Guanendrux
Guanendrux is a combination medication that includes guaifenesin, an expectorant, and dextromethorphan, a cough suppressant. It is primarily used to relieve symptoms associated with coughs and congestion caused by colds, bronchitis, and other respiratory conditions. Guaifenesin helps loosen mucus in the airways, making it easier to cough up, while dextromethorphan reduces the urge to cough.
