Gastroparesis Drugs Market By Drug Class (Prokinetic Agents, Antiemetics, Ghrelin Agonists, Tricyclic Antidepressants, Others); By Route of Administration (Oral, Injectable, Transdermal/Sublingual); By Distribution Channel (Hospital Pharmacies, Retail Pharmacies, Online); By Geography, Segment Revenue Estimation, Forecast, 2024–2030

1. Introduction and Strategic Context

The Global Gastroparesis Drugs Market is projected to grow at a 6.8% CAGR, expanding from USD 7.1 billion in 2024 to USD 10.5 billion by 2030, driven by prokinetic drugs, antiemetics, GI motility therapies, diabetic gastroparesis, and specialty GI care, confirms Strategic Market Research.

 

Gastroparesis — a chronic gastric motility disorder that delays stomach emptying — remains both underdiagnosed and undertreated, especially in type 1 and type 2 diabetic populations. While not life-threatening, its long-term impact on quality of life, nutrition, and glycemic control has made it a focal point of gastroenterology and metabolic care.

 

The pharmaceutical response to this condition is still fragmented. A few key drug classes — like prokinetics, antiemetics, and neuromodulators — dominate prescriptions. But most were never approved specifically for gastroparesis. That’s changing. As regulatory bodies push for indication-specific approvals, and as off-label treatment becomes less defensible in payer negotiations, drug developers are returning to this niche.

 

One of the biggest triggers for renewed R&D interest? The rising tide of diabetes-related gastroparesis . With global diabetes prevalence climbing past 500 million cases, gastroenterologists are seeing gastroparesis more often — particularly in women, middle-aged adults, and long-term insulin users. This intersection of metabolic disease and gastric dysfunction is redefining the market’s core.

 

Also, technology is catching up. Smart pill diagnostics, electrogastrography , and high-resolution gastric emptying tests are making diagnosis more precise — and making it easier for clinicians to differentiate gastroparesis from irritable bowel syndrome (IBS) or functional dyspepsia. That’s expanding the addressable patient pool.

 

Meanwhile, pharma innovation is quietly shifting. Pipeline assets like ghrelin receptor agonists and serotonin modulators are entering mid-stage trials. These aren’t just symptom suppressors — they target the root problem: impaired motility and gastric nerve dysfunction. For patients who’ve cycled through domperidone, metoclopramide, or erythromycin without long-term relief, this signals new hope.

 

From a strategic lens, this market sits at the intersection of chronic care , neuromodulation , and GI symptom management . Payers, regulators, and clinical societies are beginning to see gastroparesis not just as a secondary complication, but as a standalone burden deserving targeted therapy.

 

Stakeholders span a wide range — from large pharma players betting on motility agents, to specialty drug developers targeting orphan GI indications, to digital health platforms exploring AI-driven gastroparesis diagnostics.

 

To be honest, this market used to be treated as an afterthought within gastroenterology. That mindset is fading. With real-world data showing higher hospitalization rates, ER visits, and poor glycemic outcomes in untreated patients, there’s now a business case — not just a clinical one — for investing in this space.

Segment-Level Insights and Market Structure – Gastroparesis Drugs Market

The Gastroparesis Drugs Market is organized around distinct therapeutic classes and distribution channels, reflecting variations in symptom severity, underlying etiology, and care-delivery settings. Each segment contributes differently to overall market value, prescribing behavior, and future growth potential, influenced by chronic disease management needs, safety considerations, and evolving clinical practice patterns. As gastroparesis remains a symptom-driven and underdiagnosed condition, segmentation dynamics are shaped as much by tolerability and persistence as by clinical efficacy.

Therapy Type Insights:

Prokinetic Agents

Prokinetic drugs represent the core therapeutic backbone of gastroparesis management, as they directly target delayed gastric emptying—the defining physiological abnormality of the disease. These agents are most commonly used as first-line therapy across diabetic and idiopathic gastroparesis due to their immediate impact on gastric motility. From a market standpoint, prokinetics account for a substantial share of treatment volume, supported by broad prescribing familiarity and outpatient use. However, long-term growth is constrained by safety warnings, monitoring requirements, and limitations on chronic use, gradually reshaping prescribing behavior toward adjunct or alternative therapies.

