pseudoephedrine + chlorpheniramine + belladonna alkaloids

This is a combination drug consisting of **pseudoephedrine**, **chlorpheniramine**, and **belladonna alkaloids**. - **Pseudoephedrine** is a sympathomimetic amine that acts as an alpha and beta adrenergic receptor agonist, leading to vasoconstriction and decongestion of nasal passages. - **Chlorpheniramine** is a first-generation antihistamine that acts as an antagonist at H1 histamine receptors, reducing the symptoms of allergies such as sneezing, itching, and runny nose. - **Belladonna alkaloids** are antimuscarinic agents (typically including atropine, hyoscyamine, and scopolamine) that produce anticholinergic effects such as reduction in glandular secretions, relaxation of smooth muscles, and antispasmodic actions. This combination is generally intended for symptomatic relief in upper respiratory conditions such as the **common cold**, **allergic rhinitis**, and related conditions where decongestion, antihistaminic, and antispasmodic effects are beneficial[2][3][5][7].
