaceutical distributors participated in the study. Hospital and community pharmacists were interviewed in July 2018. Interview schema was constructed for each stakeholder after reviewing literature and authors’ experiences (see online supplementary files 1−4).10 38 39 The interview schemas were modified by preinterviews with one representative each from the four groups. Final interview schemas included questions regarding basic information about the interviewees and their organisation, overall scenario of medicines shortages, underlying reasons and potential solutions and factors contributing to the shortage of particular brand of medicines.
Audiorecorded interviews were analysed using inductive thematic analysis. All the interviews were conducted in Urdu; the national language of Pakistan and then audiorecords were listened several times and transcribed verbatim by IM. Transcripts were carefully translated in English by IM, and forward–backward translation method was applied on some of the transcripts (20%) to check the accuracy of data.41 Translations were studied again and again to get familiarise with the data. Coding was done manually by all authors. Relevant words, phrases and sentences indicating the study objectives were labelled, and initial inductive codes were generated to split the data into individually coded segments. Codes emerging from early interviews shaped a coding taxonomy that was used to evaluate subsequent interviews. Initial coding was followed by focused coding. In focused coding, the relationship between different initial codes was explored on the basis of similarity, difference, frequency, sequence, correspondence and causation. Final inductive codes were grouped into meaningful categories by IM, IMU and MA. Themes and subthemes were created by bringing several categories together to conceptualise the data. Transcripts, codes and categories were reviewed recursively before producing final themes. Quantification (counting the frequency of each code) and tabulation were also used to improve the reliability of the findings.38 42 Each answer was quantified once per respondent, and the finding indicated by the majority of the respondents was considered as an important finding. Research team had regular meetings and discussions to cross-check that they had a common perspective and understanding of the generated categories. In case of any conflict or disagreement, final verdict was given by MA (senior author). Hierarchy of the findings was decided on the basis of the calculated frequency in descending order, and then results were written to produce final report.
Verbal consent to participante in the study was taken from all the stakeholders. Participants were encouraged to read the purpose of the study and the confidentiality statement before starting the interview. The names of the respondents were not disclosed in the study and the audio recordings were saved in the password protected computer. Respondents were also given the freedom to skip any question or quit the interview at any time.
Patient and public involvement
Patients and public were not involved in planning or conducting this study.
Among all the interviewees invited to participate in the study, five refused (11% refusal rate) to participate because of their busy work schedule and lack of interest in the study. A total of 41 stakeholders were interviewed including 12 health regulators, 6 manufacturers, 8 distributors and 15 pharmacists. Interview duration ranged from 24 to 65 min with an average duration of 35 min. Among the interviewees, 27 were male and 14 were female. The age of the participants ranged from 26 to 62 years. The respondents’ characteristics are given in table 1.
From a saturated pool of information, four key themes were extracted that is, current situation of medicines shortages in Pakistan, its reasons, possible solutions and the particular brand shortage issue.
Theme 1: current situation of medicines shortages in Pakistan
Multiple phrases were used by the stakeholders to describe medicines shortages, including inadequate supply of medicines, an imbalance between the demand and supply or production and unavailability of medicines for particular time period. Almost all the participants said that during the past 12 months, they had seen the situation when medicines were short in the market or in an institute, and according to them, essential, life-saving, controlled and orphan medicines were short. All the regulators and few manufacturers stated that they had taken measures to prevent medicines shortages issue while distributors declared themselves handicap in doing so. On asking about the notification system, the majority of the regulators informed that they had received or sent notification regarding medicines shortages while none of the manufacturer and distributor reported a proper notification system. Subthemes, categories and exemplar quotations related to theme 1 are given in table 2.
A list of short medicines reported by the stakeholders during last 12 months is given in table 3.
