ACOTIAMATE 100 & Acotiamide (100mg ER): Uses, Dosage, Side Effects, Price, Composition and more.........

What Is Acotiamide 100 mg?

Acotiamide 100 mg is a gastrointestinal medicine containing 100 mg of acotiamide as its active ingredient.

It is primarily used to manage symptoms of functional dyspepsia (FD). Functional dyspepsia is a disorder characterized by persistent or recurrent upper-digestive symptoms such as uncomfortable fullness after eating, early satiety, upper-abdominal discomfort and bloating.

Indian product listings describe Acotiamide 100 mg as being used for indigestion and associated symptoms including bloating after meals, upper-abdominal pain and early satiety.

Acotiamide is not simply another antacid. Its principal action involves the motility and accommodation of the upper gastrointestinal tract, which makes it particularly relevant when symptoms are related to eating and impaired gastric function.

Acotiamide Tablets 100mg How to Use 

The primary Acotiamide 100 mg use is the management of symptoms associated with functional dyspepsia.

1. Functional Dyspepsia

Acotiamide is particularly associated with functional dyspepsia in patients who have troublesome upper-digestive symptoms without an adequate structural explanation for those symptoms.

The 2026 Second Asian Consensus Report on Functional Dyspepsia states that fundic-relaxant medicines such as acotiamide may be effective in improving functional dyspepsia, particularly postprandial distress syndrome (PDS).

2. Indigestion

Acotiamide 100 mg may be prescribed for persistent indigestion when the symptoms fit functional dyspepsia.

3. Post-Meal Bloating

If bloating becomes particularly uncomfortable after meals, acotiamide may be considered as part of a treatment plan.

4. Early Satiety

Early satiety means feeling full after eating a relatively small amount of food. This is a characteristic symptom of the PDS subtype of functional dyspepsia.

5. Postprandial Fullness

Postprandial fullness refers to an uncomfortable feeling of prolonged fullness after eating.

This is one of the symptoms for which acotiamide has been clinically studied.

6. Upper-Abdominal Discomfort

Acotiamide may also be prescribed when functional dyspepsia causes discomfort or pain in the upper abdomen.

How Does Acotiamide 100 mg Work?

Acotiamide works differently from medicines that directly reduce stomach acid.

It influences gastrointestinal nerve signaling, including acetylcholine-related pathways, and can improve aspects of gastric motor function and gastric accommodation.

In simple terms:

Acotiamide → influences gastrointestinal signaling → supports stomach motility/accommodation → may reduce meal-related fullness, bloating and dyspeptic symptoms.

Acotiamide is categorized in recent Asian consensus recommendations as a fundic relaxant. These medicines are intended to improve relaxation of the upper stomach, particularly in people experiencing postprandial fullness.

This mechanism helps explain why acotiamide may be more relevant for meal-related functional-dyspepsia symptoms than for ordinary acid-related heartburn.

Key Benefits of Acotiamide 100 mg

1. Helps Manage Functional Dyspepsia

The most important potential benefit of Acotiamide 100 mg is improvement in symptoms associated with functional dyspepsia.

A systematic review summarized in the 2026 Asian Consensus Report found acotiamide to be more effective than placebo for overall functional-dyspepsia symptom improvement across the included randomized trials.

2. May Reduce Postprandial Fullness

Acotiamide has been specifically investigated for meal-related symptoms.

In a phase III placebo-controlled trial, 100 mg acotiamide was administered three times daily for four weeks and produced better overall treatment response than placebo.

3. May Help With Early Satiety

For patients who feel unusually full after eating only a small amount, acotiamide may help when the underlying symptoms are consistent with functional dyspepsia.

4. May Improve Upper-Abdominal Bloating

Upper-abdominal bloating is another meal-related symptom for which acotiamide has been studied.

5. May Improve Overall Digestive Comfort

Clinical research has reported improvement in multiple functional-dyspepsia symptoms and quality-of-life measures in appropriately selected patients.

What the evidence says

A phase III randomized trial involving 100 mg acotiamide found that 52.2% of patients receiving acotiamide versus 34.8% receiving placebo were classified as responders according to the study's overall treatment-efficacy assessment after four weeks. The study also found greater elimination of the three key meal-related symptoms—postprandial fullness, upper-abdominal bloating and early satiety—with acotiamide than placebo.

That does not mean every patient will experience the same response, but it provides clinically relevant evidence for its use in functional dyspepsia.

Acotiamide 100 mg Dosage: How Is It Taken?

The correct Acotiamide 100 mg dosage should be determined by the prescribing physician.

Clinical studies of the 100 mg immediate-release formulation commonly evaluated 100 mg three times daily, generally before meals. A dose-ranging study identified 100 mg three times daily as an effective studied regimen for functional dyspepsia.

However, do not automatically follow a clinical-trial dose as your personal prescription.

Your dosage can depend on:

• Your diagnosis
• Severity of symptoms
• Product formulation
• Other medicines you take
• Medical history
• Doctor's treatment plan

Current Indian product listings commonly instruct patients to take Acotiamide 100 mg before meals, for the duration advised by the doctor.

