Q

How do SSRIs biologically work?

A

They increase levels of serotonin in the synapse by blocking the process of reuptake (reabsorption into the presynaptic neuron)
Serotonin then continues to bind with the post synaptic receptors to help regulate mood and anxiety

Q

Which neurotransmitters do benzodiazepines work on?

A

GABA (inhibitory neurotransmitter)
Makes the post synaptic neuron less likely to fire an action potential as it creates a negative charge at cell membrane to reduce neuronal activity and have a calming effect

Q

How do benzodiazepines biologically work?

A

They make the post synaptic neuron less likely to fire an action potential (as it creates a negative charge at the cells membrane which reduces neuronal activity and has a calming effect)
They increase activity levels of GABA so there is an enhanced calming effect
