Essential Medicine
Opioids are essential medicine: WHO Analgesic ladder
1. Acute pain management
2. Chronic pain managementcancer related-cancer related
-HIV palliative care-and non-cancer related: as a final line of treatment
3. Opioid Substitution Treatment

International Treaties
• Unlike other medications opioids are controlled by international treaties:international treaties:
-1961 Single Convention,
‘adequate amount for medical and scientific uses’
-regulated by INCBregulated by INCB

Associated Harms
• Adverse effects compounded when used outside guidelinesguidelines
• Unsupervised use:-Overdose, dependence, medical conditions, sedatives
• Injection: j-HIV & HCV, non-sterile medication. dependence

Case Study: India
• Large scale diversion of pharmaceutical opioids: low potency
• Shift from heroin smoking pharma opioid injectiong p p j
• HIV prevalence IDUs: 10% limited OST & NSP
P ibi f ll t f i i d t i thi i• Prescribing for all types of pain inadequate in this region
• Misuse not been avoided thru limited medical supply

Case Study: United States of America
• 49% of world’s morphine consumption: 4.7% worlds populationpopulation.

Case Study: United States of America
• INCB concern at extent of US problem
• Easily obtained from GPs for diffuse, non-specific pain conditions
• OxyContin aggressively marketed as ‘low dependence’: $600 million criminal charge of ‘misbranding’.
• Diversion: led to increased injection

Summary
• Reduce inequalities
• Reduce diversion
• Reduce harm
