Abstract

Official abstract text for this publication.

The present invention relates to the use of octenyl succinate starch, in particular sodium octenyl succinate starch as a binder in wet granulation, in particular for pharmaceutical solid dosage form and the granule obtainable by the method thereof.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A method for preparing granules comprising one or several substances by wet granulation comprising the steps of: a) wetting powder of substances with a granulation liquid in presence of a binder consisting of partially hydrolyzed waxy octenyl succinate starch having a weight average molecular weight from 10 4 to 10 6 g/mol in order to obtain granules and, b) drying said granules, wherein said partially hydrolyzed waxy octenyl succinate starch is a waxy octenyl succinate that as been partially hydrolyzed with an alpha-amylase. 2 . The method of claim 1 wherein the step a) comprises the steps of: a1) mixing substance powder with powder of said binder, a2) wetting said powder mixture of step a1) with a granulation liquid consisting of a solvent. 3 . The method of claim 1 wherein said substances powder in step a) is wetted with a granulation liquid which comprises said binder. 4 . The method of claim 3 wherein said granulation liquid comprising said binder is sprayed onto the substances powder. 5 . The method of claim 3 wherein said granulation liquid comprising said binder has a Brookfield viscosity from 10 to 10 3 mPa·s. as measured at 25° C. using a Brookfield Digital Viscometer DV-I at 100 rpm. 6 . The method according to claim 1 further comprising a step c) of milling the dried granules. 7 . The method according to claim 1 wherein said partially hydrolyzed octenyl succinate starch is a partially hydrolyzed waxy maize octenyl succinate starch. 8 . The method according to claim 1 wherein said partially hydrolyzed octenyl succinate starch content is between 1 and 50% by weight of the total dry weight of said granules. 9 . The method according to claim 1 wherein said substance is a pharmaceutical active agent. 10 . A method for preparing pharmaceutical tablets exhibiting a disintegration time lower than 60 minutes comprising the steps of preparing granules according to claim 1 and a final step of compressing the granules in order to obtain tablets. 11 . A granule comprising one or several substances and a partially hydrolyzed waxy octenyl succinate starch having a weight average molecular weight from 10 4 to 10 6 g/mol, wherein said partially hydrolyzed waxy octenyl succinate starch is a waxy octenyl succinate that has been partially hydrolyzed with an alpha-amylase. 12 . A pharmaceutical tablet exhibiting a disintegration time lower than 60 minutes comprising a granule of claim 11 . 13 . A method of binding a substance powder in a wet granulation process, the method comprising: providing partially hydrolyzed waxy octenyl succinate starch having a weight average molecular weight comprised between 10 4 and 10 6 g/mol; and using the octenyl starch as a binder in the wet granulation process, wherein said partially hydrolyzed waxy octenyl succinate starch is a waxy octenyl succinate that has been partially hydrolyzed with an alpha-amylase. 14 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 4 to 10 5 g/mol. 15 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 5 to 10 6 g/mol. 16 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 500,000 g/mol. 17 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 400,000 g/mol. 18 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 300,000 g/mol. 19 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 200,000 g/mol. 20 . The method of claim 1 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight of 150,000 g/mol. 21 . The method of claim 1 , wherein said partially hydrolyzed octenyl succinate starch content is from 1 to 15% by weight of the total dry weight of said granules. 22 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 4 to 10 5 g/mol. 23 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 5 to 10 6 g/mol. 24 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 500,000 g/mol. 25 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 400,000 g/mol. 26 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 300,000 g/mol. 27 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight of from 100,000 to 200,000 g/mol. 28 . The granule of claim 11 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight of 150,000 g/mol. 29 . The method of claim 13 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 4 to 10 5 g/mol. 30 . The method of claim 13 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 10 5 to 10 6 g/mol. 31 . The method of claim 13 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 500,000 g/mol. 32 . The method of claim 13 , wherein the partially hydrolyzed waxy octenyl succinate starch has a weight average molecular weight from 100,000 to 400,000 g/mol. 33 .
