Study Notes
Antidepressants and Neurotransmitters
- Tricyclic Antidepressants (TCAs) primarily inhibit the active reuptake of neurotransmitters to the presynaptic membrane.
- In depression, the neurotransmitters primarily affected are serotonin, norepinephrine, and dopamine, leading to decreased levels in both presynaptic and postsynaptic membranes.
- Monoamine Oxidase Inhibitors (MOAIs) inhibit the enzyme monoamine oxidase to increase the levels of neurotransmitters.
- The primary role of neurotransmitters in the brain for a normal person is to transmit signals between neurons.
- In depression, the levels of neurotransmitters decrease, leading to impaired transmission of signals between neurons.
- Selective Serotonin Reuptake Inhibitors (SSRIs) inhibit the reuptake of serotonin, increasing its levels in the synaptic cleft.
- Monoamino Oxidase Inhibitors (MOAIs) are known for inhibiting the enzyme monoamine oxidase to increase the levels of neurotransmitters.
