Interaction entre Carbidopa, lévodopa et entacapone et Pramipexole

For these reasons, both Parkinson’s disease patients and RLS patients being treated with dopaminergic agonists ordinarily require careful monitoring for signs and symptoms of orthostatic hypotension, especially during dose escalation, and should be informed of this risk.

…cross-sectional study suggest that patients can experience intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, binge eating, and/or other intense urges and the inability to control these urges while taking one or more of the medications, including pramipexole dihydrochloride tablets, that increase central dopaminergic tone.

…pramipexole in the clinical development program, 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, withdrawal of, or changes in dopaminergic therapy.

Rebound and Augmentation in RLS Reports in the literature indicate treatment of RLS with dopaminergic medications can result in rebound: a worsening of symptoms following treatment cessation with greater intensity than described before starting treatment.

In the four double-blind, placebo-controlled trials in advanced Parkinson’s disease, where patients received pramipexole dihydrochloride tablets and concomitant levodopa, hallucinations were observed in 16.5% (43 of 260) of patients receiving pramipexole dihydrochloride tablets compared with 3.8% (10 of 264) of patients receiving placebo.

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.
