These receptors are involved in the perception of pain and the regulation of pain signals.
Inhibition of Norepinephrine and Serotonin Reuptake: Tramadol also inhibits the reuptake of the neurotransmitters norepinephrine and serotonin in the brain. This action increases the levels of these neurotransmitters, which can contribute to pain relief and a sense of well-being.
