In older people, these medications are more likely than levodopa to cause confusion, hallucinations or psychosis, so providers prescribe them less often for older people
Thus, COMT inhibitors prolong the half-life of levodopa and prevent motor Sinemet (carbidopa/levodopa) is a prescription drug used to treat Parkinson’s disease and parkinsonism
The half-life of Sinemet is 90 minutes but its effects will last for three to four This was accomplished by 3 effects: the time to onset of the levodopa effect was shortened with the addition of pramipexole, the duration of motor improvement with levodopa infusion was prolonged with pramipexole, and, at the threshold levodopa infusion, the peak finger-tapping rate was increased beyond the increase in baseline speed
Treatment with and drug titration of levodopa for intravenous administration alone may be dangerous during general anesthesia because of interactions with anesthetic agents
This means that the body may no longer respond to the drug as it once did, resulting in the need to increase the dose of the The pharmacokinetics and pharmacodynamics of levodopa are dominated by two features: the short plasma half-life of the drug and the portion of the antiparkinsonian response that parallels the plasma levodopa levels, the so-called short-duration response
