What are selective serotonin reuptake inhibitors (SSRIs)?
SSRIs are called selective because they mainly affect serotonin, not other neurotransmitters. SSRIs may also be used to treat conditions other than depression, such as anxiety disorders. The Food and Drug Administration (FDA) has approved these SSRIs to treat depression:

What drug blocks reuptake of dopamine serotonin and norepinephrine?
SNRIs. Serotonin–norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine (Effexor), its active metabolite desvenlafaxine (Pristiq), and duloxetine (Cymbalta) prevent the reuptake of both serotonin and norepinephrine, however their efficacy appears to be only marginally greater than the SSRIs.

In reuptake a protein called a transporterMoreSSRIs work by inhibiting a mechanism called reuptake. In reuptake a protein called a transporter transports excess neurotransmitter molecules out of the synaptic cleft.
What happens when you inhibit reuptake of dopamine?
Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron. This results in increased extracellular concentrations of dopamine and increase in dopaminergic neurotransmission.
Does Wellbutrin block dopamine?
Bupropion is an ideal medication for the treatment of depression as it works by inhibiting the reuptake of dopamine, serotonin, and norepinephrine and helps balance out the neurotransmitter imbalance that causes depression.
Is Adderall a dopamine reuptake inhibitor?
Furthermore, resembling cocaine, Ritalin and Adderall are also monoamine reuptake inhibitors of dopamine, norepinephrine, and serotonin.
Do SSRIs deplete dopamine?
SSRI antidepressants work by boosting circulating levels of serotonin, a mood-regulating neurotransmitter that also inhibits desire. The drugs also decrease dopamine, a neurotransmitter involved in a wide range of cognitive and behavioral processes, among them desire and arousal.

List of SNRIs + Uses, Types & Side Effects - Drugs.com
SNRI stands for serotonin-norepinephrine reuptake Inhibitor. these may also be called selective serotonin-norepinephrine reuptake Inhibitors (SSNRIs). SNRIs increase levels of serotonin and norepinephrine in the brain by blocking or delaying their reuptake by nerves.
SSRIs | Psychology Today
Although SSRIs are primarily used to treat depression, they are commonly prescribed for the treatment of anxiety and related conditions. They have also been used to treat impulse-related disorders ...
What is selective serotonin reuptake inhibitor?
Selective serotonin reuptake inhibitors (SSRIs) This commonly prescribed type of antidepressant can help you overcome depression. Discover how SSRIs improve mood and what side effects they may cause. By Mayo Clinic Staff. Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants.
Why are SSRIs selective?
SSRIs are called selective because they mainly affect serotonin, not other neurotransmitters. SSRIs may also be used to treat conditions other than depression, such as anxiety disorders.
What is the purpose of SSRIs?
Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons. This makes more serotonin available to improve transmission of messages between neurons. SSRIs are called selective because they mainly affect serotonin, ...
What are the symptoms of serotonin syndrome?
Signs and symptoms of serotonin syndrome include anxiety, agitation, high fever, sweating, confusion, tremors, restlessness, lack of coordination, major changes in blood pressure and a rapid heart rate. Seek immediate medical attention if you have any of these signs or symptoms. Antidepressants and pregnancy.
What does a doctor take into account when choosing an antidepressant?
When choosing an antidepressant, your doctor takes into account your symptoms, any health problems, other medications you take and what has worked for you in the past.
Can SSRIs cause bleeding?
For example, SSRIs may increase your risk of bleeding, especially when you're taking other medications that increase the risk of bleeding, such as nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, warfarin (Coumadin, Jantoven) and other blood thinners. Serotonin syndrome.
Can SSRIs cause side effects?
Possible side effects and cautions. All SSRIs are thought to work in a similar way and generally can cause similar side effects, though some people may not experience any. Many side effects may go away after the first few weeks of treatment, while others may lead you and your doctor to try a different drug. If you can't tolerate one SSRI, you may ...
Which neurotransmitter is affected by reuptake inhibitors?
Most known reuptake inhibitors affect the monoamine neurotransmitters serotonin, norepinephrine (and epinephrine ), and dopamine. However, there are also a number of pharmaceuticals and research chemicals that act as reuptake inhibitors for other neurotransmitters such as glutamate, γ-aminobutyric acid (GABA), glycine, adenosine, choline (the precursor of acetylcholine ), and the endocannabinoids, among others.
How do reuptake inhibitors work?
Standard reuptake inhibitors are believed to act simply as competitive substrates that work by binding directly to the plasmalemma transporter of the neurotransmitter in question. They occupy the transporter in place of the respective neurotransmitter and competitively block it from being transported from the nerve terminal or synapse into the pre-synaptic neuron. With high enough doses, occupation becomes as much as 80–90%. At this level of inhibition, the transporter will be considerably less efficient at removing excess neurotransmitter from the synapse and this causes a substantial increase in the extracellular concentrations of the neurotransmitter and therefore an increase in overall neurotransmission .
What is the second type of reuptake inhibitor?
A second type of reuptake inhibition affects vesicular transport, and blocks the intracellular repackaging of neurotransmitters into cytoplasmic vesicles. In contrast to plasmalemmal reuptake inhibitors, vesicular reuptake inhibitors do not increase the synaptic concentrations of a neurotransmitter, only the cytoplasmic concentrations; unless, ...
What receptors does Hyperforin target?
Hyperforin and adhyperforin are wide-spectrum inhibitors of the reuptake of serotonin, norepinephrine, dopamine, glutamate, GABA, glycine, and choline, and they exert these effects by binding to and activating the transient receptor potential cation channel TRPC6.
What is escitalopram used for?
Escitalopram, a selective serotonin reuptake inhibitor (SSRI) used as an antidepressant. A reuptake inhibitor ( RI) is a type of drug known as a reuptake modulator that inhibits the plasmalemmal transporter -mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron. This leads to an increase in extracellular ...
What is the vesicular transporter substrate?
Vesicular transporter substrates. Reserpine, a vesicular reuptake inhibitor that was used in the past to deplete serotonin, norepinephrine, and dopamine stores as an antipsychotic and antihypertensive. It was notorious for causing anxiety and depression, and as a result, was replaced by newer, more modern drugs instead.
Which monoamines have a lower affinity for allosteric sites?
