Role of Guaifenesin in Managing Chest and Throat Congestion
Guaifenesin is an expectorant or mucoactive drug that unlaces the mucus present in the nasal airways. It is used for symptomatic management of chest congestion and wet cough caused by common cold, allergies, or infections.  Guaifenesin uses are wider in fact, it is a standalone all-in-one medication for cold and cough. Food and Drug Administration (FDA) has approved this drug as the only expectorant since 1952. (1)

Molecular Formulae – C10H14O4

Molecular Weight – 198.22 g/mol

How does it Works?

Guaifenesin mechanism of action has an expansive reaction on the mucociliary mechanism by removing gathered secretion in the airways. This is an expectorant with glyceryl guaiacolate. It stimulates mucus secretion in the respiratory tract. It irritates the gastric vagal receptors and efferent parasympathetic reflexes, which are responsible for glandular exocytosis. This is an agent that decreases the viscosity of the secreted mucus. The process is done by reducing surface tension, adhesiveness, and increasing mucus hydration. (2)

It acts as:

  • Decongestants – It alleviates blocked nose by constricting blood vessels inside the nasal passage. As a result, the size of the airway increases, and the patient can breathe well.
  • Cough Suppressants – It directly acts on the nerve center of the brain, which stimulates coughing. It hydrates the mucus to lower the stickiness. Therefore, the patient can cough easily.

How to Use This Drug?

Guaifenesin tablets or syrups are generally taken as an over-the-counter drug and also as prescription medicine. It can be taken after every four hours. 200 to 400 mg after every four hours is advisable for adults. It must not exceed 2.4 g/day. This can give instant relief. 600 to 1200 mg after every 12 hours can be taken for sustained release.

Pediatric dosage may vary from 50 mg to 1200 mg based on age bracket and clinical condition. One must always consult a doctor before taking any medicine, as wrong dosage or excessive use may incur other morbidities. (3)
