Abstract

The invention belongs to the technical field of medicinal preparation processing, and particularly relates to a sodium bicarbonate enteric capsule and a preparation method thereof. The preparation method of the sodium bicarbonate enteric capsule comprises the following steps: adding a capsule shell material suitable for alkaline contents into water, heating and stirring to obtain a solution, and dipping with glue to obtain a hollow capsule shell; dipping the hollow capsule in an enteric coating solution, and drying to obtain an enteric hollow capsule shell; filling the content containing sodium bicarbonate, coating a sealing material solution at the sleeved part of the capsule, and drying to obtain the sodium bicarbonate enteric capsule. The capsule shell material suitable for the alkalinecontents is prepared from the following raw materials in parts by weight: 10-20 parts of hydroxypropyl methyl cellulose phthalate, 1-2 parts of curdlan and 0.5-1.5 parts of xanthan gum. According tothe invention, the enteric hollow capsule is filled with the alkaline contents, so adverse reactions of the stomach can be avoided, and the effects of neutralizing uric acid and protecting the intestinal tract can be more effectively realized; and compared with the coating by a spraying technology, the enteric hollow capsule has less influence on the contents.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparation processing, and in particular relates to a sodium bicarbonate enteric-coated capsule and a preparation method thereof. Background technique [0002] Gout, also known as "hyperuricemia", is a disorder of purine metabolism and belongs to arthritis. Gout is a disorder in the metabolism of purine substances in the human body. The synthesis of uric acid increases or the excretion decreases, resulting in hyperuricemia. When the blood uric acid concentration is too high, uric acid is deposited in the joints, cartilage and kidneys in the form of sodium salt, causing tissue foreign bodies. Inflammation, ie gout. Gout can cause kidney damage, including gouty nephropathy, acute obstructive nephropathy and urinary calculi. In addition, when the blood uric acid in the human body is excessively elevated and exceeds its saturation, white crystals are precipitated in certain parts of the body....
