Doctor insights on:
Hypersecretion Of Epinephrine And Norepinephrine
Yes: The caffeine in coffee blocks Adenosine receptors, which when activated make you tired and sleepy. This blockade also affects all major neurotransmitters, such as dopamine, acetylcholine, serotonin -- and in high doses, norepinephrine too. Dopamine effects are not in the exact same regions of the brain that other addictive substances affect, though. ...Read moreSee 1 more doctor answer
Vasopressin,: also known as antidiuretic hormone/ADH, is a "pituitary" hormone which acts to retain water and constrict blood vessels. It increases water reabsorption in the kidney's collecting ducts. Decreased release due to alcohol intoxication or tumor leads to increased blood sodium/excessive urination/thirst. Excess vasopressin leads to low sodium. A number of problems cause inappropriate ADH-tumors, drugs ...Read moreSee 1 more doctor answer
Catecholamines: Behavior is much more complex than neurotransmitter levels alone. But norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus. When released, ne triggers the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more. ...Read more
What are the effects of dopamine on cortisol and other stress hormones? Where is dopamine released from/created at?
Dopamine cortisol: D will increase cortisol when given IV. I would do a Wikipedia search for more details. Not enough room here and they have good pictures as well. ...Read more
Negative emotions: Strongly impact our biochemistry in general. They can eventually burn out our adrenal glands. For a lab analysis of neurotransmitters via urine your doc can use neuroscience lab, who specialize in this, along with supplemental formulas to balance things naurally. Peace and good health. ...Read more
Wellbutrin (bupropion): Wellbutrin (bupropion) acts by enhancing the levels of serotonin, dopamine, and norepinephrine at the site of each neurotransmitter. For this reason, it's an excellent medication choice for depression and executive functioning, such as conditions with attention and concentration impairments. However, due to its actions upon dopamine, it is relatively contraindicated in psychotic conditions. ...Read moreSee 1 more doctor answer
Receptors: These three medications are used to support the heart and cardiovascular system ie. blood pressure and heart rate. They are known as sympathomimetics and have a similar response to what you would think of as adrenaline. Each has variable effect on either heart rate, heart function (in terms of strength of 'squeeze') and on blood vessels which would translate to higher blood pressure. ...Read more
I was wondering what are the differences of levophed, (norepinephrine) dopamine and dobutamine in terms of their action?
You Asked for It----: Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system. Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. ...Read more
What are norepinephrine and epinephrine's effects on heart rate, blood pressure, vasoconstriction, sensitivity to pain, and heat production.
EPI: It increases heart rate and blood pressure (sometimes dangerously). It causes vasoconstriction. Variable effect on pain but generally increases sensitivity and because it ramps up your metabolism it increases heat production. Follow your docs instructions very carefully and don't freelance. ...Read more
Whether heomopathic treatment set right the imbalance of neurochemicals of serotonin and dopamine depression?
No studies: There are no studies that i know of which document serotonin or Dopamine levels during homeopathic treatment. The 2 paradigms of health and illness are very different. Other issue is that no one has proven that neurochemical imbalance directly causes depression, either. It would be an interesting study, but you'd need many well trained homeopaths, & patients willing to have lp's with treatment. ...Read more
Can Adderall (dextroamphetamine and racemic amphetamine) effect the levels of hormones produced by the thyroid?
Adderall (dextroamphetamine and racemic amphetamine) and thyroid: Adderall (dextroamphetamine and racemic amphetamine) will not increase the blood levels of thyroid hormone. But the stimulatory effects of Adderall (dextroamphetamine and racemic amphetamine) are similar to the stimulatory effects of too much thyroid. If your thyroid is normal, it is not an issue. But if you suffer from hyperthyroidism (eg. Graves disease, too much medication), then the combined effects of the disease and the Adderall (dextroamphetamine and racemic amphetamine) can be dangerous to your heart. ...Read more
Increase BP: These hormones will all tend to increase blood pressure, with Epinephrine having the most marked effect and erythropoetin the smallest. The effects will be more marked if baseline BP is elevated, or if on a high salt diet. Aldosterone also tends to lower potassium which can be a clue that the body is producing too much. ...Read more
Alters physiology: These are very simple answers to a complex question. Levophed (norepinephrine) increases blood pressure; Dopamine increases heart rate, blood pressure and cardiac function (contractility); Dobutamine increases cardiac contractility and heart rate. ...Read moreSee 1 more doctor answer
What hormone inhibits the secretion of adh (vasopressin)? And what situations override the release of this inhibiting hormone?
ADH (vasopressin) secretion: ADH (vasopressin) is mostly controlled by plasma osmolality and plasma volume. Diabetes insipidus occurs when ADH (vasopressin) is not secreted (head trauma, pituitary tumor) or when the kidney does not respond to it (nephrogenic di). Ethanol inhibits adh, (vasopressin) as does atrial naturetic protein, but these are lesser influences than osmolality and volume. ...Read more
What are the differences in levels of pns stimulation among commonly prescribed amphetamines, specifically dextroamphetamine and methylphenidate?
Hypo and Hyper: Both items are not good. Please go online and read the many articles for non-doctors that will help you understand the above. Hypo is too low. Hyper is too high. ...Read more
Is Adderall (dextroamphetamine and racemic amphetamine) tolerance caused by an influx of ca2+ and does mg antagonize the rapid influx of ca2+ thus minimizing tolerance?
Using knowledge of the dopaminergic neurone, how might one increase or decrease the release of dopamine?
Natural High : There are many ways once can try to increase brain Dopamine levels. But what ever you do, do not do it with drugs. The high is short and "fun"; the fall is miserable and and long. Some supplements can help, but discuss with your doctor before flushing your dollars down the drain. If natural measures fail, there are effective prescription medications which can help with your Dopamine concern. ...Read more
