Understanding the 'New Gel' for IBS: Enterosorbents
Many patients with Irritable Bowel Syndrome (IBS) seek effective treatments. The 'new gel' for IBS refers to enterosorbents, non-pharmacological medical devices like Silicolgel and Enterosgel that work locally in the gut to bind and remove substances contributing to symptoms. Unlike traditional drugs absorbed systemically, enterosorbents are excreted with attached toxins, offering a generally well-tolerated option.
How Enterosorbent Gels Work
Enterosorbents have a porous structure and large surface area, acting like a 'sponge' in the gastrointestinal tract to adsorb medium-sized molecules such as pathogens, bacterial toxins, and bile acids. This process can help with improving stool consistency and reducing abdominal pain and bloating by binding excess water and irritants. Their physical action means they don't typically interfere with nutrient absorption, providing a gentler approach to gut health management.
Notable Enterosorbent Gels for IBS
Silicolgel and Enterosgel are two examples of enterosorbent gels with supporting clinical trial data.
Silicolgel (Colloidal Silicic Acid)
A 2025 study in Neurogastroenterology & Motility reported positive findings for Silicolgel in patients with IBS-D and IBS-M. A significant majority (91.67%) of patients using Silicolgel showed clinically meaningful improvement in their IBS symptoms after four weeks, compared to a smaller percentage (20%) in the placebo group. The gel binds to irritants and gases, leading to notable reductions in abdominal pain, distension, and bloating. Silicolgel is an over-the-counter medical device available in many areas.
Enterosgel (Polymethylsiloxane Polyhydrate)
Enterosgel has also shown effectiveness for diarrhea-related IBS symptoms, supported by a 2022 randomized controlled trial published in Gut. The study indicated that patients with IBS-D experienced substantial improvements in several symptoms, including abdominal pain, stool consistency, bloating, and urgency, when compared to a placebo. Like Silicolgel, it functions as an intestinal adsorbent, selectively removing harmful molecules from the gut. Enterosgel is an over-the-counter medical device recognized as a treatment option for IBS-D.
Comparison of New Gels vs. Traditional IBS-D Medications
| Feature | Enterosorbent Gels (e.g., Silicolgel, Enterosgel) | Traditional IBS-D Medications (e.g., Viberzi, Xifaxan) |
|---|---|---|
| Mechanism of Action | Physical adsorption of toxins and irritants within the gut. | Pharmacological effects, such as opioid receptor agonism (Viberzi) or antimicrobial action (Xifaxan). |
| Systemic Absorption | Not absorbed into the bloodstream; acts locally. | Absorbed into the bloodstream to produce systemic effects, though some have limited systemic absorption. |
| Classification | Medical devices; not considered pharmacological drugs. | Prescription medications regulated as drugs. |
| Targeted Subtype | Effective for IBS-D and IBS-M. | Typically prescribed for moderate to severe IBS-D. |
| Side Effects | Generally mild and limited to the GI tract (e.g., constipation if overused). | Can have more significant or systemic side effects, such as pancreatitis with Viberzi. |
| Availability | Available over-the-counter in many countries. | Requires a prescription. |
A Broader Look at Innovative IBS Treatments
The range of IBS treatments is expanding beyond traditional drugs. Alongside enterosorbent gels, other innovative therapies are emerging.
- IB-STIM: This is a non-surgical device that uses percutaneous electrical nerve field stimulation (PENFS) to send electrical impulses to cranial nerves, influencing brain areas involved in pain. It is approved for adolescents (8-21) with functional abdominal pain related to IBS. This is a device, not a gel, that addresses the gut-brain connection.
- Microbiome-Targeting Therapies: Companies are developing products, such as EnteroBiotix's EBX-102-02, to help rebalance gut bacteria in patients with IBS-C and IBS-D.
- Novel Neuromodulators: Research is exploring new drugs, like opioid delta-receptor (DOP) agonists, that target the central nervous system to potentially ease IBS symptoms linked to psychological stress.
Conclusion
Enterosorbents are a class of non-pharmacological medical devices representing a new gel for IBS. Research supports their use in managing IBS-D and IBS-M symptoms. These gels offer a new option for patients seeking alternatives to traditional drug treatments. Consulting a healthcare provider is recommended to determine suitability.

Key takeaways
- Not a Traditional Drug: Enterosorbent gels for IBS are classified as non-pharmacological medical devices.
- Physical Mechanism of Action: These gels work by physically binding to harmful substances in the gut.
- Effective for IBS-D and IBS-M: Clinical trials show symptom improvement in patients with these types of IBS.
- High Safety Profile: They are generally well-tolerated with fewer reported side effects compared to some prescription medications.
- Alternative to Traditional Drugs: They provide a new treatment option for patients seeking alternatives to pharmacological interventions.