Antiemetics

Antiemetic therapies occupy a symptom-control-focused segment, primarily addressing nausea and vomiting rather than gastric motility itself. Their use is widespread across disease severities, particularly in patients with frequent exacerbations or poor tolerance to motility agents. Commercially, antiemetics contribute steady but lower-value revenue, as they are often used intermittently or in combination with other drugs. Despite not modifying disease progression, their role remains critical in improving quality of life and preventing hospitalizations, sustaining consistent demand within the therapeutic mix.

Ghrelin Receptor Agonists

Ghrelin-based therapies represent an emerging and innovation-driven segment within the gastroparesis drugs market. These agents aim to restore gastric motility through hormonal pathways, offering a differentiated mechanism compared to dopamine or serotonin-based prokinetics. Although current adoption is limited due to developmental status and restricted availability, this segment carries strong strategic importance. As clinical evidence matures, ghrelin receptor agonists have the potential to redefine treatment standards, particularly in patients who are refractory to existing therapies.

Neuromodulators and Other Agents

This segment includes low-dose neuromodulators, endoscopic interventions, and investigational agents that address visceral hypersensitivity, pain, or refractory symptoms. Their use is typically confined to select patient populations, such as idiopathic gastroparesis or treatment-resistant cases. From a market perspective, these therapies contribute modest revenue but play a disproportionate role in advanced care settings. Continued exploration of novel mechanisms within this category may expand its relevance over time, particularly for symptom-dominant disease presentations.

 

Distribution Channel Insights:

Retail Pharmacies

Retail pharmacies form the primary access channel for gastroparesis drugs used in long-term outpatient management, including oral prokinetics, antiemetics, and neuromodulators. Their importance is driven by chronic prescription refills and continuity of care for stable patients. Market value in this channel is supported by consistent dispensing volume and patient reliance on local pharmacy networks, particularly in regions with established primary and specialty care pathways.

Hospital Pharmacies

Hospital pharmacies play a central role in acute and advanced gastroparesis management, supplying injectable therapies, IV antiemetics, and rescue treatments for severe symptom flares. They are closely integrated with emergency departments, inpatient care, and specialist gastroenterology services. Due to their involvement in high-severity cases and combination therapy use, hospital pharmacies account for a significant share of overall market value despite lower prescription counts relative to retail settings.

Online Pharmacies

Online pharmacies represent a growing but still secondary distribution channel, driven by the chronic nature of gastroparesis and increasing comfort with digital prescription fulfillment. This channel is particularly relevant for patients requiring long-term symptom control who prefer home delivery and subscription-based refills. As telehealth consultations become more common in gastroenterology, online pharmacies are expected to gain incremental importance, especially in regions with limited specialist access.

 

Segment Evolution Perspective

The gastroparesis drugs market is undergoing gradual structural evolution, characterized by a shift from reliance on legacy prokinetics toward more diversified therapeutic strategies. While established drug classes continue to anchor current treatment practices, emerging motility-targeted and mechanism-specific therapies are expected to influence future prescribing patterns. In parallel, distribution channels are adapting to the increasing role of outpatient care, chronic disease management, and digital health integration. Together, these dynamics are likely to reshape how value is distributed across therapy types and access points over the forecast period.

 

Key Approved and Late-Stage Pipeline Therapies for the Gastroparesis Drugs Market

• Reglan® (metoclopramide), administered orally or via injection, remains one of the most established pharmacologic options for gastroparesis management. Originally developed under Wyeth (now part of Pfizer), metoclopramide is FDA-approved in the United States and functions primarily through dopamine D2 receptor antagonism with additional mixed serotonergic effects. This mechanism enhances gastric motility and accelerates gastric emptying, making it a cornerstone first-line therapy, although long-term use is constrained by neurological safety concerns.

