I Am A Graduate Degree Microbiologist Retired From The Pharmaceutical

I am a graduate degree microbiologist retired from the pharmaceutical industry . I have RA and am on a monoclonal antibody, Enbrele. I recently read that biological clocks play an
important role possibly when the medication is taken and that
two clocks play an important role in the liver with when a human takes Tylenol. Is there any info on medication, b. clocks, and R. arthritis.
