Usage
- This combination medication is prescribed for the symptomatic relief of common cold and flu symptoms, including cough (particularly productive cough), nasal and chest congestion, runny nose, sneezing, and itchy or watery eyes. It is indicated for productive coughs where thinning of mucus is beneficial.
- Pharmacological Classification: This is a combination product containing drugs from different classifications:
- Bromhexine: Mucolytic
- Chlorpheniramine: Antihistamine
- Ephedrine: Decongestant, Bronchodilator
- Guaifenesin: Expectorant
- Mechanism of Action: This combination works by thinning and loosening mucus (Bromhexine, Guaifenesin), reducing allergic responses like sneezing and runny nose (Chlorpheniramine), and relieving nasal congestion by constricting blood vessels (Ephedrine). Ephedrine also acts as a bronchodilator.
Alternate Names
- There is no internationally recognized non-proprietary name for this specific four-drug combination. Brand names vary regionally. It’s sometimes referred to as a cough and cold preparation.
- Some brand names include: Sudin Plus. More brand names may exist depending on the region and specific manufacturer.
How It Works
- Pharmacodynamics:
- Bromhexine: Depolymerizes mucopolysaccharides, reducing mucus viscosity.
- Chlorpheniramine: Antagonizes histamine H1 receptors.
- Ephedrine: Stimulates alpha and beta-adrenergic receptors, leading to vasoconstriction and bronchodilation.
- Guaifenesin: Increases respiratory tract fluid secretions.
- Pharmacokinetics: Absorption, metabolism, and elimination data for this specific combination are limited. Individual drug components have the following characteristics:
- Bromhexine: Well-absorbed orally, metabolized in the liver, and excreted renally.
- Chlorpheniramine: Well-absorbed orally, metabolized in the liver, and excreted renally.
- Ephedrine: Readily absorbed orally, partially metabolized in the liver, and excreted renally.
- Guaifenesin: Readily absorbed orally, metabolized in the liver, and excreted renally.
- Mode of Action:
- Bromhexine: Acts on the mucus at a molecular level, breaking down the long chain-like structures, making it thinner and less sticky.
- Chlorpheniramine: Blocks the action of histamine at H1 receptors, reducing allergic symptoms.
- Ephedrine: Stimulates adrenergic receptors, causing vasoconstriction in the nasal passages and bronchodilation in the airways.
- Guaifenesin: Irritates the gastric mucosa, indirectly increasing respiratory tract secretions, thus thinning mucus.
- Elimination Pathways: Primarily renal excretion for all components, with varying degrees of hepatic metabolism.
