What is Mesalazine, the Active Component in Salofalk GR?

Salofalk GR is a specific brand of a pharmaceutical preparation containing the active ingredient Mesalazine. Mesalazine is an essential intestinal anti-inflammatory agent, chemically classified as 5-aminosalicylic acid (5-ASA), and belongs to the aminosalicylates class of drugs. It is a synthetic chemical entity, derived from the structural family of salicylates, and is produced by Dr. Falk Pharma GmbH. Mesalamine is utilized for its effectiveness in reducing bowel inflammation. This anti-inflammatory capability is clinically recognized for its effectiveness in localized therapy. Unlike related medications such as sulfasalazine, which requires bacterial conversion, this single-component brand delivers the 5-ASA directly.

The Role of the Modified Release Granule Form

Salofalk GR is differentiated by its unique presentation as modified release granules packaged in individual sachets, intended for oral route administration. The "GR" designation highlights this specialized multi-particulate formulation. The granules feature a sophisticated design, including a specialized gastro-resistant coating and a matrix granule structure. This formulation ensures a reliable, pH-dependent release of the drug in the lower intestinal regions. This targeted delivery system offers a versatile alternative for maximizing the concentration of the active ingredient at the site of inflammation within the colon.

General Purpose: Anti-inflammatory Action in the Intestine

The general purpose of Salofalk GR is to exert a local anti-inflammatory effect directly on the inflamed lining of the bowel. By acting topically on the tissue, the Mesalazine helps interrupt the chemical cascade of inflammation, including acting as a radical scavenger and modulating local chemical signals. This topical action mechanism allows the drug to soothe and help heal irritated intestinal tissue, assisting in the control and maintenance of a reduced state of inflammation over time with minimal systemic bioavailability.

What side effects are possible with Salofalk GR?

Possible Side Effects and Safety Information

The safety profile for Mesalazine (Salofalk GR) is officially classified based on the frequency and system-organ classes of documented adverse reactions, as defined in regulatory documents like the Summary of Product Characteristics (SmPC) and FDA Prescribing Information.


Frequency-Classified Adverse Reactions

Side effects are categorized based on their reported incidence:

Classification Examples of Documented Adverse Reactions
Common (1% to 10%) Headache, dizziness, abdominal pain, diarrhea, nausea, vomiting, flatulence, rash, and pruritus.
Rare (< 1/1,000) Myocarditis, pericarditis (hypersensitivity reactions), pancreatitis, and peripheral neuropathy.
Very Rare (< 1/10,000) Acute kidney failure, chronic interstitial nephritis, severe blood disorders (e.g., agranulocytosis, aplastic anemia), and severe cutaneous adverse reactions (SCARs) such as Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN).

System-Organ Classes and Safety Constraints

Adverse effects are documented across various systems, including Gastrointestinal Disorders, Nervous System Disorders, Cardiac Disorders, Renal and Urinary Disorders, and Blood and Lymphatic System Disorders. The labeling notes that an acute intolerance syndrome may occur, characterized by fever, cramping, and bloody diarrhea, which may be difficult to distinguish from an exacerbation of the underlying disease.

The medication is officially contraindicated in individuals with a known hypersensitivity to Mesalazine or salicylates, and in those with severe renal or severe hepatic impairment. Caution is also advised in patients with a history of hypersensitivity to sulfasalazine due to the potential for cross-sensitivity.

Overdose and Emergency Response

Overdose Manifestations and When to Seek Help

Regulatory information on mesalazine overdose, the active ingredient in Salofalk GR, is primarily drawn from documented cases of acute, high oral doses. Due to its pharmacological classification as an aminosalicylate, an overdose may present with specific signs and symptoms resembling established salicylate toxicity.

Official Manifestations System Documented Signs/Symptoms
Gastrointestinal Nausea, Vomiting, Abdominal pain
Neurologic/Other Headache, Confusion, Dizziness, Tinnitus (ringing in the ears)
Respiratory Tachypnea (rapid, shallow breathing), Hyperpnea (deep, labored breathing)

Severe Outcomes and Required Action Severe intoxication carries the risk of significant systemic effects, specifically electrolyte and blood pH imbalance. The most severe outcomes cited in regulatory contexts involve potential damage to the renal and liver organs. Immediate emergency action is required for any suspected overdose. Official labeling mandates contacting a regional poison control centre for guidance and seeking symptomatic treatment at a hospital.

Management and Monitoring Regulatory documents state that no specific antidote is known for mesalazine overdose. Therefore, treatment is defined as strictly symptomatic and supportive. This official management protocol requires close monitoring of renal function and the correction of fluid and electrolyte imbalances while the patient is under hospital observation.

