Summary:

      The purpose of this study is to look at how much lasmiditan, study drug, gets into the blood
      stream and how long it takes the body to get rid of it.

      When drugs are taken together, one or all of the drugs used in combination may be affected.
      This study will also evaluate the concentrations in the blood of a probe drug cocktail taken
      alone and in combination with lasmiditan. Information about any side effects that may occur
      will also be collected.

      The study has two parts. Participants will only enroll in one part. This study will last
      about 25 days for group 1 and 22 days for group 2, not including screening. Screening is
      required within 28 days prior to the start of the study.

      This study is for research purposes only and is not intended to treat any medical condition.
