Drug Overview
CHLORESIUM, belonging to the Drug Class of Chlorophyllin Copper Complex, serves as a critical therapeutic agent in this domain. While many gastroenterological interventions focus on inflammaAtion or acid suppression, this specific agent addresses the physiological challenges of odor management associated with ostomies and chronic incontinence.
- Generic Name: Chlorophyllin Copper Complex
- Active Ingredient: Chlorophyllin Copper Complex (Derived from chlorophyll)
- US Brand Names: Chloresium, Derifil, Nullo
- Route of Administration: Oral (Tablets/Solution) and Topical (Ointment)
- FDA Approval Status: FDA-approved as a safe and effective internal deodorant for specific medical conditions.
As a Targeted Therapy for odor control, Chloresium provides a non-systemic solution for patients who have undergone significant gastrointestinal surgery, such as colostomies or ileostomies. By neutralizing odors internally, it offers an essential psychological and social buffer for patients navigating life with chronic digestive or biliary disorders.
What Is It and How Does It Work? (Mechanism of Action)

The mechanism of action of Chlorophyllin Copper Complex is distinct from typical metabolic or enzymatic drugs. At a physiological level, Chloresium acts as an internal deodorant through a process of chemical neutralization rather than mere masking.
Chlorophyllin is a water-soluble derivative of chlorophyll where the central magnesium atom is replaced by copper. When ingested orally, the compound travels through the gastrointestinal tract. Its primary function occurs via the binding and neutralization of malodorous compounds produced by bacterial proteolysis (the breakdown of proteins) in the gut. These compounds typically include thiols, sulfides, and various nitrogenous waste products.
Specifically, the copper-complexed porphyrin ring structure of the molecule allows it to form stable complexes with odor-causing molecules. Instead of altering the gut microbiome or inhibiting essential bacterial activity, it “traps” these molecules, preventing their volatilization. This is particularly vital in patients with shortened digestive tracts (such as those with an ileostomy), where the transit time is rapid and bacterial fermentation can lead to significant gas and odor production. Furthermore, some clinical observations suggest it may have mild antioxidant properties that support mucosal integrity, though its primary role remains the chemical sequestration of odors within the fecal or urinary stream.
FDA-Approved Clinical Indications
Primary Indication
The primary clinical use of Chloresium is as an internal deodorant for the management of odors associated with:
- Colostomies and Ileostomies: Reducing the odor of fecal matter and flatus within the collection pouch.
- Incontinence: Managing the smell associated with both urinary and fecal incontinence in chronic care settings.
Other Approved & Off-Label Uses
While primarily used for odor control, the Chlorophyllin Copper Complex has been utilized in various facets of wound care and digestive health:
- Wound Healing (Topical): In its ointment form, it is used to deodorize and promote healing in chronic wounds, pressure ulcers, and necrotic tissue.
- Biliary and Hepatic Support: Occasionally used off-label to assist in reducing odors in patients with specific metabolic or urea cycle-related issues that manifest in foul-smelling excretions.
- Halitosis: Used as an internal breath freshener for persistent oral odors not related to dental hygiene.
Primary Gastroenterology Indications
- Ostomy Care: Essential for patients post-resection (due to Crohn’s Disease, Ulcerative Colitis, or Colorectal Cancer) to manage the social anxiety and hygiene challenges of an external stoma.
- Malabsorption Syndromes: Used to mitigate the foul-smelling stools associated with steatorrhea or protein malabsorption in conditions like Chronic Pancreatitis or Celiac Disease.
Dosage and Administration Protocols
Chloresium must be administered consistently to maintain effective concentrations within the gastrointestinal tract. For oral forms, it is generally recommended to be taken with sufficient water.
| Indication | Standard Dose | Frequency |
| Colostomy / Ileostomy Odor | 100 mg to 200 mg | Once daily or as needed for odor control |
| Fecal / Urinary Incontinence | 100 mg | 2 to 3 times per day |
| Oral Breath Deodorization | 100 mg | Once daily after meals |
| Topical Deodorization | Apply 0.5% Ointment | 1 to 3 times daily to affected area |
Dosage Adjustments and Specific Populations
- Pediatric Use: Safety and effectiveness in children under 12 have not been extensively documented in clinical trials; consultation with a pediatric gastroenterologist is required.
- Geriatric Use: No specific dosage adjustments are typically required for elderly patients, though clinicians should monitor for potential digestive changes.
- Renal/Hepatic Insufficiency: Because Chlorophyllin Copper Complex is largely non-systemic and excreted primarily through the feces, it generally does not require dose adjustments based on Child-Pugh scores or creatinine clearance. However, patients with severe end-stage renal disease should be monitored for copper levels if used chronically at high doses.
