Abstract: ORAL LIQUID FORMULATIONS OF ABIRATERONE Abstract The present invention relates to liquid formulations of Abiraterone intended for oral administration. The invention provides suspension and emulsion formulations of Abiraterone and process of preparing such formulations. Further, the invention relates to Nanoemulsion formulations of Abiraterone comprising Abiraterone, oil phase, aqueous phase, one or more emulsifying agents and optionally other pharmaceutical excipients, wherein the concentration of excipients are optimized for better stability.
