Do any beta blockers act on Central Nervous System? Labetalol, Propranalol? What about Alpha-1 blockers?

Do any beta blockers act on Central Nervous System?  Labetalol, Propranalol? What about Alpha-1 blockers?

Yes, most of them: Beta blockers are either water soluble or lipid soluble. The latter cross the blood-brain barrier and act on the CNS (central nervous system). Atenelol and Naldolol are 2 water soluble ones that do not readily cross into the brain. Alpha blockers generally do act on the CNS, and the 2 most common side effects are hypotension and dizziness. ...Read more

Does Zoloft (sertraline) calm down the nervous system ?

Does Zoloft (sertraline) calm down the nervous system ?

Sertraline mechanism: Zoloft (sertraline) does not calm the entire nervous system, it specifically works a part that uses serotonin. It is a serotonin re-uptake inhibitor. This is meant to change levels of a neurotransmitter involved in the feelings of depression and anxiety. It does not affect many other neurotransmitters in the nervous system, such as dopamine, glutamate, etc. ...Read more

Do selective adeno-adenergic blockers (prazosin, terazosin, doxazosin, trimazosin) protect  from acute cocaine-induced vasoconstrictive damage?

Do selective adeno-adenergic blockers (prazosin, terazosin, doxazosin, trimazosin) protect  from acute cocaine-induced vasoconstrictive damage?

Some: Cocaine causes it's effect by preventing the reuptake of monamine (epinephrine, etc) and causes these neurotransmitters to continue exciting the a1 receptor. The meds listed block alpha-1 receptors, so theoretically will blunt the effects of Cocaine on some vessels, but focus mostly (esp. Tamsulosin) on a specific sub-type (alpha-1a) that is mostly in the bladder, not in the vessels. ...Read more

Can you tell me examples for central nervous system, peripheral nervous system, somatic nervous system?

Can you tell me examples for central nervous system, peripheral nervous system, somatic nervous system?

OK: Central nervous system - brain & spinal cord Peripheral nervous system - all the nerves that come out from the brain and spinal cord. Within the peripheral nervous system you have 'somatic' and 'visceral' nervous systems. Somatic refers to muscle, skeleton, skin. Visceral refers to internal organs. In a nutshell! ...Read more

Why do the cholinergic agonist drugs act on the parasympathetic (but not the sympathetic) nervous system?

Cholinergic meds: This is a complicated question and cannot be properly answered in 400 spaces. See wikipedia. Basically the receptors for parasympathetic system do not recognize the cholinergic molecules. ...Read more

Only noradrenergic antidepressant works for me, does inderal (propranolol) acts negative on noradrenergic effects of antidepressant ?At vasomotor centers.Regards.

Only noradrenergic antidepressant works for me, does inderal (propranolol) acts negative on noradrenergic effects of antidepressant ?At vasomotor centers.Regards.

Venlafaxine: It's not the vasomotor centers that are important in antidepressant response; it's the neuron synapses in the brain. Effexor (venlafaxine) inhibits reuptake of both serotonin and ne. Inderal can suppress some of the physical symptoms of anxiety (rapid heart rate, sweaty palms, tremulousness, etc). Some on chronic (not intermittent or "prn") Inderal have had more depression. Not everyone. You should be okay. ...Read more

Can overuse of a centrally acting stimulant like Pseudoephedrine trigger apermanent change in adrenergic receptors...hypersensitive sympathetic systm?

Can overuse of a centrally acting stimulant like Pseudoephedrine trigger apermanent change in adrenergic receptors...hypersensitive sympathetic systm?

Not likely: Adrenergic drugs are used to manage sympathetically maintained pain. They act either presynaptically on the neuron or postsynaptically on receptors located on the effector organ. They may affect receptors that are stimulated by norepinephrine (NE) or epinephrine, or interrupt the release of NE from noradrenergic neurons. ...Read more

What antidepressant medications selectively block neurotransmitters?

Most newer ones: Most of the newer antidepressant medications affect specific neurotransmitters. Each does it slightly differently, accounting for the different response rates amongst them. The SSRI's primarily increase serotonin, the SNRI's both serotonin and norepinephrine, and buproprion mostly norepinephrine alone, and Brintellix affects many of them in different ways and in different places in the brain. ...Read more

Does drugs attack the central nervous system?

Does drugs attack the central nervous system?

Which drugs? Attack?: Many drugs act on the brain, some because they are meant to, others as side effects. Very few drugs damage the cns. The ones that are known to cause permanent changes are alcohol and stimulants like cocaine/crack and methamphetamine when used for long periods. Tolerance to opioids and benzodiazepines takes a year or so to disappear completely, but the effects are thengone. ...Read more
