Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small. [ 2 ]
Dopamine was first synthesized in a laboratory in 1910 by George Barger and James Ewens in England. [8] It is on the World Health Organization's List of Essential Medicines. [9] In human physiology dopamine is a neurotransmitter as well as a hormone. [10]
Cabergoline, sold under the brand name Dostinex among others, is a dopaminergic medication used in the treatment of high prolactin levels, prolactinomas, Parkinson's disease, and for other indications. [2] It is taken by mouth. Cabergoline is an ergot derivative and a potent dopamine D 2 receptor agonist. [3]
Ropinirole acts as a D 2, D 3, and D 4 dopamine receptor agonist with highest affinity for D 3, which are mostly found in the limbic areas. [13] It is weakly active at the 5-HT 2 , and α 2 receptors and is said to have virtually no affinity for the 5-HT 1 , GABA , mAChRs , α 1 -, and β-adrenoreceptors . [ 14 ]
DaT Scan (DaT scan or Dopamine Transporter Scan) commonly refers to a diagnostic method, based on SPECT imaging, to investigate if there is a loss of dopaminergic neurons in striatum. The term may also refer to a brand name of Ioflupane (123I) tracer used for the study.
In accordance with this, drugs that affect 5-HT-containing cells or 5-HT receptors are effective treatments for numerous indications, including depression, anxiety, obesity, nausea, and migraine. Because serotonin and the related hormone melatonin are involved in promoting sleep, they counterbalance the wake-promoting action of increased ...
The skeletal structure of norepinephrine The skeletal structure of dopamine. A norepinephrine–dopamine reuptake inhibitor (NDRI) is a drug used for the treatment of clinical depression, attention deficit hyperactivity disorder (ADHD), narcolepsy, and the management of Parkinson's disease.
Dopamine beta (β)-hydroxylase deficiency is a human medical condition involving inadequate dopamine beta-hydroxylase. It is characterized by increased amounts of serum dopamine and the absence of norepinephrine (NE) and epinephrine. Dopamine is released, as a false neurotransmitter, in place of norepinephrine (aka noradrenaline and ...
