What is Stugil? (Definition and Classification)

Stugil is a Fixed-Dose Combination Medication (FDC), defined as an Antivertigo agent and an Antiemetic drug, containing two distinct active ingredients in a single oral tablet. This preparation is entirely synthetic in origin and is clinically recognized for its targeted application in managing the complex symptoms of balance disorders. The key differentiating factor of Stugil is its dual-action composition, which is specifically designed to provide a comprehensive and robust support strategy for symptoms such as inner ear disturbances or motion sickness.

Stugil's Composition: Cinnarizine and Domperidone

The two active ingredients are the International Nonproprietary Names (INN) Cinnarizine and Domperidone. Cinnarizine is classified as a first-generation H₁ receptor antagonist and a mild Calcium Channel Blocker, primarily focusing on stabilizing the inner ear's vestibular system. Domperidone, by contrast, is a selective dopamine antagonist and a Gastroprokinetic agent whose effect is largely peripheral, limiting interaction with the central nervous system.

The final tablet form utilizes the unique properties of each ingredient: the vestibular system stabilization provided by Cinnarizine is complemented by Domperidone's efficiency in controlling the vomiting reflex, ensuring the composition is optimized for a dual therapeutic effect.

General Purpose and Dual-Action Benefit

The general therapeutic purpose of Stugil is to provide relief for patients experiencing debilitating symptoms associated with poor balance. A common neutral use scenario involves relieving intense feelings of vertigo and dizziness that are compounded by severe nausea and vomiting. The dual-action benefit stems from the complementary synergistic effect of the two components.

By performing both a labyrinthine suppressant action on the balance mechanism and a peripheral action on the sickness center, the product targets the two primary uncomfortable symptom clusters simultaneously. This design aims to offer efficient, broad-spectrum relief from the immediate and disruptive effects of disequilibrium.

What side effects are possible with Stugil?

Possible side effects and safety information

Official regulatory documents classify the potential side effects of this medication, which contains Cinnarizine and Domperidone, according to frequency and the body systems involved.

Frequency-Classified Adverse Reactions

Adverse reactions listed as Common (affecting up to 1 in 10 people) typically include somnolence, dry mouth, headache, and weight increase. Reactions listed as Uncommon (ge 1/1,000 to < 1/100) may involve mild gastrointestinal symptoms or anxiety. The regulatory profile also lists effects where the frequency is Not Known, such as photosensitivity reactions.

System-Organ Classes and Serious Adverse Reactions

The documented side effects affect several System-Organ Classes, most prominently Nervous System Disorders (e.g., drowsiness, extrapyramidal symptoms) and Gastrointestinal Disorders. Of significant regulatory concern are Cardiac Disorders, where the label explicitly documents the rare but serious risks of QTc prolongation and Ventricular Arrhythmias, including Sudden Cardiac Death, primarily associated with the Domperidone component.

Population-Specific Safety Considerations

The official safety information highlights specific constraints for certain populations. The risk of serious ventricular arrhythmias may be higher in older adults. Furthermore, the use of this medicine is restricted, or contraindicated, in patients with moderate to severe hepatic impairment and those with pre-existing cardiac conditions or gastrointestinal perforation/hemorrhage. Extrapyramidal symptoms are noted to be more frequently observed in older patients during long-term use.

Overdose and Emergency Response

Overdose and When to Seek Help

The official overdose profile for Stugil (Cinnarizine and Domperidone) is defined by the dual risk of central nervous system (CNS) toxicity and life-threatening cardiac complications, which mandates immediate medical intervention.


Documented Overdose Manifestations

Physiological System Officially Documented Signs
Cardiovascular Ventricular arrhythmias, QT interval prolongation, and risk of sudden cardiac death are documented outcomes, primarily due to the Domperidone component.
Neurological Altered consciousness, progressing from somnolence and stupor to coma, seizures (especially in young children), and extrapyramidal symptoms.

Required Emergency Actions and Management

Regulatory authorities mandate that if an overdose is suspected, or if symptoms such as an irregular heartbeat, fainting, or severe neurological changes occur, you must seek immediate medical attention and contact a poison control centre.

  • Antidote Status: No specific antidote is known for overdose of Cinnarizine or Domperidone; therefore, management is symptomatic and supportive care.
  • Monitoring: Continuous ECG monitoring is required to assess and manage the risk of cardiac electrical changes (QT prolongation).
  • Special Populations: The risk of serious ventricular arrhythmias is observed to be higher in patients older than 60 years, and severe neurological complications, including seizures, are noted in young children.

