WebDrugs can affect postsynaptic receptors by binding to them directly, but they can also bind to presynaptic receptors to influence neurotransmission by altering how much transmitter is released. We will look at both direct and indirect methods, starting with the former. Presynaptic receptors modulate the production and/or release of the transmitter.

WebHow do drugs inhibit synaptic transmission antagonists? Drugs can influence the synapse in two ways: they can either act as agonists or antagonists. Agonists are substances that bind to synaptic receptors and increase the effect of the neurotransmitter. Antagonists also bind to synaptic receptors but they decrease the effect of the neurotransmitter
