Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The most common reactions associated with fenoldopam use are headache, cutaneous dilation (flushing), nausea, and hypotension, each reported in more than 5% of patients.

Adverse reactions occurring more than once in any dosing group (once if potentially important or plausibly drug-related) in the fixed-dose constant-infusion studies are presented in Table 5. There was no clear dose relationship, except possibly for headache, nausea, flushing.

Table 5: Adverse reactions in fixed-dose studies occurring in > 5% of subjects on fenoldopam

Post-Marketing Experience

The following adverse reactions have been identified during post approval use of Corlopam. Because these reactions are reported voluntarily from a population of uncertain size, it is difficult to reliably estimate their frequency or evaluate a causal relationship to drug exposure. Voluntary reports of adverse reactions temporally associated with Corlopam that have been received since market introduction and that may have no causal relationship with the drug include the following:

Cardiac Disorders — Cardiogenic shock

Vascular Disorders — Hypotension

Gastrointestinal Disorders — Abdominal distension

Investigations — Electrocardiogram ST segment depression, oxygen saturation decreased
