Usage
This combination medication is primarily prescribed for the symptomatic relief of respiratory tract infections, such as the common cold, bronchitis, and allergies, accompanied by productive cough and congestion. It addresses both the congestion and allergic components of these conditions.
Pharmacological Classification:
- Ambroxol: Mucolytic, expectorant
- Guaifenesin: Expectorant
- Levocetirizine: Antihistamine
- Menthol: Topical analgesic, decongestant
Mechanism of Action:
Ambroxol and Guaifenesin work synergistically to thin and loosen mucus, facilitating its expulsion from the airways. Levocetirizine, a second-generation antihistamine, blocks histamine H1 receptors, mitigating allergic symptoms like runny nose, sneezing, and watery eyes. Menthol provides a cooling and soothing sensation, relieving minor throat irritation.
Alternate Names
This combination is typically referred to by its constituent drug names. There may be regional variations.
Brand Names: A few examples (this list may not be exhaustive):
- Aftercold AX

How It Works
Pharmacodynamics:
- Ambroxol: Reduces mucus viscosity by breaking down mucopolysaccharides. It also has some anti-inflammatory and antioxidant properties.
- Guaifenesin: Increases the volume and reduces the stickiness of respiratory secretions, promoting easier clearance.
- Levocetirizine: Selectively antagonizes peripheral H1 receptors, reducing the effects of histamine release. Minimal sedative effect compared to first-generation antihistamines.
- Menthol: Stimulates cold receptors, creating a cooling sensation and relieving minor throat discomfort. It also has mild decongestant properties.
Pharmacokinetics:
- Absorption: All components are readily absorbed from the gastrointestinal tract.
- Metabolism: Primarily hepatic metabolism, although specific pathways can vary by component (e.g., CYP3A4 for levocetirizine).
- Elimination: Primarily renal excretion, with some biliary excretion.
Dosage
Standard Dosage
Adults:
5-10 ml three times a day.
Children:
Dosage varies with age and weight, generally 2.5-5 ml based on age range as directed by physician. Refer to specific product guidelines for accurate pediatric dosing.
Special Cases:
- Elderly Patients: Start with a lower dose and adjust based on tolerance and renal function.
- Patients with Renal Impairment: Dose reduction may be necessary.
- Patients with Hepatic Dysfunction: Dose adjustments are needed, particularly for Levocetirizine.
- Patients with Comorbid Conditions: Careful evaluation and monitoring are required, especially for those with cardiovascular disease, diabetes, or other metabolic disorders.
