The trial was an experimental two-centers, randomized, double-blind, two-sequence, non-inferiority cross-over study. Screened subjects already treated with Levodopa/Benserazide (LDB) (Mad...
The purpose of this study was to investigate the effect on the "wearing-off" phenomenon of 3 different doses of nebicapone (NEB 50 mg, 100 mg and 150 mg), compared with entacapone and plac...
The purpose of this study is to investigate the tolerability, pharmacokinetic profile of BIA 3-202 and its metabolites, and the pharmacokinetic and pharmacodynamic interaction between 4 di...
This is a Phase IIa randomized, double-blind, placebo controlled, single ascending dose (SAD) study to compare the safety, tolerability and PK/pharmacodynamic of intranasal L-dopa followin...
To investigate the effect of four single oral doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) on levodopa pharmacokinetics when administered in combination with a single-dose of contr...
Levodopa is the main treatment for symptoms of Parkinson's disease. Determining whether levodopa also has a disease-modifying effect could provide guidance as to when in the course of the disease the ...
Human gut microbiota senses its environment and responds by releasing metabolites, some of which are key regulators of human health and disease. In this study, we characterize gut-associated bacteria ...
Dosing schedules for oral levodopa in advanced stages of Parkinson's disease (PD) require careful tailoring to fit the needs of each patient. This study proposes a dosing algorithm for oral administra...
Weight loss (WL) is a frequent yet under-recognized complication of levodopa/carbidopa intestinal gel (LCIG) infusion, as well as a milestone of Parkinson disease (PD) disability progression. The comp...
In Parkinson's disease, dyskinesias result from disease progression and chronic levodopa therapy. Using Unified Dyskinesia Rating Scale (UDysRS) data pooled from two pivotal trials of ADS-5102 (amanta...
An inhibitor of DOPA DECARBOXYLASE, preventing conversion of LEVODOPA to dopamine. It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA. It has no antiparkinson actions by itself.
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.
An inhibitor of DOPA DECARBOXYLASE that does not enter the central nervous system. It is often given with LEVODOPA in the treatment of parkinsonism to prevent the conversion of levodopa to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system and reducing the required dose. It has no antiparkinson actions when given alone.
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
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)
