Overview of Apriso

What is Apriso?

Apriso is an extended-release capsule containing mesalamine, a compound belonging to the aminosalicylate family of medications. It is specifically formulated to deliver the active ingredient to the colon, where it works locally to manage certain inflammatory conditions.

Mechanism of Action

Mesalamine, the active component in Apriso, is thought to work by inhibiting the production of substances that cause inflammation in the lining of the colon. By reducing this inflammation, the medication helps to control symptoms and prevent the recurrence of inflammatory episodes. The extended-release delivery system is designed to ensure that the medication is released at a consistent rate as it passes through the digestive tract, targeting the affected areas effectively.

Primary Use

Apriso is primarily used for the maintenance of remission in adults with ulcerative colitis. Remission refers to periods where the symptoms of the disease, such as abdominal pain and frequent bowel movements, are significantly reduced or absent. The goal of using this medication is to extend these symptom-free periods and maintain the overall health of the intestinal lining.

What side effects are possible with Apriso?

Possible Side Effects and Safety Information

The safety profile of Apriso (mesalamine) is based on adverse reaction data collected from controlled clinical trials and post-marketing surveillance, as documented in official regulatory sources.

Common Adverse Reactions

The following side effects were reported in clinical trials with an incidence of 3% or greater:

  • Headache
  • Flatulence
  • Abdominal pain
  • Diarrhea
  • Abnormal liver function tests

Other reactions reported with an incidence less than 3% include various gastrointestinal, nervous system (e.g., tinnitus, vertigo), and skin disorders.

Serious and Clinically Significant Safety Issues

Certain severe adverse reactions have been reported with mesalamine products, requiring immediate medical attention. These include:

  • Renal Impairment: Cases of kidney function decline, including acute interstitial nephritis and renal failure, have been documented. Renal function must be evaluated before and periodically during treatment.
  • Mesalamine-Induced Acute Intolerance Syndrome: This syndrome can present with symptoms resembling an ulcerative colitis flare, such as cramping, acute abdominal pain, and bloody diarrhea.
  • Hypersensitivity Reactions: Serious reactions, including myocarditis and pericarditis (inflammation of the heart lining), have been reported.
  • Severe Cutaneous Adverse Reactions (SCARs): Rare but severe skin reactions, such as Stevens-Johnson Syndrome (SJS), have been observed.

Safety Restrictions and Monitoring

Apriso is contraindicated in patients with known hypersensitivity to salicylates, aminosalicylates, or any component of the product. Due to the risk of nephrolithiasis (kidney stones), adequate fluid intake is necessary. Specific monitoring requirements include the periodic assessment of blood cell counts and kidney function, especially in older adults and patients with pre-existing kidney or liver impairment.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory profile for mesalamine (the active ingredient in Apriso) details the manifestations and required emergency actions for an overdose. Suspected overdose often presents with signs consistent with high systemic salicylate exposure, including headache, confusion, vertigo, tinnitus (ringing in the ears), vomiting, and diarrhea.

The most severe documented outcomes involve critical organ systems. The regulatory labeling highlights the potential for renal impairment, specifically acute interstitial nephritis and renal failure, along with cases of hepatic failure. Furthermore, internal organ involvement, such as myocarditis or pericarditis related to hypersensitivity, requires immediate evaluation. Patients with pre-existing renal or hepatic impairment are noted to be at a higher risk for these severe outcomes.

If an overdose is suspected, or if signs of severe toxicity (like the Acute Intolerance Syndrome) appear, immediate medical attention must be sought. Official documentation explicitly states that there is no specific antidote available. Treatment is restricted to symptomatic and supportive measures, including the correction of fluid and electrolyte imbalances and close monitoring of renal function. Prompt discontinuation of the medication is also mandated if signs of acute intolerance are observed.

Therapeutic Uses of Apriso

Quick Facts

  • Apriso is for use in adults to maintain a state without active symptoms of ulcerative colitis.
  • Apriso assists in the management of ulcerative colitis by supporting the continuation of remission.

What Apriso Treats: Main Uses and Benefits

Apriso (mesalamine) is a medication utilized for the long-term management of ulcerative colitis in adults. Its primary therapeutic purpose is to sustain the period of disease remission.

Ulcerative colitis is a chronic condition that causes inflammation in the large intestine. When the condition is in remission, the individual experiences a period with minimal to no active symptoms. Apriso is an option available to eligible adult patients to help preserve this state of remission, thereby assisting in the avoidance of symptom recurrence or a flare-up of the condition.

This medication is a specific formulation of mesalamine indicated solely for the maintenance phase of this condition in adults. It is not indicated for the initial treatment of active ulcerative colitis.

Eligibility and Restrictions for Use

The eligibility profile for Apriso (mesalamine) is strictly defined by regulatory documentation, establishing who is officially allowed to use the medicine and who must be excluded.

Apriso is contraindicated and must not be used by any patient with a known or suspected hypersensitivity to salicylates (such as aspirin) or to other aminosalicylates (like mesalamine).

Age-Related Eligibility

Apriso is indicated solely for adults aged 18 years and older for the maintenance of ulcerative colitis remission. Safety and effectiveness have not been established in pediatric patients under 18 years of age. Use in older adults (geriatric patients) is permitted but requires caution due to the greater frequency of potential decreased organ function.

Conditional Use and Restrictions

Conditional use is required for specific patient populations:

  • Renal or Hepatic Impairment: Use requires caution. Kidney and liver function must be evaluated before initiating therapy and monitored periodically during treatment.
  • Pregnancy and Lactation: Use is generally advised only if clearly needed. Caution is required during breastfeeding, and the infant should be monitored for adverse effects.

What should I know about interactions with other medicines?

Apriso (mesalamine) can interact with several other medications, which may alter the effectiveness of Apriso or increase the risk of side effects. It is important to inform your healthcare provider about all prescription drugs, over-the-counter medicines, and herbal supplements you are currently taking.

Medications to Monitor

Drug Class Potential Interaction Recommendation
Antacids May cause the Apriso coating to dissolve too soon, leading to reduced effectiveness. Do not take antacids with Apriso.
Nonsteroidal Anti-inflammatory Drugs (NSAIDs) Increased risk of kidney problems (nephrotoxicity). Examples include ibuprofen and naproxen. Use with caution; kidney function should be monitored.
Nephrotoxic Agents Drugs known to be harmful to the kidneys, such as certain antibiotics (e.g., aminoglycosides), may have an additive risk of renal adverse effects when combined with Apriso. Use with caution; kidney function should be monitored.
Azathioprine or 6-Mercaptopurine Increased risk of blood disorders due to altered metabolism of these immunosuppressants. Close monitoring of blood cell counts is necessary.
Warfarin and other Anticoagulants Mesalamine may potentiate or diminish the effects of anticoagulants, leading to an increased risk of bleeding or clotting. Close monitoring of the International Normalized Ratio (INR) is required; dosage adjustments may be needed.

Apriso contains phenylalanine (a component of aspartame), which should be considered if you have Phenylketonuria (PKU). Since this list is not exhaustive, always consult your physician for a complete review of your medication regimen.

Mechanism of Action

How Apriso Works: Mechanism of Action

Mesalamine is designed to act locally within the colon, influencing core biological systems that regulate inflammatory processes.

COX and LOX Enzyme Inhibition

This mechanism focuses on inhibiting the action of enzymes like Cyclooxygenase ( COX) and Lipoxygenase ( LOX) within the colonic mucosa. By blocking these enzymes, the drug prevents the metabolism of arachidonic acid into key pro-inflammatory mediators such as prostaglandins and leukotrienes, resulting in a reduction of the biosynthesis of pro-inflammatory chemical signals.

Modulation of Gene-Regulating Pathways

Apriso actively modulates transcription factors, specifically acting as an agonist of PPARgamma and an inhibitor of NF-kappa B activation. This action modulates the transcriptional regulation of inflammatory mediators, influencing the activity state within targeted pathways.

