"Sept. 19, 2012 -- The FDA is investigating a possible risk of heart failure linked to Mirapex, a drug used to treat Parkinson's disease and restless legs syndrome.
Officials say recent studies suggest a potential raised risk of heart "...

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse event rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug (or of another development program of a different formulation of the same drug) and may not reflect the rates observed in practice.
During the premarketing development of MIRAPEX ER tablets, patients with early Parkinson's disease were treated with MIRAPEX ER tablets, placebo, or immediate-release pramipexole tablets. In addition, a randomized, double-blind, parallel group trial was conducted in 156 early Parkinson's disease patients (Hoehn & Yahr Stages I-III) to assess overnight switching of immediate-release pramipexole tablets to MIRAPEX ER tablets. In this latter study, concomitant treatment with stable doses of levodopa, monoamine oxidase B inhibitor (MAOB-I) drugs, anticholinergics, or amantadine, individually or in combination, was allowed. In a third trial, advanced Parkinson's disease patients received MIRAPEX ER tablets, placebo, or immediate-release pramipexole tablets as adjunctive therapy to levodopa.
Early Parkinson's Disease
The most commonly observed adverse events ( ≥ 5% and more frequent than placebo) after 33 weeks of treatment with MIRAPEX ER tablets in the trial of early Parkinson's disease patients were somnolence, nausea, constipation, dizziness, fatigue, hallucinations, dry mouth, muscle spasms, and peripheral edema.
Twenty four of 223 (11%) patients treated with MIRAPEX ER tablets for 33 weeks discontinued treatment due to adverse events compared to 4 of 103 (4%) patients who received placebo and approximately 20 of 213 (9%) patients who received immediate-release pramipexole tablets. The adverse event most commonly causing discontinuation of treatment with MIRAPEX ER tablets was nausea (2%).
Table 1 lists adverse events that occurred with a frequency of at least 2% with MIRAPEX ER and were more frequent than with placebo during 33 weeks of treatment in a double-blind, placebo-controlled study in early Parkinson's disease. In this study, patients did not receive concomitant levodopa; however, levodopa was permitted as rescue medication. Adverse events were usually mild (38%) or moderate (41%) in intensity.

Because this study used a flexible dose titration design, it was not possible to assess the effects of dose on the incidence of adverse events.
Adverse events can initially occur in either the titration or maintenance phase. Some adverse events developed in MIRAPEX ER-treated patients during the titration phase and persisted ( ≥ 7 days) into the maintenance phase (i.e., MIRAPEX ER % - placebo % = treatment difference ≥ 2%); persistent adverse events were somnolence, nausea, constipation, fatigue, and dry mouth.
A double-blind, randomized, parallel group trial evaluated the tolerability of an overnight switch from immediate-release pramipexole tablets to MIRAPEX ER tablets at the same daily dose in 156 early Parkinson's disease patients with or without levodopa. One of 104 patients switched from immediate-release pramipexole tablets to MIRAPEX ER tablets discontinued due to adverse events (vertigo and nausea).
Advanced Parkinson's Disease
The most commonly observed adverse events ( ≥ 5% and greater frequency than in placebo) during 18 weeks of treatment with MIRAPEX ER tablets in the trial of advanced Parkinson's disease patients with concomitant levodopa were dyskinesia, nausea, constipation, hallucinations, headache, and anorexia.
Eight of 164 (5%) patients treated with MIRAPEX ER tablets for 18 weeks discontinued treatment due to adverse events compared to 7 of 178 (4%) patients who received placebo and 8 of 175 (5%) patients who received immediate-release pramipexole tablets. The most common adverse events leading to discontinuation of treatment with MIRAPEX ER tablets were nausea (1%) and hallucination (1%).
Table 2 lists adverse events that occurred with a frequency of at least 2% with MIRAPEX ER and were more frequent than with placebo during 18 weeks of treatment in patients with advanced Parkinson's disease treated with MIRAPEX ER tablets. In this study, MIRAPEX ER tablets, immediate-release pramipexole tablets, or placebo was administered to patients who were also receiving concomitant levodopa. Adverse events were usually mild (32%) or moderate (17%) in intensity.

Because this flexible dose study used a titration design, it was not possible to assess the effects of dose on the incidence of adverse events.
Adverse events can initially occur in either the titration or maintenance phase. Some adverse events developed in MIRAPEX ER-treated patients during the titration phase and persisted ( ≥ 7 days) into the maintenance phase (i.e., MIRAPEX ER % - placebo % = treatment difference ≥ 2%); persistent adverse events were dyskinesia and insomnia.
During the development of MIRAPEX ER tablets, no systematic abnormalities on routine laboratory testing were noted. Therefore, no specific guidance is offered regarding routine monitoring; the practitioner retains responsibility for determining how best to monitor the patient in his or her care.

The following adverse reactions have been identified during post-approval use of immediate-release pramipexole tablets, primarily in Parkinson's disease patients. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Decisions to include these reactions in labeling are typically based on one or more of the following factors: (1) seriousness of the reaction, (2) frequency of reporting, or (3) strength of causal connection to pramipexole tablets. Similar types of events were grouped into a smaller number of standardized categories using the MedDRA terminology: abnormal behavior, abnormal dreams, accidents (including fall), blackouts, compulsive shopping, fatigue, hallucinations (all kinds), headache, hypotension (including postural hypotension), inappropriate antidiuretic hormone secretion (SIADH), increased eating (including binge eating, compulsive eating, and hyperphagia), libido disorders (including increased and decreased libido, and hypersexuality), pathological gambling, pruritus, syncope, vomiting, and weight increase.

No drug interaction studies were conducted with MIRAPEX ER tablets since the potential for drug interactions mainly depends on the active drug substance pramipexole and not the formulation. Data are available for the immediate-release pramipexole tablet formulation [see CLINICAL PHARMACOLOGY].
Since pramipexole is a dopamine agonist, it is possible that dopamine antagonists, such as the neuroleptics (phenothiazines, butyrophenones, thioxanthenes) or metoclopramide, may diminish the effectiveness of MIRAPEX ER tablets.
Drug/Laboratory Test Interactions
There are no known interactions between pramipexole and laboratory tests.
Drug Abuse And Dependence
Pramipexole is not a controlled substance.
Abuse and Dependence
Pramipexole has not been systematically studied in animals or humans for its potential for abuse, tolerance, or physical dependence. However, in a rat model of cocaine self-administration, pramipexole had little or no effect.
