guaifenesin + doxylamine succinate + etafedrine hydrochloride

This is a **combination drug** containing three active ingredients commonly used to treat symptoms associated with cough, upper respiratory congestion, and bronchospasm: - **Guaifenesin** is an expectorant that helps thin and loosen mucus in the airways, making it easier to clear from the respiratory tract. - **Doxylamine succinate** is a first-generation antihistamine with anticholinergic and sedative properties, often used to reduce symptoms such as runny nose and sneezing associated with upper respiratory tract infections. - **Etafedrine hydrochloride** is a sympathomimetic agent and selective beta-2 adrenoceptor agonist, structurally related to ephedrine, which acts as a bronchodilator and has decongestant activity, thereby relieving bronchospasm and nasal congestion. This combination is not widely marketed under a single well-known brand name and appears in the medical literature for treatment of respiratory conditions such as chronic bronchitis, and bronchospasm, and may also be used for cough and cold symptoms. It is formulated as an **oral pharmaceutical** and is typically used for symptomatic respiratory relief in conditions involving cough, mucus hypersecretion, or bronchospasm[1][7].
