Ropinirole, sold under the brand name Requip among others, is a medication used to treat Parkinson's disease (PD) and restless legs syndrome (RLS). [3] It is taken by mouth. [4]

Contents

Common side effects include sleepiness, vomiting, and dizziness. [4] Serious side effects may include pathological gambling, low blood pressure with standing and hallucinations. [3] [4] Use in pregnancy and breastfeeding is of unclear safety. [5] It is a dopamine agonist and works by triggering dopamine D2 receptors. [4]

It was approved for medical use in the United States in 1997. [4] It is available as a generic medication. [3] In 2022, it was the 163rd most commonly prescribed medication in the United States, with more than 3 million prescriptions. [6] [7]

Medical uses

Ropinirole is prescribed for mainly Parkinson's disease, restless legs syndrome, and extrapyramidal symptoms. It can also reduce the side effects caused by selective serotonin reuptake inhibitors, including Parkinsonism syndrome as well as sexual dysfunction and erectile dysfunction caused by either SSRIs [8] or antipsychotics.

A 2008 meta-analysis found that ropinirole was less effective than pramipexole in the treatment of restless legs syndrome. [9]

Side effects

Ropinirole can cause nausea, dizziness, hallucinations, orthostatic hypotension, and sudden sleep attacks during the daytime. Unusual side effects specific to D3 agonists such as ropinirole and pramipexole can include hypersexuality, punding and compulsive gambling, even in patients without a history of these behaviours. [10]

Ropinirole is also known to cause an effect known as "augmentation" when used to treat restless legs syndrome, where over time treatment with dopamine agonists will cause restless legs syndrome symptoms to become more severe. This usually leads to constant dosage increases in an attempt to offset the symptom progression. Symptoms will return to the level of severity they were experienced at before treatment was initiated if the drug is stopped; however, both ropinirole and pramipexole are known to cause painful withdrawal effects when treatment is stopped and the process of taking a patient who has been using the medication long-term off of these drugs is often very difficult and generally should be supervised by a medical professional. [11]

Ropinirole acts as a D2, D3, and D4 dopamine receptor agonist with highest affinity for D3, which are mostly found in the limbic areas. [13] It is weakly active at the 5-HT2, and α2 receptors and is said to have virtually no affinity for the 5-HT1, GABA, mAChRs, α1-, and β-adrenoreceptors. [14] It is a potent agonist of the 5-HT2B receptor, but shows biased agonism at this receptor and does not appear to pose a risk of cardiac valvulopathy. [15] [16]

Ropinirole is metabolized primarily by cytochrome P450 CYP1A2 to form two metabolites; SK&F-104557 and SK&F-89124, both of which are renally excreted, [17] and at doses higher than clinical, is also metabolized by CYP3A4. At doses greater than 24 mg, CYP2D6 may be inhibited, although this has been tested only in vitro. [2]

Society and culture

It is manufactured by GlaxoSmithKline (GSK), Mylan Pharmaceuticals, Cipla, Dr. Reddy's Laboratories and Sun Pharmaceutical. The discovery of the drug's utility in restless legs syndrome has been used as an example of successful drug repurposing. [18]

Lawsuits

In November 2012, GlaxoSmithKline was ordered by a Rennes appeals court to pay Frenchman Didier Jambart 197,000 euros ($255,824); Jambart had taken ropinirole from 2003 to 2010 and exhibited risky hypersexual behavior and gambled excessively until stopping the medication. [19]

Neuroleptic malignant syndrome (NMS) is a rare but life-threatening reaction that can occur in response to antipsychotics (neuroleptic) or other drugs that block the effects of dopamine. Symptoms include high fever, confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. Complications may include muscle breakdown (rhabdomyolysis), high blood potassium, kidney failure, or seizures.

<span class="mw-page-title-main">Restless legs syndrome</span> Neurological disorder that causes a strong urge to move ones legs

Restless legs syndrome (RLS), (also known as Willis–Ekbom disease(WED), is a neurological disorder, usually chronic, that causes an overwhelming urge to move one's legs. There is often an unpleasant feeling in the legs that improves temporarily by moving them. This feeling is often described as aching, tingling, or crawling in nature. Occasionally, arms may also be affected. The feelings generally happen when at rest and therefore can make it hard to sleep. Sleep disruption may leave people with RLS sleepy during the day, with low energy, and irritable or depressed. Additionally, many have limb twitching during sleep, a condition known as periodic limb movement disorder. RLS is not the same as habitual foot-tapping or leg-rocking.

<span class="mw-page-title-main">Dopamine agonist</span> Compound that activates dopamine receptors

A dopamine agonist is a compound that activates dopamine receptors. There are two families of dopamine receptors, D1-like and D2-like. They are all G protein-coupled receptors. D1- and D5-receptors belong to the D1-like family and the D2-like family includes D2, D3 and D4 receptors. Dopamine agonists are primarily used in the treatment of the motor symptoms of Parkinson's disease, and to a lesser extent, in hyperprolactinemia and restless legs syndrome. They are also used off-label in the treatment of clinical depression. Impulse control disorders are associated with the use of dopamine agonists for whatever condition.

Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain's cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE). The symptoms can be acute (short-term) or chronic (long-term). They include movement dysfunction such as dystonia, akathisia, parkinsonism characteristic symptoms such as rigidity, bradykinesia, tremor, and tardive dyskinesia. Extrapyramidal symptoms are a reason why subjects drop out of clinical trials of antipsychotics; of the 213 (14.6%) subjects that dropped out of one of the largest clinical trials of antipsychotics, 58 (27.2%) of those discontinuations were due to EPS.

It is characterized by severely disinhibited patterns of behavior, leading to problems such as addiction to the offending medication, gambling addiction, or compulsive sexual behavior, along with a general orientation towards immediate gratification. It typically occurs in people with Parkinson's disease or restless legs syndrome (RLS) who have taken dopamine agonist medications for an extended period of time.

<span class="mw-page-title-main">Sumanirole</span> Chemical compound

Sumanirole (PNU-95,666) is a highly selective D2 receptor full agonist, the first of its kind to be discovered. It was developed for the treatment of Parkinson's disease and restless leg syndrome. While it has never been approved for medical use it is a highly valuable tool compound for basic research to identify neurobiological mechanisms that are based on a dopamine D2-linked (vs. D1-, D3-, D4-, and D5-linked) mechanism of action.

Dopamine therapy is the regulation of levels of the neurotransmitter dopamine through the use of either agonists, or antagonists; and has been used in the treatment of disorders characterized by a dopamine imbalance. Dopamine replacement therapy (DRT) is an effective treatment for patients with decreased levels of dopamine. Often dopamine antagonists, compounds that activate dopamine receptors in the absence of that receptor's physiological ligand, the neurotransmitter dopamine, are used in this therapy. DRT has been shown to reduce symptoms and increase lifespan for patients with Parkinson's disease. Dopamine regulation plays a critical role in human mental and physical health. The neurons that contain the neurotransmitter are clustered in the midbrain region in an area called the substantia nigra. In Parkinson's patients, the death of dopamine-transmitting neurons in this area leads to abnormal nerve-firing patterns that cause motor problems. Research in patients with schizophrenia indicates abnormalities in dopamine receptor structure and function.

Conversely, a compound presenting as an agonist in 5-HT2B functional assays does not necessarily pose a risk for valvulopathy. In 5-HT2B calcium flux assays, certain known VHD-associated compounds displayed an agonist profile comparable to that of ropinirole, an approved treatment for Parkinson's disease (PD) and restless leg syndrome.122 Because ropinirole is not known to be associated with VHD or similar cardiopathies, it is thought that calcium flux may not be the optimal assay for screening 5-HT2B agonists for potential VHD-related risks. In additional readouts of 5-HT2B receptor activation (calcium-sensitive NFAT-mediated transcription of a β-lactamase reporter gene, accumulation of InsPs in LiCl-treated cells, recruitment of β-arrestin to agonist-occupied receptors, and phosphorylation of the extracellular signal-regulated kinase ERK2), ropinirole was found to be "distinct from the seven known valvulopathic 5- HT2B receptor agonists [studied] in that it is much less potent, albeit not less efficacious, than the VHD-associated drugs in all but one of the 5-HT2B receptor functional assays employed." 66
