Ergoline derived agonists comprise the first generation; more widely used today are the non-ergoline derived agents. Ergoline derived agonists are generally less selective and tend to show interactions with receptors other than dopamine receptors, which can cause more side effects.
Common side effects include sleepiness, vomiting, and dizziness. [4] Serious side effects may include pathological gambling, low blood pressure with standing and hallucinations. [3] [4] Use in pregnancy and breastfeeding is of unclear safety. [5] It is a dopamine agonist and works by triggering dopamine D 2 receptors. [4]
Side effects of levodopa include nausea, the wearing-off phenomenon, dopamine dysregulation syndrome, and levodopa-induced dyskinesia, among others. [3] The drug is a centrally permeable monoamine precursor and prodrug of dopamine and hence acts as a dopamine receptor agonist. [3] Chemically, levodopa is an amino acid, a phenethylamine, and a ...
More serious side effects include depression, low blood pressure with standing, sudden onset of sleepiness, psychosis, and increased risk-taking behavior. [6] [10] Carbidopa prevents the breakdown of levodopa outside the brain. [10] In the brain, levodopa is broken down into dopamine, its active form. [10]
Nausea and vomiting are common side effects when first beginning therapy with apomorphine; [18] antiemetics such as trimethobenzamide or domperidone, dopamine antagonists, [19] are often used while first starting apomorphine. Around 50% of people grow tolerant enough to apomorphine's emetic effects that they can discontinue the antiemetic.
One of the main reasons Ozempic and other GLP-1 agonist medications are so effective is because they target your brain, not just your stomach. While this bodes well for weight loss, some users are ...
Certain medications such as dopamine agonists are not used, as they may worsen psychotic symptoms to those taking neuroleptic drugs. If the EPS are induced by an antipsychotic , EPS may be reduced by decreasing the dose of the antipsychotic or by switching from a typical antipsychotic to an (or to a different) atypical antipsychotic , such as ...
Trade names include Sinemet, Pharmacopa, Atamet, and Stalevo. As a drug, it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia. l-DOPA has a counterpart with opposite chirality, d-DOPA. As is true for many molecules, the human body produces only one of these isomers (the l-DOPA form).
