What will be the effect of cholinergic agonist on the pyloric sphincter?
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.
How does ectasy mimic natural neurotransmitters?
Ectasy (MDMA) is a derivative amphetamine. It is similar to the natural drug ephedrine and may be a alpha/beta agonist (mimics both epinephrine and noradrenaline). What is more clear is that a secondary effect of the drug is an increased release of dopamine and serotinin in the central nervous system (see NIH article).
Is epinephrine an adrenergic agonist?
adrenalin is an agonist
Is L-dopa an agonist or antagonist for dopamine?
agonist- Facilitstes synthesis
What are the Antagonist in pharmacology?
Drug having defenite affinity to bind the receptor but, does not activate it (no intracelluler changes occur after drug receptor complex is formed), thus the receptor in other word is being blocked, and the the respective pharmacological response which was supposed to be occured by the binding of the agonist, does not occur.
The drug effect in which one drug neutralizes another drug is?
Inverse Agonist.
The effect of a drug that is an agonist is to?
An agonist binds to a receptor and stimulates it (turns it on). An antagonist binds to a receptor and blocks it from being activated by other molecules (turns it off).
Is Pheniramine an agonist or partialagonist or antagonist?
Pheniramine is a histamine drug which have anticholinergic action but its effect is agonistic or antagonist or partialagonist. Pheniramine is a histamine drug which have anticholinergic action but its effect is agonistic or antagonist or partialagonist.
Is buprenorphine a drug?
Yes. Buprenorphine is a medication/drug which has mixed opioid agonist-antagonist properties. (It is a major component of Suboxone.)
Muscimol is a direct agonist for the gabaa receptor this means that muscimol binds to which spot on the receptor as gaba and what that is has effect as gaba?
Muscimol is a GABA A agonist effet psychotomimetic
What will be the effect of cholinergic agonist on the pyloric sphincter?
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.
What is a drug that blocks the release of neurotransmitters?
An example of a drug that blocks release of a neurotransmitter is botulinum toxin (Ach) and atropine.
What positive modulation?
Enhancing the action of an agonist without having an individual effect itself.
What class of drugs is suboxone?
Suboxone is an opiate class drug/medication.
What is an opiate agonist?
An opiate agonist gives the user the same feeling as would be experienced by an endorphin, which is a natural compound. The receptors in the brain that feel effects from opiates receive the opiate agonist and feel an opioid effect, even though one isn't really happening.
Does naltrezone show up on a drug test?
I believe you mean naltrexone. In the world of opiates, there are three major categories. 1. Agonists 2. Antagonists 3. Agonist/Antogonists An agonist is a medication, for example - Morphine, which attaches to an opiate receptor and results in pain relief, along with other actions, such as sedation, euphoria, etc. depending upon which type of opiate receptor it attaches to. An Antogonist is a medication like naltrexone, which will reverse the effect of a medication like morphine by competing for the receptor with morphine, and not allowing the agonist to work, reversing the effect of the morphine. An agonist/Antogonist is a medication like nalbuphine (Nubain) which will act differently, depending on the circumstances. If an agonist (morphine) is present in the system already, this class of medication will act like an Antogonist, thus reversing the effects of the morphine. If no agonist is present, then it will have an agonist effect and cause pain relief, etc. To answer your question, I believe it would depend upon the specific drug test, and how sensitive the particular test is for the various classes of opiates. Most tests that I am aware of check for many different opiates specifically, such as morphine, hydrocodone, oxycodone, codeine, heroin, etc. I am unaware of any testing specifically for naltrexone, but it certainly could be tested for, depending upon why the particular test is being done and the clinical circumstances.
