Belladonna Alkaloids / Chlorpheniramine / Phenylephrine / Phenylpropanolamine
This combination medication contains four active ingredients that work together to relieve symptoms of the common cold, allergies, and sinus congestion. Belladonna alkaloids provide anticholinergic effects to reduce excessive respiratory secretions and relax smooth muscles, while chlorpheniramine acts as an antihistamine to address sneezing, runny nose, and itchy eyes. Phenylephrine and phenylpropanolamine function as decongestants by constricting blood vessels in the nasal passages, thereby decreasing swelling and congestion.
A multi-symptom cold and allergy medication combining anticholinergic, antihistamine, and decongestant properties to address congestion, allergic symptoms, and excessive secretions.
