Lodosyn
Lodosyn generic name: Carbidopa
What is Lodosyn used for?
This medication is used with a combination levodopa/carbidopa product to treat symptoms of Parkinson's disease or Parkinson-like symptoms (such as shakiness, stiffness, difficulty moving). Carbidopa must be taken together with a drug that contains levodopa to be effective. If used alone, carbidopa has no effect on Parkinson's symptoms. Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa changes into dopamine in the brain, helping to control movement. Carbidopa prevents the breakdown of levodopa in the bloodstream so more levodopa can enter the brain. Carbidopa can also reduce some of levodopa's side effects such as nausea and vomiting.
