Webb28 aug. 2024 · 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. Therefore, if a neurotransmitter is inhibitory, an agonist will increase its inhibitory characteristics and an antagonist will decrease it. WebbIC 50 is a quantitative measure that indicates how much of a particular inhibitory substance (e.g. drug) is needed to inhibit, in vitro, a given biological process or biological component by 50%.