Theme 2: reasons of medicine shortages
Multiple and complex reasons of medicine shortages were indicated by the stakeholders on different levels. On manufacturer level, the majority of the participants indicated that the main reason of medicine shortages were the raw material related issues, including import issues, availability issues, pricing and quota allocation for controlled raw material (37 out of 41respondents) and planning and forecasting gap. On distribution level, the main reason reported by the study participants was the intermittent or inadequate supply of product from the manufacturer’s side and the other reason indicated was the biassed distribution of short products. In hospital setting, the majority of the participants described that there was poor inventory management and procurement procedure (27 out of 41 respondents). According to them, the contributing factors in the poor inventory management were a poor demand prediction, poor procurement procedure, pilferage of the medicines and the poor storage conditions. Other issues highlighted by many participants were budget constraints and delayed quality control testing. Based on the market attributes of the product, the low price and low demand were the major reasons of shortage of medicines (26 out of 41 respondents). Subthemes, categories and exemplar quotations related to theme 2 are given in table 4.
Table 5 shows most common reasons associated with medicines shortages. The most common reason was raw material-related issues and least common was production hurdles.
Theme 3: possible solutions of the medicines shortages
All the stakeholders provided practical suggestions to alleviate medicines shortages. They recognised the government as having the authority of resolving this issue. The majority of the respondents recommended that the manufacturers should be facilitated, motivated and regulated by the government for the continuous production and supply of medicine (28 out of 41 respondents). Other important solutions proposed by most of the participants were the reasonable price fixation (25 out of 41 respondents) and the establishment of reserve system of medicines by the government. On manufacturer level, the availability of backup raw material was the common solution suggested by most of the respondents. Many informants also suggested that manufacturers must ensure the availability of commercially and financially non-viable product on ethical grounds. According to the majority of the participants, the most frequently proposed solutions on the distribution level were the development of unbiassed distribution system, strong and healthy interaction of distributers with manufactures, supply chain management, good storage practices and increased human and monetary resources. In healthcare institutes, improvement in the inventory control system (19 out of 41 respondents), extra budget allocation and strengthening of the pharmacist role were some of the possible solutions to prevent the medicines shortages issue. Subthemes, categories and exemplar quotations related to theme 3 are given in table 6.
Table 7 shows most common solutions to overcome medicines shortages. Among the most common solutions, 28 participants stated that manufacturers should be facilitated, motivated and regulated to resolve the issue, while 15 participants stated that there should be generic prescribing and improvement in the distribution system to overcome the medicines shortages issue.
Theme 4: particular brand shortage issue
Multiple reasons of particular brand shortage were reported by the stakeholders. Among these, lack of traditional distribution system (32 out of 41 respondents), accidental and seasonal demand increase (30 of the 41 respondents), production hurdles (17 out of 41 respondents), irrational prescribing (22 out of 41 respondents), limited number of registered companies for a particular active pharmaceutical ingredient and batch recall due to quality and stability issues were the major reasons reported by the study participants. The suggestion for preventing particular brand shortages included; promotion of traditional distribution system, promotion of generic prescription (15 out of 41 respondents) and issuance of registration of multiple brands of same active pharmaceutical ingredient to other manufacturers. The patient-related factors influencing the demand of a particular brand were their preference to doctor prescription, lack of knowledge and awareness and trust on specific brand and psychological acceptance. The reasons of prescribing a particular short brand by the doctors included; influence of the promotional marketing strategies by the pharmaceutical companies (34 out of 41 respondents), reliability and confidence of doctors on particular brand (23 out of 41 respondents) and lack of information about the shortage. Subthemes, categories and exemplar quotations related to theme 4 are given in table 8.
Based on study findings, figure 2 summarises reasons and overall solutions of medicines shortages in Pakistan.
Medicines shortages is a frequently rising global phenomena posing a significant health risk to the patients and burdening the healthcare system.15 39 43 The WHO stated medicines shortages as a very less-investigated issue in low-income and middle-income countries,2 and this is the first qualitative study to gain in-depth understanding of complex and multifaceted medicines shortages issue in Pakistan. In this study, 4 themes, 16 subthemes and 51 categories emerged. The themes highlighted the current scenario of medicines shortages in Pakistan, its reasons and possible solutions and particular brand shortage issue.
