"Bayer Schering Pharma is looking forward to progressing to Phase III trials with our novel patch. It will be the smallest, lowest dosed and the only transparent patch for female contraception on the market," said Phil Smits, head of women's healthcare at Bayer Schering Pharma. "We are optimistic that these attributes will make it an attractive option for women seeking alternative routes of hormonal contraception."

The patch will be applied once a week, i.e. three patches per cycle (for 21 days), then one week off. Bayer says the simple handling will make the product convenient to use, and therefore, a good compliance from the user is anticipated.
