Mechanism of Action

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. Phenylephrine is a vasoconstrictor and a decongestant that relieves symptoms resulting from irritation of upper respiratory tract tissue. It shrinks swollen mucous membranes, reduces nasal congestion and tissue hyperemia.
