Title: Radioimmuno conjugates, preparation method thereof and site directed radio therapy using the same
Inventor: GEERLINGS MAURITS WILLEM
IPC: G01N33/533
Filed: 1993-07-26
Granted: 2001-11-22
Abstract: PURPOSE: Provided is a site directed radio therapy. Also, provided are a method for production of radioimmuno conjugates and an apparatus for radioimmuno therapy. The method, conjugates and apparatus can be practicalized without the need for radioactive shielding and/or airtight facilities. Without these restrictions a simple and efficient means of therapy at the bed-side of the patient is provided. CONSTITUTION: A radioimmuno conjugate is characteristically prepared by coupling a targeting moiety to bismuth-213 radioisotope and used for the treatment of cancer metastasis, cell carcinoma and autoimmune diseases.

Title: Agglomerated hydrophilic complex with multi-phase release characteristics
Inventor: BAICHWAL ANAND R
IPC: A61K47/36
Filed: 1993-07-30
Granted: 2002-11-18
Abstract: PURPOSE: Provided is a formulation, that is an agglomerated hydrophilic complex formulation capable of providing multi-phasic or bi-phasic controlled release of a therapeutically active medicament. CONSTITUTION: The formulation comprises an effective amount of a medicament to render a therapeutic effect; a controlled-release excipient comprising a heteropolysaccharide gum and a homopolysaccharide gum capable of cross-linking the heteropolysaccharide gum in the presence of aqueous solutions, such that the ratio of the heteropolysaccharide gum to the homopolysaccharide gum is from about 1:3 to about 3:1; an inert pharmaceutical diluent selected from the group consisting of monosaccharide, a disaccharide, a polyhydric alcohol, and mixtures thereof, wherein the ratio of the inert diluent to the heterodisperse gum matrix is from about 3:7 to about 7:3; and 4-10 wt% of a pharmaceutically acceptable surfactant or wetting agent to stimulate a multi-phasic release of the medicament when the dosage form is exposed to aqueous fluids.
