Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the single-dose pharmacokinetics of atropine gel formulation after topical administration in the oral cavity of healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a single-dose, single-center, open-label study of the pharmacokinetics of atropine gel (0.01% w/w) after topical oral administration in healthy adults. Study participants will be recruited by Drs. Murphy, Darro, and Yellepeddi at the Center for Clinical and Translation Science (CCTS), University of Utah. Participants who meet eligibility criteria will be recruited in the study after signing informed consent. Each of the 10 participants will receive 1 gram of atropine gel (0.01% w/w) containing 0.1 mg atropine via self-administration of gel into the oral cavity. Dr. Yellepeddi is a licensed pharmacist in the State of Utah and will train subjects in the administration of atropine gel in the oral cavity. A series of timed blood samples (0, 5, 10, 15, 30, 60 minutes, and 2, 4, 6, 8, and 24 hours, 7 mL each time point) will be collected in commercial tubes, and plasma will be separated by centrifugation. The plasma samples will be stored frozen until further analysis by the Center for Human Toxicology (CHT), University of Utah.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Provide written informed consent and authorization.
2. Study participants must be able to complete consent, and all study evaluations written in the English language.

Exclusion Criteria

1. Female subjects who are pregnant or nursing at the time of screening
2. Chemotherapy or radiotherapy treatment within the last three months
3. Severe renal impairment defined as estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m2 calculated using the CKD-EPI creatinine equation:

Where,
1. k=0.7 if female
2. k=0.9 if male
3. α=-0.329 if female
4. α=-0.411 if male
5. min=The minimum of Scr/k or 1

1. Bilirubin \> 3 x upper limit of normal (ULN). \[ULN for bilirubin = 1.4 mg/dL\]
2. Alanine aminotransferase (ALT) or Aspartate aminotransferase (AST) \> 3 x ULN values used by the laboratory performing the test. \[ULN for AST = 40 U/L, ULN for ALT = 60 U/L\]
3. Alkaline phosphatase (ALP) \> 3 x ULN \[ULN for ALP = 126 U/L)
5. Deforming lesions of the oral cavity
6. Previous head and/or neck radiotherapy

8. Patients with heart conditions such as congenital heart disease, heart failure, coronary heart disease, myocardial infarction, and arrhythmia
9. Patients with acute glaucoma that may be exacerbated with atropine administration.
10. Patients with partial pyloric stenosis or other diseases related to gastrointestinal obstruction.
11. Patients diagnosed with urinary retention
12. Treatment with any other investigational drug during the 30 days prior to enrollment into the study
13. Patients receiving anticholinergic medications at baseline.
14. Patients who are receiving immunosuppression
15. Patients who are actively being treated for an infection
16. Patients with a history of salivary gland obstruction or stones
17. Patients with a history of chronic lung disease or chronic obstructive pulmonary disease (COPD)