In this study, different types of terminologies were used by the participants to describe the medicines shortages, and all terminologies were comparable with the definitions of medicines shortages given by the WHO and FDA.4 5 For example, our respondents stated that medicine shortage is the gap between the demand and supply or production, unavailability of product at any given time and unavailability of medicines for all age groups and entire dosage regimen. Likewise, a European study stated that medicines shortages could be expressed as demand and supply imbalance or interrupted supply or the unavailability of medicines to satisfy the patient needs.44 According to the results of our study, shortages of essential medicines, life-saving medicines and orphan medicines were frequent during the last 1 year in Pakistan. Few previous grey literature reports also indicated shortage of orphan and essential medicines in the country.30–32 The gap in the essential medicine access is driven by inefficient Pakistani healthcare system and pharmaceutical regulations, which necessitates multidimensional integrated approaches to ensure the availability of medicines.45 These findings were concurrent with the typology of medicines shortages presented by the Chinese and European studies.10 43
Our respondents elaborated that no single aspect can be considered as a reason of medicines shortages. Among multiple reported reasons, the major reason was raw material-related issues including its import hurdles, unavailability, high cost and restricted quota allocation. According to a report, medicines shortages occurred in the USA due to interruption in the raw material supply because 80% of it was imported from abroad.17 The reasons of unavailability of raw material could be limited suppliers or manufacturers of raw material, political conflicts leading to import hurdles, regulatory restrictions on the import and allocation of controlled substances, long delivery time, issues in the extraction of raw material due to the environmental changes, complex production chain, quality issues and issues in the transport and storage.17 21 38 In Pakistan, most of the raw materials and active pharmaceutical ingredient are imported from India, China, Europe, North America and other countries.25 According to news reports, increase in the value of the US dollar as compared with Pakistani rupee resulted in increased cost of raw material and subsequent shortages of life-saving medicines.31 46 Beside this, quota of controlled substances in Pakistan is allocated by the Narcotics Control Board in consultation with DRAP.36 47 The stringent control on controlled substances for example, ephedrine, pseudoephedrine and delay in the quota announcement had created the medicines shortages in the country.36 37
Poor inventory management and procurement procedure was another reason of medicines shortage in Pakistani hospitals. Many previous studies including a Pakistani study highlighted that inventory mismanagement was one of the major factors undermining the medicines access in hospitals.10 48 According to the reports, contributing factors in the poor inventory management could be inadequate budget, physicians preferences, limited information sharing and lack of active role of pharmacist,49 50 while poor procurement could be due to delays in tendering, absence of contractors and incapability of the suppliers to fulfil demand.2 In view of our study participants, the second major reason of medicines shortages in the hospital context was budget constraints. Likewise, a previous study revealed that inadequate funding or poor budget management was a reason of poor availability of medicines in Pakistani hospitals.45 In Pakistan, the amount allocated for medicines in the public healthcare centres is below the critical threshold of $2 per capita per year suggested by the WHO to prevent medicines shortages.51 Beside this, inefficient budget management further exacerbates this issue in the country.45 Multiple factors contribute to inefficient budget management, including inadequate demand prediction, poor procurement, medicine pilferage and unavailability or lack of active participation of pharmacists.45
Product’s financial non-viability or low price was also considered as major reason of medicines shortages by our respondents, and this finding is in accordance with the findings of studies from Belgium, France and China.10 39 Low price issue may further leads to parallel distribution, grey market, permanent discontinuation of product due to lack of market attractiveness and thus complicating the medicines shortage issue.38 39 In Greece, 203 products were withdrawn from the market due to low market price.52
The study participants viewed the government as having the authority to resolve the medicines shortages issue. Among the proposed solutions, the most important were the facilitation and regulation of manufacturer, reasonable price fixation and improved inventory control system in hospitals. The government should immediately regulate and bind the manufacturers to ensure the availability of medicines and should resolve their issues. The FDA has also considered the regulation and facilitation of manufacturers as one of the short-term strategic plan for preventing and mitigating medicines shortages.53 Besides regulation and facilitation of the manufacturers, reasonable price fixation was proposed as another short-term solution of medicines shortages in Pakistan. The WHO has also emphasised fair pricing for both the supplier and consumer to prevent medicines unavailability.2 Matching suggestion was also proposed by the participants of a Chinese study, in which they quoted a notion that ‘a higher price but available in the market’ is better than ‘a lower price but no access’.10 Reasonable pricing may well persuade pharmaceutical manufacturers to increase their production and supply. The governments should negotiate with the patent holders on priority basis to reach a mutually acceptable price agreement2 after carefully considering different price components, including registration, postapproval activities, importation cost of raw and packaging materials, transportation charges, direct and indirect manufacturing costs and maintenance costs,39 54 especially in Pakistan, where medicines shortages were the consequences of years of deadlock between DRAP and the pharmaceutical manufacturers over the pricing of medicines.31–33 However, recently in January 2019, taken into account the current situation of medicines shortages in the country and its associated complex reasons such as the 30% devaluation of Pak Rupee against the US dollar and subsequent increased pricing of raw and packaging materials, DRAP has notified 9%–15% increase in the prices of life-saving and other medicines, respectively.46 This corrective measure is expected to immediately address medicines shortages conundrum within the country.