Therapeutic Uses of Stugil

Supportive Management of Acute Vestibular Symptoms

The combination is relevant in clinical settings that involve acute or unstable symptom patterns, primarily addressing core issues stemming from disequilibrium and associated discomfort. It is commonly used across conditions presenting with acute episodes, helping to manage symptoms that interfere with daily functioning, such as those related to vestibular disorders.

The antivertigo component is commonly used to ease symptoms related to inner ear problems. The medication plays a role in managing symptoms that may become intense or disruptive, including severe vertigo, the associated nausea, and the reflex of vomiting. It is also applied in addressing the acute discomfort of motion sickness or travel sickness when supportive symptom management is appropriate.

“The primary goal is to provide supportive relief during difficult episodes by easing the overall symptom load.”

The dual components contribute to improved comfort during periods of heightened symptoms and assist with maintaining functional stability when symptoms are more noticeable.


Quick Fact: Support for Dizziness and Sickness The combination is designed to help patients cope more steadily with the concurrent presence of spinning sensations and sickness that often accompany inner ear disturbances.

Eligibility and Restrictions for Use

Who can and cannot use Stugil?

Official regulatory documents define strict population eligibility for Stugil (Cinnarizine and Domperidone combination), primarily due to cardiac risks associated with the Domperidone component.

Eligibility Status Excluded Population/Condition
Contraindicated Patients with underlying cardiac diseases (e.g., congestive heart failure), QTc prolongation, or significant electrolyte disturbances.
Contraindicated Patients with moderate or severe hepatic impairment or a Prolactin-releasing Pituitary Tumour.
Contraindicated Individuals with gastrointestinal haemorrhage, mechanical obstruction, or perforation.
Not Recommended Children younger than 12 years of age or those weighing less than 35 kg.

Use is restricted in several other groups. Caution is required for patients older than 60 years due to a documented increased risk of serious ventricular arrhythmias. For patients with severe renal impairment, official labeling mandates that the dosing frequency must be reduced. Use during pregnancy is not advisable, and use during lactation requires a decision to discontinue the drug or breastfeeding, as the Domperidone component is excreted in human milk.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Stugil, a combination of Cinnarizine and Domperidone, has officially documented interaction profiles primarily governed by the metabolic and pharmacodynamic properties of its two active ingredients.

Contraindicated Combinations

Co-administration is strictly restricted with two major classes of medicines due to serious risks:

  • Potent CYP3A4 Inhibitors: Prohibited because they significantly increase the plasma concentration and exposure (AUC) of Domperidone, raising the risk of cardiac events. Examples include certain systemic azole antifungals and specific macrolide antibiotics.
  • QTc-Prolonging Medicinal Products: Prohibited due to the additive risk of QTc prolongation and serious ventricular arrhythmia. This includes specific antiarrhythmics and certain antipsychotics.

Pharmacodynamic and Metabolic Interactions

Interaction Type Interacting Substances/Conditions
Additive Sedative Effect CNS depressants (including alcohol) and other central nervous system depressant agents due to the Cinnarizine component.
Absorption Alteration Gastric Acidity Reducers (e.g., Cimetidine, PPIs) impair the oral bioavailability of Domperidone.
Population Restriction Moderate or Severe Hepatic Impairment is a contraindication due to the risk of drug accumulation.

Co-administration with other anticholinergic drugs may result in an additive antimuscarinic action. Due to the absorption alteration, the product should preferably be taken after meals to diminish gastric irritation.

Mechanism of Action

Modulating Vestibular & Central Balance Signals

This domain centers on the Cinnarizine component's action as a calcium channel blocker and H1 histamine receptor antagonist. By reducing calcium influx into inner ear sensory cells and influencing signals in the brain's vestibular nuclei, it modulates the transmission of neural signals related to motion and orientation, thereby reducing the magnitude of sensory input.


Influencing D2 Receptor Signaling in the Chemoreceptor Trigger Zone

This key action involves the Dopamine D2 receptor antagonism primarily provided by Domperidone, targeted at the Chemoreceptor Trigger Zone (CTZ) located outside the blood-brain barrier. This mechanism modulates the signal transmission within the central reflex arc that coordinates the physiological process of emesis upon detection of chemical or systemic triggers.