• GIMOTI® is a nasal spray formulation of metoclopramide developed and commercialized by Evoke Pharma and approved in the United States specifically for diabetic gastroparesis. By delivering metoclopramide intranasally, GIMOTI bypasses gastrointestinal absorption challenges commonly seen during severe nausea and vomiting episodes. Its mechanism remains D2 receptor antagonism, but the alternative route of administration improves reliability of drug delivery and symptom control in affected patients.

• Domperidone, marketed in some regions under brand names such as Motilium®, is developed by Janssen Pharmaceutica and approved outside the United States, with restricted access domestically. Domperidone acts as a peripheral dopamine D2 receptor antagonist, providing prokinetic benefits with limited central nervous system penetration. While this profile reduces neurological side effects compared to metoclopramide, cardiac QT-prolongation risks continue to limit widespread adoption and regulatory acceptance.

• Low-dose erythromycin is used off-label for gastroparesis as a motility-enhancing agent, with legacy origins at Abbott through the Erythrocin® franchise. Its prokinetic effect is mediated via motilin receptor agonism, which stimulates gastric contractions and accelerates gastric emptying. Although effective in the short term, tachyphylaxis and antimicrobial resistance concerns restrict its long-term clinical utility.

• Zofran® (ondansetron), originally developed by GlaxoSmithKline, is an approved antiemetic frequently used in gastroparesis symptom management. Ondansetron functions through selective 5-HT3 receptor antagonism, reducing nausea and vomiting but without addressing delayed gastric emptying. Its role is therefore supportive rather than disease-modifying, often used in combination with prokinetic agents.

• Kytril® (granisetron), a Roche-originated therapy, is another approved 5-HT3 receptor antagonist utilized for nausea and vomiting control in gastroparesis. Similar to ondansetron, granisetron provides symptomatic relief without correcting underlying motility dysfunction, contributing to quality-of-life improvements rather than direct gastric emptying enhancement.

• Phenergan® (promethazine), originating from Rhône-Poulenc and now part of the Sanofi lineage, is an approved antihistamine used for antiemetic and sedative effects in gastroparesis. Its mechanism involves H1 receptor antagonism with anticholinergic properties, offering symptom relief in patients with severe nausea, although sedation and anticholinergic burden can limit tolerability.

• Tradipitant, developed by Vanda Pharmaceuticals, is a late-stage investigational therapy in Phase III development for gastroparesis. It targets the neurokinin-1 (NK-1) receptor, aiming to modulate central nausea and vomiting pathways. Tradipitant reflects a strategic shift toward symptom-dominant mechanisms rather than direct motility stimulation.

• Relamorelin (RM-131), originally developed by Allergan and later acquired by AbbVie, is a ghrelin receptor agonist designed to stimulate gastric motility. Although it advanced into Phase III clinical trials, development was terminated following strategic reassessment. Despite discontinuation, relamorelin remains an important reference point for ghrelin-based therapeutic innovation in gastroparesis.

• Velusetrag, developed by Theravance Biopharma, is a selective 5-HT4 receptor agonist that has reached Phase II clinical development. Its mechanism promotes gastric emptying through targeted serotonergic stimulation, positioning it as a next-generation prokinetic candidate with improved receptor selectivity compared to older agents.

• Prucalopride, marketed by Takeda for other gastrointestinal indications, has been investigated through clinical repurposing studies in gastroparesis. As a selective 5-HT4 receptor agonist, prucalopride enhances gastrointestinal motility and represents an example of cross-indication expansion rather than a gastroparesis-specific development program.

• BOTOX® (onabotulinumtoxinA), developed by AbbVie through its Allergan franchise, is used off-label via endoscopic pyloric injection in refractory gastroparesis cases. The therapy works by inducing localized neuromuscular blockade to reduce pyloric sphincter tone, facilitating gastric emptying in select patients who fail pharmacologic therapy.

