Ropinirole in the Requip form is available in various preparations, ranging from a mg tablet to a 5 mg tablet. ropinirole hydrochloride 0.25 mg The primary reason is dose titration. This implies that the person taking Requip has to closely interact and communicate with the primary care physician with regard to how much should actually be taken by the patient.

Supplemental doses after haemodialysis are not required see section 5. Although a dose adjustment is not required, ropinirole dose should be individually titrated, with careful monitoring of tolerability, to the optimal clinical response. Requip is not recommended for use in children below 18 years of age due to a lack of data on safety and efficacy. Ropinirole has been associated with somnolence and episodes of sudden sleep onset, particularly in patients with Parkinson's Disease.

Sudden onset of sleep during daily activities, in some cases without awareness or warning signs, has been reported uncommonly. Patients must be informed of this and advised to exercise caution while driving or operating machines during treatment with ropinirole.

Furthermore, a reduction of dosage or termination of therapy may be considered. Impulse control disorders Patients should be regularly monitored for the development of impulse control disorders.

Patients and carers should be made aware that behavioural symptoms of impulse control disorders including pathological gambling, increased libido, hypersexuality, compulsive spending or buying, binge eating and compulsive eating can occur in patients treated with dopamine agonists including ReQuip.

Impulse control disorders were reported especially at high doses and were generally reversible upon reduction of the dose or treatment discontinuation. Do not increase your dose or take it more often than directed. If you stop taking this medication for several days, you may need to increase your dose slowly back to your previous dosage.

Talk with your doctor about how to restart the medication. Do not stop taking this medication without consulting your doctor. If you suddenly stop taking this drug, withdrawal symptoms such as fever, muscle stiffness, and confusion may occur. Patients should be instructed to take ropinirole hydrochloride only as prescribed. If a dose is missed, patients should be advised not to double their next dose.

Ropinirole hydrochloride tablets can be taken with or without food. Patients may be advised that taking ropinirole hydrochloride tablets with food may reduce the occurrence of nausea. However, this has not been established in controlled clinical trials. Patients should be advised that they may develop postural orthostatic hypotension with or without symptoms such as dizziness, nausea, syncope, and sometimes sweating. Accordingly, patients should be cautioned against rising rapidly after sitting or lying down, especially if they have been doing so for prolonged periods, and especially at the initiation of treatment with ropinirole hydrochloride.

Patients should be alerted to the potential sedating effects associated with ropinirole hydrochloride, including somnolence and the possibility of falling asleep while engaged in activities of daily living. Patients should be advised that if increased somnolence or episodes of falling asleep during activities of daily living e.

Because of possible additive effects, caution should be advised when patients are taking other sedating medications or alcohol in combination with ropinirole hydrochloride and when taking concomitant medications that increase plasma levels of ropinirole e. Because of the possible additive sedative effects, caution should also be used when patients are taking alcohol or other CNS depressants e.

Patients should be informed they may experience hallucinations unreal visions, sounds, or sensations while taking ropinirole hydrochloride. These were uncommon in patients taking ropinirole hydrochloride for Restless Legs Syndrome.

The risk is greater in patients with Parkinson's disease; the elderly are at greater risk than younger patients with Parkinson's disease; and the risk is greater in patients who are taking ropinirole hydrochloride with L-dopa, or taking higher doses of ropinirole hydrochloride.

Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges or other urges while being treated with ropinirole hydrochloride. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges or other intense urges while taking ropinirole hydrochloride.

Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking ropinirole hydrochloride. In vitro metabolism studies showed that CYP1A2 was the major enzyme responsible for the metabolism of ropinirole.

There is thus the potential for substrates or inhibitors of this enzyme when coadministered with ropinirole to alter its clearance. Therefore, if therapy with a drug known to be a potent inhibitor of CYP1A2 is stopped or started during treatment with ropinirole hydrochloride, adjustment of the dose of ropinirole hydrochloride may be required.

Co-administration of ropinirole hydrochloride 2 mg 3 times daily with digoxin 0. Administration of theophylline mg twice daily, a substrate of CYP1A2 did not alter the steady-state pharmacokinetics of ropinirole 2 mg 3 times daily in 12 patients with Parkinson's disease.

Population pharmacokinetic analysis revealed that estrogens mainly ethinylestradiol: Dosage adjustment may not be needed for ropinirole hydrochloride in patients on estrogen therapy because patients must be carefully titrated with ropinirole to tolerance or adequate effect. Key diagnostic criteria for RLS are: Difficulty falling asleep may frequently be associated with moderate-to-severe RLS.