Therapeutic Uses of Salofalk GR

Salofalk GR is a medication used to address inflammatory conditions primarily affecting the bowel. Its main applications include the treatment of acute episodes of mild-to-moderate ulcerative colitis, which is a long-term condition that causes inflammation in the colon and rectum.


Quick Facts

  • Goal: To help manage inflammation and contribute to symptom relief.
  • Primary Application: Treatment of acute episodes of mild-to-moderate ulcerative colitis.
  • Long-Term Purpose: Used for the maintenance of remission in ulcerative colitis to assist in preventing recurrence of symptoms.

The medication also serves as an option for the maintenance of remission in ulcerative colitis, a phase focused on helping to prevent recurrence of active inflammation and symptoms over time. It is intended to address the underlying inflammation associated with the condition.

Salofalk GR may be indicated for specific cases of Crohn's ileitis and colitis, which are related forms of inflammatory bowel disease, as part of a therapeutic plan to contribute to favorable outcomes. The active component, mesalazine, has an established therapeutic profile for these conditions.

Eligibility and Restrictions for Use

Who Can and Cannot Use Salofalk GR?

The eligibility for Salofalk GR (mesalazine granules) is strictly defined by regulatory criteria concerning the patient’s clinical status and age, as documented in official prescribing information.

Eligibility Status Patient Population / Condition
Contraindicated (Must Not Use) Hypersensitivity to salicylates, mesalazine, or any product excipients. Severe impairment of hepatic or renal function.
Use Not Recommended Children below the age of 6 years due to very limited experience and insufficient documentation.

Conditional Use Requirements

The medicine is generally permitted for use in adults and older adults, provided they do not have severe organ impairment. However, mild to moderate impairment of renal or hepatic function requires the medicine to be used with caution and necessitates close monitoring. Conditional use is also required for patients with chronic lung impairment, such as asthma, or a history of allergy to sulfasalazine. Use during pregnancy and breastfeeding is restricted and should only proceed if the potential clinical benefit outweighs the possible risks to the child. For children and adolescents aged 6 to 18 years, documentation for the medicine’s efficacy is limited.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documents define the interaction profile of Salofalk GR (Mesalazine) primarily through risks of additive toxicity and pharmacodynamic modifications with certain co-administered substances.

Documented Pharmacodynamic and Toxicity Interactions

Interacting Substance/Class Official Regulatory Description
Azathioprine, 6-Mercaptopurine, Thioguanine Possible increase in the myelosuppressive effects; associated with increased 6-thioguanine nucleotide (6-TGN) concentrations [Exposure Modification].
Nephrotoxic Agents (e.g., NSAIDs) Increased risk of nephrotoxicity and renal adverse reactions.
Coumarin-type Anticoagulants (e.g., Warfarin) Possible potentiation of the anticoagulant effect, or weak evidence of a decrease in the anticoagulant effect.
Lactulose or similar preparations May cause a reduction of mesalazine release from the modified-release granules.

Other Documented Interactions

Co-administration with Glucocorticoids may increase undesirable gastric effects, and interactions with Sulfonylureas may increase their blood glucose-lowering effects. The drug or its metabolite, N-Ac-5-ASA, is also officially documented to interfere with certain laboratory procedures, causing spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography. No medicinal products are explicitly designated as contraindicated combinations in the regulatory labels, and no mandatory timing separation rules are documented.

Mechanism of Action

Salofalk GR (mesalazine) acts locally on the cells lining the large intestine, where it engages mechanisms that modulate the inflammatory response. The mechanism involves several distinct actions at the molecular and cellular level.

Modulating Inflammatory Mediators

The medication acts by inhibiting key enzyme systems, including cyclooxygenase (COX) and lipoxygenase (LOX), within mucosal cells. This interaction blocks the enzymatic conversion of precursor molecules into pro-inflammatory lipid mediators such as prostaglandins and leukotrienes. This process limits the initial biochemical signaling associated with the generation of these mediators.

Regulating Genetic Signaling Pathways

Mesalazine influences core cellular control systems by interfering with transcription factors, notably NF-kB (Nuclear Factor-kappa B). NF-kB is a regulatory protein complex that, when active, modulates the gene expression of numerous inflammatory proteins (cytokines). By inhibiting this factor, the drug reduces the transcription of inflammatory proteins, which modulates the mobilization and activity of immune cells.

Scavenging Reactive Oxygen Species

The compound exhibits antioxidant properties, enabling it to directly neutralize highly reactive molecules known as free radicals or Reactive Oxygen Species (ROS). These highly reactive species are byproducts of immune cell activity and contribute to local biochemical changes. This activity limits the chemical stress on mucosal cells, thereby influencing the consequences of oxidative stress on tissue biology.