Neurogastrx:

• Phase 2 NG101 (metopimazine mesylate) results published with safety signal emphasis (USA)
  A 2025 publication reported Phase 2 results for NG101 (metopimazine mesylate) in gastroparesis, noting the study’s primary endpoint was not statistically significant versus placebo, but highlighting favorable safety and secondary endpoint improvements, which keeps the asset in play for refinement of dose, population, and endpoints.

Aclipse Therapeutics:

• Mayo Clinic collaboration to advance Phase 2 “disease-modifying” approach (USA)
  Aclipse announced collaboration with Mayo Clinic for Phase 2 development of M107 in gastroparesis, aiming to move beyond symptom-only management toward a potentially disease-modifying positioning (company-stated strategy) and strengthening clinical credibility via major-center trial execution.

 

2. Market Segmentation and Forecast Scope

The gastroparesis drugs market breaks down across several layers — all shaped by the underlying cause of the condition, patient comorbidities, and the risk-benefit tradeoffs of long-term drug use. While prescriptions still rely heavily on a small pool of off-label drugs, segmentation is gradually becoming more structured as new candidates gain traction.

By Drug Class

Prokinetic Agents Still the frontline therapy — especially metoclopramide and domperidone — due to their ability to enhance stomach contractions and accelerate gastric emptying. However, long-term use comes with risks: extrapyramidal symptoms, tardive dyskinesia, and cardiac side effects.

Antiemetics Widely used to manage nausea and vomiting, especially in moderate-to-severe cases. Ondansetron , promethazine , and granisetron remain common, though they don’t address the underlying motility issue.

Ghrelin Receptor Agonists An emerging class that directly stimulates gastric motility. Agents like relamorelin are in clinical trials, and early results show promise in diabetic gastroparesis — potentially displacing prokinetics over time.

Tricyclic Antidepressants (Low Dose) Used off-label for idiopathic gastroparesis to modulate visceral hypersensitivity. Not ideal for diabetics due to glycemic interaction risks.

Other Agents Includes botulinum toxin injections (endoscopic), herbal formulations, and newer investigational drugs like 5-HT4 receptor agonists .

As of 2024, prokinetic agents account for an estimated 41% of the global market revenue , but growth is slowing due to safety concerns. Ghrelin-based drugs — while small in market share — are projected to grow at the fastest CAGR between now and 2030.

 

By Route of Administration

Oral Route Dominant and most convenient for chronic care. Challenges include poor absorption during flare-ups and nausea.

Parenteral / Injectable Reserved for hospitalized patients or those with severe vomiting. IV metoclopramide remains a go-to in ER settings.

Transdermal and Sublingual Still in exploratory stages but gaining interest for patients unable to tolerate oral meds. Some antiemetics and experimental motility drugs are being developed in these formats.

 

By Distribution Channel

Hospital Pharmacies Serve acute care and inpatient settings. Higher usage of IV drugs and off-label antiemetics.

Retail Pharmacies The largest channel by volume, especially for oral prokinetics and tricyclics prescribed in outpatient clinics.

Online Pharmacies Growing steadily, particularly in North America and Asia Pacific. Driven by chronic care patients who refill long-term prescriptions.

 

By Region

North America Largest market. High diabetes prevalence, strong regulatory oversight, and payer interest in reducing ER visits.

Europe Second-largest. Tight reimbursement controls and a push toward EMA-approved agents.

Asia Pacific Fastest-growing, thanks to rising diabetes rates, better diagnostic access, and generic drug expansion.

Latin America, Middle East & Africa (LAMEA) Still underpenetrated. Growth hinges on better diagnosis and pharmacist-driven chronic care models.

Scope Note: Though historically clustered around metoclopramide and domperidone, this market is quietly diversifying. As gastroparesis becomes easier to diagnose and stratify (diabetic vs. idiopathic vs. post-viral), drug makers are crafting more nuanced pipelines and channel strategies.

