Usage
- This combination medication is primarily prescribed for the symptomatic relief of cough with mucus (productive cough) associated with respiratory tract infections like the common cold, bronchitis, and sinusitis. It helps to thin and loosen mucus, making it easier to cough up, while also addressing allergic symptoms that can exacerbate cough.
- Pharmacological Classification: This is a combination drug containing a mucolytic (ambroxol), an antihistamine (desloratadine), an expectorant (guaifenesin), and a topical decongestant (menthol).
- Mechanism of Action: Ambroxol breaks down mucus, decreasing its viscosity. Guaifenesin increases respiratory tract fluid secretions, aiding mucus expulsion. Desloratadine blocks histamine action, reducing allergic symptoms. Menthol creates a cooling sensation, easing throat irritation and providing decongestant effects.
Alternate Names
- No widely recognized alternate names exist for the combination itself. However, each component has its own generic and brand names.
- Brand Names: Brand names vary depending on the manufacturer and region. Some examples include Alde AM Syrup, Brexvin Suspension, Coftime Syrup, Koftrodex Syrup, New Torex-AP Cough Syrup (Note: Availability of brand names may vary by region and time).
How It Works
- Pharmacodynamics: Ambroxol acts as a mucolytic, reducing mucus viscosity. Guaifenesin is an expectorant, increasing respiratory secretions. Desloratadine, an antihistamine, blocks H1 receptors, mitigating allergic responses like runny nose and sneezing. Menthol activates cold-sensitive receptors, producing a cooling sensation and acting as a mild local anesthetic and decongestant.
- Pharmacokinetics:
- Ambroxol: Well-absorbed orally. Metabolized in the liver and excreted primarily in urine.
- Desloratadine: Well-absorbed orally. Extensively metabolized in the liver, primarily by CYP3A4 and CYP2D6. Eliminated through urine and feces.
- Guaifenesin: Readily absorbed from the gastrointestinal tract. Metabolized in the liver and excreted in urine.
- Menthol: Absorbed through skin and mucous membranes. Metabolized in the liver and excreted primarily in urine.
- Mode of Action: Ambroxol alters the structure of mucopolysaccharides, reducing mucus viscosity. Guaifenesin increases respiratory tract fluid, thinning mucus. Desloratadine competitively inhibits histamine binding to H1 receptors. Menthol activates TRPM8 receptors, leading to a cooling sensation.
- Elimination Pathways: All four components are primarily metabolized in the liver and excreted predominantly in urine.
