Thousands of Australians struggle with serious mental health conditions. Antipsychotic medications, a common treatment for conditions such as schizophrenia and bipolar disorder, often come with severe side effects, the most prominent being significant weight gain. This added burden complicates an already challenging diagnosis, affecting patients’ overall health and well-being.
Recent groundbreaking research from the University of South Australia (UniSA) promises a solution to this pervasive issue. The study, funded by the Hospital Research Foundation (THRF) Group, has shown that antipsychotic drugs can be reformulated with a specially engineered coating. This innovative coating not only prevents unwanted weight gain but also enhances serotonin levels by over 250%.
The researchers concentrated on Lurasidone, a drug widely used to treat schizophrenia and bipolar depression. The new formulation targets the gut microbiome, enhancing drug absorption by eight times while mitigating common side effects such as weight gain.
The success of this approach lies in the unique composition of the coatings. These coatings are created from core-shell particles made of inulin, a dietary fiber, and bioactive medium-chain triglycerides (MCTs). Inulin acts as an energy source for gut bacteria, boosting the gut microbiome. Meanwhile, MCTs facilitate efficient drug absorption into the bloodstream.
Dr. Paul Joyce, the lead researcher from UniSA, explains the significance of the gut microbiome in regulating overall health, particularly mood and cognition. Antipsychotic medications often disrupt this delicate microbial ecosystem, leading to adverse effects such as weight gain. This weight gain can be substantial, with many patients experiencing a 10-15% increase in body weight within just three months of treatment.
The negative impact on the gut microbiome can make these medications counterproductive, as they can lead to a cycle of poor mental and metabolic health. Patients not only have to deal with their original mental health issues but also with the added burden of weight gain and its associated health problems.
Another challenge with current antipsychotic medications is the need to consume them with food to maximize their effectiveness. This requirement can be particularly difficult for a vulnerable patient population, often leading to suboptimal drug levels and reduced efficacy.
The new smart core-shell microparticles developed by the UniSA team address these issues. When antipsychotic drugs are formulated with these microparticles, drug absorption improves significantly. This advancement eliminates the need for patients to take their medication with food, making treatment more manageable and effective. Moreover, the enhanced gut microbiome diversity and abundance help counteract common side effects like weight gain.
This breakthrough has the potential to revolutionize mental health treatments globally. Since the research involves reformulating existing drugs rather than developing new ones, these new therapies can be fast-tracked for clinical use. This means that patients could benefit from these advancements within a few years, rather than the typical 10-15 years required for new drug approvals by regulatory bodies.
The next steps involve testing the efficacy of these reformulated therapies in human patients. The longer-term goal is to extend these technologies across all mental health therapies, including antidepressants, to mitigate adverse effects.
The research from UniSA represents a significant advancement in the treatment of serious mental health conditions. By addressing the side effects of antipsychotic medications, particularly weight gain, and enhancing drug absorption and efficacy, this breakthrough has the potential to improve the lives of millions of people worldwide. As the research progresses, it holds the promise of more effective and manageable treatments for those struggling with mental health disorders, offering hope for a better quality of life.
