Formulations and methods of manufacturing formulations for use in colonic evacuation
View Patent ↗Formulations and methods of manufacturing formulations for use in colonic evacuation are disclosed herein, in an embodiment, a solid dosage formulation includes an intra-granular fraction intermingled with an extra-granular fraction, wherein the intra-granular fraction includes granules comprising at least one osmotic evacuant agent, at least one antacid, and a first pharmaceutically acceptable excipient component, and wherein the extra-granular fraction includes one or more organic acids, a non-metallic lubricating element, and a second pharmaceutically acceptable excipient component.
1. A coated tablet, comprising: an intra-granular fraction combined with an extra-granular fraction, and a coating layer,
wherein the intra-granular fraction includes granules comprising micronized sodium picosulfate, microcrystalline cellulose, magnesium oxide, and crospovidone, and wherein the intra-granular fractions excludes sodium starch glycolate,
wherein the extra-granular fraction includes one or more organic acids, microcrystalline cellulose, and crospovidone, and wherein the extra-granular fraction excludes sodium starch glycolate and magnesium stearate,
wherein the organic acid is one of ascorbic acid, citric acid, tartaric acid, or combinations thereof, and
wherein the coating layer delays dissolution beyond the mouth of a patient.
2. The coated tablet of claim 1 wherein the intra-granular fraction comprises about 50% of the total weight of the formulation, and wherein the extra-granular fraction comprises about 50% of the total weight of the formulation.
3. The coated tablet of claim 1 wherein the at least one organic acid is ascorbic acid.
4. The coated tablet of claim 1 , wherein the coated tablet shows no signs of degradation at 16 weeks.
5. The coated tablet of claim 1 , further comprising silicon dioxide.