To prevent medicines shortages in hospitals, participants of this study suggested the improvement in the inventory management as a solution through active participation of pharmacists in forecasting, procurement and product selection. Unfortunately, there is limited scope of pharmacy practice and lack of pharmacist acceptance in the Pakistani healthcare settings.55 In this regard, Canadian Pharmacists Association suggested that the government should broaden the scope of practice for pharmacists with the provision of authority to execute the alternative plan autonomously and in collaboration with prescribers. Moreover, pharmacists must equip themselves with additional skills and expertise needed to cope with medicines shortages.56
A Pakistani study reported that shortage of particular brand of medicine was relatively high as compared with generics.34 We explored this issue and found some specific reasons and possible solutions of particular brand shortage. On questioning the respondents, they indicated that lack of traditional distribution system and consequent unlawful practices, including parallel trade, artificial shortage, grey market and selective distribution were the leading and hotly argued reasons of medicines shortages. The only reason behind this unethical practice is to earn high financial benefits at the cost of significant threat to health of patients.17 21 57 Similar causes of medicines shortages were reported in European studies.39 43 Sudden increase in the demand was also indicated as one of the reasons of particular brand shortage by our study participants. A study appraising the medicines shortages in the UK and European countries also revealed that medicines shortages were triggered by unexpected fluctuation in demand.52 This sudden increase might be due to disease outbreak, promotional campaigns, catastrophic events, introduction of new product or therapeutic guidelines and artificial shortage.23 38 58 According to this study, shortage of a particular brand was also highly influenced by the prescribing pattern. The stakeholders further exposed unethical promotional marketing strategies and incentives to be the reason of professional dishonesty. In Pakistani context, the pharmaceutical industries spend a lot of money on promotional strategies and the doctors are highly influenced by the incentives offered to them for prescribing a particular brand.59 A previous Pakistani study has also considered promotional influenced prescribing of particular medicine brand as one of the major barriers in the access to medicines.45 Production hurdles, including limited production capacity, production breakdown and fault in the manufacturing chain were also frequently mentioned reasons of particular brand shortages in this study. In the USA, 168 products were listed short due to manufacturing issues.60 Multiple previous studies have reported manufacturing hurdles as one of the reasons of unavailability of medicine in the market.34 38 39 61
Stakeholders thought promotion of traditional distribution as a mandatory measure to prevent shortage of particular brand of medicine. The ASHP not only highlighted but emphasised the promotion of traditional distribution system through the establishment and implementation of guidelines and strict policies.23 Promotion and implementation of generic prescribing was also considered as one of the important solutions of particular brand shortages in Pakistan. However, implementation of generic prescribing and traditional distribution system could probably be the long-term solutions. The WHO suggested 100% generic prescribing to ensure access to medicines but recent Pakistani studies exposed that minimal drugs were prescribed by generic names.62 63 Although, in 1972, the Generic Drug Act was introduced in Pakistan to forbade the use of brand names and promote the use of generic names in prescriptions but the scheme operated until 1975, and generic marketing and prescribing was revoked by the government due to accelerated promotional activities and failure to bring down medicines prices.64 The government needs to reconsider the implementation of revised generic prescribing policy to prevent the shortage of particular brand of medicine.25 According to our study participants, the major factor influencing patients to demand a particular brand was their preference to doctors’ prescriptions (no substitution allowed). Similarly, with regard to doctors, promotional marketing strategies by the pharmaceutical manufactures, trust on specific brand and lack of doctor’s trust on generics were main barriers to generic prescription that further aggravate possibility and severity of particular brand shortage.25 65–67 A broad literature review