Ambroxol + Levocetirizine + Paracetamol

Usage

This combination medication is primarily prescribed for the symptomatic relief of the common cold and flu. It addresses symptoms like cough, runny nose, sneezing, nasal congestion, headache, fever, and watery eyes. It is also used for some allergies, such as allergic rhinitis.

It’s pharmacological classifications include:

• Ambroxol: Mucolytic, expectorant
• Levocetirizine: Antihistamine
• Paracetamol: Analgesic, antipyretic

Mechanism of Action:

• Ambroxol: Reduces the viscosity of mucus by breaking down mucopolysaccharides, facilitating expectoration.
• Levocetirizine: Blocks histamine H1 receptors, relieving allergic symptoms.
• Paracetamol: Inhibits prostaglandin synthesis, reducing pain and fever.

Alternate Names

No widely recognized alternate names exist for this specific three-drug combination. The individual components may have other names (e.g., acetaminophen for paracetamol). Brand names vary depending on the manufacturer and region. Some example brand names include Covel-Plus and others.

How It Works

Pharmacodynamics:

• Ambroxol: Stimulates serous cells in the bronchial mucosa, increases surfactant production, and improves ciliary activity. It may also have some anti-inflammatory and antioxidant effects.
• Levocetirizine: Selectively antagonizes peripheral H1 receptors, reducing vascular permeability, edema, and itching. It is the active enantiomer of cetirizine.
• Paracetamol: Centrally inhibits COX enzymes, reducing prostaglandin synthesis, leading to antipyretic and analgesic effects. Its effect on COX enzymes in peripheral tissues is minimal.

Pharmacokinetics:

• Ambroxol: Well-absorbed orally. Metabolized in the liver and excreted mainly in the urine.
• Levocetirizine: Rapidly absorbed after oral administration. Minimally metabolized and primarily excreted unchanged in the urine.
• Paracetamol: Almost completely absorbed from the gastrointestinal tract. Metabolized primarily in the liver (glucuronidation and sulfation) and excreted in the urine. A minor pathway produces a hepatotoxic metabolite (NAPQI), which is usually detoxified by glutathione.

Dosage

Standard Dosage

Adults: The standard dose varies depending on the specific formulation and manufacturer’s recommendations. Refer to the brand-specific instructions for the exact dosage.

Children: Dosage is dependent upon age and weight. Not generally recommended for children under 6 years old. Consult a pediatrician for specific pediatric dosing recommendations.

Special Cases:

• Elderly Patients: Start with lower doses and adjust as needed, considering renal and hepatic function.
• Patients with Renal Impairment: Dose reduction may be required.
• Patients with Hepatic Dysfunction: Dose reduction may be required.
• Patients with Comorbid Conditions: Exercise caution and adjust dosage as needed, especially in patients with cardiovascular disease, diabetes, or enlarged prostate.

Clinical Use Cases

Dosage recommendations for specific medical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations are not well-established for this combination. Its usage is mainly for symptomatic relief in out-patient settings.

Dosage Adjustments

Dosage modifications are based on patient-specific factors like renal or hepatic dysfunction. Always consider potential drug interactions and comorbid conditions when adjusting the dose.
