Requip (ropinirole) Disease Interactions

There are 6 disease interactions with Requip (ropinirole):


Dopamine Agonists (Includes Requip) ↔ Hypotension

Severe Potential Hazard, High plausibility

Applies to: Hypotension

Dopamine agonists may impair the systemic regulation of blood pressure, with resultant orthostatic hypotension, especially during dose escalation. Therapy with dopamine agonists should be monitored carefully in patients with Parkinson's disease since they may have an impaired ability to respond to an orthostatic challenge, and also in patients receiving antihypertensive drugs.

Dopaminergic Antiparkinson Agents (Includes Requip) ↔ Psychosis

Severe Potential Hazard, Moderate plausibility

Applies to: Psychosis

Ordinarily, patients with major psychotic disorder should not be treated with dopaminergic antiparkinson agents, because of the risk of exacerbating psychosis. Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of these drugs.


Ropinirole (Includes Requip) ↔ Neuroleptic Malignant Syndrome

Severe Potential Hazard, Low plausibility

Applies to: Neuroleptic Malignant Syndrome

Neuroleptic malignant syndrome (NMS) has not occurred during administration of ropinirole, however, the syndrome has rarely been precipitated by rapid dosage reduction, abrupt discontinuation, or changes in other dopamine agonist therapy.

Ropinirole (Includes Requip) ↔ Cardiovascular Disease

Moderate Potential Hazard, Moderate plausibility

Applies to: Cardiovascular Disease

The trials of ropinirole excluded patients with significant cardiovascular disease, hence patients with cardiovascular conditions should be treated with caution.

Ropinirole (Includes Requip) ↔ Hepatic Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

The pharmacokinetic disposition of ropinirole has not been studied in patients with hepatic impairment, however, the serum concentration of ropinirole may be increased and the elimination half-life prolonged in these patients. Therapy with ropinirole should be administered cautiously in patients with hepatic impairment, and dosages titrated according to patient parameters and clinical tolerability.

Ropinirole (Includes Requip) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

Ropinirole is primarily eliminated by the kidney. Less than 10% of ropinirole is excreted unchanged in the urine. No dose adjustment is necessary in patients with moderate renal impairment (CrCl 30 to 50 mL/min). For patients with end-stage renal disease on hemodialysis, a reduced maximum dose is recommended.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
