Introduction

Constipation is a surprisingly common yet chronically under-discussed health concern. Affecting nearly one in five adults globally, and disproportionately impacting the elderly, diabetic, and comorbid populations, it is often brushed off as a minor complaint. But for many patients, constipation isn’t just discomfort—it’s a daily struggle that affects appetite, sleep, mood, and overall quality of life.

Despite having an arsenal of conventional laxatives, many physicians and patients still feel limited. Current treatments often fall short in long-term efficacy, tolerability, and patient satisfaction. Enter Elobixibat—a novel, bile acid-based approach that offers new hope for patients with chronic constipation, especially those with comorbidities.

The Problem with Current Constipation Therapies

Traditional constipation treatments can be broadly classified into bulk-forming agents, osmotic laxatives, stimulant laxatives, secretagogues, and prokinetics. While each plays a role, they come with limitations:

• Single Mechanism of Action: Most laxatives either soften the stool or stimulate motility—but not both. For example, polyethylene glycol increases water content in the stool, while prucalopride stimulates colonic contractions. But few do both effectively.
• Tolerance and Dependency: Chronic use of stimulant laxatives like bisacodyl or senna can lead to dependency and a “lazy colon,” especially with unsupervised long-term use.
• Side Effects and Dropouts: More than 50% of patients discontinue treatment due to adverse effects like bloating, cramps, or diarrhea.
• Caution in Comorbidities: Lactulose can worsen bloating; magnesium-containing agents like milk of magnesia are unsuitable in chronic kidney disease (CKD); prucalopride requires caution in psychiatric illness and renal impairment.
• Low Satisfaction: Studies reveal that nearly half of patients remain unsatisfied with current constipation therapies—even after trying multiple options.

Elobixibat: A Novel Mechanism, A Fresh Perspective

Elobixibat is a first-in-class partial ileal bile acid transporter (IBAT) inhibitor, developed specifically for chronic constipation. It works by increasing the flow of bile acids into the colon, which enhances:

• Colonic motility
• Fluid secretion
• Rectal sensitivity and the desire to defecate

What makes it especially exciting?

• Acts Locally in the gastrointestinal tract with minimal systemic absorption
• Does not affect the gut microbiota or induce drug resistance
• Works within 24 hours, with effects sustained over 52 weeks in clinical trials

Safe for long-term use in the elderly, diabetics, CKD patients, and even those with oncological or neurological conditions
