Usage
-
Mecetronium is primarily prescribed as a topical antiseptic for hygienic and surgical hand disinfection and skin disinfection prior to injections, punctures, or surgical procedures. It exhibits broad-spectrum antimicrobial activity against bacteria, fungi, and certain viruses.
-
Pharmacological Classification: Antiseptic.
-
Mechanism of Action: Mecetronium is a quaternary ammonium compound that disrupts the cell membranes of microorganisms, leading to their inactivation or death.
Alternate Names
How It Works
-
Pharmacodynamics: Mecetronium exerts its antiseptic effect by disrupting the cell membranes of a wide range of microorganisms. This disruption causes leakage of cellular contents and ultimately leads to microbial death. It has a rapid onset of action.
-
Pharmacokinetics: Mecetronium is intended for topical application only. Absorption through intact skin is minimal. When used as directed, systemic exposure is negligible. Metabolism and elimination pathways have not been extensively studied due to the limited systemic absorption.
-
Mode of Action: Mecetronium acts as a cationic surfactant, interacting with the negatively charged phospholipids in microbial cell membranes. This interaction disrupts the membrane integrity, causing increased permeability and leakage of intracellular components.
-
Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: No significant interaction with specific receptors, enzymes, or neurotransmitters has been reported.
-
Elimination Pathways: Primarily eliminated through evaporation from the application site after topical use. Any minimal absorbed drug is likely excreted through renal or hepatic pathways.
Dosage
Standard Dosage
Adults:
-
Hygienic Hand Disinfection: Apply at least 3 ml to dry hands and rub for 30 seconds. Allow to air dry. Do not rinse.
-
Surgical Hand Disinfection: Apply sufficient solution to thoroughly cover dry hands and forearms. Rub for at least 1.5 minutes, keeping hands and forearms wet. Allow to air dry. Do not rinse.
-
Skin Disinfection: Apply to the dry skin area and rub for 15 seconds before injections or punctures. For punctures of joints, body cavities, or surgical interventions, keep the area wet for 1 minute. For skin with high sebaceous gland concentration, maintain wetness for 10 minutes.
Children:
- Limited data available. Not generally recommended for use in newborns or premature infants. For older children, use with caution and under the guidance of a healthcare professional. Adjust the amount applied based on the size of the area to be disinfected.
Special Cases:
- Elderly Patients: No specific dosage adjustments are generally required.
- Patients with Renal Impairment: No specific dosage adjustments are required due to minimal systemic absorption.
- Patients with Hepatic Dysfunction: No specific dosage adjustments are required due to minimal systemic absorption.
- Patients with Comorbid Conditions: No specific dosage adjustments are typically needed.
Clinical Use Cases
- Intubation, Surgical Procedures, Mechanical Ventilation, ICU Use, Emergency Situations: Follow standard skin disinfection guidelines as outlined above.
Dosage Adjustments
- No specific dosage adjustments are generally needed based on renal/hepatic function, metabolic disorders, or genetic polymorphisms due to minimal systemic absorption.
Side Effects
Common Side Effects:
- Dryness of skin
- Skin irritation
Rare but Serious Side Effects:
- Allergic reactions (e.g., contact dermatitis)
Long-Term Effects:
- No significant long-term effects are anticipated with topical use as directed.
Adverse Drug Reactions (ADR):
- Severe allergic reactions (e.g., anaphylaxis) – rare.
Contraindications
- Hypersensitivity to mecetronium or any component of the formulation.
- Application to mucous membranes, open wounds, or near the eyes.
- Use in newborns or premature infants.
Drug Interactions
- Clinically significant drug interactions are not known.
Pregnancy and Breastfeeding
- Pregnancy: Safety during pregnancy has not been established. Use with caution and only if clearly needed.
- Breastfeeding: Safety during breastfeeding is unknown. Avoid applying to areas that may come into contact with the infant’s mouth.
Drug Profile Summary
- Mechanism of Action: Disrupts microbial cell membranes.
- Side Effects: Dry skin, irritation, rarely allergic reactions.
- Contraindications: Hypersensitivity, application to mucous membranes/open wounds, newborns/premature infants.
- Drug Interactions: Not known.
- Pregnancy & Breastfeeding: Safety not established. Use with caution.
- Dosage: See detailed dosage guidelines above.
- Monitoring Parameters: Observe for skin irritation or allergic reactions.
Popular Combinations
- Often combined with other antiseptics like propanol (e.g., in Sterillium). This combination enhances the broad-spectrum antimicrobial activity.
Precautions
- Avoid contact with eyes and mucous membranes.
- Flammable. Keep away from open flames and ignition sources.
- For external use only.

Q3: Is Mecetronium safe to use during pregnancy?
A: The safety of Mecetronium during pregnancy hasn’t been definitively established. Use with caution and only if the potential benefits outweigh the risks.
Q4: Can Mecetronium be used near the eyes?
A: No, avoid applying Mecetronium near the eyes.
Q5: What should be done if Mecetronium gets into the eyes?
A: Immediately flush the eyes with plenty of water for at least 15 minutes and seek medical advice.
Q6: Can Mecetronium be used as a hand sanitizer?
A: Yes, Mecetronium is commonly used as a component in hand sanitizers, particularly in combination with alcohols like propanol.
Q7: What are the most common side effects of Mecetronium?
A: The most common side effects are mild skin dryness and irritation.
Q8: What should I do if I experience an allergic reaction to Mecetronium?
A: Discontinue use immediately and consult a healthcare professional. Severe allergic reactions may require emergency medical treatment.
Q9: Is Mecetronium effective against viruses?
A: Mecetronium is effective against certain viruses, but it’s important to note that its virucidal activity may be limited. It’s most effective against enveloped viruses. Always follow the manufacturer’s instructions for appropriate contact time.
