Drug repurposing for sustainable antimicrobial use: exploring pharmacists’ awareness, attitudes, facilitators and barriers

This study utilized a validated questionnaire that aimed to assess pharmacists' awareness and attitude towards drug repurposing for antimicrobial use. Despite the reasonable awareness, pharmacists reported unfavourable attitudes. Pharmacists with a B.Pharm. or Pharm.D. degree reported less awareness than pharmacists with a master's or PhD degree. In contrast, pharmacists who dispensed fewer than 10 prescriptions or 10-29 prescriptions had significantly higher awareness than those who dispensed 30 prescriptions daily or more. Pharmacists who had 1-5 years of experience and those who dispensed less than 10 prescriptions daily had significantly lower attitude scores than their counterpats. The most reported facilitator was the reduced risk of antimicrobial resistance, while the most reported barrier was patient safety. Pharmacists' perception of drug repurposing for antimicrobial needs to improve via implementing educational sessions that highlight the impact of drug repurposing on supporting the fight against antimicrobial resistance and promoting a more sustainable and resilient healthcare system.
