In children epinephrine or norepinephrine is generally preferred while in adults norepinephrine is generally preferred for very low blood pressure. [6] [7] It is given intravenously or intraosseously as a continuous infusion. [4] Effects typically begin within five minutes. [4] Doses are then increased to effect. [4]
Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD.Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training ...

Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain.
In those with dopamine-responsive dystonia, symptoms typically dramatically improve with low-dose administration of levodopa, which is a biochemically significant metabolite of the amino acid phenylalanine, as well as a biological precursor of the catecholamine dopamine, a neurotransmitter. (Neurotransmitters are naturally produced molecules ...
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron.
Dopamine receptor flow chart. Dopamine receptors are all G protein–coupled receptors, and are divided into two classes based on which G-protein they are coupled to. [1] The D 1-like class of dopamine receptors is coupled to Gα s/olf and stimulates adenylate cyclase production, whereas the D 2-like class is coupled to Gα i/o and thus inhibits adenylate cyclase production.
A dopamine agonist is a compound that activates dopamine receptors. There are two families of dopamine receptors, D 1-like and D 2-like. They are all G protein-coupled receptors. D 1 - and D 5-receptors belong to the D 1-like family and the D 2-like family includes D 2, D 3 and D 4 receptors. [1]
