Comparative Efficacy of the Suppository Versus Guaiacol Suppository Versus Guaifenesin Syrup in Pediatric Patients With Cough Due the Infectious Origin

Comparative Efficacy of the Suppository Composed by Guaiacol, Eucalyptol, Menthol and Camphor Versus Guaiacol Suppository Versus Guaifenesin Syrup in Pediatric Patients With Cough Due the Infectious Origin

It is believed that the suppository consisting of guaiacol, menthol, camphor and eucalyptol, by their pharmacological properties already established for each component, has the ability to reduce the signs and symptoms related to upper respiratory infections in a manner equivalent (not inferior) to medicine used as a comparator in this study and higher than the suppository containing only guaiacol concentration of 12.5 mg.
