Some Mechanisms of Drug Action

Drug increases the synthesis of NT molecules by serving as precursor

Drug blocks the synthesis of NT molecules by destroying synthesizing enzymes

Drug causes the NT molecules to leak from the synaptic vesicles to cytoplasm where degrading enzymes destroy NT molecules

Drug increases the number of NT molecules by destroying degrading enzymes

Drug increases the release of NT molecules from terminal buttons

Drug blocks the release of the NT molecules from terminal buttons

Drug binds to postsynaptic receptors and activates them

Drug activates autoreceptors and inhibits NT release

Drug binds to the postsynaptic receptors and occupy them without activating them (blocking the receptor)

Drug blocks the deactivation of NT molecules by destroying degrading enzymes

Drug blocks the presynaptic transporter blocking reuptake
