Objective: Since coronavirus disease 2019 (COVID-19) became a global pandemic, repurposing known drugs was the quickest way to combat the disease. The initial screening revealed that azithromycin (AZM) might have potential against COVID-19. Although clinical trials did not prove such efficacy, many countries have put AZM within their guidelines for treating COVID-19. Therefore, the present study was designed to assess the misuse of AZM in Jordan during the COVID-19 pandemic.
Methods and Results: A cross-sectional study was conducted among community pharmacies in Jordan from March 27 to May 8, 2021, and 184 pharmacies data were collected from the Google forms. During COVID-19, 42.9% of pharmacies sold more than 20 packs of prescribed AZM per month compared to 46.7% of pharmacies used to sell 0– 5 packs AZM prescriptions per month before the pandemic. During COVID-19, pharmacists significantly dispensed AZM with and without prescriptions 107% and 127%, respectively, more than before the pandemic (p < 0.0001). Overall, pharmacists stocked 121% more AZM packs during COVID-19 than before the pandemic (p < 0.0001). Additionally, most pharmacists (59.7%) believed that AZM could cure COVID-19 patients. However, using multinomial logistic regression analysis, low-experienced pharmacists were unsure if AZM could positively affect COVID-19 patients (p < 0.05, OR = 3.76, 95% CI = 1.23– 11.52). Furthermore, low-experienced pharmacists believed that increased use of AZM for the treatment of viral infections could lead to negative consequences (p < 0.001, OR = 0.161, 95% CI 0.063– 0.414).
Conclusion: This study demonstrated that AZM is misused by physicians, pharmacists, and the public in Jordan. Since AZM efficacy on SARS-CoV-2 is scarce, there is a need for new guidelines by governmental health authorities to implement strict enforcement of AZM dispensing during COVID-19 to avoid negative consequences of bacterial resistance.

Introduction

Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), was first identified as an outbreak of respiratory illness in Wuhan City, China, in 2019.1 Then, in March 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic.2 Since then, SARS-CoV-2 has caused worldwide fear because the infection spread quickly between countries and the clinical course ranged from mild to severe inflammatory disease resulting in multi-organ failure and death.3,4 Due to that, efforts for repurposing known drugs were the quickest way to help combat the disease. After screening FDA-approved chemical library, a group from France demonstrated that Azithromycin (AZM) exhibited the highest in vitro anti-SARS-CoV-2 activity.5

AZM is a second-generation, broad-spectrum, synthetic macrolide antibiotic that inhibits protein synthesis.6 However, it has been shown that AZM has anti-SARS-CoV-2 activities,5,7,8 as well as anti-inflammatory properties, mainly by inhibiting dysregulated production of proinflammatory cytokines.8,9 Furthermore, AZM has been used for treating several previous SARS and Middle East Respiratory syndrome diseases. For example, AZM was associated with improved survival rate and time to discontinue mechanical ventilation in SARS.10,11 Although there was no clinical evidence, AZM was listed in many countries as part of the COVID-19 treatment protocol.12 This led to the public misinformation gained from social media that AZM can cure COVID-19.13

During the second wave of the pandemic (September 2020 and until the study period of this work), Jordan got a very high rate of COVID-19 cases with a daily mortality rate of 2.6/100,000, reaching an overall of ~700,000 positive COVID-19 cases and ~ 10,000 deaths.14 Because of the high rate of COVID-19 cases, public misinformation about AZM and COVID-19, and since buying antibiotics is not strict with prescriptions in Jordan,15,16 many started buying AZM from pharmacies without or with a prescription. Therefore, this study aimed to determine a) if AZM has been misused in Jordan during the COVID-19 pandemic; b) whether pharmacists were dispensing it without a prescription; and c) if physicians were increasingly prescribing it during the pandemic. All in all, the main concern was that AZM resistance would emerge from such misuse.

Materials and Methods

Study Setting and Sample Size Calculation

This cross-sectional study was conducted among community pharmacies in Jordan from March 27 to May 8, 2021. Beforehand, the Institutional Ethics Review Board at the University of Petra approved the study protocol (Q1/11/2021). Then, using a Google Form with written consent for participation in the study, the survey link was distributed to pharmacies on social media. The online message included an anonymous and confidentiality statement; therefore, filling out the questionnaire meant they accepted to enroll in the study.

