Brief summary
The purpose of this study is to evaluate the pharmacokinetics of intranasally administered esketamine in healthy Han Chinese, Korean, Japanese, and Caucasian participants and to evaluate the effects of rifampin on the pharmacokinetics of intranasally administered esketamine in healthy Caucasian participants.

Inclusion criteria
* For Cohort 1: healthy Han Chinese participants 20 to 55 years of age, inclusive, who have resided outside of China for no more than 10 years and have parents and maternal and paternal grandparents who are of Han Chinese ethnicity For Cohort 2: healthy Korean participants 20 to 55 years of age, inclusive, who have resided outside of Korea for no more than 10 years and have parents and maternal and paternal grandparents who are of Korean ethnicity For Cohort 3: healthy Japanese participants 20 to 55 years of age, inclusive, who have resided outside of Japan for no more than 10 years and have parents and maternal and paternal grandparents who are of Japanese ethnicity For Cohort 4: healthy Caucasian participants 20 to 55 years of age, inclusive Participants must be within +/-7 years and +/-20 percent (%) of the combined mean age and mean body weight at Screening, respectively, of Cohort 1, Cohort 2, and Cohort 3 * Body mass index (BMI; weight \[kilogram\]/height\^2 \[m\]\^2) between 18 and 30 kilogram per meter square (kg/m\^2), inclusive, and a body weight not less than 47 kilogram (kg) * If a woman, must have a negative serum beta-human chorionic gonadotropin (beta-hCG) pregnancy test at Screening * If a woman, must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for 1 month after receiving the last dose of study drug * Creatinine clearance more than equal to (\>=)80 milliliters per minute (mL/min) based on Cockroft-Gault equation

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate Constant (Lambda[z]) | Up to Day 2 | Lambda(z) is first-order rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. |
| Maximum Observed Plasma Concentration (Cmax) | Up to Day 2 | The Cmax is the maximum observed plasma concentration. |
| Time to Reach Maximum Observed Plasma Concentration (Tmax) | Up to Day 2 | The Tmax is defined as actual sampling time to reach maximum observed plasma concentration. |
| Time to Last Observed Quantifiable Plasma Concentration (Tlast) | Up to Day 2 | The Tlast is the time to last observed quantifiable plasma concentration. |
| Area Under the Plasma Concentration-time Curve From Time 0 to 12 Hours (AUC12h) | Up to Day 2 | The (AUC12h) is the area under the plasma concentration-time curve from time 0 to 12 hours Post-dose. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Time of the Last Quantifiable Concentration AUC(0-last) | Up to Day 2 | The AUC (0-last) is the area under the plasma concentration-time curve from time 0 to time of the last quantifiable concentration. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) | Up to Day 2 | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(0-last) and C(0-last)/lambda(z), wherein AUC(0-last) is the area under the plasma concentration-time curve from time 0 to time of the last quantifiable concentrations; C(0-last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant. |
| Elimination Half-life (t1/2) | Up to Day 2 | Elimination half-life (t \[1/2\]) is associated with the terminal slope (lambda \[z\]) of the semi logarithmic drug concentration-time curve, calculated as 0.693/lambda(z). |
