The primary objective is to examine whether a memory impairment as a result of biperiden treatment (cholinergic M1 antagonist) will be increased by acute tryptophan depletion (ATD, a drink that decreases serotonin synthesis). In other words, we will…
The primary objective is to examine whether a memory impairment as a result of biperiden treatment (cholinergic M1 antagonist) can be reversed by rivastigmine (a cholinesterase inhibitor). Secondary, we will assess the effects of biperiden and…
• To determine the profile of CNS effects at several time points after 2 mg and 4 mg biperiden in comparison to placebo in healthy elderly subjects.• To investigate the safety and tolerability of biperiden in healthy elderly subjects.• To determine…
We will examine the cognitive performance of healthy young participants at different time points after a single administration of biperiden. The behavioural outcomes and electrophysiological correlates will be linked with the serum levels of…
Our objective is to investigate the value of a HVIGI in chronic midportion Achilles tendinopathy, using a dubbel-blind, placebo-controlled, randomised clinical trial. We expect that this study design gives us the opportunity to provide solid advise…
The effect of correction of metabolic acidosis in chronic kidney disease on intrarenal RAS activity.
Primary Objective: - To study if sodiumbicarbonate therapy in patients with metabolic acidosis due to chronic kidney disease diminishes intrarenal RAS activity (without affecting the systemic RAS).Secondary Objective(s): - To study if…
This is a medical-scientific research study. The purpose of the study is to investigate the effect of multiple doses of the study compound BIA 28-6156 on the pharmacokinetics of the drugs levodopa-carbidopa (Group 1) and levodopa-benserazide (Group…
- Characterization of the CNS PD profile of IV administered biperiden- Characterization of the pharmacokinetic profile of IV administered biperiden- To confirm the plasma concentration-effect relationship of biperiden using population PK-PD modeling…
To evaluate if hepcidin levels can predict response to iron therapy with either ferrous fumarate, ferric maltol, and intravenous iron in patients with IBD.