According to the latest Jordan Pharmacists Association data, there are 2801 pharmacies in Jordan. Therefore, for sufficient statistical analysis, the sample size was calculated to be 184 based on the number of pharmacies, a confidence level of 95%, a margin of error of ±7%, and a 50% response distribution rate.17

Questionnaire and Data Collection

A short questionnaire of 14 questions was designed and distributed online to community pharmacies (Supplementary Material).18 Four questions were related to the person answering the questionnaire, such as age, gender, and if the person was a practicing pharmacist and years of experience in the field. The rest ten questions were on: AZM dispensing with or without prescription; AZM storage by pharmacies in Jordan before and during the COVID-19 pandemic; the pharmacist’s belief that AZM could have a positive effect on COVID-19; and if AZM use for viral infections has negative consequences. Data were collected online via a self-reported questionnaire.

Data Analysis

Data were exported from the Google forms to Microsoft Excel, then transferred to SPSS version 25 for statistical analysis. Data were categorized and recorded in frequencies or values. Chi-square analysis was performed to test for significant association of single variable, whereas multinomial logistic regression was applied to test for independent variables with covariate variable with the calculation of odds ratio (OR) and 95% confidence interval (95%). A 2-sided paired-test was applied when appropriate, and one-way ANOVA was applied when testing for more than two group levels. A p-value of 0.05 was considered significant.

Results

One hundred eighty-four pharmacies responded to the questionnaire. Most of the responders (54.9%) were female pharmacists, between 22–29 years of age (48.4%), and had 0–5 years of experience (48.9%) (Table 1). Besides, 95.7% of the responders were practicing pharmacists. Therefore, the data from the non-practicing pharmacists were excluded for two questions related to AZM treatment for COVID-19 and knowledge of negative consequences.

Table 1 Demography of the Pharmacists and Their Experience

Before COVID-19, 46.7% of pharmacies used to sell 0–5 packs AZM prescriptions per month. During COVID-19, however, 42.9% of pharmacies sold more than 20 packs of prescribed AZM per month (Figure 1A). During COVID-19, pharmacists significantly dispensed AZM with and without prescriptions 107% and 127%, respectively, more than before the pandemic (p<0.0001). However, during the COVID-19 pandemic, AZM dispensing without or with prescription was not significantly different (9.5%, p>0.05) (Figure 1B).

Figure 1 The percentage of pharmacies in Jordan selling AZM per month; (A) with prescription before and during COVID-19, and (B) without or with prescription during COVID-19. During COVID-19, the number of prescribed AZM packs/per month sold was significantly higher than before the pandemic (see the text for more details). However, in (B), the numbers of AZM packs sold during COVID without or with prescription were not significantly different.

In parallel to the above, 54.9% of pharmacies used to stock 5–10 packs of AZM, whereas during the COVID-19 pandemic, 44% of pharmacies began stocking more than 40 packs of AZM (Table 2). Overall, pharmacists stocked AZM 121% higher during COVID-19 than before the pandemic (p<0.0001) (Table 2). Besides, almost all the pharmacists (94.6%) realized increased AZM sales during the pandemic, and 92.9% felt they needed to order more AZM packs.

Table 2 AZM Stocking and Observation of Sales Before and During COVID-19 Pandemic

Pharmacists’ beliefs about the role of AZM in COVID-19 treatment varied based on their experience and age (Table 3). Most pharmacists (59.7%) believed AZM could cure COVID-19 patients. However, the least group who believed in that was the low-experienced pharmacists (47.6%) compared to 84.6% and 65.2% for 6–10 and more than ten years experienced pharmacists, respectively (Table 3). Furthermore, using multinomial logistic regression analysis, low-experienced pharmacists were unsure if AZM could have a positive effect on COVID-19 patients (p<0.05, OR= 3.76, 95% CI = 1.23–11.52) (Table 4). Besides, although more experienced pharmacists (more than ten years) had a trend of stocking more AZM than low experienced pharmacists (0–5 years) before the pandemic (p>0.05), this difference became significant during the COVID-19 pandemic (p<0.001). On the other hand, there was no difference in stocking AZM between highly experienced and middle (6 −10 years) experienced pharmacists before or during the pandemic.

Notably, 52.2% of the pharmacists believed that using AZM to treat viral infections could have negative consequences, and the majority (65.5%) of these were low-experienced pharmacists (Table 5). Furthermore, low-experienced pharmacists’ belief that increased use of AZM for the treatment of viral infections could lead to negative consequences was statistically significant (p<0.001, OR= 0.161, 95% CI 0.063–0.414) (Table 6).

