Description

STABLE PHARMACEUTICAL COMPOSITION OF IMATINIB
Field of the Invention
The present invention relates to a compressed film-coated tablet comprising imatinib its pharmaceutically acceptable salts there of in an amount of more than 80% based on the total weight of the finished dosage form and a film coating on said tablet core is applied in an amount of 1 to 2 % w/w of the tablet.
Background of the Invention
Imatinib mesylate is chemically 4-[(4-Methyl l-piperazinyl)methyl]-N-[4- methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-phenyl]benzamide methanesulfonate and is used to treat chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs) and other cancers. In this document the term "imatinib" will refer to the mono methane sulfonate salt of imatinib unless otherwise specified.
Imatinib mesylate is a protein-tyrosine kinase inhibitor that inhibits the bcr-abl tyrosine kinase, the constitutive abnormal tyrosine kinase created by the Philadelphia chromosome abnormality in CML. Imatinib inhibits proliferation and induces apoptosis in bcr-abl positive cell lines as well as fresh leukemic cells from Philadelphia chromosome positive chronic myeloid leukemia. Imatinib inhibits colony formation in assays using ex vivo peripheral blood and bone marrow samples from CML patients.
US patent 6894051 discloses the novel crystalline form of the mono methane sulfonic acid addition salt of imatinib and its preparation process and designated the form as β-crystalline form.
US patent 6958335 describes the use of imatinib or a pharmaceutically acceptable salt thereof for the manufacture of pharmaceutical compositions for use in the treatment of gastrointestinal stromal tumours.
US patent 7544799 discloses a particular form of methane sulfonic acid addition salt of imatinib.
PCT application WO 03/090720 describes a tablet comprising a pharmacologically effective amount of imatinib or a pharmaceutically acceptable salt thereof in an amount from about 30% to 80% in weight of the active moiety based on the total weight of tablet and pharmaceutically acceptable excipient.
PCT application WO 01/47507 describes a pharmaceutical composition comprising imatinib mesylate in an amount of 22% W/W.
US patent application US 2009/0087489 describes a pharmaceutical composition, preferably tablet, containing about 23-29% W/W of imatinib mesylate which were prepared using dry granulation or direct compaction.
As it is a high drug loaded composition, the present inventors have come across several problems in preparing the tablets of imatinib with such a low quantity of excipients. Thus, still there is a need for commercially acceptable high drug load compositions of imatinib.
Surprisingly, the present inventors have obtained a film coated tablet with high drug load of imatinib or pharmaceutical acceptable salts thereof and the tablet is film coated with opadry brown/yellow having poly vinyl alcohol as main ingredient.
