Domperidone as a Treatment for Dopamine Agonist-Induced Peripheral Edema in Patients With Parkinson's Disease

2014-08-27 03:45:36 | BioPortfolio


The dopamine agonists, pramipexole (Mirapex) and ropinirole (Requip), are drugs that are used to treat symptoms of Parkinson's disease. However, these drugs can induce bothersome leg swelling or edema in about 20 percent of patients. The cause of this edema is unknown but may be secondary to stimulation of peripheral dopamine receptors in the kidney or blood vessels. We hypothesise that a peripherally acting dopamine receptor antagonist, will reduce edema in PD patients. This study will assess the effect of the peripheral acting dopamine D2 receptor antagonist, domperidone as a potential treatment for dopamine agonist-induced leg swelling.


The study is a phase II, randomised double-blind, placebo-controlled, cross-over trial. There are four periods: recruitment and randomisation; treatment period one (4 weeks); washout (1 week); and finally treatment period two (4 weeks). Patients will be randomly assigned domperidone 20 mg tid in treatment period one followed by placebo tid in treatment period two, or placebo tid in treatment period one followed by domperidone 20 mg tid in treatment period two.

Medical and Biotech [MESH] Definitions

Proteins associated with sporadic or familial cases of PARKINSON DISEASE.

A selective, irreversible inhibitor of Type B monoamine oxidase. It is used in newly diagnosed patients with Parkinson's disease. It may slow progression of the clinical disease and delay the requirement for levodopa therapy. It also may be given with levodopa upon onset of disability. (From AMA Drug Evaluations Annual, 1994, p385) The compound without isomeric designation is Deprenyl.

A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)

A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.

Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
