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
Pseudoephedrine: stimulates the alpha-adrenergic receptors causing bronchodilation & vasoconstriction
Guaifenesin: increases respiratory tract fluid secretions and helps to loosen phlegm and bronchial secretions
