Progesterone carboxymethyloxime, or progesterone 3-(O-carboxymethyl)oxime (P4-3-CMO), is a progestin which was never marketed. It is an oral prodrug of progesterone with improved pharmacokinetic properties. The compound was developed in an attempt to address the poor oral pharmacokinetics of progesterone, including its very low bioavailability and short biological half-life. These properties of progesterone are thought to be caused by its low water solubility and high metabolic clearance rate due to rapid degradation in the intestines and liver. Drugs with low aqueous solubility are not absorbed well in the intestines because their dissolution in water is limited.