 

3. Market Trends and Innovation Landscape

The gastroparesis drugs market is moving beyond patchwork prescribing. For years, clinicians treated gastroparesis with borrowed tools — antiemetics for nausea, prokinetics for motility, antidepressants for pain. But that landscape is changing fast. Emerging drug candidates, new diagnostic capabilities, and a clearer clinical profile are reshaping how companies and providers think about this disorder.

1. Pipeline Innovation Is Focused on Specificity, Not Repurposing

Historically, most drugs used for gastroparesis weren’t approved for it. That’s changing. Companies are now pushing indication-specific approvals , particularly for diabetic gastroparesis , the most common subtype.

• Relamorelin , a ghrelin receptor agonist, is in late-stage trials and shows consistent gastric emptying improvement without the neurological side effects seen in metoclopramide.

• Other pipeline agents — including velusetrag (5-HT4 agonist) and camicinal — are targeting motility and neurotransmitter pathways more selectively.

An expert in GI drug development remarked: “We’re finally seeing molecules designed from scratch for gastroparesis, not just retrofitted anti-nausea meds.”

2. Digital Diagnostics Are Expanding the Treatable Pool

Better diagnosis = more treatment. That’s the equation driving diagnostic innovation:

• Wireless motility capsules can now map gastric emptying times without radiation or sedation.

• Electrogastrography (EGG) and high-resolution gastric mapping are enabling clearer stratification of patients — identifying who responds best to which drug class.

This allows companies to pursue companion diagnostics with targeted therapies, a trend common in oncology but now emerging in GI.

3. AI and Real-World Evidence Are Rewriting the Playbook

Big data is finally catching up to gastroparesis. Payers and providers now have access to:

• Claims data linking gastroparesis to hospital readmission spikes in diabetics

• Machine learning tools predicting which patients will respond poorly to prokinetics

This is leading to risk-based prescribing models — where metoclopramide might be avoided in favor of newer drugs in high-risk patients, even if upfront costs are higher.

One Medicaid plan in the U.S. is piloting coverage for newer motility drugs based on EHR-flagged refractory cases. If successful, others may follow.

4. Partnerships Are Driving Focused R&D

This isn’t a high-volume blockbuster market — so drug companies are partnering more:

• Biotechs developing ghrelin modulators are teaming up with gastroenterology device companies to co-develop therapeutic + diagnostic bundles.

• Academic centers are leading trials for botulinum toxin injections and neurostimulation therapies, often funded by NIH or EU health grants.

These aren’t mega-deals, but they’re aligned with the niche, precision-drug nature of gastroparesis care.

5. Alternative Delivery Formats Are Gaining Interest

Given how often gastroparesis causes oral drug intolerance, developers are experimenting with:

• Transdermal patches for nausea control

• Sublingual prokinetic candidates to bypass gastric delays

• Orally disintegrating tablets that dissolve even in hypo-motile stomachs

These innovations don’t just improve adherence — they could expand access for patients stuck between ER visits and trial-and-error therapies.

Bottom line: the gastroparesis drugs market is no longer a graveyard of repurposed pills . R&D is now aiming to treat the root cause, not just manage symptoms. And with diagnostics improving, the right drug for the right patient is finally within reach.

 

4. Competitive Intelligence and Benchmarking

The gastroparesis drugs market isn’t overrun with players — but it’s far from dormant. It’s defined by a few entrenched generics, a handful of mid-stage innovators, and a slow but steady race toward FDA and EMA approvals for targeted therapies. Success here isn’t about scale — it’s about focus, tolerability, and regulatory finesse.

Takeda Pharmaceuticals

Takeda has quietly emerged as a front-runner in motility-focused R&D. The company is advancing a ghrelin receptor agonist ( relamorelin ) that shows promise in diabetic gastroparesis. Unlike earlier agents, relamorelin targets gastric emptying directly and avoids central nervous system exposure — a big win for long-term safety.

