Overview of Coloverin SR

Quick Facts

Feature Detail
Active Ingredient Mebeverine Hydrochloride
Drug Class Antispasmodic Agent
Primary Use Symptoms of Irritable Bowel Syndrome (IBS)
Formulation SR (Sustained/Slow Release) Capsule

Coloverin SR is a brand name for a medication whose active pharmaceutical ingredient is mebeverine hydrochloride. It belongs to a class of drugs known as antispasmodics or musculotropic agents.

Primary Indication and Function

This medication is primarily used for the symptomatic treatment of Irritable Bowel Syndrome (IBS) and other functional bowel disorders. IBS is a common condition that involves spasms and pain in the intestines, often leading to symptoms like abdominal cramps, discomfort, persistent diarrhea, and/or alternating constipation.

Mebeverine works directly on the smooth muscles of the gastrointestinal (GI) tract to relieve painful spasms and abnormal contractions without significantly affecting the normal movements (motility) of the gut. Its exact mechanism is complex and not fully understood, but it is thought to involve multiple pathways, including affecting ion channels in the muscle cells to cause relaxation.

SR Formulation

Coloverin SR is formulated as a slow-release or modified-release capsule, which is designed to gradually release the mebeverine over an extended period. This provides a sustained therapeutic effect, typically allowing for a less frequent dosing schedule compared to immediate-release forms.

What side effects are possible with Coloverin SR?

Therapeutic Uses of Coloverin SR

What Coloverin SR Treats

Coloverin SR is a medication formulated to manage symptoms associated with functional gastrointestinal disorders. It belongs to a class of medicines known as antispasmodics, which work directly on the smooth muscles of the digestive tract.

Main Uses

The primary application of Coloverin SR is the symptomatic treatment of Irritable Bowel Syndrome (IBS) and similar conditions characterized by intestinal spasms. It is commonly used to address the following symptoms:

  • Abdominal Pain and Cramping: Relieving the sharp or dull pain caused by involuntary muscle contractions in the gut.
  • Bloating and Distension: Reducing the feeling of fullness and visible swelling in the abdominal area.
  • Altered Bowel Habits: Assisting in the management of diarrhea or constipation when these are linked to intestinal spasms.
  • Flatulence: Helping to alleviate discomfort caused by excess gas trapped in the digestive system.

Benefits and Mechanism

Coloverin SR utilizes a sustained-release (SR) mechanism, which allows the active ingredient to be released gradually into the system. This provides several clinical benefits:

  • Targeted Action: The medication acts specifically on the muscle wall of the intestine to induce relaxation without affecting normal bowel movement or interfering with the autonomic nervous system.
  • Extended Symptom Control: Due to its slow-release formulation, the medication provides a prolonged effect, helping to maintain comfort over a longer period compared to immediate-release versions.
  • Reduction of Spasms: By preventing the hyper-reactivity of the intestinal muscles, it helps restore the natural rhythm of the digestive tract, leading to a reduction in the frequency and intensity of abdominal discomfort.

Eligibility and Restrictions for Use

Who Can and Cannot Use Coloverin SR?

Regulatory authorities define the specific populations eligible for Coloverin SR (mebeverine hydrochloride) based on established safety and efficacy data. This medicine is primarily intended for use in adults aged 18 years and older.


Eligibility Restrictions

Category Regulatory Status
Age Restriction Not recommended for children and adolescents below 18 years due to insufficient data.
Pregnancy Not recommended for use during pregnancy.
Breastfeeding Should not be used by breastfeeding women.
Contraindications Contraindicated in patients with known hypersensitivity (allergy) to the drug or its excipients.
Metabolic Disorders Contraindicated in individuals with rare hereditary problems, such as galactose intolerance or glucose-galactose malabsorption.
Organ Function Use with caution is advised for patients with advanced renal or hepatic impairment, as noted in some regulatory documents.

These constraints define the official eligibility profile and ensure the medicine is used only in populations where its use is documented as acceptable or established by governing health agencies.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The official interaction profile for Coloverin SR (mebeverine hydrochloride) is defined by the findings from regulatory-mandated studies and the absence of data for many common interaction types. The overall structure is characterized by a lack of formally documented restrictions concerning other medications.

Interaction Type Official Regulatory Statement
Drug–Drug Interactions No formal interaction studies have been performed with other medicinal products.
Metabolic Interactions No specific metabolic (CYP enzyme) or drug transporter-mediated interactions are documented in regulatory labeling.
Contraindicated Combinations The official prescribing information does not list any medicinal products that are formally prohibited for co-administration due to interaction risk.

The lack of documented studies means the regulatory profile contains no established rules for pharmacokinetic alterations or pharmacodynamic effects involving co-administered medicines. Consequently, there are no mandatory requirements for dose timing separation stated in the official prescribing information.

