31. Esmolol prevents the action of two naturally occurring substances : epinephrine and norepinephrine . 32. The sequential binding of the ions results in the eventual reuptake of norepinephrine . 33. Norepinephrine modulates the intensity of central reactions to vestibular stimulation and facilitates compensation.34. They have receptors for insulin, sexual hormones, norepinephrine , and glucocorticoids. 35. It is cardiac norepinephrine , and inactivates tyrosine hydroxylase. 36. Norepinephrine in the brain is produced by neurons and stays in the brain.37. Norepinephrine degradation . 3, 4-Dihydroxymandelic acid is shown at right.38. Monoamines are neurotransmitters that include serotonin, dopamine, norepinephrine , and epinephrine. 39. The adrenal medulla produces epinephrine ( adrenaline ) and norepinephrine ( noradrenaline ). 40. Meridia also boosts the level of a hormone known as norepinephrine , Knoll said.
