Carcinogenesis Mutagenesis Impairment Of Fertility
Carcinogenesis
Two-year carcinogenicity studies of rotigotine were conducted in mice at doses of 0, 3, 10, and 30 mg/kg and in rats at doses of 0, 0.3, 1, and 3 mg/kg in both studies rotigotine was administered subcutaneously once every 48 hours. No significant increases in tumors occurred in mice at doses up to 9 times the maximum recommended human dose in Parkinson’s disease .
In rats, there were increases in Leydig cell tumors and in uterine tumors at all doses. The endocrine mechanisms believed to be involved in the production of these tumors in rats are not considered relevant to humans. Therefore, there were no tumor findings considered relevant to humans at plasma exposures up to 4 to 6 times that in humans at the MRHD.
Mutagenesis
Rotigotine was negative in the in vitro bacterial reverse mutation and in the in vivo micronucleus assays. Rotigotine was mutagenic and clastogenic in the in vivo mouse lymphoma tk assay.

Reports Of Sleep Attack With Rotigotine
As with other dopamine agonists, rotigotine may cause sudden onset of sleep.1,15-17 Somnolence is a very common occurrence in people taking rotigotine and causes people to fall asleep while engaged in activities of daily living. Somnolence events have been reported as late as 1 year after starting treatment.1 In some cases this can occur without warning .1
One patient using a 6 mg/24 hours rotigotine patch experienced sudden onset of sleep while driving, and another using an 8 mg/24 hours rotigotine patch reported a brief loss of consciousness while driving.15
Before starting treatment with rotigotine advise patients of the risk of drowsiness and ask specific questions to determine whether they have pre-existing factors that may increase the risk. These factors include concomitant use of sedating medications and the presence of sleeping disorders.1
Advise patients not to drive, use tools or operate machinery until the effects of rotigotine are known. Patients who have had a sleep attack should discontinue rotigotine but if a decision is made to continue they should not drive or engage in activities where being alert is important for their safety or the safety of others .1
Animal Toxicology And/or Pharmacology
Retinal Pathology: Albino rats
Retinal degeneration was observed in albino rats in a 6-month toxicity study at the highest dose of rotigotine . Retinal degeneration was not observed in the 2-year carcinogenicity studies in albino rat or albino mouse, or in monkeys treated for 1 year. The potential significance of this effect in humans has not been established, but cannot be disregarded because disruption of a mechanism that is universally present in vertebrates may be involved.

Neupro And Other Medications
Neupro belongs to a class of medications called dopamine agonists. Drugs called dopamine antagonists work in the opposite way to dopamine agonists. Taking these types of drugs while youre using Neupro patches may cause Neupro to be less effective.
Examples of dopamine antagonists to avoid while using Neupro include:
Before taking Neupro, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.
This article does not contain all drugs that may interact with Neupro. If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.
Can I Wear Neupro Patches In A Pool Or Hot Tub
You can wear Neupro patches in a pool, but not in a hot tub.
You may bathe, shower, or swim in a pool while wearing your Neupro patch. However, avoid exposing your Neupro patch to heat sources, including hot tubs, saunas, and direct sunlight. Heat can increase the amount of Neupro your body absorbs, which can increase your risk for side effects.
Its important to be aware that water may cause your Neupro patch to loosen and become unattached. If this happens, apply a new patch for the rest of the day. The next day, replace the patch at your usual time.
If you have more questions about what to do and avoid while using Neupro patches, talk with your doctor or pharmacist.

Reason For Pbs Listing
The PBAC recommended listing of rotigotine transdermal patches on the PBS on the basis of non-inferiority to cabergoline in levodopa-treated patients with motor complications.4 The PBAC considered that there were probably fewer serious safety issues associated with the use of rotigotine compared with cabergoline, but they highlighted that the absolute magnitude of the benefit was unclear.33
The appropriate equi-effective daily doses were considered to be 8.8 mg rotigotine to 3.42 mg cabergoline.33
The PBAC was concerned that information relating to the relative incidence of important adverse events including sleep attacks, ophthalmological adverse reactions and fibrosis was incomplete.33
What Is A Rotigotine Skin Patch And How Does It Work
Rotigotine is a type of dopamine agonist medication. Rotigotine comes in the form of a skin patch which you put onto your skin to release your medication. Neupro is the brand name for rotigotine.
A rotigotine skin patch releases your dopamine agonist medication slowly over a 24-hour period.
How do dopamine agonist medications work?
Dopamine is a chemical messenger made in the brain. The symptoms of Parkinsons appear when dopamine levels become too low.
This is because many of the cells in your brain that produce dopamine have died or are dying. Taking dopamine as a drug doesnt work because it cannot cross the blood brain barrier. To get around this, doctors use other medication that can act in a similar way. One approach is to use dopamine agonist drugs, which act like dopamine to stimulate your nerve cells.
Rotigotine can be used at any stage of Parkinsons. It is used on its own, with levodopa medication or with other Parkinsons medication. If it is used with levodopa, this will usually happen later on in the condition when levodopa can be less effective and more doses are needed.
The patient information leaflet that comes with your medication will give you full details about how to use each patch correctly. We have included some key information here.
You need to apply a new patch every day. This should be done at the same time each day. A good time to put on a new patch is in the morning after your bath or shower.