Antioxidant and Mucosal Protection

The drug engages mechanisms that scavenge free radicals (Reactive Oxygen Species or ROS) that are generated during inflammatory processes. This antioxidant activity helps to limit direct cellular damage and oxidative stress, which influences the maintenance of the epithelial barrier structure and limits the cellular impact of overactive physiological signaling.

Dosage and Administration Information

Apriso is an extended-release capsule taken by mouth, with specific instructions for administration to ensure proper function of the medicine's coating.

Official Administration Guidelines

Guideline Instruction
Recommended Dose (Adults) 1.5 g (four 0.375 g extended-release capsules)
Frequency and Timing Once daily, to be taken in the morning
Food Relationship May be taken with or without food
Method Swallow the capsules whole; do not cut, break, crush, or chew
Antacid Restriction Do not co-administer with antacids, as this may interfere with the capsule's release mechanism
Fluid Intake Patients should drink an adequate amount of fluids during treatment

Population and Procedural Rules

  • Adult Use Only: The medicine is approved for use in adults (18 years of age and older). Safety and efficacy have not been established in pediatric patients.
  • Renal Function: An evaluation of kidney function is recommended before starting therapy and periodically while continuing treatment.
  • Phenylketonuria (PKU): The capsule contains aspartame, a source of phenylalanine (0.56 mg per capsule), which patients with PKU must consider in their total daily intake.

Following these precise procedural steps, which strictly govern the dose, timing, and method of ingestion, is required to ensure the correct release of the extended-release medication.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Apriso

Evidence for use in Maintaining Ulcerative Colitis Remission

Research for Apriso has mainly focused on its intended use in adults, examining the maintenance phase of ulcerative colitis (UC), which is a condition characterized by fluctuating or episodic manifestations. The primary evidence base comes from two large, short-term randomized, double-blind, placebo-controlled clinical trials.

The studies focused on outcomes related to physical discomfort and outcomes reflecting daily functioning or activity level. Researchers primarily measured relapse-free status in patients who were already in remission. The findings from a combined analysis of the two main trials describe patterns observed in the studies over a six-month follow-up period. The data indicate patterns related to sustaining a relapse-free state among the study participants during this defined time interval.

Comparing Apriso Research to Placebo

The controlled studies were specifically structured to evaluate Apriso against an inactive substance (placebo). This approach is relevant in trials assessing short-term symptom patterns, and provides a baseline against which any observed changes in the study groups were compared in the research. These trials explored short-term symptom changes, with researchers monitoring outcomes reflecting daily functioning and the need for new treatment due to worsening symptoms.

Long-Term Studies and Follow-Up Data

While the main randomized, controlled trials were conducted for a limited duration of six months, researchers have also explored longer-term patterns. Some participants continued in an open-label, uncontrolled study to observe responses over a defined time interval that extended up to 24 months. The studies monitored outcomes related to the maintenance of remission in an uncontrolled setting; the certainty remains low compared to the six-month controlled data because there was no placebo group for comparison during this extended period.

Evidence in Special Populations

  • Older Adults (Age 65 and over): The original clinical studies did not include sufficient numbers of subjects aged 65 and over. Data for this group remain insufficient, and the results apply only to the younger adult populations studied.
  • Children and Adolescents: Apriso was studied for maintenance of remission in adults only. The safety and observed effectiveness of the drug was not evaluated in or established through studies conducted in pediatric patients.
  • Pregnancy-Related Populations: Research has explored the use of the active ingredient (mesalamine) during pregnancy; however, there are currently no adequate and well-controlled studies specifically on Apriso in pregnant women.

What is Still Uncertain About Apriso Research

A primary limitation is that follow-up durations were limited in the most rigorous, placebo-controlled trials. This means that controlled data for use beyond six months is lacking. Comparative evidence with other specific mesalamine formulations is also an area where data are still emerging. Subgroup findings are uncertain due to the modest sample sizes of older adults included in the pivotal studies.
