Abstract: An improved diluent for the preparation of cisplatin suspensions from a lyophilized powder is provided. The diluent contains a pharmaceutically acceptable nonionic surfactant, which improves the accuracy and homogeneity of the therapeutic formulation. The suspension may be used directly, or may be used in preparing gel formulations for direct injection into a neoplastic lesion or surrounding tissue.

Abstract: Treatment of cellular disorders involving abnormal solid cellular growths involves introduction of cytotoxic reagents dispersed in a physiologically acceptable proteinaceous matrix into the solid cellular growth or area of an existing or removed solid cellular growth. Enhanced effectiveness of the drug is observed, with reduced cytotoxic effects on cells distant from the site of introduction. Other drugs may be included to enhance therapeutic gain and reduce adverse affects to normal tissue.
