Innovative researchers at the University of Queensland have made significant strides in developing a groundbreaking class of oral painkillers designed specifically to alleviate chronic abdominal pain. These new pain management solutions are uniquely derived from the peptide hormone oxytocin, a hormone widely recognized for its vital role in driving contractions during childbirth.
Associate Professor Markus Muttenthaler, who is based at UQ’s prestigious Institute for Molecular Bioscience, spearheaded a talented team that successfully modified the chemical structure of oxytocin. This alteration was essential to enhance the hormone’s stability within the gastrointestinal tract after earlier studies underscored its potential effectiveness in treating abdominal pain.
Dr. Muttenthaler stressed the pressing demand for novel therapies to tackle the debilitating chronic pain that frequently arises from gastrointestinal conditions like irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD).
Chronic abdominal pain impacts approximately 15 percent of adults at some point in their lives. Current treatment options remain limited to anti-inflammatories and opioids, both of which can introduce undesirable side effects and the risk of addiction.
Given these challenges, our research emphasizes the potential of peptides that are not only highly potent and selective but also exhibit minimal side effects. Traditionally, peptide-based medications require injections since they are quickly degraded in the gastrointestinal system.
Now, we have pioneered a technique that renders peptides stable in the gut, facilitating their administration in oral form.
This innovative approach holds tremendous promise for the treatment of various gut-related disorders.

Oxytocin serves as a multifaceted peptide hormone synthesized in the brain and is commonly referred to as the ‘bonding hormone’ or ‘love molecule’ due to its influential role in cultivating relationships, empathy, and trust among individuals.
Additionally, oxytocin is instrumental in triggering uterine contractions during labor and facilitating milk release during breastfeeding, showcasing its critical physiological functions.
In their research, Dr. Muttenthaler and his team pinpointed the specific components of oxytocin that are swiftly decomposed by gastrointestinal enzymes. By employing advanced medicinal chemistry techniques, they successfully modified these components to ensure the new derivative maintains its efficacy at activating the oxytocin receptor while remaining stable in the digestive system.
The outcome of these efforts is the creation of a new class of molecules that possess considerable potency but are resilient against degradation in both the stomach and intestine, thus permitting oral administration.
Moreover, the research findings indicate that these novel molecules primarily exert their effects in the colon and do not require absorption into the bloodstream to alleviate abdominal pain.
This represents a remarkably safe therapeutic strategy, as it significantly minimizes the likelihood of side effects affecting other areas of the body—a common complication associated with many conventional systemic drugs,” Dr. Muttenthaler remarked.
“The advent of this treatment heralds an exciting new mechanism for pain management.
We are actively seeking investors to expedite pre-clinical studies aimed at advancing this promising medication into clinical settings.
With our recent achievements in stabilizing peptides, we are now turning our attention to other gastrointestinal drugs that can enhance therapeutic options for a variety of gut-related disorders, addressing a crucial unmet medical need.”
The findings from this groundbreaking research have been published in the esteemed journal Angewandte Chemie.

Oxytocin: From Love Hormone to Painkiller? | A Cheeky Look
So, apparently, the University of Queensland has decided to play matchmaker between love and science. They’ve taken oxytocin, the so-called “bonding hormone”—you know, the one responsible for making you feel all warm and fuzzy when you’re holding hands with your crush—and turned it into a potential painkiller for chronic abdominal pain. Quite the leap, right? You go from cuddles to contractions to conquering chronic pain. If only it worked on my love life as easily!
Oxytocin and Pain Management: The New ‘Peptide Perfect’?
Associate Professor Markus Muttenthaler and his team have done something that sounds like it belongs in a sci-fi movie: they’ve modified oxytocin’s chemical structure to make it stable in the gut. This is akin to transforming a soufflé into a hard biscuit—just as delicate, but far less likely to collapse! Now, they are hoping to serve this new concoction as an oral painkiller for conditions like irritable bowel syndrome (IBS) and irritable bowel diseases (IBD).
“This pain affects up to 15% of adults in their lifetime, and all we have are anti-inflammatories and opioids which can cause side effects and addiction.”
Ah yes, good ol’ anti-inflammatories… the ultimate “take two and call me in the morning” solution, but with a side of potential addiction. It’s like trying to solve a Rubik’s Cube blindfolded. One wrong move and you could end up with a chronic problem worse than the one you started with!
Potent Peptides: The New Class of Painkillers
Dr. Muttenthaler bluntly states the obvious: want to treat abdominal pain? The existing options are woefully inadequate. So, they’ve hit upon a breakthrough: peptides that are “highly potent and selective,” which apparently makes them a culinary delight for your gut. But before you start dreaming of a magic pill that solves all your woes, let’s break down the science.
All too often, peptide drugs need injections because they tend to disappear faster than your willpower at an all-you-can-eat buffet. Thanks to Muttenthaler’s wizards in the lab, these newly crafted peptides are sturdy enough to tackle the stomach acids of doom, making them suitable for oral administration. If only my diet pills could do the same!
“This is a very safe therapeutic approach as it reduces the risk of side effects in the rest of the body, a problem with many other systemic drugs.”
The Peptide Revolution: Imagine Less Pain and More Cake
Now, the cherry on top of this innovation cake is that these molecules don’t need to cross the gut barrier to work their magic. They go straight to the colon, where they do their thing without leaving a trace. Talk about a one-way ticket to AbdomenVille!
“This is an exciting new mode of action to prevent pain.”
In simple terms: you could potentially pop a pill and bypass all the side effects that come with traditional pain management while keeping your dance card free from embarrassing bathroom trips. Muttenthaler is currently looking for investors to fund these pre-clinical studies. Fingers crossed, right? Because nothing screams “scientific breakthrough” like a bunch of investors waving dollars around!
Final Thoughts: Why Not Just Hug It Out?
So, as the world presses forward with this new development, one has to question the age-old adage: Is it truly love that heals all wounds? Or is it an oxytocin-infused painkiller that can save us from another miserable bathroom break while dealing with chronic pain? For now, we’ll have to wait for the clinical trials—because if there’s one thing we’ve learned about science, it’s that it’s all about the waiting game!
Until then, keep those hugs coming. You never know—they might just be the next big thing in pain relief!
