GUAIPHENESIN: A Wonder Drug for the Respiratory System | | Anzen Exports

GUAIPHENESIN

Guaiphenesin is the only medicinal product in common use as an expectorant. It’s an ingredient that a great many cough medicines contain, such as Anti-Tuss, Dristan cold and cough, Guaifed, Guaicough, and a few of Robitussin products.

Guaifenesin may be a glyceryl guaiacolate with expectorant effects. The secretions of the mucus act as an irritant to gastric vagal receptors and recruit different parasympathetic reflexes that cause glandular exocytosis.

This agent reduces the viscosity of mucus secretion by reducing adhesiveness and natural phenomenon also by increasing the hydration of mucus. (PubChem)

 

Molecular Formula: C10H14O4

The Wonder Drug

Opera singers sometimes refer to guaifenesin as the “wonder drug” for its ability to market secondary mucosal secretion within the respiratory system. Secondary mucus is the thinner, lubricating mucus that happens on the vocal folds naturally once they are healthy and well hydrated. Singers use guaifenesin to reinforce the state of their vocal folds in the extremes of humidity, very humid or very dry, after flying long distances, or through mild allergies. (Bitao’s Research Group)

In the News

An extended-release (ER) formulation of the medication guaifenesin has recently been launched in the Republic of India for the treatment of productive cough amid secretion (phlegm).

A prospective, post-marketing police work-study listened to 552 adults with cough, thickened secretion and chest congestion because of URTI, who took ER guaifenesin 1200 mg every 12 hrs for seven days.

A total of twenty-nine treatment-emergent AEs were recorded in 28/552 patients, as well as the gastrointestinal, nervous system, psychiatric, respiratory, thoracic and mediastinal, skin and subcutaneous tissue, and general disorders.

All AE’s were delicate in severity and no serious AEs or deaths occurred.

The majority of each patient and investigators were either happy or very satisfied with enhancements in treatment outcomes.

 

Conclusion: This study found that ER guaifenesin was well tolerated and had a positive safety profile in otherwise healthy patients plagued by symptoms of cough, thickened secretion and chest congestion associated with URTI.
