Desmopressin Vs Vasopressin
ADH (vasopressin): My apologies but I have spent some time on line and could not find the answer to your interesting question. You might go the Medical University's library and see what you can find. The librarian will help you. If you do find out please try and let me know. ...Read more
Dx'd w/partial idiopathic central diabetes insipidus 20yrs ago by H20deprivation test. Put on DDAVP (desmopressin). No longer needed DDAVP (desmopressin) after 2 yrs.Sx better.Why?
Central DI: Hard to answer. It was called "idiopathic", meaning no clear cause. In a 13 yr old, the causes could include a tumor, certain medications, trauma/surgery, meningitis, etc. It is possible that something happened back then but then resolved. Is it possible that you now still have partial DI? Under usual conditions, don't need DDAVP, (desmopressin) but under water stress you may. See your Endocrinologist. ...Read more

ADH (vasopressin) & Oxytocin: Both are produced in hypothalamus and stored in the posterior pituitary gland. ...Read more
Stimulaton test: Patients with type 1 VWD less vw factor than normal people. However, they store vwf normally in the cells that line their blood vessels. This can be released into the blood by certain drugs; one of these is ddavp (desmopressin). In a DDAVP (desmopressin) challenge the vwf level is measured, a dose of DDAVP (desmopressin) is given, and the level measured again to see if it goes up significantly. If so, DDAVP (desmopressin) can be used to control bleeding. ...Read more
Doc wants 2 do anti diuretic hormone (adh) test for diabetes insipidus. Thought u had 2 b deprived of fluid during ADH (vasopressin) test...Or is that necessary?
Yes: There is a test called water deprivation test which is the gold standard for testing but pt's have to be monitored closely. Therefore, sometimes we may give a trial of ADH (vasopressin) as a pill to see if the symptoms resolve after it has been verified pt's are making >3l of urine a day. ...Read more
Thioridazine: Wow....you sound like one of my profs in training who would just love giving us the biggest pimp questions the next morning knowing that none of us were awake and none of us believed we'd get called to have to answer any of these really hard questions. The only one I can think of which is virtually entirely NON-selective is THIORIDAZINE. Everything else has some selectivity. ...Read more
Pituitary: Hi. ADH (vasopressin) & oxytocin are made in neurons in the hypothalamus and travel down the axons in the pituitary stalk to the posterior pituitary where they are stored until they're released. They're referred to as "posterior pituitary hormones", but they're made in the hypothalamus and only stored and released from the posterior pituitary. ...Read more
Signal-response.: Adh, or vasopressin, is a hormone released by the posterior pituitary gland when the body wishes to conserve water. Aquaporin 2 (aqp2) channels in the kidney are activated by adh, which reabsorb water back into the bloodstream, concentrating and decreasing the volume of urine. Mutations in aqp2 can lead to diabetes insipidus, where large volumes of urine are released. ...Read more

Many causes: Poor ADH (vasopressin) production is an extremely rare cause for frequent urination at night. One of the most common causes is fluid retention during the day. If you have varicose veins or other causes for swelling of the legs, once you lie down at night, the fluid comes out of the legs and into your bladder, making you urinate more. If you drink a lot in the evening, you will urinate more at night. ...Read more
Nocturia: Hi. How many times do you get up to pee on an average night? Diabetes insipidus (poor ADH (vasopressin) production or function) is a very uncommon cause of nocturia. The most common is drinking a lot in the evening. Diabetes mellitus is also a common cause of nocturia. Congestive heart failure or any cause of lower extremity edema where the kidneys still work will cause nocturia. ...Read more
Would a natural diuretic (e.g. dandelion root) be effective for SIADH (syndrome of inappropriate antidiuretic hormone)?
Dandelion root: The simple answer is NO! Please go online to "WebMD" and look for dandelion root. You will learn a lot and make up your own mind to decide if it is a good idea or not. Don't forget costs. ...Read more
