AI Technical Summary
Existing calcium carbonate preparations are prone to introducing moisture during wet granulation, which causes citric acid to absorb moisture, generating insoluble precipitates and carbon dioxide gas, affecting solubility and quality stability.
Polyethylene glycol 2000 was used for hot melt granulation to avoid the introduction of moisture, and oyster calcium carbonate was coated with a hydrophobic material to improve particle stability.
It effectively improves the solubility and quality stability of oyster calcium carbonate granules, avoids packaging bloating problems, and enhances calcium supplementation effect.
Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the field of pharmaceutical preparations, and particularly relates to oyster calcium carbonate granules and a preparation method thereof. BACKGROUND
[0002] Calcium is one of the important elements of human body composition, has very important physiological functions, and the calcium content in human body accounts for 1.5-2% of the total body weight. Calcium is not only the main material for constituting the skeleton, but also is necessary for maintaining the function of nerves and muscles, plays an important role in maintaining the normal functions of heart, kidney, lung and blood coagulation, and the permeability of cell membrane and capillary, and can regulate the secretion and storage of neurotransmitters and hormones, the uptake and utilization of amino acids, the absorption of vitamin B 12 Due to insufficient daily calcium intake of people, or special groups such as high calcium requirement of fast-growing young children, accelerated calcium loss of the elderly, and pregnant women due to fetal gestation, etc., sufficient calcium needs to be supplemented in addition to diet.
[0003] Oyster calcium carbonate is a natural active calcium source prepared from the shells of marine organisms oysters through high-temperature calcination and electrolytic activation process. Compared with traditional calcium carbonate, oyster calcium carbonate has higher solubility and bioavailability due to its unique microcrystalline structure, and is widely used in calcium supplementation for children, pregnant and lactating women, the elderly and other groups in clinical practice, and has been included in the standard preparations of Chinese, American, British and Japanese pharmacopoeias.
[0004] The existing calcium carbonate preparations generally use wet granulation, and citric acid needs to be added as a flavoring agent and an acidic regulator for promoting calcium absorption. The moisture introduced in the wet granulation process and the humidity of the storage environment can easily cause the citric acid to absorb moisture, trigger the acid-base reaction of the citric acid and the calcium carbonate, generate insoluble calcium citrate precipitate and carbon dioxide gas, and cause the preparation to be unqualified in terms of solubility (such as prolonged dispersion time, turbid solution) and packaging gas expansion. Therefore, how to improve the solubility of oyster calcium carbonate granules and ensure the stability of quality indicators is crucial to improve the calcium supplementing effect of oyster calcium carbonate.