Takeda’s edge lies in its gastrointestinal franchise depth , combined with a smart licensing strategy. If trials go well, they may dominate the first FDA-approved drug class built specifically for this condition.

Ipsen

Through its global botulinum toxin portfolio, Ipsen is exploring intra-pyloric injections as a procedural therapy for refractory gastroparesis. Early-stage trials have shown mixed results, but the company continues to partner with academic GI groups in the U.S. and Europe. Their bet? A procedural plus pharmacologic bundle for severe cases.

Neurogastrx

A clinical-stage biotech focused solely on upper GI disorders. Their NG101 candidate , a 5-HT4 receptor agonist, is being developed specifically for idiopathic and diabetic gastroparesis. It’s designed to offer prokinetic action without the cardiovascular risks that derailed similar drugs in the past.

Their focus on trial design optimized for FDA endpoints gives them an advantage in fast-track designation applications. Neurogastrx may become an acquisition target if results hold.

Evoke Pharma

Evoke developed Gimoti , a metoclopramide nasal spray formulation approved in the U.S. for gastroparesis. While the active molecule is well-known, the delivery format offers a useful workaround for patients with poor gastric absorption or vomiting.

The challenge? Reimbursement and physician uptake. That said, Evoke remains one of the only companies with a formally approved, branded treatment in this space — a rarity in a generics-dominated field.

Teva Pharmaceuticals and Other Generics

Teva and other generic manufacturers supply oral metoclopramide , domperidone (in markets where approved) , and antiemetics used off-label. These players dominate volume, but not differentiation. Many hospitals and outpatient clinics still rely on generics for first-line treatment — though that may change as new agents gain market entry.

Competitive Dynamics at a Glance:

• Takeda and Neurogastrx are pushing the innovation frontier with gut-selective prokinetics.

• Evoke is betting on alternative delivery and faster symptom relief.

• Generic makers still control frontline prescribing, but with limited clinical guidance or labeling precision.

• Device-drug combo approaches (Ipsen’s botulinum work, smart diagnostic tie-ins) could redefine what qualifies as a “drug” in this space.

This isn’t a volume war — it’s a credibility game. The companies that prove durable efficacy without intolerable side effects will define the next decade of treatment.

 

5. Regional Landscape and Adoption Outlook

The adoption of gastroparesis drugs varies dramatically across geographies — shaped by diabetes prevalence, healthcare system structure, diagnostic infrastructure, and regulatory nuances. In some regions, the condition is well-characterized and actively treated. In others, it’s underdiagnosed and often confused with broader functional GI disorders.

North America

The U.S. dominates the global market , driven by its high rates of diabetes (particularly type 2) and growing awareness of gastroparesis as a standalone disorder. The presence of FDA-approved options like Gimoti (nasal metoclopramide) , off-label access to domperidone via IND programs, and pipeline trials for relamorelin and NG101 make the U.S. a clear innovation hub.

• Reimbursement is improving, especially for diabetic subtypes with ER visit history

• Academic centers are leading trials that combine AI diagnostics with prokinetic prescriptions

• Canada, while smaller, follows a similar path — though domperidone is more readily available due to regulatory differences

Expect continued leadership from North American players in both R&D and early market approvals.

Europe

Europe is more cautious in its regulatory approach. The European Medicines Agency (EMA) has not approved many targeted drugs for gastroparesis, and prescribers often default to domperidone or erythromycin — despite growing safety concerns. That said, countries like Germany, the UK, and France are slowly incorporating updated guidelines and diagnostic coding for the condition.

• Domperidone is still widely used but under stricter cardiac safety guidelines

• The EU’s Horizon health programs are funding trials for drug-device combinations

• Access remains uneven — southern and eastern European countries lag in both diagnosis and treatment options

Bottom line: strong public health systems, but slow regulatory movement.

Asia Pacific

The fastest-growing market by far — not because of innovation, but sheer volume. India and China are experiencing spikes in diabetic gastroparesis , particularly in urban areas. But diagnosis remains inconsistent, and treatment is often symptomatic rather than targeted.