Patients treated with ropinirole hydrochloride have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes resulted in accidents. Although many of these patients reported somnolence while on ropinirole hydrochloride, some perceived that they had no warning signs such as excessive drowsiness, and believed that they were alert immediately prior to the event.

Some of these events have been reported as late as 1 year after initiation of treatment. Many clinical experts believe that falling asleep while engaged in activities of daily living always occurs in a setting of preexisting somnolence, although patients may not give such a history.

For this reason, prescribers should continually reassess patients for drowsiness or sleepiness, especially since some of the events occur well after the start of treatment. Prescribers should also be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Before initiating treatment with ropinirole hydrochloride, patients should be advised of the potential to develop drowsiness and specifically asked about factors that may increase the risk with ropinirole hydrochloride such as concomitant sedating medications, the presence of sleep disorders other than Restless Legs Syndrome , and concomitant medications that increase ropinirole plasma levels e.

If a patient develops significant daytime sleepiness or episodes of falling asleep during activities that require active participation e.

If a decision is made to continue ropinirole hydrochloride, patients should be advised to not drive and to avoid other potentially dangerous activities. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living Syncope: Syncope, sometimes associated with bradycardia, was observed in association with ropinirole in both Parkinson's disease patients and RLS patients.

In the 2 double-blind, placebo-controlled studies of ropinirole hydrochloride in patients with Parkinson's disease who were not being treated with L-dopa, Most of these cases occurred more than 4 weeks after initiation of therapy with ropinirole hydrochloride, and were usually associated with a recent increase in dose.

Of patients being treated with both L-dopa and ropinirole hydrochloride in placebo-controlled advanced Parkinson's disease trials, there were reports of syncope in 6 2.

In patients with RLS, of patients treated with ropinirole hydrochloride in week placebo-controlled trials, there were reports of syncope in 5 1. Because the studies of ropinirole hydrochloride excluded patients with significant cardiovascular disease, it is not known to what extent the estimated incidence figures apply to either Parkinson's disease or RLS patients in clinical practice.

Therefore, patients with severe cardiovascular disease should be treated with caution. Two of 47 Parkinson's disease patient volunteers enrolled in phase 1 studies had syncope following a 1-mg dose. In 2 studies in RLS patients that used a forced titration regimen and orthostatic challenge with intensive blood pressure monitoring, 1 of 55 RLS patients treated with ropinirole hydrochloride compared with 0 of 27 patients receiving placebo reported syncope.

In phase 1 studies including healthy volunteers, 1 patient developed hypotension, bradycardia, and sinus arrest of 26 seconds accompanied by syncope; the patient recovered spontaneously without intervention.

One other healthy volunteer reported syncope. Dopamine agonists, in clinical studies and clinical experience, appear to impair the systemic regulation of blood pressure, with resulting postural hypotension, especially during dose escalation. Parkinson's disease patients, in addition, appear to have an impaired capacity to respond to a postural challenge. Although the clinical trials were not designed to systematically monitor blood pressure, there were individual reported cases of postural hypotension in early Parkinson's disease without L-dopa in patients treated with ropinirole hydrochloride.

Hepatic Impairment The pharmacokinetics of Ropinirole have not been studied in patients with hepatic impairment. Overdosage The symptoms of overdose with Ropinirole tablets are related to its dopaminergic activity. General supportive measures are recommended. Vital signs should be maintained, if necessary. In clinical trials, there have been patients who accidentally or intentionally took more than their prescribed dose of Ropinirole. The largest overdose reported with Ropinirole in clinical trials was mg taken over a 7-day period Additional symptoms reported in cases of overdose included vomiting, increased coughing, fatigue, syncope, vasovagal syncope, dyskinesia, agitation, chest pain, orthostatic hypotension, somnolence, and confusional state.

Ropinirole - Clinical Pharmacology Mechanism of Action Ropinirole is a non-ergoline dopamine agonist. The precise mechanism of action of Ropinirole as a treatment for Parkinson's disease is unknown, although it is thought to be related to its ability to stimulate dopamine D2 receptors within the caudate-putamen in the brain.

The precise mechanism of action of Ropinirole as a treatment for Restless Legs Syndrome is unknown, although it is thought to be related to its ability to stimulate dopamine receptors.
