Carbidopa Levodopa Maximum Dosage
Sinemet-CR: This has to be determined by careful titration thru your doctor. Initial dose is usually 50-200. Consult your Neurologist. ...Read more
Variable, but: In my experience, the maximum Sinemet (carbidopa and levodopa) dosing is the 25/250 tab four times daily, and if this seems to wear off, one can add Comtan (entacapone). Problem with going too high with L-DOPA is incidence of dyskinesias. ...Read more
Dosages: Dosages are adjusted for the specific needs of each patient - there is no standard dose for any specific time period. Sinemet (carbidopa and levodopa) comes in carbadopa-levodopa doses of 10-100, 25-250, and 25-100. These can be combined and given at various times throughout the day to best relieve the symptoms of parkinson's disease. If you are not sure of your dose or the dose of someone you are caring for, you need to call the doctor that prescribed the medication to clarify. Good luck! ...Read more
Which is more likely to increase psychoses. Increasing stalevo (carbidopa and levodopa and entacapone) from 125 to 150 on the same schedule or changing the dosage from 6 to 7 per day?
Less risk by inc frq: In the treatment of Parkinson's patients with Sinemet (carbidopa and levodopa) it is generally believed that increased frequency of medication dosage is preferable for a variety of reasons including less risk of precipitating psychoses by the medication. Having said that-the most honest answer is "you will never know until you try it." ...Read more
When switching from regular Sinemet (carbidopa and levodopa) to CR, do you need to add little more CR to achieve the same dose of the regular Sinemet (carbidopa and levodopa)?
Not usually: You can usually use the same dose of Sinemet (carbidopa and levodopa) CR as you had of the regular Sinemet (carbidopa and levodopa). You may not feel it "kick in" as strongly but it should work just as effectively and hopefully last longer for you. Good luck. ...Read more
Depends...: Regretfully, there is no typical Sinemet (carbidopa and levodopa) dose following DBS, given that each patient is different and their need for treatment varies. Discuss this with your neurologist. ...Read more
Typical- Misnomer...: Quite honestly, as a neurologist I've found LESS AND LESS TYPICAL starting doses of any of the anit-parkinsonian medications as I get farther into my career. Oh, sure there are textbook numbers but when the actual DIAGNOSIS of PD cannot be firmly made at times for years after presentation should there really be such as a thing as a TYPICAL starting dose of Sinemet (carbidopa and levodopa)? Commonly seen is 25/100 3x/day. ...Read more

Parkinsons - Is it true that the bioequivalent dose of Sinement CR is 75-80% of the regular Sinemet (carbidopa and levodopa)?
The bioequivalent dose actually depends on the dose that is needed, your metabolism, what other medicines you use, an your experience with these medicines.
The ratio of sinemet (carbidopa and levodopa) CR to regular sinemet (carbidopa and levodopa) may vary from 50% to 100% of the regular dose. Your number (75%) is right inbetween.

Different timing: CR is sustained release. Regular lasts only a few hours and tends to have more peaks and troughs. One can use both. Regular is given 3 to 4 times a day. ...Read more
What is the typical starting dose of sinemet (carbidopa and levodopa) for a patient with parkinsons? How long do you need to take it feel its effects? Several weeks?
Varies: Different movement disorder neurologists have varying treatment regimens, but I prefer to start sinemet (carbidopa and levodopa) at low dosing initially, such as 10/100 3-4 times daily in divided dosing. With your dbs, the regimen may require a different plan. ...Read more
Blocks breakdown: Carbidopa acts to block the enzyme aromatic-l-amino-acid decarboxylase which converts l-dopa to dopamine. Since it cannot get into the brain it works in the rest of the body (periphery). When given in combination with l-dopa in parkinson's disease, it inhibits the conversion of l-dopa to Dopamine in the body so that more is available to be converted in the brain where it is needed. ...Read more

Neither: Generic drugs are held to standards where the manufacturer must prove "bioequivalence" to the branded drug. The molecules must be structurally the same, and the same standard of quality and purity must be met. The pills and the packaging themselves may look different, but the active ingredient is the same. It can be thought of as the difference between clorox bleach and safeway brand bleach. ...Read more

Probably not bad: I had to look up rhodiola as that was one I had never heard of. There are no reasons, at least theoretically, that the two should be a problem. I did a literature search and there are no articles in the medical literature looking at rhodiola and sinemet (carbidopa and levodopa). There are some laboratory papers that suggest rhodiola should be helpful in pd, but I could not find any clinical studies in people. ...Read more
