The Therapeutics Initiative's objectives are unbiased review and dissemination of therapeutic evidence. Our recommendations are intended to apply to most patients; exceptional patients require exceptional approaches. We are committed to evaluate the effectiveness of our educational activities using the Pharmacare/PharmaNet databases without identifying individual physicians, pharmacies or patients. The Therapeutics Initiative is funded through a 5-year grant to the University of British Columbia from the Government of British Columbia, Ministry of Health and Ministry Responsible for Seniors.

Therapeutics Letter, issue 26, September - October 1998

NEW DRUGS IV

  • Donepezil (Aricept®)
  • Levofloxacin (Levaquin®)
  • Pantoprazole (Pantoloc®)
  • Quetiapine (Seroquel®)

  • Donepezil (Aricept®)


    Levofloxacin (Levaquin®)

    Levofloxacin is a fluoroquinolone antibiotic, which is the levo-rotatory stereoisomer of ofloxacin (Floxin®). Antibacterial activity resides predominantly in the levo-rotatory isomer, but levofloxacin kinetics are similar to ofloxacin.(4)


    Pantoprazole (Pantoloc®)


    Quetiapine (Seroquel®)
