Description of intervention(s) / exposure
The interventions being used include the Ropinirole transdermal patch - 8 cm2 transdermal patch, containing 3.84 mg of ropinirole and targeted to deliver 2 mg with each daily application and Requip[Registered Trademark] XL[Trademark] (ropinirole extended release tablets, 2 mg) - 2mg oral tablet.
The study will be conducted in 24 healthy volunteers divided into 2 treatment groups that will be run in parallel (at the same time).
Group 1: will receive a single ropinirole transdermal patch application and a single Requip[Registered Trademark] XL[Trademark] tablet (or vice-versa) separated by a 3-day washout period
Group 2: will receive 5 consecutive daily ropinirole transdermal patches and 5 consecutive daily Requip[Registered Trademark] XL[Trademark] tablets (or vice-versa) separated by a 3-day washout period.

Key exclusion criteria
1. A history or presence of drug or alcohol dependence (excluding caffeine), including subjects who have ever been in a drug rehabilitation program based on medical history.
2. Clinically significant abnormalities as judged by the investigator or designee and determined by physical examination, medical history, 12-lead electrocardiogram (ECG), vital signs, laboratory values including serum kidney and liver function tests.
3. Presence of postural hypotension (determined through examination by the investigator or designee), or recent history of severe dizziness or fainting due to postural hypotension on standing.
4. Subjects with a history of seizures, asthma or obstructive pulmonary disease.
5. Presence or history of a psychiatric disorder, organic brain disorder, or seizure disorder deemed clinically significant by the investigator or designee.
6. Presence or history of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal (including ulcers or gastrointestinal bleeding), endocrine, immunologic, dermatologic, neurologic, oncologic, or psychiatric disease or any other condition, which in the opinion of the investigator would jeopardize the safety of the subject or the validity of the study results.

Query!
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a randomized, open-label study. Within each treatment group, subjects will be randomized in a 1:1 ratio to one of two treatment sequences, as follows:
*Patch, 3-day washout, tablet
*Tablet, 3-day washout, patch
Study drug will not be blinded.
Upon confirmation of eligbility subjects will be assigned (by the PI) the next sequential randomisation number from the randomisation list which is held by the Pharmacist.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation (using a computerised sequence generation) to one of two treatment sequences in a 1:1 ratio.

Summary
Brief summary
The purpose of this research study is to compare the concentration of Ropinirole in the blood after application of the patch to the concentration of Ropinirole in the blood after taking the tablet formulation.
The study will also look at how safe the Ropinirole patch is, as well as how well subjects tolerate the dose delivered transdermally (study drug is absorbed through the skin).
