Opioid Use Disorder (OUD) is defined by the persistent use of opioids despite adverse consequences. It is associated with increased mortality and a variety of mental and general medical comorbidities. Risk factors include younger age, male sex, lower educational attainment, lower income, and psychiatric disorders, such as other substance use disorders and mood disorders. Genetics also play a role in susceptibility to opioid use disorders. Long-term self-efficacy in opioid use for non-medical purposes suggests irreversible opioid use disorders.To evaluate the current understanding of opioid use disorders, the limitations in existing treatment approaches were examined, and strategies to improve outcomes through expanded treatment access and personalized care interventions were identified.An analysis was carried out regarding the role of existing pharmacological treatments, barriers within the care cascade, and potential advancements in healthcare delivery and innovation was carried out to address opioid use disorders. A comprehensive review of the literature was conducted by searching electronic databases (e.g., PubMed, Scopus) for articles published over the past 20-25 years. Relevant studies were selected based on predefined inclusion criteria, focusing on OUD risk factors, pharmacological treatments, barriers in the care cascade, and strategies for improving care. The selection process prioritized systematic reviews, clinical trials, and key guidelines.Although medications for opioid use disorders are effective, their impact is hindered by systemic issues at multiple levels of care. Addressing these challenges requires comprehensive efforts, including professional training, innovative treatments, and healthcare reforms to expand access and personalize care.
