Autor: Ivo B. Rietveld, Hassan Allouchi, René Céolin
Publikováno v: Annales Pharmaceutiques Françaises. 78:303-309
The pressure-temperature phase diagram of the dimorphism of the contraceptive drug gestodene is constructed using the temperature and enthalpy of fusion of form I (469.5K, 107Jg-1), and those of the endothermic transition from form II to form I (311K
