Brief summary
This is an open-label, three-part study to assess the pharmacokinetics (PK) and pharmacodynamics (PD) of epinephrine administered as a single dose of L-dipivefrin (IN-001) sublingual spray or drop in healthy adults. For all parts of the study, participants will undergo at least 10 hours of fasting prior to dosing. Part 1 of the study focuses on IN-001 dose/formulation exploration in a small number of participants (N=6); Part 2 of the study involving up to 12 participants will test a dose selected from Part 1 delivered as both a sublingual spray and a sublingual drop. In Part 3, one delivery method will be tested. Total number of participants is 30.

Eligibility
Inclusion criteria
* To participate in this trial, volunteers must meet all of the inclusion criteria listed below: 1. Age \> 18 years of age and \< 45 years of age. 2. Women of childbearing potential or men with childbearing potential partners must agree that the participant and/or their partner will use the following effective methods of birth control from screening visit until 14 days after the last dose of study drug: 1. Abstinence 2. Hormonal contraceptives for at least one month prior to Screening 3. Double barrier (e.g., diaphragm with spermicide, condom with spermicide) 4. Intrauterine device (IUD) 5. Surgically sterile (e.g., bilateral tubal ligation, total or partial hysterectomy, or bilateral oophorectomy) * Note: Females will be considered post-menopausal if they * are at least 45 years of age with amenorrhea for at least one year, or * received bilateral oophorectomy with or without a hysterectomy. 3. BMI \> 18.50 and \< 29.90 kg/m2 (using formula BMI = weight (kg)/height (m2). 4. All clinical laboratory test results (e.g., hematology, chemistry, urinalysis) are within normal limits or considered not clinically significant by Investigator. 5. Serum pseudocholinesterase activity is within normal limits or considered not clinically significant by Investigator. 6. Physical examination (excluding genital and rectal exams) is normal or considered not clinically significant by Investigator. 7. Vital signs measurements (pulse rate, blood pressure, temperature, and respiratory rate) are normal or considered not clinically significant by Investigator, while seated or semi-recumbent and after 5 minutes of rest. Normal vital sign ranges are listed below: 1. Systolic blood pressure: 90 - 140 mmHg 2. Diastolic blood pressure: 50 - 90 mmHg 3. Pulse rate: 45 - 100 beats per minute (bpm) 4. Oral body temperature: 35.0°C - 37.5°C 8. 12-lead electrocardiogram (ECG) is normal or considered not clinically significant by Investigator. 9. Participants must agree to not consume caffeine and/or xanthine containing products (i.e., coffee, tea, chocolate, caffeine-containing sodas, etc.), grapefruit and grapefruit containing products, and poppyseed containing foods within 48 hours prior to Period 1 check-in. 10. Able to comply with study procedures, in the opinion of the Investigator(s). 11. Willing to provide written consent for screening procedures. Legally authorized representatives will not be allowed to sign on behalf of participants in this trial.