Pharmacokinetics of Rotigotine
DrugDrug Interactions
Rotigotine showed no pharmacokinetic drugdrug interactions with omeprazole,17 domperidone34 or levodopa/carbidopa.35 However, as with other dopamine agonists, when given concomitantly rotigotine may potentiate the adverse reactions of levodopa, including the exacerbation of pre-existing dyskinesia.
Clinical Studies of Rotigotine
Currently published clinical studies of rotigotine in advanced PD include two large-scale phase III studies and three phase II trials . Overall, these studies indicated that rotigotine is effective for the treatment of levodopa-related motor complications as well as for motor symptom control in advanced PD.

Effect on Sleep Quality and Nocturnal Motor Problems
A significant improvement in the PD sleep scale score of 7.7 and 7.1 points in the pramipexole and rotigotine groups, respectively, compared with placebo was observed.40 Furthermore, in an open-label study , patients showed significant improvements in nocturnal and motor status upon awakening and experienced significantly fewer episodes of nocturia after four weeks of rotigotine treatment.19,45

Periodic Limb Movement Disorder
Periodic limb movement disorder is a sleep disorder characterised by excessive involuntary and periodic movements of the limbs during sleep, leading to arousals, sleep fragmentation, and subsequent excessive daytime sleepiness . It is often, but not always, associated with RLS/WED and also commonly observed in patients with PD .
One open-label study confirmed the efficacy of the rotigotine transdermal patch in reducing periodic limb movements as measured by video PSG recordings in patients with PD.
What can be recommended?
The relevance of PLMD in PD is questionable and unclear. These studies have not specifically investigated the effects of rotigotine on RLS in PD. As such, in spite of the attenuation of PLMD, rotigotine cannot specifically be recommended for PD-RLS at this stage, although it is classified as efficacious for RLS .
Perform Regular Cardiac Review As Part Of Physical Examination
Cabergoline and pergolide increase the risk of valvular heart disease, but it is not known if this is true of rotigotine.25,26
The incidence of cardiac valve abnormalities was similar between rotigotine and placebo treatment groups in controlled trials, but this finding should be interpreted with caution because of the small sample size and short duration of studies. Cardiac valve abnormalities have been observed in open-label trials of rotigotine.1
Perform regular cardiovascular review as part of a physical examination of people taking rotigotine, including echocardiogram to test for potential presence of valvular disease, with clinical diagnostic monitoring for the development of cardiac valvular disease or fibrosis, as appropriate.27
After the initial echocardiogram before starting treatment, the next echocardiogram should occur within the first 36 months of treatment. Subsequent echocardiograms should occur every 612 months.27

What Does Neupro Do For Parkinsons
Rotigotine is classed as a non-ergoline dopamine agonist. Dopamine agonists work by imitating the action of dopamine in the brain by binding to dopamine receptors that help to control the bodys ability to move properly.
Exactly how rotigotine works in the body for the treatment of Parkinsons disease or restless legs syndrome is not fully understood. However, it is thought to be linked to rotigotines capacity to stimulate the dopamine receptors in the brain.
Neupro Side Effects And How To Avoid Them
Neupro is a brand-name medication manufactured by UCB, Inc. It is classified as a non-ergoline dopamine agonist and is used for the treatment of Parkinson Disease. While Neupro is generally well tolerated, there are some potential side effects that people should be aware of. The most common side effects of Neupro include problems with sleep.Less common, but more serious side effects, can consist of severe allergic reactions.

Indirect Comparisons Suggest Similar Efficacy To That Of Other Dopamine Agonists
A meta-analysis comparing the benefits and harms of adjuvant treatments for Parkinson’s disease suggests that the efficacy of dopamine agonists, including rotigotine, at reducing off-time and motor symptoms may be better than that of MAO-B inhibitors such as rasagiline and selegiline and COMT inhibitors such as entacapone.13
This study also suggests that the effect of rotigotine is similar to that of other dopamine agonists at reducing off-time and improving the UPDRS activities of daily living score. However, rotigotine may be less effective than pramipexole at improving the UPDRS motor score.13
The risk of dyskinesia with rotigotine adjunctive therapy may be less than with pergolide or ropinirole.13

