* A female participant, except if postmenopausal, must have a negative serum beta human chorionic gonadotropin (beta- hCG) pregnancy test at screening, and a negative urine pregnancy test on Day 1 in each treatment period
* Participant must be able to taste and smell normally, to their own opinion. Participants who have an impaired sense of taste and/or smell due to any conditions such as allergic rhinitis, common cold, or sinusitis are not eligible to take part in the study
Exclusion Criteria:
