L-Dopa is a prodrug used to treat Parkinson's Disease. It crosses the blood brain barrier with the aid of Phe-Trp-L-aromatic acid transporters and is then turned into dopamine through decarboxylation. However, it is also capable of producing large amounts of dopamine in peripheral areas by stimulating the chemoreceptor trigger zone and these dopamine can produce side effects in peripheral body parts. Carbidopa is hence added to inhibit DOPA decarboxylase in peripheral areas so that there will be fewer of these side effects.
Levodopa itself is not well tolerated, which is why it is combined with carbidopa. Carbidopa decreases peripheral metabolism of levodopa, which allows for lower doses of levodopa and less-severe side effects.
They include carbidopa and benserazide

nausea and vomiting low blood pressure, particularly when standing up, resulting in dizziness and fainting dyskinesias (abnormal movements including twisting and tics) in at least 50% of patients agitation hallucinations
The medication Levodopa or L-dopa often succeeds in lessening muscle rigidity and tremors , and is often given in conjunction with the drug Carbidopa
Catechol-O-methyltransferase (COMT) inhibitors are a class of medication used in combination with levodopa and carbidopa in the treatment of symptoms of Parkinson's disease (PD).
the two most-commonly prescribed forms of levodopa include an amino-acid-decarboxylase (AADC) inhibitor: carbidopa (in Sinemet) or benzaseride (in Madopar).
Need to Take glucose tollerance test and if sugar level is detected in blood then insulin needs to be admistered to keep the sugar levals under control
Lack of L-dopa is the major problem. Therefore, symptoms improve with the use of the centrally-acting agent, levodopa (L-dopa), and the peripherally-acting agent, carbidopa.
