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.
