Parkinson's Disease Patient Study On Absorption, Distribution, Metabolism And Excretion Of Ropinirole
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This study in PD patients is designed to assess the affect food has on the absorption, distribution, metabolism and excretion of ropinirole (by dosing some patients in the fasted state and other patients following a high-fat breakfast), and to assess the difference in absorption, distribution, metabolism and excretion of ropinirole if patients are given three 4mg ropinirole tablets versus one 12mg tablet.
An Open Label, Repeat Dose, Dose Escalation Study Conducted in Parkinson's Disease Patients to Characterize the Pharmacokinetics and Effect of Food on Ropinirole Prolonged Release (PR/CR) 12mg Tablets.

Positive alcohol test result and / or urine test for undeclared drugs
Recent history of moderate to severe dizziness, syncope, or orthostatic hypotension
Patients with a lying/sitting diastolic blood pressure =110mmHg or =50mmHg or a systolic blood pressure =180mmHg or =90mmHg
History of any dopaminergic treatment (other than ropinirole IR and L-dopa) within 2 weeks prior to first dose.
Withdrawal, introduction, or change in dose of hormone replacement therapy and/or any drug known to substantially inhibit CYP1A2 or induce CYP1A2

Blood donation or significant blood loss less than 90 days before Day 1 of the current study.
Definite or suspected personal history, or family history, of adverse reactions or hypersensitivity to ropinirole or to drugs with a similar chemical structure.
Use of any investigational drug (with the exception of ropinirole PR/CR) within 30 days or 5 half lives (whichever is longer) before the start of dosing with study medication.
Patients who have received over-the-counter (OTC) medicine within 48 h before the first dose of study drug.
Recent history, or suspicion, of drug dependence or abuse of alcohol
Significant concern, or likelihood, that the patient will drop out of the study prematurely, will require new or prohibited concomitant medications during the study period, or will not be compliant with study procedures.
Women who are pregnant or breast-feeding.
Female patient is currently either of:
Non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal or any female who is surgically sterilized (via documented hysterectomy or bilateral tubal ligation).
(For purposes of this study, postmenopausal is defined as one year without menses) OR
child-bearing potential, has a negative urine/serum pregnancy test at the Screening Visit (prior to investigational product administration), and agrees to use acceptable contraception from one month prior to study Day 1 until one month after completion of the study (ie. one month after the follow-up visit). All hormonal birth control must have been administered for at least one monthly cycle prior to the Screening Visit. GSK acceptable contraception methods, when used consistently and in accordance with both the product label and the instructions of a physician, are as follows:
sterilization of patient's male partner prior to female patient's entry into study
oral contraceptive (either combined or progestogen only)
any intra-uterine device with a documented failure rate of less than 1% per year
systemic contraception (eg. norplant system)
double barrier method if comprised of a spermicide with either a condom or diaphragm
