3. Body Mass Index (BMI): 18.5-30 kg/m² inclusive
4. Vital signs: systolic blood pressure (SBP) 100-139 mmHg, diastolic blood pressure (DBP) 50-89 mmHg, heart rate (HR) 50-90 bpm, measured after 5 min at rest in the sitting position
5. Full comprehension: the ability to comprehend the full nature and purpose of the study, including possible risks and side effects; ability to co-operate with the investigator and to comply with the requirements of the entire study
6. Contraception and fertility (women only): women of childbearing potential must be using at least one of the following reliable methods of contraception:
6.1. Hormonal oral, implantable, intrauterine device [IUD], transdermal or injectable contraceptives for at least 2 months before the screening visit
6.2. A non-hormonal IUD or female condom with spermicide or contraceptive sponge with spermicide or diaphragm with spermicide or cervical cap with spermicide for at least 2 months before the screening visit
6.3. A male sexual partner who agrees to use a male condom with spermicide
6.4. A sterile sexual partner
Women of non-childbearing potential or in post-menopausal status for at least 1 year will be admitted. For all women, pregnancy test result must be negative at screening and day -1 of each study period

Exclusion Criteria

1. Electrocardiogram (12-lead, supine position): clinically significant abnormalities
2. Physical findings: clinically significant abnormal physical findings which could interfere with the objectives of the study and which the investigator considers may affect the outcome of the study
3. Laboratory analyses: clinically significant abnormal laboratory values indicative of physical illness
4. Application site: diseased-skin, skin wounds, open injuries or tattoos at the application site
5. Allergy: ascertained or presumptive hypersensitivity to the active principle and/or formulations' ingredients; history of anaphylaxis to drugs or allergic reactions in general, which the investigator considers may affect the outcome of the study
6. Diseases: significant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, haematological, endocrine or neurological diseases that may interfere with the aim of the study
7. Medications: medications, including over the counter (OTC) medications and herbal remedies for 2 weeks before the start of the study. Hormonal contraceptives for females will be allowed
8. Investigative drug studies: participation in the evaluation of any investigational product for 3 months before this study. The 3-month interval is calculated as the time between the first calendar day of the month that follows the last visit of the previous study and the first day of the present study
9. Blood donation (population subgroup for PK analysis only): blood donations for 3 months before this study
10. Drug, alcohol, caffeine, tobacco: history of drug, alcohol (>1 drink/day for females and >2 drinks/day for males, defined according to the USDA Dietary Guidelines 2015-2020), or caffeine abuse (>5 cups coffee/tea/day) or tobacco abuse (10 or more cigarettes/day)
11. Drug test: positive result at the drug test at screening or day -1

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
ocal tolerability is assessed as an adverse drug reaction at the application site at pre-application (on Day 1 before the first plaster application) and on Days 2 and 3 immediately after plaster removal, using a 4-grade scale to score application site erythema, dryness, swelling and exfoliation. Plaster application will be performed every day at 8:00 ± 1 h.
