Abstract
A granulate is described containing granules of an active ingredient endowed with therapeutic/nutritional activity coated with a granulating/bonding agent, suitable for conversion into a solid administration form with a very high content of active ingredient, particularly in the form of tablets obtained by means of a direct compression procedure, or suitable for constituting the content of capsules.
Claims11
A granulated product containing granules of an active ingredient endowed with therapeutic/nutritional activity and a pharmacologically acceptable granulating/bonding agent, said granulated product being suitable for conversion into solid administration forms by means of a direct compression procedure, or for constituting the content of capsules, wherein said product consists of:
- (a) from 92 to 96% by weight, calculated in relation to the weight of the granulated product, of an active ingredient selected from the group consisting of L-carnitine inner salt, an alkanoyl L-carnitine inner salt, in which the straight- or branched-chain alkanoyl group has 2-6 carbon atoms, or one of their pharmacologically acceptable salts;
- and
- (b) from 4 to 8% by weight, calculated in relation to the weight of the granulated product, of a granulating/bonding material selected from the group consisting of polyvinylpyrrolidone, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxybutyl-cellulose, polyethyleneglycol, microcrystalline cellulose, cellulose acetate phthalate, methylcellulose, ethylcellulose, polyvinylalcohol, styrene maleic anhydride, and mixtures thereof.
A granulated product containing granules of an active ingredient endowed with therapeutic/nutritional activity and a pharmacologically acceptable granulating/bonding agent, said granulated product being suitable for conversion into solid administration forms by means of a direct compression procedure, or for constituting the content of capsules, wherein said product consists of:
- (a) from 92 to 96% by weight, calculated in relation to the weight of the granulated product, of an active ingredient selected from the group consisting of L-carnitine inner salt, an alkanoyl L-carnitine inner salt, in which the straight- or branched-chain alkanoyl group has 2-6 carbon atoms, or one of their pharmacologically acceptable salts;
- (b) from 4 to 8% by weight, calculated in relation to the weight of the granulated product, of a granulating/bonding material selected from the group consisting of polyvinylpyrrolidone, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxybutyl-cellulose, polyethyleneglycol, microcrystalline cellulose, cellulose acetate phthalate, methylcellulose, ethylcellulose, polyvinylalcohol, styrene maleic anhydride, and mixtures thereof;
- and
- (c) from 0.1 to 1% of amorphous silica by weight, calculated in relation to the weight of the granulated product.
