7. Has clinical laboratory evaluations (including clinical chemistry, hematology and complete urinalysis) within the reference range for the testing laboratory, unless the results are deemed not to be clinically significant (CS) by the investigator at screening and Day -1 (Check-in) of Period 1.

Exclusion Criteria

1. Has received any investigational compound within 3 months prior to the first dose of study medication.
2. Has received roflumilast, donepezil, or scopolamine in a previous clinical study or as a therapeutic agent.
3. Is an immediate family member, study site employee, or in a dependant relationship with a study site employee who is involved in the conduct of this study (eg, spouse, parent, child, sibling) or may consent under duress.
4. Has uncontrolled, clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, gastrointestinal, or endocrine disease or other abnormality which may impact the ability of the participant to participate or potentially confound the study results.
5. Contraindications to scopolamine: hypersensitivity to scopolamine and other belladonna alkaloids, and/or any component of the formulation, serious allergic reactions, wide and narrow angle glaucoma, gastrointestinal motility disorders (such as constipation, gastroesophageal reflux disease, irritable bowel syndrome), benign prostatic hyperplasia with urinary retention, asthma, chronic obstructive pulmonary disease (COPD), seizures, coronary artery disease, hypertension, and congestive heart failure.
6. Participants with existing psychiatric disease/condition including psychosis, affective disorder, anxiety disorder, borderline state and personality disorder according to the criteria in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, as assessed by the Mini International Neuropsychiatric Interview (MINI) or acute psychiatric episode within 6 months of Screening.
7. Has a known hypersensitivity to any component of the formulation of roflumilast, donepezil, scopolamine, or related compounds.
8. Has a positive urine drug result for drugs of abuse at Screening or Day -1 (Check-in) of each Period.
9. Has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse within 1 year prior to the screening visit or is unwilling to agree to abstain from drug use or excessive alcohol use throughout the study.

11. Intends to donate sperm during the course of this study or for 12 weeks thereafter.
12. Any finding in the participant’s medical history, physical examination, or safety laboratory tests giving reasonable suspicion of a disease that would contraindicate taking roflumilast, donepezil, scopolamine, or a similar drug in the same class, or that might interfere with the conduct of the study. This includes, but is not limited to, peptic ulcer disease, seizure disorders, and cardiac arrhythmias.
13. Has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs (ie, a history of malabsorption, esophageal reflux, peptic ulcer disease, or erosive esophagitis, frequent [more than once per week] occurrence of heartburn.

17. Has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 28 days prior to Check-in on Day -1 (Check-in of Period 1).
18. Cotinine test is positive at Screening or Check-in (Day -1 of each Period).
19. Has poor peripheral venous access.
20. Has donated or lost 450 mL or more of his or her blood volume (including plasmapheresis), or had a transfusion of any blood product within 3 months prior to Day 1 of Period 1.
21. Has a Screening or Day -1 (Check-in) of Period 1 abnormal (clinically significant) electrocardiogram (ECG). Entry of any participant with an abnormal (not clinically significant) ECG must be approved, and documented by signature by the principal investigator or qualified delegate.
22. Has abnormal Screening or Day -1 (Check-in) of Period 1 laboratory values that suggest a clinically significant underlying disease or participant with the following lab abnormalities: alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) >1.5 the upper limits of normal.
23. Has a current diagnosis or history of glaucoma or had a first-degree relative diagnosed with glaucoma.
