A Study to Investigate the Different Modes of (S) Ketamine Administration in Healthy Participants

Inclusion Criteria: * Body Mass Index (BMI) between 20 and 28 kilogram per meter square (kg/m\^2), inclusive (BMI=weight/height\^2) with a minimum weight of 60 kilogram (kg) and a maximum of 100 kg * Participant must be healthy based on clinical laboratory tests performed at screening. If the results of the serum chemistry panel, hematology or urinalysis are outside the normal reference ranges, retesting of an abnormal lab value(s) that may lead to exclusion will be allowed once during the screening phase * Participant must be healthy based on physical and neurological examination, medical history, vital signs, and 12-lead electrocardiogram (ECG) (including QT corrected according to Fridericia's formula \[QTcF\] less than or equal to \[\<=\] 450 milliseconds \[msec\] for males and \<= 470 msec for females) performed at screening. Abnormalities, which are not considered to be of clinical significance by the Investigator, are acceptable. The presence of left bundle branch block (LBBB), atrioventricular (AV) Block (second degree or higher), or a permanent pacemaker or implantable cardioverter defibrillator (ICD) will lead to exclusion * Participant must have systolic blood pressure (SBP) and heart rate (HR) within normal limits at screening and at Day -1: supine SBP of at least 90 millimeters of mercury (mmHg) and maximum 150mmHg, supine diastolic blood pressure (DBP) should be above 50mmHg and below 90mmHg and the HR must be between 45 beats per minute (BPM) and 100 BPM.
