Overview
Actihist Expectorant is a combination expectorant formula containing pseudoephedrine (a decongestant) and triprolidine (a first-generation antihistamine), used to relieve nasal congestion, allergy symptoms, and a stuffy, congested chest associated with the common cold and flu, marketed as a 3-in-1 formula through its combined decongestant and antihistamine action.
Pseudoephedrine narrows swollen blood vessels in the nasal passages to reduce congestion, while triprolidine blocks histamine receptors to relieve sneezing, itching, and watery eyes caused by allergic or cold-related reactions.
How it Works
Pseudoephedrine acts as a sympathomimetic, stimulating alpha-adrenergic receptors in the nasal mucosa to constrict blood vessels and reduce swelling and mucus production, while triprolidine competitively blocks H1-histamine receptors, reducing the allergic and inflammatory symptoms that contribute to congestion and a runny nose.
