"Gedeon Richter is the perfect partner for Pantarhei Bioscience to bring this new oral contraceptive concept Androgen Restored Contraception (ARC) to the market. The extensive and long term experience of Richter in producing and selling hormonal products guarantees for Pantarhei a successful future for this first choice new contraceptive pill," stated Herjan Coelingh Bennink, President of Pantarhei Bioscience and inventor of the ARC concept.


About the combined ARC oral contraceptive

The product under development is a combined oral contraceptive containing 30 µg ethinyl estradiol, 150 µg levonorgestrel and 50 mg DHEA in each tablet. ARC is a novel concept of oral contraception developed and patent protected by Pantarhei with the aim to restore sexual function with a special focus on sexual desire and arousal and to prevent mood disturbances. This is achieved by adding DHEA to the contraceptive pill. DHEA is a natural human adrenal androgen that is metabolised partially to testosterone after oral intake, which hormone level is suppressed when fertile women use a contraceptive pill. By adding 50 mg DHEA to the pill, the testosterone levels are normalised. The longstanding safety track record of DHEA in the human at the low dose level used in this application implies safety when DHEA is added to the pill.