Abstract
1. Introduction
Rotigotine is a nonergoline dopamine receptor agonist with D15 receptor activity and selective serotonergic and adrenergic activity . The rotigotine transdermal patch can maintain stable plasma concentrations over 24h with a single daily application due to the continuous transdermal delivery . RTP is indicated as a monotherapy for the treatment of early stage Parkinsons disease , as well as a combination therapy with levodopa. RTP has some advantages over other nonergoline dopamine agonists, such as pramipexole and ropinirole, including reduced adverse effects related to gastrointestinal disturbances , impulse control disorder , and cognitive decline . Currently, there are six approved application sites .
In this study, we aimed to assess the adequate attachment site of RTP where application site reactions are less severe than those in six approved application sites. Then, we focused on the shin because it is very easy for the patients to attach RTP on the shin by themselves.

Visual disturbance and eye conditions have been reported in open-label trials and their incidence was increased in people taking rotigotine compared with controls during placebo-controlled trials.1 In addition, there is a potential risk of retinal degeneration.1 Ophthalmological monitoring is recommended at regular intervals for early detection of visual abnormalities.1,28
Rotigotine Pharmacology And Why It May Help With Sleep Related Problems In Parkinsons Disease
RTG is a non-ergolinic aminotetralin dopamine agonist delivered using a silicone-based transdermal patch. The transdermal formulation has proven to be useful due to RTGs extensive first-pass gastrointestinal metabolism, short elimination half-life after intravenous administration, and high lipid soluble properties.,, The important advantages of a 24-hour delivery system, bypassing the gastrointestinal system and a once daily application have been previously described. Caregivers perceived advantages over oral therapies have also been highlighted recently, adding a much needed perspective in PD management.
RTG is a D3/D2/D1 dopamine agonist with antagonist activity at 2B receptors and weak, but significant, agonistic activity at 5-HT1A., , Analysis of three studies in healthy subjects and early PD confirm the sustained and steady maintenance of RTG plasma levels overnight with a continuous transdermal delivery system. Moreover, together with apomorphine, RTG is one of the few dopamine agonists extensively used in clinical practice that has significant effect on D1-type receptors.

Dont Miss: What Are The Initial Symptoms Of Parkinsons Disease
Potential For Compulsive Behaviours
People treated with dopamine agonists, including rotigotine, have reported compulsive behaviours such as increased libido, hypersexuality, repetitive meaningless actions , binge eating and pathological gambling.18-22 These symptoms are generally reversible on rotigotine dose reduction or discontinuation.1
In a safety analysis of rotigotine, pathological gambling was the most frequently reported compulsive behaviour.23 It has been described in case reports, along with punding and hypersexuality, in patients treated with adjunctive rotigotine.24 The incidence of increased libido, hypersexuality, punding and pathological gambling in studies of patients treated with rotigotine was 0.1% to 1% the incidence of binge eating was 0.01% to 0.1%.
Inform patients and carers about the risk of compulsive behaviour and ask about the development of new or increased urges while being treated with rotigotine.

How Neupro Patches Work
Patients with Parkinsons disease have reduced levels of dopamine, a naturally occurring chemical messenger found in the brain.
This is caused by the death of nerve cells that produce dopamine. Decreased dopamine levels in the brain make it difficult for Parkinsons patients to move normally and also cause non-motor symptoms.
Neupro patches work by delivering the dopamine agonist rotigotine through the skin directly into the bloodstream. Rotigotine then stimulates dopamine receptors in the brain, mimicking the action of dopamine.
By doing that, the therapy helps to ease motor and non-motor symptoms in patients with Parkinsons disease.
Rotigotine Patch For Parkinsons Disease Recalled
If youre using the Neupro patch for Parkinsons disease, talk to your neurologist about switching you to a different medication and adjusting your dosage.
For those of you on the patch Neupro: Your neurologist will need to adjust your dosage because the drug is being recalled.
The skin patch was approved by the Food and Drug Administration in May 2007 to treat symptoms of early Parkinsons disease. Neupro works by delivering the drug rotigotine continuously through the skin using a silicone-based patch that is replaced every 24 hours. Rotigotine activates dopamine receptors in the body to compensate for the loss of dopamine-producing brain cells in Parkinsons.
The recall was prompted by a manufacturing problem that caused some of the skin patches to contain lower doses of the medication and thus be less effective. The company that makes the drug, UCB, said the recall will mean that Neupro will soon be out of stock. Therefore, if you currently take the drug, your neurologist must lower your dosage and eventually switch you to a similarbut oralmedication. Some of these drugs may be available in liquid form.
Anna DePold Hohler, M.D., assistant professor of neurology at Boston University, said that gradually lowering your dosage of rotigotine should ensure that you dont experience a significant worsening in symptoms.
