WASHINGTON — Osteoporosis patients demonstrate greater compliance with weekly bisphosphonate therapy than with daily medication, but the numbers are still suboptimal, Deborah T. Gold, Ph.D., reported in a poster she presented at an international symposium sponsored by the National Osteoporosis Foundation.
Patients often resist taking bisphosphonates because of their inconvenient and complex dosing procedures, explained Dr. Gold of Duke University Medical Center, Durham, N.C.
Dr. Gold and her associates analyzed data on 214,060 women aged 50 years and older who received bisphosphonate therapy; the information had been collected for two health claims and retail pharmacy databases. Overall, weekly doses led to improved compliance after 1 year, compared with daily doses (44%–55% vs. 32%–40%), but 42%–67% of the patients on the weekly regimen had discontinued the medication within a year.
In addition, the level of compliance with either a weekly or daily dose was often too low to benefit many patients. Sufficient compliance was defined as a “medication possession ratio” of at least 80%. At most, only 53% of patients who received weekly medication were deemed compliant enough to derive antifracture benefits from it, which was still significantly better than the up to 40% rate of sufficient compliance among patients who received daily medication. Dr. Gold serves as a consultant for multiple pharmaceutical companies.
