Decision Resources, one of the world's leading research and advisory firms focusing on pharmaceutical and healthcare issues, finds that physicians primarily prescribe Merck's Fosamax and Sanofi-Aventis and Procter & Gamble's Actonel as first-line therapy; to 51.4% and 27.3% of new patients respectively. The main reasons surveyed physicians choose Fosamax over Actonel are familiarity (mentioned by 54% of primary care physicians and 65 percent of gynecologists) and improvements in bone mass density (cited by 51 percent of primary care physicians and 50 percent of gynecologists).

The report entitled Treatment Algorithms in Osteoporosis finds that Roche and GlaxoSmithKline's Boniva is the most commonly prescribed second-line agent, capturing 27.3 percent of second-line patients.

"Surveyed physicians say the primary reasons for prescribing oral Boniva over Fosamax are the ease of its administration (including less frequent dosing) and a lower frequency of gastrointestinal side effects, which are stated by 80 percent and 53 percent of physicians, respectively," said Jeremy Goldman, M.D., analyst at Decision Resources.