The single substance for which a formal interaction study result is documented is ethanol (alcohol). Regulatory authorities explicitly confirm the absence of any interaction between mebeverine hydrochloride and alcohol, based on findings from in vitro and in vivo studies. This finding forms the primary explicit piece of information available concerning external substance interactions. The interaction structure for Coloverin SR is thus focused on a general lack of available regulatory data concerning co-administered substances.

Mechanism of Action

Direct Musculotropic Action and Ion Channel Modulation

Mebeverine primarily works by directly influencing the smooth muscle cells of the gastrointestinal (GI) tract. Its core mechanism involves modulating Voltage-operated Calcium ( Ca^2+) and Sodium ( Na^+) channels, which are essential regulators of muscle cell excitability and contraction. By interfering with the excessive influx of these ions across the cell membrane, the drug causes spasmolysis, resulting in the reduction of elevated smooth muscle tone and the modulation of GI smooth muscle contractile patterns.

Mechanistic Specificity and Sustained Effect Profile

The mechanism is characterized by its high degree of local specificity, exhibiting low affinity for non-target receptors, such as systemic muscarinic receptors. Furthermore, the Sustained-Release (SR) formulation is a mechanical feature that facilitates the pharmacological mechanism by continuously providing the drug to the muscle fibers. This prolonged and localized concentration allows for sustained modulation of muscle excitability to be maintained over an extended period.

Dosage and Administration Information

How to Use Coloverin SR

Coloverin SR (mebeverine hydrochloride) is a medication formulated for oral use only as a 200 mg modified-release capsule. The general principles for administration focus on ensuring the sustained-release mechanism is maintained and aligning the timing with meals.


Standard Administration Guidelines

Feature Official Use Principle
Route & Form Oral; 200 mg modified-release capsule.
Adult Dosing One capsule (200 mg) per dose.
Frequency Twice daily (B.I.D.), typically morning and evening.
Intake Condition Taken approximately 20 minutes before a meal.

Procedural Instructions

The modified-release capsule must be swallowed whole with a sufficient amount of water (e.g., 100 ml); it must not be chewed or crushed. This specific instruction is necessary to preserve the intended slow release of the active ingredient.

Duration and Special Populations

Treatment duration is not limited and may continue as needed for symptomatic relief. Guidance suggests that the dose may be gradually reduced once symptoms have been controlled for several weeks. No dosage adjustment is generally required for older adults or patients with kidney or liver impairment. However, use is not recommended for children and adolescents under 18 years of age due to insufficient safety and efficacy data.

In the event of a missed dose, the patient should not take a double dose to compensate; the regular dosing schedule should simply be resumed with the next planned dose.

Recent Clinical Evidence

Coloverin SR: Recent Clinical Evidence


Evidence for Symptomatic Management of Irritable Bowel Syndrome (IBS)

This section summarizes the core clinical evidence base for Coloverin SR, describing the types of Randomized Controlled Trials (RCTs), Systematic Reviews, and Meta-analyses that research examined in studies examining outcomes related to the primary symptoms of IBS. Coloverin SR was studied for conditions characterized by fluctuating or episodic manifestations, such as Irritable Bowel Syndrome and related functional bowel disorders. Short-term RCTs, which compare the drug to an inactive placebo, were studied in adult populations diagnosed with IBS. Findings describe patterns observed in the studies regarding the proportion of participants reporting improvement in global symptoms and abdominal pain, which is the key area used in research exploring patient-reported outcomes.

Outcomes Studied in Clinical Trials

The trials used in research exploring how symptoms change over time focused heavily on outcomes related to physical discomfort, primarily abdominal pain and cramping. Studies explored how symptoms evolved in the observed populations, with endpoints including a patient’s global assessment of relief and the severity of outcomes related to systemic or functional imbalance, such as abdominal distension and bloating. Research also examined outcomes related to abnormal bowel habits, including stool frequency and consistency.


Comparison of Findings to Placebo and Other Treatments

This part outlines the structure of comparative studies that have been conducted, including how data were gathered where Coloverin SR was studied alongside other treatments and when it was evaluated in comparisons to other available antispasmodic agents. Reviews indicate that for the primary outcome of global symptom improvement, concerns related to consistency were reported when compared with placebo in some large-scale scientific reviews.


Long-Term Studies and Follow-up Duration

The follow-up durations for many randomized trials were limited, ranging typically from four to sixteen weeks. There is limited information for long-term outcomes that persist beyond six months, and long-term effects are not fully established regarding the durability of findings.


Scientific Uncertainty and Research Gaps

This concluding section synthesizes the main limitations documented in regulatory and peer-reviewed summaries, clarifying the areas where findings were mixed, where research is still developing, and where data remain insufficient. Certainty remains low concerning the overall consistency of results when data from all short-term RCTs were evaluated in meta-analyses. Furthermore, subgroup findings are uncertain regarding how different IBS subtypes may have been explored across the entire research landscape.
