Clinical rationale There is a clinical need for the availability of emergency contraception because of the health and social costs of unplanned pregnancy. Unplanned pregnancy may result from contraception failure or situations where intercourse is not anticipated or has been coerced. Abortion is a less acceptable alternative to emergency contraception. High dose oestrogen progestin regimens, and more recently levonorgestrel, have been previously used as emergency contraception. However, with levonorgestrel reported pregnancy rates rise from approximately 1.5 to 2.6%, respectively, for intake 0 to 24 h as compared to intake 48 to 72 h after intercourse. Hence, ulipristal offers the potential for emergency contraception that can be taken within 5 days of UPI. 2. Contents of the clinical dossier 2.1.
