Mechanism of Action (MOA)

Cheston Cold contains cetirizine, paracetamol, and phenylephrine that work together producing desirable effects. Paracetamol in Cheston Cold tablets works by blocking the synthesis of prostaglandins increasing the threshold of pain. This is effected by inhibiting the action of cyclooxygenases, enzymes involved in the synthesis of prostaglandins. Paracetamol also affects the heat centers directly in the hypothalamus, as a result enhancing peripheral vasodilation, sweating that encourages loss of heat. Paracetamol is an analgesic as it relieves pain and an antipyretic as it reduces fever.

cold flu symptomsCetirizine a second generation antihistamine works by antagonizing the actions of histamine. Thus cetirizine achieves by competing for the H1 receptor sites found on the effector cells. Allergic symptoms are usually as a result of histamine production and its action on effector cells. Once actions of histamine are inhibited, allergic symptoms are under control. Cetirizine also has anticholinergic effects, this causes the drying of the nasal mucosa. It also blocks bronchoconstriction in asthmatic attack patients that are induced by histamine.

Phenylephrine is classified as a sympathomimetic amine, it acts as an alpha – adrenergic receptors. It is a vasoconstrictor. It is mainly utilized in nasal decongestion and as a cardiotonic agent. When administered parentally it leads to a rise in systole and diastole pressure, lowering cardiac output while increasing peripheral resistance and blood flow in the coronary. It also causes an increase in pressure in pulmonary by constricting the pulmonary vessel. It increases the drainage of sinuses in the respiratory tract by vasoconstricting their mucosa. It also reduces the amount of blood flowing to the nose, thus decongesting the nasal cavity.
