Mechanism of Action
Chlorpheniramine blocks muscle responses in histamine and acts as an antagonism of the constrictor effects of histamine on respiratory smooth muscle
Paracetamol blocks pain impulse generation peripherally and may inhibit the generation of prostaglandin in the CNS. Reduces fever by inhibiting the hypothalamic heat-regulating center
Dextromethorphan is a cough suppressant that acts centrally on the cough center in the medulla
