A

Oral Agoniste direct faible sur réc. alpha et beta

Q

Effet des psychostimulants?

A

have a similar action to pseudoéphédrine -> increase NA and Dopamine in the brain
they do this by competitevely binding to the clearance mechanisms for NA and Dopamine (degradation of MAO + vesicle removal)
other methods include:
recapture inhibition
neuroTransmitter biosyntehsis stimulation
degradation enzyme inhibition
leads to more NA and Dopamine available to act!!

Hause cytoplasmique de NA et DA (either by blocking reabsorption or other mechanism)
Transport vers la fente synaptique
NA: éveil, DA: récompense et motivation

Q

inhibiteurs de la monoamine oxydase (IMAO-A)

- inhibiteurs sélectifs de la recapture de la sérotonine (ISRS)

These drugs take a few minutes to act…but their benefit is not seen until 3 weeks?? Why?

A

their effects seemes to be connected to plasticty. specifically the “healing” of circuts that caused the depression
