    摘要: Amorphous and polymorphic of palonosetron hydrochloride are disclosed that can be characterized by X-ray powder diffraction patterns, thermal properties, purity and methods of manufacture. These forms of palonosetron hydrochloride can be produced from solution or by solid state interconversions. The forms can be used in pharmaceutical formulations: particularly preferred uses of these formulations are in prevention and treatment of nausea and emesis arising from chemotherapy or postoperative side effects. The forms can optionally be used as mixtures of the crystalline and/or amorphous forms.
