Binds to the 30S ribosomal subunit, inhibiting aminoacyl-tRNA binding to the mRNA-ribosome complex, thereby blocking protein synthesis.
Robitussin (Robitet) is a combination product containing the antitussive dextromethorphan and the expectorant guaifenesin. Dextromethorphan acts centrally on the cough center in the medulla oblongata by increasing the threshold for coughing, primarily through sigma-1 receptor agonism and NMDA receptor antagonism. Guaifenesin increases the hydration of respiratory tract secretions, reducing mucus viscosity and facilitating expectoration.
