Usha Rani Kandula, an assistant professor from Arsi University in Ethiopia, authored this document about expectorants. Expectorants are drugs that increase fluid in the respiratory tract and thin secretions to aid in removal through coughing and cilia action. Common expectorants include guaifensin, potassium iodide, and terpin hydrate elixir. Expectorants are indicated for non-productive coughs, bronchitis, laryngitis, influenza, dry coughs, and productive coughs. Nurses assess lung sounds, cough characteristics, secretions and encourage fluid intake and deep breathing exercises when clients take expectorants.
