Combating Escalating Harms Associated With Pharmaceutical Opioid Use
Funder

Funding Amount
$925,767.00
Summary
Increases in opioid use have been accompanied by increased opioid harms. But there is a lack of population-level evidence about drivers of long-term prescribed opioid use, dependence, overdose and other harms. Using linked data, we will fill these gaps using a cohort of all people in NSW prescribed opioids since 2002, linked to datasets containing information on health, social and health service utilisation, that will permit a comprehensive assessment of the risks of all prescribed opioids.
Novel Prolonged-release Polymeric Microparticles For Relief Of Intractable Cancer-related Pain
Funder
National Health and Medical Research Council
Funding Amount
$796,950.00
Summary
For the 10-30% of patients with advanced cancer who experience intractable pain despite administration of large doses of morphine-like drugs by mouth or injection, more invasive dosing routes may be needed. This project will utilise innovative polymer chemistry to develop bioerodable prolonged-release polymer microparticles to deliver pain-killers into the spinal fluid near to the cells that mediate their actions, with a view to producing prolonged periods of analgesia in these patients.
Determining The Impact Of Opioid Substitution Therapy Upon Mortality And Recidivism Among Prisoners: A 22-year Data Linkage Study
Funder
National Health and Medical Research Council
Funding Amount
$354,114.00
Summary
This study will quantify the impact of opioid substitution therapy (OST; methadone or buprenorphine) on two important outcomes for opioid dependent prisoners: mortality, particularly in the post-release period; and subsequent criminal activity. The study will have almost 600,000 person-years of follow-up over 22 years, allowing fine grained analyses of disadvantaged subpopulations. The study has clear implications for the health of this population, crime reductions, and cost savings.
Pharmaceutical Opioid Prescription For Chronic Pain In Australia: Trajectories Of Prescribing, Risk Of Adverse Events, And Predictors Of Harm
Funder
National Health and Medical Research Council
Funding Amount
$1,086,274.00
Summary
There is concern about rising levels of opioid analgesic prescribing in Australia. This study is important because it will provide evidence about long term outcomes for patients using opioid therapy for chronic non-malignant pain. It will examine prescribing patterns and link them to other health outcomes such as overdose. We will also study patients beginning opioid therapy for chronic pain and follow them up over 2 years to examine outcomes such as pain relief and medication side effects.
Spatial And Temporal Dimensions Of Mu-opioid Receptor Signalling: Implications For The Development Of Tolerance
Funder
National Health and Medical Research Council
Funding Amount
$799,316.00
Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
The Efficacy Of Behavioural Activation Therapy In Treating Depression Among Individuals With Opioid Dependence

Funding Amount
$733,908.00
Summary
Heroin dependence is a chronic relapsing condition, associated with high levels of psychopathology. On entry to treatment at least one quarter of heroin users meet criteria for Major Depression. The co-occurrence of heroin dependence and depression is associated with a range of harms and has been linked to poorer treatment outcomes. Despite this, practical and effective treatment options are scarce. The proposed international collaboration will contribute significantly to understanding of the tr ....Heroin dependence is a chronic relapsing condition, associated with high levels of psychopathology.

TIR Signalling Pathway Pharmacogenomics And Opioid Response: Beyond The Mu Opioid Receptor
Funder
National Health and Medical Research Council
Funding Amount
$246,396.00
Summary
This project will identify why some people respond poorly and others have toxic side effects to the major group of pain relieving medications, the opioids. The basis will be the genetics of the immune system and both acute postoperative and chronic cancer pain patients will be studied in this international pharmacogenetics project.
The Mechanisms Through Which Opiates Cause Gastrointestinal Dysfunction
Funder
National Health and Medical Research Council
Funding Amount
$410,594.00
Summary
Opiates are the mainstay analgesics for severe pain. However, their use in pain relief can be greatly limited due to gut-related side-effects. These include chronic constipation, which is mediated through actions on neurons in the intestine. In this proposal we will examine the role of key proteins, known as beta arrestins, in the generation of opiate-induced constipation. Knowledge derived from this study will facilitate the development of analgesics with fewer gastrointestinal side-effects.
