- Brief Summary
The objective of this study is to compare the pharmacokinetics and pharmacodynamics of IPX054, carbidopa-levodopa immediate-release tablets, and carbidopa-levodopa controlled-release tablets in subjects with idiopathic Parkinson's disease.
- Detailed Description
IPX054 contains two different drugs called levodopa and carbidopa in one tablet.
* levodopa turns into a material called 'dopamine' in your brain. The dopamine helps to improve the symptoms of your Parkinson's disease.
* carbidopa belongs to a group of medicines called 'aromatic amino acid decarboxylase inhibitors'. It helps levodopa work more effectively by slowing the speed at which levodopa is broken down in your body.
