Cloprostenol (sodium salt) is a more water solute, crystalline form of cloprostenol than the free acid. Cloprostenol is a synthetic analog of prostaglandin F (PGF). It is 200 times and 100 times more potent than PGF in terminating pregnancy in hamsters and rats, respectively, without the side effects associated with PGF.1 The subcutaneous dose required for interrupting early pregnancy is species dependent, requiring approximately 1.25 µg/kg and 270 µg/kg in hamsters and rats, respectively.1 Cloprostenol is also a potent inhibitor of rat adipose precursor differentiation in primary cultures with an IC50 of 3 x 10−12 M.2
