Interaksi Karbidopa, levodopa, dan entakapon dan Ropinirol

Decreasing the dose of dopaminergic medications may ameliorate this adverse reaction.

Impulse Control/Compulsive Behaviors Reports suggest that patients can experience intense urges to gamble, increased sexual urges, intense urges to spend money, binge or compulsive eating, and/or other intense urges, and the inability to control these urges while taking one or more of the medications, including ropinirole, that increase central dopaminergic tone.

Withdrawal-Emergent Hyperpyrexia and Confusion A symptom complex resembling the neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction of, withdrawal of, or changes in, dopaminergic therapy.

In controlled clinical trials in patients with Parkinson’s disease, syncope was observed more frequently in patients receiving ropinirole than in patients receiving placebo (early Parkinson’s disease without levodopa [L-dopa]: ropinirole 12%, placebo 1%; advanced Parkinson’s disease: ropinirole 3%, placebo 2%).

These symptoms generally do not respond to levodopa.

Hypotension, orthostatic hypotension, and syncope are observed in patients treated with drugs that increase central dopaminergic tone including Carbidopa, levodopa and entacapone tablets.

Patients may be unable to control these urges while taking one or more of the medications generally used for the treatment of Parkinson’s disease and which increase central dopaminergic tone, including entacapone taken with levodopa and carbidopa.

Although these adverse reactions may be related to the ergoline structure of these compounds, a possible causal role of nonergot derived drugs (e.g., entacapone, levodopa), which increase dopaminergic activity, has also been considered.

Hallucinations and/or Psychotic-Like Behavior Dopaminergic therapy in patients with Parkinson’s disease has been associated with hallucinations.

Fibrotic Complications Cases of retroperitoneal fibrosis, pulmonary infiltrates, pleural effusion, and pleural thickening have been reported in some patients treated with ergot derived dopaminergic agents.
