E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Study design according to CPMP/EWP/QWP/1401/98 and CPMP/EWP/280/96. Using an open-label, three-treatment, dose-ranging, single-period, randomized, single and multiple-dose design, three treatments in three parallel treatment groups with 16 subjects each will be investigated in this study. The subjects will be randomly assigned to one of the treatment groups.

E.4 | Principal exclusion criteria |
a) Evidence in the subject's medical history or in the medical examination of any clinically significant hepatic, renal, gastrointestinal, cardiovascular, pulmonary, haematological or other significant acute or chronic abnormalities which might influence either the safety of the subject or the absorption, distribution, metabolism or excretion of the active agent under investigation. b) Pregnancy (positive pregnancy test) or lactation. c) Skin disease that might affect the oxybutynin absorption. d) Large abdominal scars, tattoos, excessive hair in the application area. e) The subject has a history of renal or hepatic dysfunction. f) Relevant cardiovascular disorders, e.g. coronary disease, heart insufficiency, hypertension (sitting blood pressure at screening >150/92 mmHg), tachyarrhythmia. g) The subject has a bladder obstruction, e.g. prostate hyperplasia, urethral strictures. h) History or evidence of stenose of urinary or gastrointestinal tract; toxic megacolon, ileus, hiatus hernia, reflux oesophagitis, colon ulcera, intestinal atonia. i) History or evidence of glaucoma (as screened by an ophthalmologist with an intraocular pressure >22mmHg in either eye). j) History of cerebral sclerosis; myasthenia, autonomous neuropathy. k) Hypersensitivity to drugs, atopic eczema or allergic bronchial asthma. l) Clinically significant laboratory test results outside the reference values as laid down by the study centre, which may be an evidence of disease. Positive result of HIV1/2, HCV antibody or HBs antigen testing. m) Regular use of any medication (except for hormonal contraception) within four weeks prior to commencement of the study (self-medication or prescription). n) Single use of any medication (including OTC) that are not expressively permitted within two weeks prior to start of the study. o) Abuse of alcohol (equivalent to more than 35 g ethanol per day) or caffeine (equivalent to more than 750 mg per day) or tobacco (equivalent to more than 10 cigarettes a day). p) Drug addiction, positive drug screening in urine. q) Participation in a clinical investigation or blood donation of more than 250 ml within the past eight weeks or blood donation of less than 250 ml within the past 4 weeks. r) Subjects who are known or suspected not to comply with the study directives not to be reliable or trustworthy not to be capable of understanding and evaluating the information given to them as part of the formal information policy (informed consent), in particular regarding the risks and discomfort to which they would agree to be exposed to be in such a precarious financial situation that they no longer weigh up the possible risks of their participation and the unpleasantness they may be involved in.
