WebPolymorphism and pseudomorphism are very common amongst drugs and are responsible for differences in many properties . Generally, polymorphism is considered to be of two types, viz. monotropic systems and enantiotropic systems. In the former type, only one polymorphic form is stable at the temperatures below the melting point of the solid drug.
