What is the relationship between drugs and the transmission of neurotransmitters?
Drugs can impact neurotransmitter transmission by either mimicking or blocking the action of neurotransmitters at the synapse. For example, drugs like cocaine can block the reuptake of neurotransmitters like dopamine, leading to increased neurotransmitter levels in the synapse. This alteration in neurotransmitter levels can result in changes in brain function and behavior.
How do drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
What will happen if lack of acetylcolinesterase in the synaptic cleft?
Neurotransmitters would continue to bind and rebind with the postsynaptic receptors, which would continue induction of a signal in the postsynaptic neurons, which would repropagate the initial signal. The case in drugs that block reuptake transporters (such as in serotonin reuptake inhibitor and norepinephrine reuptake inhibitor antidepressants, and dopamine reuptake inhibition found with cocaine and methylphenidate). This is also seen in cases where drugs block the breakdown of neurotransmitters at the synapse: - monoamine oxidase inhibitors (MAOIs) - Nardil, Parnate, selegiline - which prevent the breakdown of serotonin, norepinephrine, and dopamine - acetylcholinesterase inhibitors (AChE inhibitors) - organophosphase pesticides, nerve gas, racetams
Do antagonists increase the reuptake of neurotransmitters as they cross the synaptic gap that separates neurons?
Antagonists do not typically increase the reuptake of neurotransmitters. Instead, antagonists are substances that block or inhibit the action of neurotransmitters at their receptors, preventing the intended signaling effects. Reuptake refers to the process by which neurotransmitters are reabsorbed by the presynaptic neuron after crossing the synaptic gap, and this process is primarily influenced by transport proteins rather than antagonists.
How-to block the scent of drugs?
Burn an incense stick.
What are agonist and antagonists?
antagonist drugs are drugs that block transmitters in the brain that cause illnesses. Hope this helped!
What does reuptake inhibitor mean?
to understand reuptake you have to understand the basic firing of neurotransmitters: a neurotransmitter is realeased from one neuron and floats accross the synapsde or gap to activate the receiving neurons receptor site. after the other neuron has received the information from the neurotransmitter it unbinds and floats back into its original neuron and goes back into the storage tanks or vessicles. reuptake inhibtors block this process thus leaving more of the particular neurotransmitter in the synapse. different neurotrasnmitters have different effects. an SSRI or seretonin reuptake inhibitor is used for depression. cocaine is a dopamine reuptake inhibitor just like Ritalin this leaves more dopamine in the brain which causes awakefullness etc....
What drugs do to your head?
drugs block the nerve impulses in the brain ---- Answer: It depends on the drug, some drugs "makes your brain sleep" while others do permenant damage.
Why are drug companies worldwide in a race to develope drugs that block chemokines?

What type of drugs block the effects of certain neurotransmitters on the brain?

Is Effexor an anti-cholinergic drug?
No, Effexor (venlafaxine) is not classified as an anticholinergic drug. It is a serotonin-norepinephrine reuptake inhibitor (SNRI) primarily used to treat depression and anxiety disorders. Anticholinergic drugs block the action of acetylcholine, while Effexor works by increasing the levels of serotonin and norepinephrine in the brain. However, some side effects of Effexor may overlap with those of anticholinergic medications.
How could the drugs effect the nervous system?
nerves drugs increase or decrease or block chemical neurotransmitters effects according by physician diagnose
