Popis: In a clinical trial involving once-weekly oral administration of 2.5 mg of R 2323 (13-ethyl-17-hydroxy-18, 19-dinor-17α-pregna-4, 9, 11-trien-20-yn-3-one) to 181 women over 2971 months of use, a drug-failure rate of 4.4% and a patient failure rate of 2.8% were recorded. No side effects, other than slight menstrual disturbances, were observed. The mechanisms underlying the efficacy of treatment with this compound, known for its weak progestin and marked anti-progesterone properties, are discussed.
