A synapse during re-uptake. Note that some neurotransmitters are lost and not reabsorbed. Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.
Escitalopram, a selective serotonin reuptake inhibitor (SSRI) used as an antidepressant.. Reuptake inhibitors (RIs) are a type of reuptake modulators.It is a drug that inhibits the plasmalemmal transporter-mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron.
A variety of neurotransmitter reuptake transporters are pharmacotherapeutic targets for modulating the synaptic neurotransmitter concentration, and therefore neurotransmission. Antidepressants such as SSRIs , SNRIs and TCAs suppress the activity of serotonin and/or norepinephrine transporters, preventing the reuptake of targeted ...
The primary function of most neurotransmitter transporters is to facilitate neurotransmitter reuptake (i.e., the reabsorption of neurotransmitters by the cell which released them). [ 1 ] [ 2 ] [ 6 ] During neurotransmitter reuptake, neurotransmitter transporters will move specific types of neurotransmitters from the extracellular space into the ...
NET is a monoamine transporter and is responsible for the sodium-chloride (Na + /Cl −)-dependent reuptake of extracellular norepinephrine (NE), which is also known as noradrenaline. NET can also reuptake extracellular dopamine (DA). The reuptake of these two neurotransmitters is essential in regulating concentrations in the synaptic cleft ...
Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the ...
Triple re-uptake inhibitors act by blocking DATs, NETs, and SERTs simultaneously. Most modern antidepressant drugs work on the principle of blocking re-uptake transporters. SSRI's such as Fluoxetine (Prozac) and SNRI's as with Venlafaxine are the main types of drugs given in first line depression and anxiety treatment.
Selective serotonin reuptake inhibitors (SSRIs) selectively inhibit the reuptake of serotonin and are a widely used group of antidepressants. [31] With increased receptor selectivity compared to TCAs, undesired effects such as poor tolerability are avoided. [29] Serotonin is synthesized from an amino acid called L-tryptophan.
