What is Sinemet Cr?
Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or the caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with SINEMET CR.
Epidemiological studies have shown that patients with Parkinson's disease have a higher risk 2- to approximately 6-fold higher of developing melanoma than the general population. Whether the increased risk observed was due to Parkinson's disease or other factors, such as drugs used to treat Parkinson's disease, is unclear. Abnormalities in blood urea nitrogen BUN and positive Coombs test have also been reported.
Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during administration of carbidopa levodopa preparations than with levodopa. Carbidopa levodopa preparations, such as SINEMET and SINEMET CR, may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucoseoxidase methods of testing for glucosuria.
However, the precursor to dopamine, levodopa, can penetrate the blood brain barrier and be converted to dopamine by amino acid decarboxylase or dopa decarboxylase enzyme. Oral administration of levodopa alone results in the rapid peripheral conversion of levodopa to dopamine which decreases the desired therapeutic effect and causes significant GI side effects such as nausea and vomiting.
Carbidopa is an inhibitor of the enzyme amino acid decarboxylase dopa decarboxylase that is responsible for the peripheral conversion of levodopa to dopamine.

It includes content provided to the PMC International archive by participating publishers. Sinemet CR produced more sustained plasma levels of levodopa, carbidopa, and 3-O methyldopa than did conventional Sinemet.
In elderly subjects, the corresponding steady-state plasma levels fluctuated in narrower ranges with Sinemet CR than those following the administration of Sinemet.
Systemic decarboxylase inhibition was comparable between the 2 regimens as indicated by the renal clearance of levodopa. The absorption of levodopa was slower and more protracted with Sinemet CR than with Sinemet.
