Thermal Analysis of Pharmaceuticals
3.2.1 The Melting of Enantiotropic and Monotropic Polymorphs If a drug has two
enantiotropic polymorphic forms, either may be stable depending on the
temperature at a given pressure, whereas for monotropic polymorphism only one
form is ...

Water-Insoluble Drug Formulation
Giron (1995) and Haleblian and McCrone (1969) have described the different
phase diagrams resulting from monotropic and enantiotropic polymorphs. If the
free energies of two polymorphs (or a measure of the free energy such as vapor ...

Enantiotropic System C, Monotropic System Temperature Temperature tiotropic
system on the left, at constant pressure, there are three solubility versus
temperature curves: Form II is the lowest, Form I is the next higher, and the
melting curve ...

Handbook of Modern Pharmaceutical Analysis
The interconversion of such crystal forms is classified as being either
enantiotropic or monotropic, according to whether the transformation of one
modification into the other is reversible or not. Enantiotropic modifications
interchange reversibly ...

Thus, the best definition for monotropic phases is that they are mesophases that
occur below the melting temperature', not the ones that occur only on cooling:

Modern Instrumental Analysis
When a solid system undergoing a thermal change in phase exhibits a reversible
transition point at some temperature below the melting points of either of the
polymorphic forms of the solid, the system is described as exhibiting
enantiotropic ...