and a Poland study have linked increased prescription rate of particular brand with the monetary benefits gained by practitioners from the pharmaceutical companies.65 66 Likewise, previous studies explained that prescribers were more inclined to prescribe a particular brand because they have concerns about the quality and efficacy of generic medicines and believed branded medicines to be superior than the generics.67 68 Sharif et al also exposed that prescribers in Pakistan also favoured brand medicines and considered generics to be of inferior quality.59 To counter such type of misconceptions and ensure quality of generic drugs, the regulators in our study and the FDA recommended comparative biodissolution studies for the generic products in case bioavailability studies are not feasible.69
This study successfully appraised the situation regarding the medicines shortages in Pakistan but still has a few limitations. Although, wide range of stakeholders were involved but some important stakeholders such as patients and physicians were not included in the study. These were excluded because previous grey literature in Pakistan revealed that medicines shortages were mainly associated with regulatory and supply side hurdles and major stakeholders responsible for managing such issues were healthcare regulators and pharmaceutical manufacturers.30–32 Therefore, our focus was more towards exploring the reason and possible solutions of the medicines shortages from supply perspective which can be better addressed at the government and pharmaceutical manufacturing level. Beside this, distributors and pharmacists were included in the study because they were accountable for the medicines supply and management of inventories in both community and hospital settings. It is highly recommended that future research should include patients and physicians to better explore the consequences of medicines shortages and reasons from demand perspective. Other limitation of this study might be the potential bias and findings disparity associated with the employment a mix of phone and face-to-face semistructured interviews because pharmaceutical manufactures only agreed for telephonic interviews due to their strict internal policies. However, to minimise the potential bias and ensure comparable outcomes, a complete respondent information pack (including interview schema) was provided to them before interview. As a result, we found that consented manufacturers were very comfortable and openly provided actual facts when they were assured of their anonymity.
Medicines were short in supply and this may have clinical and financial impact on the patients in Pakistan. Among the complex and multiple reasons of medicines shortages, the major reasons were shortage of API and raw material, non-traditional distribution tactics and sudden demand fluctuation. Among various proposed solutions of medicines shortages, the three most common solutions were to facilitate and regulate manufacturers, reasonable price fixation and improvements in the inventory control system. The main factors associated with shortage of particular brand of medicines were promotional influenced prescribing of a particular brand, doctor’s trust on specific brand and patient preferences.
Impact of findings on policy and practice
The protocols regarding medicines shortages are quite inadequate in Pakistan. The findings of this thorough and objective research will be helpful for the policy makers in the development and pursuance of standard protocols, and short-term and long-term prevention strategies.
Based on findings of this study, medicines shortages could be minimised by adopting short- and long-term strategies. Short-term resolution of medicines shortages could be achieved through facilitation, motivation and regulation of manufacturers, reasonable price fixation, establishment of reserve system of medicines, extra budget allocation by the government and maintenance of raw material inventory by the manufacturers. For long-term curbing of medicines shortages, the government needs to promote traditional distribution system, implement generic prescribing, establish improved inventory control system in hospitals and strengthen the role of pharmacist.
After understanding the complete scenario of medicines shortages in Pakistan, a multifaceted collaborative institutional, societal and patient centred approach is recommended to successfully prevent medicines shortages.
From research point of view, this study provides a strong base for the future multidimensional surveys to better quantify and further access the impact, underlying reasons and potential solutions of medicines shortages to provide continuous feedback to the policy makers.
