Abstract
Ascorbic acid compositions in the form of a powder and/or granules contain as principle components L-ascorbic acid and/or a pharmaceutically acceptable salt thereof, and a high molecular (300 kDalton or higher) pectin. The compositions are compressible into tablets with improved mechanical strength and hardness.
Claims
exact text as granted — not AI-modified1 . A composition in the form of a powder or granules comprising:
(a) L-ascorbic acid and/or a pharmaceutically acceptable salt thereof, (b) high molecular pectin.
2 . A composition according to claim 1 , wherein the high molecular pectin has an average molecular weight of about 300 kDalton or higher.
3 . A composition according to claim 1 , wherein the high molecular pectin has an average molecular weight of about 300 kDalton to about 400 kDalton.
4 . A composition according to claim 1 , wherein the high molecular pectin has an average molecular weight of about 350 kDalton.
5 . A composition according to claim 1 wherein the L-ascorbic acid and/or a pharmaceutically acceptable salt thereof is sodium L-ascorbate.
6 . A composition according to claim 1 , wherein the pectin is present in quantities within the range of about 0.1% to about 10% by weight, calculated on the total weight of the composition.
7 . A composition according to claim 1 , wherein the pectin is present in quantities within about 0.5% to about 2% by weight, calculated on the total weight of the composition.
8 . A composition according to claim 1 , wherein said composition consists of 95-99% by weight of L-ascorbic acid and/or a pharmaceutically acceptable salt thereof and 5-1% by weight of pectin, the two components totaling 100% by weight.
9 . A composition according to claim 1 in the form of a compressed tablet.
10 . (Canceled).
11 . A composition according to claim 1 further comprising an adjuvant or excipient.
12 . A composition according to claim 2 wherein the L-ascorbic acid and/or a pharmaceutically acceptable salt thereof is sodium L-ascorbate.
13 . A composition according to claim 3 wherein the L-ascorbic acid and/or a pharmaceutically acceptable salt thereof is sodium L-ascorbate.
14 . A composition according to claim 4 wherein the L-ascorbic acid and/or a pharmaceutically acceptable salt thereof is sodium L-ascorbate.
15 . A composition according to claim 11 wherein the L-ascorbic acid and/or a pharmaceutically acceptable salt thereof is sodium L-ascorbate.
16 . A composition according to claim 5 , wherein the pectin is present in quantities within the range of about 0.1% to about 10% by weight, calculated on the total weight of the composition.
17 . A composition according to claim 11 , wherein the pectin is present in quantities within the range of about 0.1% to about 10% by weight, calculated on the total weight of the composition.
18 . A composition according to claim 5 , wherein the pectin is present in quantities within about 0.5% to about 2% by weight, calculated on the total weight of the composition.
19 . A composition according to claim 5 , wherein said composition consists of 95-99% by weight of L-ascorbic acid and/or a pharmaceutically acceptable salt thereof and 5-1% by weight of pectin, the two components totaling 100% by weight.
20 . A composition according to claim 5 in the form of a compressed tablet.Join the waitlist — get patent alerts
