Marketing in the lay media and prescriptions of terbinafine in primary care: Dutch cohort study

Abstract
We retrieved all data from the integrated primary care information project—a Dutch research database for general practice—with data from a group of 150 general practitioners.4 To determine rates of prescription of terbinafine and itraconazole for onychomycosis, we counted all prescriptions (first and repeat) written for that specific indication before (1996-9) and during the campaign (2000-2) and divided these by the amount of person time in the population. We also assessed the consultation rate for new onychomycosis.
