MODE OF ACTION

How paracetamol controls fever?

Normal body temperature is 98.6 F, which is regulated by hypothalamus (brain)
When infection occurs, there is increase secretion of prostaglandin
Which causes disturbance in hypothalamus & due to that temperature increases called fever
After taking paracetamol, this medicine blocks the synthesis of prostaglandin

 

So, for period of time hypothalamus works well & temperature decreases.

This way paracetamol decreases the temperature for short period of time. Other medicines will control the infection. 

How paracetamol controls the pain?

It causes nerve stimulation & so, we feel pain
After taking paracetamol, it blocks the synthesis of prostaglandin

 

So, brain not recieved the message of pain temporarily. 

This way paracetamol controls pain. With time injured part heal & patient will feel completely okay.
