Figure 1: Mean Norelgestromin Serum Concentrations (ng/mL) in Healthy Female Volunteers Following Application of ORTHO EVRAŽ on the Buttock for Three Consecutive Cycles (Dotted horizontal lines indicate the
reference range. Dotted vertical arrow indicates time of patch removal.)

Figure 2: Mean Ethinyl Estradiol Serum Concentrations (pg/mL) in Healthy Female Volunteers Following Application of ORTHO EVRAŽ on the Buttock for Three Consecutive Cycles (Dotted horizontal lines indicate the reference range. Dotted vertical arrow indicates time of patch removal.)
Results from a study of consecutive ORTHO EVRAŽ wear for 7 days and 10 days indicated that serum concentrations of norelgestromin and EE dropped slightly during the first 6 hours after the patch replacement, still
stayed within the reference range and recovered within 12 hours. Target Css of norelgestromin and EE were maintained during 2 days of extended wear of ORTHO EVRAŽ.
