Mechanism of Action

Chlorpheniramine blocks muscle responses in histamine and acts as an antagonism of the constrictor effects of histamine on respiratory smooth muscle. Acetaminophen blocks pain impulse generation peripherally and may inhibit the generation of prostaglandin in the CNS. Reduces fever by inhibiting the hypothalamic heat-regulating center. Pseudoephedrine stimulates the alpha-adrenergic receptors causing bronchodilation and vasoconstriction.
