Thibodeau, Kevin T. Patton 1,505 solutions What is an antagonist of a neurotransmitter?An antagonist is a compound that has the opposite effect of an agonist. It decreases the activation of a synaptic receptor by binding and blocking neurotransmitters from binding or by decreasing the amount of time neurotransmitters are in the synaptic cleft. These actions can be achieved via multiple mechanisms.
What drug blocks the action of a neurotransmitter?Antagonist drugs block a chemical response at a neurotransmitter receptor. Opiate painkillers, including morphine and codeine, are examples of agonist drugs that bind to and activate neurotransmitter receptors, producing feelings of pain relief.
What drugs block the reabsorption of neurotransmitters?SSRIs block the reabsorption (reuptake) of serotonin into neurons. This makes more serotonin available to improve transmission of messages between neurons. SSRIs are called selective because they mainly affect serotonin, not other neurotransmitters.
Which neurotransmitters are agonist and antagonist?Epinephrine (adrenalin) is primarily present in the autonomic nervous system. It has similar functions as norepinephrine and both neurotransmitters bind alpha- and beta-adrenergic receptors.