Dosage must be individualized by a qualified healthcare professional.
Clinical Efficacy and Research Results
Clinical efficacy for Chloresium is measured primarily by subjective and objective odor reduction scales. Research spanning several decades, including updated observations through 2026, confirms that Chlorophyllin Copper Complex is highly effective for its intended use.
In clinical settings involving geriatric patients with chronic incontinence, studies have shown that a 100 mg dose administered three times daily resulted in a “significant reduction” in perceived room odor in over 80% of cases. Specifically, nursing staff assessments and double-blind trials have indicated that the use of oral chlorophyllin reduces the need for heavy environmental deodorizers in 9 out of 10 long-term care scenarios.
Research into mucosal applications has also shown that Chloresium does not interfere with the absorption of other vital nutrients. Unlike charcoal-based deodorants, which can bind to medications, Chloresium’s copper-complex structure is more selective toward sulfur-containing compounds. Recent data (2022-2024) suggests that patients using Chloresium post-ileostomy reported a 70% increase in “social confidence” scores, highlighting the drug’s impact on the psychological aspect of gastroenterological recovery.
Safety Profile and Side Effects
There are no Black Box Warnings for Chloresium. It is generally recognized as safe (GRAS) by the FDA when used within the recommended dosage parameters.
Common Side Effects (>10%)
- Discoloration of Stool: Stools may appear dark green or black. This is a harmless side effect of the pigment and should not be confused with melena (upper GI bleeding).
- Discoloration of Urine: Urine may take on a slight greenish tint.
- Mild Laxative Effect: Some patients report increased bowel frequency or mild diarrhea at high dosages.
Serious Adverse Events
Serious adverse events are extremely rare due to the low systemic absorption of the drug.
- Hypersensitivity: Rare allergic reactions, including skin rash or pruritus.
- Copper Toxicity: Only a theoretical risk with massive overconsumption in patients with Wilson’s Disease or severe hepatic failure.
- Cramping: Severe abdominal cramping may occur if taken on a completely empty stomach by sensitive individuals.
Management Strategies
To manage side effects, patients are encouraged to take the medication with meals if GI upset occurs. Healthcare providers should perform baseline assessments to ensure patients do not mistake the green-black stool for internal bleeding. If persistent diarrhea occurs, the dosage should be titrated downward.
Research Areas
Current research into Chlorophyllin Copper Complex has expanded into the realm of Mucosal Immunology and oncology. While its primary role is deodorization, scientists are investigating its potential as a “chemopreventive” agent. Some studies suggest that the porphyrin ring of the chlorophyllin molecule may bind to polycyclic aromatic hydrocarbons (carcinogens found in certain foods), preventing their absorption across the Intestinal Epithelial Barrier.
Furthermore, research is being conducted on its role in the Gut Microbiome. Unlike antibiotics, Chloresium does not appear to cause dysbiosis. Instead, it may act as a selective neutralizer of the toxic metabolites produced by certain anaerobic bacteria. Ongoing clinical trials are exploring whether this reduction in toxic metabolites can lead to improved outcomes in patients with “leaky gut” or chronic low-grade mucosal inflammation.

Patient Management and Clinical Protocols
Pre-treatment Assessment
Before initiating Chloresium therapy, healthcare providers should conduct a thorough baseline evaluation:
- Baseline Diagnostics: Review recent endoscopy or colonoscopy findings to ensure the stoma or bowel is healthy and that odor is not a sign of an underlying infection or necrosis.
- Organ Function: While systemic absorption is low, a baseline LFT (Liver Function Test) is recommended for patients with known hepatic disorders.
- Screening: Evaluate the patient’s diet to identify high-sulfur foods (e.g., eggs, cabbage, onions) that may be contributing to excessive odor.
- Surgical Review: Confirm the type of ostomy and the current pouching system’s integrity to rule out mechanical leaks as the source of odor.
Monitoring and Precautions
- Vigilance: Patients should be monitored for any sudden changes in bowel habits or skin irritation near the stoma site if using topical formulations.
- Lifestyle: Encourage the consumption of yogurt or buttermilk, which can naturally help balance gut flora, alongside Chloresium therapy.
- Hydration: Maintain adequate water intake (at least 2 liters per day) to facilitate the movement of the complex through the GI tract.
Do’s and Don’ts for GI Health
- DO take the medication consistently at the same time each day for maximum effectiveness.
- DO inform your doctor if your stool color changes to something other than green or black (e.g., clay-colored or bright red).
- DON’T use Chloresium as a substitute for proper ostomy hygiene or regular pouch changes.
- DON’T panic if you see green discoloration in the stool; this is the expected result of the chlorophyllin pigment.
