Dopamine Agonists
Dopamine agonists (DA) have been used to treat symptoms of Parkinson’s disease (PD) since the late 1970s (1). These agents were initially introduced to supplement the beneficial effect and possibly reduce the incidence of longterm complications of levodopa. In the last 30 years, methodical investigations of DA have demonstrated therapeutic benefit in all stages of PD both in combination with le...
متن کاملNeuroprotection by dopamine agonists.
Research on Parkinson's disease has led to new hypotheses concerning the mechanisms of neurodegeneration and to the development of neuroprotective agents. Recent findings of impaired mitochondrial function, altered iron metabolism and increased lipid peroxidation in the substantia nigra of parkinsonian patients emphasize the significance of oxidative stress and free radical formation in the pat...
متن کاملDopamine Agonists and Pathologic Behaviors
The dopamine agonists ropinirole and pramipexole exhibit highly specific affinity for the cerebral dopamine D3 receptor. Use of these medications in Parkinson's disease has been complicated by the emergence of pathologic behavioral patterns such as hypersexuality, pathologic gambling, excessive hobbying, and other circumscribed obsessive-compulsive disorders of impulse control in people having ...
متن کاملProlactinomas.
Identifying the correct cause of hyperprolactinemia is crucial for treatment. Prolactinoma is the most common pathologic cause of hyperprolactinemia. Dopamine agonists are efficacious in about 80% to 90% of patients with prolactinoma, leading to reduction of serum prolactin levels and tumor dimensions. Neurosurgery, mainly by the transsphenoidal route, is indicated in cases of intolerant and re...
متن کاملDopamine-deficient mice are hypersensitive to dopamine receptor agonists.
Dopamine-deficient (DA-/-) mice were created by targeted inactivation of the tyrosine hydroxylase gene in dopaminergic neurons. The locomotor activity response of these mutants to dopamine D1 or D2 receptor agonists and l-3,4-dihydroxyphenylalanine (l-DOPA) was 3- to 13-fold greater than the response elicited from wild-type mice. The enhanced sensitivity of DA-/- mice to agonists was independen...
