Aim: To examine the range of services pharmacists provide and their impact on patient outcomes, harm reduction, and appropriate opioid use.Methods: Six databases were searched (MEDLINE, EMBASE, Scopus, PsycINFO, CENTRAL and Cochrane Methodology Register) from inception to March 2023. The protocol was registered in PROSPERO (CRD42023401895).Results: Twenty-nine studies identified five key areas of pharmacist interventions in opioid management-naloxone programs and opioid de-escalation, patient and primary healthcare providers' education and motivational interview, prescription monitoring and opioid risk screening, clinical pharmacy interventions (pharmacotherapy, medication review, prescribing, adherence monitoring), and collaborative healthcare approaches to promote optimal opioid use. Outcomes assessment indicated harm reduction, improved safety, increased non-opioid analgesic use, decreased opioid consumption, and enhanced pain management.Conclusion: This review underscores pharmacists' vital role in tackling opioid misuse, overuse and abuse, providing a foundation for evidence-based policies to minimize harm and promote optimal opioid use.
