Polymorphism of Sildenafil: A New Metastable Desolvate

# metadata.dc.description.abstract[].value
A new anhydrous polymorph of the free base of sildenafil and two solvates (acetonitrile and propanenitrile) have been discovered and fully characterized. The new polymorph can be considered a desolvate of the acetonitrile solvate and is related to the most stable form I by morphotropism. The new polymorph can only be obtained by desolvation of the acetonitrile solvate. Thus, this study is a new example of the importance of this multicomponent family of solid forms in the discovery of new polymorphs of active pharmaceutical ingredients.