• India relies heavily on low-cost generics ; prokinetics are sold OTC in many states

• China is expanding hospital infrastructure and supporting local trials, especially in Shanghai and Beijing

• Japan, with its aging population, is exploring non-oral formulations for gastroparesis in elderly diabetic patients

As diagnostic standards improve, expect a surge in branded drug uptake across this region — especially in private healthcare networks.

Latin America, Middle East & Africa (LAMEA)

Still underpenetrated — but not without momentum. In Latin America:

• Brazil and Mexico are beginning to recognize gastroparesis in national diabetes management guidelines

• Access to branded drugs is limited, but local generics fill the gap

• Hospital-based specialists are leading pockets of innovation in tertiary centers

In the Middle East:

• Saudi Arabia and UAE are investing in GI diagnostics as part of broader NCD (non-communicable disease) programs

• Expat populations with Western dietary patterns are increasing demand for targeted motility treatments

Africa is the most underserved. Diagnosis is rare, and most treatments are generalized symptom management. NGO-led telehealth programs and international academic collaborations are beginning to fill knowledge and access gaps.

Key Takeaways by Region:

• North America : Regulatory and innovation leadership, especially for diabetic gastroparesis

• Europe : Conservative on new drug approvals but steady on guideline implementation

• Asia Pacific : Explosive volume, growing private sector demand, and strong generic foothold

• LAMEA : Uneven access but rising awareness and localized momentum in major metros

Regional success won’t come from copy-paste strategies. Drug developers need to tailor pricing, distribution, and even education to match each market’s clinical reality.

 

6. End-User Dynamics and Use Case

The gastroparesis drugs market may be driven by innovation at the top, but the actual adoption happens at the front lines — in outpatient clinics, emergency rooms, endocrinology units, and GI specialty practices. Each type of healthcare provider has a different approach to prescribing, influenced by symptom severity, diagnostic access, and patient compliance.

Hospitals and Emergency Departments

These settings typically handle acute gastroparesis flares — often in diabetic patients who arrive with nausea, vomiting, or bloating. First-line treatment usually involves IV antiemetics or prokinetics , followed by a transition to oral meds upon discharge.

• Metoclopramide remains a workhorse here, despite safety concerns

• Some ERs in the U.S. are piloting rapid gastric emptying scans to differentiate true gastroparesis from functional GI syndromes

• Hospitals also trial new formulations like nasal sprays for patients who can’t tolerate oral meds during acute flares

The main concern? Short-term relief. Hospitals are rarely positioned to manage chronic symptom cycles, so patients are often bounced back into outpatient care without a clear long-term plan.

Specialty Gastroenterology Clinics

This is where most chronic gastroparesis care happens. GI specialists have the diagnostic tools and time to tailor therapy — often combining lifestyle coaching, diet modification, and drug regimens.

• Providers may rotate between tricyclic antidepressants , low-dose prokinetics , and anticholinergics depending on symptom profile

• Clinics also lead enrollment in clinical trials for newer agents like relamorelin or botulinum toxin-based therapy

• They’re more likely to use gastric mapping or wireless motility capsule tests before settling on a drug regimen

These clinics represent the tipping point between empirical treatment and evidence-guided prescribing. They’re also where branded, indication-specific drugs are most likely to gain traction first.

Primary Care and Endocrinology Practices

Often the first to spot symptoms — but rarely equipped to manage them fully. Primary care doctors and endocrinologists may see diabetic patients with unexplained nausea or erratic glucose control, and suspect delayed gastric emptying.

• Many start patients on standard antiemetics or low-dose erythromycin , often off-label

• Referral to GI happens late, usually after failed symptom control

• Education gaps persist — some providers still view gastroparesis as a vague or unfixable condition

This segment is important not because they drive prescription volume — but because they initiate the treatment funnel . Better diagnostic education at this level could expand early drug intervention.

Retail Pharmacies and Online Platforms

These channels handle the majority of long-term refills , especially in regions where prokinetics and antiemetics are available generically or over the counter.

