How Pain Killers work

Pain management involves understanding how pain signals are created, transmitted, and perceived by the body. Pain signals start at nociceptors and travel through fiber axons to the cerebral cortex.

How Pain Killers work

-Where the pain signal is created

-Paracetamol acts a reducing co-substrate to POX -Works well in low arachidonic acid levels to inhibit POX -In high levels it weakly inhibits POX

-Slows the prostaglandin formation -Inhibits cyclooxygenase (COX) -Blocks nociceptor activation

-Work by bonding to the opioid receptors -Mimic endorphins -Aid with opening of potassium channels -Block the opening of calcium channels -End result is inhibiting the ability to transmit the pain signal

-Signal travels to the cerebral cortex -Travels via Fiber axons -2 kinds of axons -Type A -Type C

- Release of prostaglandin

Paracetamol

-Work similar to NSAIDs by blocking prostaglandin formation -Lack of strong anti-inflammatory effect

-2 step process to form prostaglandin -COX produces prostaglandin G2 from arachidonic acid -Peroxidase (POX) converts to prostaglandin H2

NSAIDs

Opioids

Nociceptors

-Nociceptors releases a signal in the form of action potienal

Modulation

- Where the body interacts with nerves to deal with the pain -Releases endorphins or serotonin

Perception

-Where you become aware of the pain

Transmission

Transduction
