Abstract
Description
field of invention
[0001] The invention relates to a preparation method of a montmorillonite suspension, which belongs to the technical field of medicines. Background technique
[0002] Montmorillonite is a drug that has been proved to be effective in treating diarrhea with few toxic and side effects. The montmorillonite preparations developed since the 1990s include powders, granules, dispersible tablets, gels, and suspensions. The above-mentioned dosage forms are due to the rapid drug effect of the suspension; easy to divide doses; suitable for infants and elderly patients; convenient to take; and are very popular with patients.
[0003] Existing montmorillonite suspension preparation method is, in order to improve the stability of suspension, increase the viscosity of dispersion medium to reduce the settling velocity of montmorillonite particle, add glycerin, gum arabic, peach gum, sodium alginate, Agar cellulose and other suspending agents. Due to the high viscosity, ...
Examples
Embodiment 1
[0021] Montmorillonite suspension formula:
[0022] Montmorillonite 300g Glucose 74.9g Sodium Saccharin 0.7g
[0023] Vanillin 0.4g Sodium Benzoate 9 Deionized Water 15000g
[0024] Preparation:
[0025] (1) Weigh the raw materials and auxiliary materials of the formula formula.
[0026] (2) Add montmorillonite into deionized water and stir evenly, then add sucrose and sodium benzoate, and stir evenly.
[0027] (3) Process the uniformly stirred mixed solution with a colloid mill to form a uniform suspension with a fineness of montmorillonite particles less than 10 μm.
[0028] (4) Suspension through cobalt 60 After irradiation sterilization, it can be obtained by dispensing.
Embodiment 2
[0030] Montmorillonite suspension formula:
[0031] Montmorillonite 200g, sucrose 150g, ethylparaben 0.5g,
[0032] Propylparaben 0.5g, deionized water 13000g.
[0033] Preparation:
[0034] (1) Weigh the raw materials and auxiliary materials of the formula formula.
[0035] (2) First add montmorillonite into deionized water and stir evenly, then add sucrose, glucose, ethylparaben and propylparaben and stir evenly.
[0036] (3) The homogeneously stirred mixed solution is then ultrasonically treated to form a uniform suspension with a particle size of montmorillonite less than 10 μm.
[0037] (4) After the suspension is boiled for 15 minutes to sterilize, it can be packaged separately.
Embodiment 3
[0039] Montmorillonite suspension formula:
[0040] Montmorillonite 250g, Aspartame 0.7g, Vanillin 0.3g,
[0041] Ethylparaben 5g, sodium benzoate 45g, deionized water 17000g.
[0042] Preparation:
[0043] (1) Weigh the raw materials and auxiliary materials of the formula formula.
[0044] (2) First add montmorillonite into deionized water and stir evenly, then add sucrose, glucose, ethylparaben and sodium benzoate and stir evenly.
[0045] (3) Process the uniformly stirred mixed solution with a homogenizer to form a uniform suspension with a fineness of montmorillonite particles less than 10 μm.
[0046] (4) The suspension was heated at 70°C for 1 hour, then placed at room temperature for 24 hours, and then heated at 70°C for 1 hour, and the heating and placing operations were continuously sterilized for 3-5 times.
