do we need to know what these are? They aren't on the study design but they came up on the 2017 exam so I'm confused

sammmmm —

if they were on a past exam then that's kinda an indication that you should know what they are

tyson4920 —

Then what are they?

sammmmm —

agonsts are drugs that mimick the effects of a neurotransmitter by binding to the receptor site on the post-synaptic neuron and activating it. Antagonists are drugs that mimick the effects of a neurotransmitter by binding to the receptor site on the post-synaptic neuron and blocking it

agonists are used when someone has low levels of a neurotransmitter and antagonists are used when someone has too much