Dosage and Administration Information

Salofalk GR (mesalazine modified-release granules) should be taken exactly as prescribed by your doctor. The dosage and duration of treatment are determined by your individual condition (acute episode or maintenance of remission) and its severity. Consistency is essential for therapeutic success.

Administration Instructions

  • Do not chew or crush the contents of the sachet, as this will compromise the modified-release coating and may alter the medication's effectiveness.
  • Tear open the sachet and pour the entire contents onto your tongue.
  • Swallow the granules whole immediately, followed by plenty of fluid, such as a glass or two of water, to wash the medicine down.
  • Take your dose(s) at the same time each day to help maintain regularity and ensure consistent drug levels.

Dosing Guidelines for Adults

Your doctor will determine the precise dose. General recommendations are as follows:

Indication Recommended Daily Dosage (Mesalazine)
Acute Ulcerative Colitis 1.5 g to 3 g daily, preferably once a day in the morning or in 2-3 divided doses.
Maintenance of Remission 1.5 g daily, preferably once a day.

Treatment for an acute episode of ulcerative colitis typically lasts up to 8 weeks, but the duration is always determined by your physician. Do not discontinue use without consulting your doctor, even if your symptoms improve.

Recent Clinical Evidence

Research Evidence: Overview of Studies for Salofalk GR

Evidence for Use in Inducing Remission in Ulcerative Colitis

Research exploring the use of Salofalk GR was studied for adults with active Ulcerative Colitis in trials assessing short-term or episodic symptom patterns. The primary research conducted includes randomized, double-blind, multicenter trials, which represent a common study design for evaluating medications. These studies examined specific outcomes related to physical discomfort and inflammatory states, specifically in populations diagnosed with mild-to-moderate active Ulcerative Colitis.

Studies monitored participants over defined, short-term intervals (often around eight weeks). The research examined changes measured during the study period, such as the evolution of symptoms and the healing of the colon lining (Endoscopic Remission), reflecting the absence or reduction of inflammation. Findings describe patterns regarding the proportion of individuals whose status met the criteria for clinical remission at the end of the short study duration. Results apply only to the populations studied; this research provides limited insight into long-term disease progression or the outcomes for individuals whose condition is more severe.


Evidence for Use in Maintaining Remission in Ulcerative Colitis

Research has also explored the use of this medication in studies examining conditions characterized by fluctuating manifestations, focusing on outcomes related to avoiding periods of heightened symptoms. The evidence is derived from placebo-controlled trials designed to track participants who had already achieved a stable state of remission. These maintenance studies observe responses over defined time intervals, typically six months to one year.

Studies explored whether continuous use was observed in trials evaluating a lack of heightened symptom activity. Data show patterns related to the observed duration of stable status in participants during the study. Evidence remains limited regarding certain groups, and comparative evidence is lacking in large-scale trials that directly compare the long-term observed stable status of this specific granule formulation against all other mesalazine formulations.


What Remains Uncertain in the Research Landscape

While research describes the patterns observed so far, certain limitations in the data for certain groups remain insufficient. For instance, few studies are specifically designed to examine long-term effects beyond a year or two for every individual. Long-term effects are not fully established for all potential scenarios. Comparative evidence is lacking in high-quality trials that directly assess the long-term study outcomes of Salofalk GR against all other treatment options for UC maintenance.

Frequently Asked Questions (FAQ)

Common questions about Salofalk GR (FAQ)


Q: What happens if I take my Salofalk dose later than usual?

A: If you realize you have missed a dose of Salofalk GR, official product information generally recommends that a missed dose should be skipped completely. You would then take your next dose at the normal time it is due. It is not generally advised to take a double dose to compensate for the one that was missed.


Q: What is the recommended daily dosage for children aged 6 to 18?

A: According to official regulatory documents, the exact dosage for children aged 6 and older is individually determined by a physician based on the child's body weight. Regulatory guidelines suggest that children over 40 kg body weight may be prescribed the adult dosage. The physician specifies the precise amount needed to either manage an active flare or maintain remission.


Q: Can I store the medicine in my bathroom cabinet?

A: Regulatory documents indicate the medicine must be stored in its original sachet packaging and kept in a location where the temperature remains below 25 C and is protected from light. Because bathrooms are often humid and experience frequent temperature fluctuations, they may not consistently meet these cool and dry storage requirements.


Q: Is Salofalk GR gluten-free or lactose-free?

A: Salofalk formulations are often officially documented as gluten-free. While regulatory documents list all inactive ingredients, they generally do not contain lactose.
