The chemical and physical properties of the active pharmaceutical ingredients (API) on solid-state form can be affected by polymorphism effect. This effect can have a significant influence on the apparent solubility of the drug substance. Polymorphic forms of API differ in their internal solid-state structure, these compounds show a different crystallographic arrangements and different H-bonds self-arrangements [1,2]. The consequences of this effect in a drug substance which may exists in various polymorphic forms are change aqueous solubilities and dissolution rates [3].
