Pharmacodynamics properties
Analgesic- the mechanism of analgesic action has not been fully determined. Paracetamol may act by inhibiting prostaglandin synthesis in the central nervous system and through a peripheral action by blocking pain impulse generation.
The peripheral action may also be due to inhibition of prostaglandin synthesis or to the synthesis of other substances that sensitize pain receptors to mechanical or chemical stimulation.
Antipyretic- Paracetamol probably produces antipyresis by acting centrally on the hypothalamic heat-regulation center to produce peripheral vasodilation resulting in increased blood flow through the skin, Sweating and heat loss.
The central action probably involves inhibition of prostaglandin synthesis in the hypothalamus.
