Cough research study

What is the primary objective of this study?

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.
