The sympathetic effects of norepinephrine include: In the eyes, an increase in the production of tears, making the eyes more moist, [19] and pupil dilation through contraction of the iris dilator. In the heart, an increase in the amount of blood pumped. [20] In brown adipose tissue, an increase in calories burned to generate body heat ...
Norepinephrine Epinephrine. A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET).
Medicines that affect norepinephrine (e.g. venlafaxine, imipramine, mirtazapine) should be used with caution when administered with atomoxetine due to possible synergy or synergistic effects on pharmacodynamic effects. Beware of taking reboxetine in combination with: [9] Antifungals, e.g. ketoconazole. Antibiotics, e.g. erythromycin, rifampicin.
Neurotransmitters play essential roles in stimulating and inhibiting the processes that lead to libido production in both men and women. For instance, a positive stimulation is modulated by dopamine from the medial preoptic area in the hypothalamus [2] and norepinephrine.

Still, not everyone benefits from drugs that work on monoamines. The development of esketamine ( Spravato ) has helped shift attention beyond these neurotransmitters altogether.
It is the same molecule as the hormone and neurotransmitter norepinephrine. [2] It is given by slow injection into a vein. [2] Common side effects include headache, slow heart rate, and anxiety. [2] Other side effects include an irregular heartbeat. [2] If it leaks out of the vein at the site it is being given, norepinephrine can result in limb ...
Ephedrine, one of the most well-known selective NRAs.. A norepinephrine releasing agent (NRA), also known as an adrenergic releasing agent, is a catecholaminergic type of drug that induces the release of norepinephrine (noradrenaline) and epinephrine (adrenaline) from the pre-synaptic neuron into the synapse.
