Antimicrobial use in a country with insufficient enforcement of pharmaceutical regulations: a survey of consumption and retail sales in Ulaanbaatar, Mongolia. Southern Med Review (2010) 3; 1:19-23
Abstract Objective: To examine the inappropriate use of antimicrobials by investigating (1) actual utilization pattern and retail sales and (2) antimicrobial resistant information provided by health professionals in Ulaanbaatar, Mongolia. Methods: We investigated antimicrobial use in Ulaanbaatar, Mongolia by surveying 619 consenting customers who attended 250 randomly chosen pharmacies in December 2006. Pharmacy staff were also interviewed about antimicrobials purchased. In January 2007, we surveyed 117 consenting Ulaanbaatar medical doctors from seven local hospitals about their perceptions of treatment failure due to antimicrobial resistance. Results: Among 619 pharmacy customers, 48% of them had bought at least one type of antimicrobial medicine and, of these, 42% had a prescription to purchase antimicrobials. On average, 67% of the customers reported that a pharmacy worker had given them information regarding the dose and timing at which the medicine should be used but only 9% reported that they had been given information regarding possible adverse effects. The survey of medical doctors suggested that some antibiotics had become less effective clinically between 2001 and 2006. Conclusion: The study shows that less than half of all customers who purchased an antibiotic at a pharmacy had a prescription. This shows that antimicrobials can be readily purchased without a prescription despite the existence of laws making such practices illegal. There is a need to establish a vigilant drug regulatory authority to promote enforcement and regulation of medicines in Mongolia. To create awareness regarding the dangers of antimicrobial resistance, educational campaigns for consumers are also necessary.

Table 2 shows the number of customers who bought each
type of antimicrobial medicine per 50 customers who visited pharmacies to buy medicine.
Among the 619 pharmacy customers who agreed to participate in this study, 48.0% of them (297 customers) had bought at
least one type of antimicrobial medicine. Among those who
bought antimicrobials, 42.1% of them (125 customers) had a
prescription for the antimicrobial medicine that was purchased.
Antimicrobials commonly used by injection were benzylpenicillin
(used by 90% of customers who bought antimicrobials), cefazolin (80%) and gentamicin (90%).
The most common reasons for purchasing antimicrobials
were acute respiratory disease (54.8%), genitourinary disease (15.5%), and gastrointestinal disease (10.7%). Among the
pharmacy customers who suffered from acute respiratory disease, 45.1% of them bought oral penicillin, either amoxicillin
(24.6%) or ampicillin (20.5%). The most common strength of these two antimicrobials was 500 mg (selected by 70% of

The pharmacy worker survey indicated that, amoxicillin and
ampicillin, sulfamethoxazole-trimethoprim, and metronidazole were the most frequently sold antimicrobials in Ulaanbaatar
pharmacies. The frequent sale of amoxicillin and ampicillin, both of which are oral penicillins, as over-the-counter drugs has also
been reported in Vietnam and Mexico16, 17. The frequent use
of these medications is most likely explained by their cost and availability: amoxicillin and ampicillin are generally less expensive
than other antimicrobials, and over 70% of all pharmacies
throughout the world sell amoxicillin18. All pharmacies in the
present study sold both amoxicillin and ampicillin. Generally, variations in the types, frequency, and methods in which
antimicrobials are used by the general public vary in countries according to disease patterns, patient characteristics, and
the quantity and quality of care services at health facilities19.
Variations in the general characteristics of antimicrobial use in developing counties also arise from the ability to purchase
antimicrobials inexpensively and without a prescription.
Among the pharmacy customers who bought over-the-counter medicines, more than half of the customers were
seeking treatment for acute respiratory diseases; amoxicillin and ampicillin were sold to more than half of these customers.
Antimicrobials were also frequently sold to patients suffering
from genitourinary or gastrointestinal diseases.