‍️ Modulation of Upper Gastrointestinal Motility

This peripheral mechanism is driven by Domperidone's antagonism of D2 receptors in the smooth muscle of the stomach and upper intestine. This action increases the local release of acetylcholine, which, in turn, enhances the force and coordination of peristalsis and influences the rate of transit of gastric contents.

Dosage and Administration Information

How to Use Stugil

The general principles for using the Cinnarizine and Domperidone fixed-dose combination (FDC) outline how the medicine is taken, when it is taken, and for how long. The product is administered via the oral route only, as a fixed-dose tablet.


Dosing and Administration

The standard pattern for adults and adolescents (≥ 12 years and ≥ 35 kg) involves taking one tablet, typically with strengths of Cinnarizine 20 mg and Domperidone 15 mg, up to three times per day. To achieve optimal administration conditions, the tablet is generally taken 15 to 30 minutes before meals on an empty stomach, which facilitates the absorption of the Domperidone component. Doses are typically separated by an approximate 8-hour interval. The tablet is intended to be swallowed whole with water and must not be crushed or chewed.


Duration and Specific Constraints

The use of this combination is subject to a strict duration constraint: treatment should not usually exceed seven days (one week). This limited period defines the product as being for acute, short-term administration. If a dose is missed, the standard procedure is skipping the dose and resuming the regular schedule; a compensatory double dose must not be taken. Usage criteria also dictate that the medicine is not authorized for children under 12 years of age or those weighing less than 35 kg.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Stugil

Evidence for use in Vertigo and Vestibular Disorders

This section will summarize the clinical trials and research studies evaluating patterns of symptom change associated with the study of Stugil in conditions characterized by the spinning sensation and balance issues associated with vertigo and inner ear (vestibular) disorders, including Ménière's disease.

Studies have been conducted to observe patterns of symptom change in patients experiencing various forms of vertigo. Research has explored outcomes related to physical discomfort and outcomes reflecting daily functioning or activity level. Findings from controlled studies have described patterns observed in the studies related to the intensity and frequency of vertigo symptoms. Research has explored scenarios where the combination was studied alongside its individual components or other treatments. The evidence quality varies across studies, and research does not determine whether an individual will respond similarly.


Evidence for use in Motion Sickness and Associated Nausea/Vomiting

This section will outline research exploring the investigation of Stugil in subjects with motion sickness and associated nausea and vomiting. Stugil has been studied for its use in conditions associated with acute or disruptive episodes that can occur during travel. The research so far describes patterns related to outcomes reflecting daily functioning linked to motion sickness. What remains uncertain is the full extent of observed changes in a broad range of motion sickness severity, and how its observed patterns relate to those of other agents that have been studied for this indication.


Long-term Studies and Follow-up

Most of the clinical research on Stugil has focused on its effects over defined short-term time intervals. Long-term effects are not fully established, and there is limited information for outcomes beyond these initial periods.


Evidence in Special Populations

Studies in Older Adults and Children

In the case of older adults, research exploring the use of Stugil in this group is sometimes limited. Due to natural physiological changes with age, the way the body processes the compounds may be different, and this requires special attention in research. For the pediatric population, specific clinical trial data for children remain insufficient.

Studies in Patients with Coexisting Health Conditions

Individuals with other health issues can be excluded from initial trials or constitute small subgroups. Therefore, while Stugil was observed in patients with conditions marked by functional limitations, subgroup findings are uncertain.


What is Still Uncertain About Stugil

The factors that predict observed changes in symptoms for an individual patient are not yet clearly understood. The findings were mixed in some earlier studies before the fixed-dose combination was introduced, and data are still emerging which means that certainty remains low in some aspects of research. Long-term effects are not fully established, and research is ongoing.

Frequently Asked Questions (FAQ)

Common questions about Stugil (FAQ)

Q: How is Stugil different from a common over-the-counter medicine used for similar symptoms?

Stugil is described in official documents as a Fixed-Dose Combination (FDC) drug with a unique dual mechanism. The combination is designed to stabilize the inner ear's balance signals (Cinnarizine) while also controlling the physical vomiting reflex (Domperidone). This combined approach is intended to provide comprehensive support that is distinct from medicines containing only a single agent.

Q: Does Stugil interact with hormonal birth control pills?

Official product information indicates that the Domperidone component can affect hormone levels by increasing prolactin.