Discussion

Between March to May 2021, Jordan experienced the third wave of COVID-19, and cases were between 2000–9000/day.19 Therefore, the study period should represent a peak of pandemic activity. During this period, the study showed a significant increase in stocking and sales of AZM with or without prescription by 184 community pharmacies in Jordan compared to the pre-COVID-19 period. This increased stocking and sales of AZM was likely due to the initial guidelines, including AZM and its possible effectiveness against SARS-CoV-2 infection and sudden surge of patients seeking Medical- or self-care for confirmed or presumptive COVID-19 condition. Furthermore, several studies, including the WHO, reported increased AZM use.20–23 In addition, some showed increased use of AZM with hydroxychloroquine since some in vitro studies stated that both drugs would show better inhibitory effects on SARS-CoV-2 infection.5,21

A good number of studies reported high use of antibiotics during COVID-19 on hospitalized and non-hospitalized patients.20–25 These uses were partly due to the clinical care guidelines in some countries. However, Goyal et al reported that out of 393 COVID-19 patients in New York, only 5.6% developed bacteremia without receiving antibiotics. Besides, most of the latter frequency occurred in patients on invasive mechanical ventilation.26 Furthermore, in a meta-analysis of bacterial infection in hospitalized patients, only 8% of all patients were found to have coinfections or secondary bacterial infections.27 Since most of these infections were nosocomial infections, the chance of developing secondary bacterial infection for non-hospitalized COVID-19 patients has been considered rare.28 Besides, since the double-blind placebo-controlled studies of AZM with or without hydroxychloroquine for treating COVID-19 did not reveal sufficient efficacy results, there is no scientific evidence for physicians to prescribe AZM for non-hospitalized COVID-19 patients.29,30

In the present study, most pharmacists (59.7%) believed that AZM could treat COVID-19. A recent survey in Jordan showed that most pharmacists (55.8%) get their source of information in response to COVID-19 from social media. In contrast, low percentages get their source of information from either the WHO site (6.0%) or scientific journals (5.2%).31 Since social media containing misinformation or myths increased during the COVID pandemic, general people or professionals started to believe in what they read.15 One of these myths is that “antibiotics are effective in preventing and treating new coronavirus.” Thus, it is not unusual for more than half of pharmacists to believe in that statement.

Furthermore, the present study showed that less experienced pharmacists believed less that AZM could treat COVID-19 disease and believed more of the negative consequences of using AZM in viral infections. Such belief led them to stock less AZM in their Pharmacy during the pandemic. These results may suggest that fresh pharmacy graduates have more assurance that antibiotics should not be used for viral infections unless preventing secondary bacterial infection. On the other hand, the more experienced pharmacist may tend to go with the flow and believe what they read on social media over the scientific knowledge gained during studying their degree.15,31,32 The latter opens the need for continuous education for pharmacists.

Since antibiotic misuse has been high for decades, antibiotic resistance has been of significant concern in developing and developed countries.15,16,32–36 In Jordan, for instance, 73% of Cutibacterium acnes isolated from patients with acne were resistant to erythromycin, 59% to clindamycin, 37% to doxycycline and tetracycline, and 31% to trimethoprim/sulfamethoxazole. Additionally, in a study conducted in 2019 (pre-COVID-19 period) on 504 healthy college students in Jordan, the researchers found that 40.4% of students carried methicillin-resistant Staphylococci isolated from nasal and skin areas.37 These isolates were 46% resistant to cefoxitin, 35% to erythromycin, 13% to ciprofloxacin, 12% to nitrofurantoin, and 10% to gentamicin, but not to hospital-restricted injection-type antibiotics, amikacin (1.5%) and vancomycin (0.5%).37 These results indicate the consequence of the misuse and overuse of antibiotics in Jordan.

The concern for developing more antibiotic-resistance during the COVID-19 pandemic is expected to be significant since the AZM (and other antibiotics) misuse and overuse is two to three folds higher, as presented herein and in other studies.22,27 Therefore, new measures of clinical guidelines on using AZM and other antibiotics for COVID-19 patients in Jordan and other countries are warranted.22,27,36 Furthermore, these new measures should be distributed on social media to overcome and balance the false information that the public and the health practitioners are receiving.

The present study has limitations. Firstly, although the number of required pharmacies was statistically sufficient, the sample size may not represent the whole pharmacies in Jordan. Secondly, other antibiotics could also be highly used during the pandemic in Jordan. Thirdly, the study included a few sociodemographic variables, whereby more variables might clarify the outcome better.

In conclusion, this study demonstrated that AZM is misused by physicians, pharmacists, and the public in Jordan. Since AZM efficacy on SARS-CoV-2 is scarce, there is a need for new guidelines by governmental health authorities to implement strict enforcement of AZM dispensing during COVID-19 to avoid negative consequences of bacterial resistance.
