Notes: Prostaglandin F2β (PGF2β) (tromethamine salt) is a derivative of PGF2β (Item No. 16410) with increased water solubility. PGF2β is the 9β-hydroxy stereoisomer of PGF2α (Item No. 16010). It is much less active than PGF2α in antifertility and bronchoconstrictor activities.{1925,2121,633} PGF2β exhibits bronchodilating activity in guinea pigs and cats and antagonizes the bronchoconstrictor activity of PGF2α.{633}