• In the U.S., prescription-only drugs like metoclopramide are filled mainly through retail chains

• In India or Southeast Asia, over-the-counter prokinetics can be picked up without formal diagnosis — which risks inappropriate use, but also reflects demand

• Online pharmacies are growing, especially for chronic users seeking auto-refill models and private delivery

Use Case Highlight

A diabetes specialty clinic in California noticed that a subset of patients with well-controlled HbA1c levels were still reporting frequent bloating and erratic insulin absorption. After implementing wireless motility capsule testing , 28% were found to have moderate to severe gastroparesis.

Instead of defaulting to metoclopramide, the clinic enrolled patients in a trial using a ghrelin receptor agonist . Over six months, patient-reported symptoms declined significantly, and insulin dosing stabilized. Medication adherence also improved thanks to fewer GI side effects.

For providers, the gain wasn’t just better GI outcomes — it was better glycemic control. That changed how they thought about treating “just a stomach problem.”

Bottom line: End-user dynamics in gastroparesis treatment are shifting. Specialty clinics will drive new drug uptake, but primary care and pharmacy networks are where scale happens. The key is closing the loop between diagnosis, symptom control, and chronic care management.

 

7. Recent Developments + Opportunities & Restraints

Recent Developments (Last 2 Years)

• Takeda Pharmaceuticals advanced its Phase III trials for relamorelin , a ghrelin receptor agonist targeting diabetic gastroparesis. Initial data showed improved gastric emptying and reduced nausea with a more favorable side effect profile than traditional prokinetics. If approved, this would be one of the first targeted therapies for this indication.

• Evoke Pharma expanded distribution of Gimoti (metoclopramide nasal spray) in North America through a specialty pharmacy partnership. The goal is to make non-oral formulations more accessible to patients with chronic nausea and oral intolerance.

• Neurogastrx began mid-stage trials for NG101 , a next-gen 5-HT4 agonist designed to reduce cardiac risk while improving GI motility. Early-phase studies suggest reduced bloating and improved gastric accommodation in idiopathic gastroparesis.

• A European biotech initiated clinical evaluation of botulinum toxin injections into the pyloric sphincter as an adjunct therapy. Trials are being run in Germany and the Netherlands, targeting patients with refractory symptoms.

• Multiple academic medical centers in the U.S. adopted AI-based gastric motility assessment tools , enabling more consistent diagnosis of gastroparesis from smart capsule and electrogastrography data — helping refine drug prescribing pathways.

 

Opportunities

• Disease Stratification Creates Precision Drug Pathways As diagnostic tools improve, physicians are starting to classify patients into subtypes (diabetic, idiopathic, post-viral). This makes targeted therapy trials more effective and gives companies a clearer path to approval — with potential for companion diagnostics.

• Innovation in Delivery Formats Nasal sprays, orally disintegrating tablets, and transdermal patches are gaining clinical interest. These bypass the very motility issues that undermine oral drug absorption — offering higher compliance in severe cases.

• Emerging Markets with Growing Diabetic Populations India, China, and Southeast Asia are seeing a rise in gastroparesis incidence, especially among younger diabetic patients. Generic prokinetics dominate, but branded drugs could gain ground through physician training and diagnostic access.

 

Restraints

• Safety Profile Concerns for Existing Drugs Metoclopramide carries black-box warnings in some markets. Domperidone faces regulatory hurdles in the U.S. This limits long-term use and discourages prescribing in milder cases.

• Lack of Diagnostic Standardization In many regions, gastroparesis is either misdiagnosed or lumped into “functional dyspepsia.” Without accurate tests like smart capsules or gastric emptying scans, treatment remains symptomatic and generic.

To be honest, the biggest challenge isn’t drug efficacy — it’s identification. A large swath of patients are likely suffering from undiagnosed or mismanaged gastroparesis. That’s both a limitation and an opportunity, depending on who moves first with the right solution.
