Animal studies indicate that beta(2)-adrenergic receptor agonists enhance transport of levodopa across the blood-brain barrier. Preliminary studies showed improved response to levodopa in patients with Parkinson disease (PD) who were given albuterol as adjunctive therapy. Beta(2)-adrenergic agonists
BACKGROUND
Motor response fluctuations and dyskinesias compromise long-term levodopa therapy in Parkinson's disease. Variations in plasma levodopa levels contribute to adverse reactions associated with chronic therapy. Therefore, sustained-release levodopa preparations may be associated with less
This open-label phase I trial assessed potential pharmacokinetic interactions between oral levodopa/carbidopa and transdermal rotigotine treatment at steady state. Twenty-four participants with idiopathic restless legs syndrome (12 per group) received levodopa/carbidopa (100 mg/25 mg bid) and
OBJECTIVE
To investigate the safety, tolerability, pharmacokinetic, and pharmacodynamic properties of the dopamine transporter antagonist brasofensine (BMS-204756) in patients with Parkinson's disease receiving levodopa/carbidopa treatment.
METHODS
A 4-period crossover study was performed in 8 men
OBJECTIVE
To investigate the effect of sarizotan on the pharmacokinetics of levodopa in fixed combination with carbidopa or benserazide.
METHODS
In this open-label, randomized, crossover study, healthy male subjects (n=16) received levodopa 100 mg t.i.d. over two 5-day periods, alone or in
OBJECTIVE
IPX066 is an extended release carbidopa/levodopa formulation designed to rapidly attain and maintain therapeutic plasma concentrations for a prolonged duration, allowing dosing intervals of approximately 6 h. The objective was to assess the efficacy, safety, and impact on quality of life
BACKGROUND
Despite the known benefit of levodopa in reducing the symptoms of Parkinson's disease, concern has been expressed that its use might hasten neurodegeneration. This study assessed the effect of levodopa on the rate of progression of Parkinson's disease.
METHODS
In this randomized,
During a long-term double-blind study, which began February 1985, we have treated 16 patients with Morbus Parkinson or Parkinson's syndrome with deprenyl or identically appearing placebo tablets. The aim of the study is to ascertain whether a reduction of other antiparkinsonian medication,
BACKGROUND
Manganese is known to cause a parkinsonian syndrome similar clinically to Parkinson disease (PD). L-Dopa responsiveness is a hallmark of PD; however, L-dopa's effect on manganese-induced parkinsonism is not well defined.
OBJECTIVE
To access the efficacy and safety of L-dopa therapy in a
The objective of this study was to establish the maximum tolerated dose of the low affinity non-competitive N-methyl-D-aspartate receptor antagonist remacemide in patients who have Parkinson's disease with response fluctuations or dyskinesias, or both. A total of 33 patients were randomly assigned
It was one of the great pleasures to have fulfilled my long-held dream in 1986, newly opened the Kitasato University East Hospital (KUEH). In 1965, I served at chronic ward of Baltimore City Hospitals as a resident of neurology, where most of the patients were relaxed and enjoyed their hospital
BACKGROUND
Melioidosis is a rare condition, endemic to northern Australia and south-east Asia, caused by an infection from the bacteria Burkholderia pseudomallei. The largest epidemiological review to date describes 540 cases of melioidosis seen at Darwin Hospital, in northern Australia, over
Rotigotine transdermal patch (Neupro(®)) [referred to here as rotigotine] is a non-ergolinic dopamine agonist that is available in the EU as monotherapy for the treatment of early Parkinson's disease and as combination therapy with levodopa throughout the course of the disease. Daily application of
The number of dopamine agonists (DA) used in Parkinson's disease (PD) is gradually increasing. They have different affinity to the dopamine receptor subtypes. When choosing one of these drugs one should consider its efficacy in monotherapy in early phase and in combined therapy with levodopa in
Quetiapine is an atypical antipsychotic with clozapine-like pharmacology but without associated agranulocytosis. We report our complete experience with quetiapine for the treatment of drug-induced psychosis (DIP) in Parkinson's disease (PD). Thirty-five patients with PD and DIP aged 75 years (range,