Important dosage precautions

• Take the medicine exactly as prescribed.
• Do not take more tablets to obtain faster relief.
• Do not change from 100 mg to 300 mg on your own.
• Do not substitute immediate-release and extended-release formulations without professional advice.
• If you miss a dose, follow the instructions provided by your doctor or pharmacist rather than doubling the next dose.

Acotiamide 100 mg Side Effects

Like any prescription medicine, Acotiamide 100 mg may cause side effects.

Reported or recognized adverse effects include:

• Headache
• Diarrhea
• Constipation
• Nausea
• Abdominal discomfort
• Dizziness
• Skin rash or itching

The 2026 Asian Consensus Report specifically lists headache and diarrhea among adverse effects associated with acotiamide.

In clinical studies, overall adverse-event rates have generally been comparable with placebo, although individual patients can experience unwanted effects. A phase III trial reported no significant cardiovascular effects attributable to acotiamide treatment.

When should you contact a doctor?

Contact a healthcare professional if side effects are severe, persistent or getting worse.

Seek prompt medical evaluation if indigestion is accompanied by:

• Black or bloody stools
• Repeated vomiting
• Severe or persistent abdominal pain
• Difficulty swallowing
• Unexplained weight loss
• Persistent fever
• Severe weakness or dehydration

These symptoms may indicate an underlying condition that requires investigation rather than treatment as uncomplicated functional dyspepsia.

Who Should Take Acotiamide 100 mg With Caution?

Tell your doctor if you have:

• Liver disease
• Kidney disease
• A history of significant gastrointestinal illness
• Drug allergies
• Pregnancy or plans to become pregnant
• Breastfeeding
• Other prescription or non-prescription medicines

Do not self-medicate simply because your symptoms resemble indigestion.

The correct diagnosis matters because upper-abdominal symptoms can occur with several conditions, including gastroesophageal reflux disease, peptic ulcer disease, gallbladder disease, H. pylori infection and other gastrointestinal disorders.

Acotiamide 100 mg Drug Interactions

Before starting treatment, tell your doctor or pharmacist about all medicines, supplements and herbal products you use.

Acotiamide affects cholinergic pathways in the gastrointestinal tract, so medicines that influence anticholinergic activity may be clinically relevant.

Do not assume that an over-the-counter digestive medicine is automatically safe to combine with Acotiamide 100 mg.

If you are taking several medicines, ask a pharmacist to check the complete combination.

Acotiamide 100 mg vs Antacid

Acotiamide 100 mg is not an antacid.

The difference is important:

Acotiamide 100 mg	Antacid
Primarily affects gastrointestinal motility/function	Neutralizes stomach acid
Used mainly for functional dyspepsia	Commonly used for acid-related symptoms
Particularly relevant to post-meal fullness and early satiety	Commonly used for occasional heartburn
Prescription medicine	Some products are available without prescription

If your main complaint is heartburn, acid regurgitation or burning behind the breastbone, you may need a different evaluation and treatment approach.

Acotiamide 100 mg Clinical Evidence

Acotiamide 100 mg has been evaluated in multiple clinical trials involving functional dyspepsia.

A placebo-controlled phase III study evaluated 100 mg three times daily for four weeks. Acotiamide produced a significantly higher overall treatment response than placebo and improved the combined meal-related symptoms of postprandial fullness, upper-abdominal bloating and early satiety.

Another phase III study compared acotiamide 100 mg three times daily with mosapride in patients with meal-related postprandial distress syndrome. The trial found high response rates in both groups and evaluated symptom relief, quality of life and safety.

More recent evidence remains supportive. The Second Asian Consensus Report on Functional Dyspepsia, published in 2026, concludes that fundic relaxants such as acotiamide may be effective, especially for PDS, with moderate-quality evidence.

At the same time, international guidelines emphasize that the strength of evidence varies between prokinetic medicines and that treatment should be individualized.

Conclusion: Is Acotiamide 100 mg Right for You?

Acotiamide 100 mg is a prescription medicine primarily used for functional dyspepsia, especially when symptoms include post-meal fullness, early satiety, upper-abdominal bloating and indigestion.

Its mechanism differs from that of antacids and acid-suppressing medicines because acotiamide works primarily through gastrointestinal neurotransmission and stomach motor function. Clinical evidence supports its use for meal-related functional-dyspepsia symptoms, and the latest Asian consensus recommendations continue to recognize acotiamide as a potentially effective option, particularly for postprandial distress syndrome.

The 100 mg formulation has been extensively studied at 100 mg three times daily, usually administered before meals in clinical trials. However, your personal dose should always come from your doctor because the correct regimen depends on your specific product and clinical circumstances.

Possible Acotiamide 100 mg side effects include headache and diarrhea, with other digestive or skin-related reactions possible. Persistent, severe or unusual symptoms should be evaluated by a healthcare professional.

Most importantly, Acotiamide 100 mg is not a universal treatment for every type of indigestion. If symptoms persist or occur alongside warning signs such as unexplained weight loss, gastrointestinal bleeding, difficulty swallowing or repeated vomiting, medical evaluation is important.
