Description
Technical field
The present invention relates to field of medicaments, more particularly to a kind of oral solution of chitosan and preparation method thereof.
Background technology
Chitosan (chitosan, CTSH) is a kind of natural macromolecule alkaline polysaccharide next in number only to cellulose, by
Glucose (β copolymers (1-4) and 2-amino-2-deoxy-D-Glucose) and N-acetyl-glucosamine (2-acetamido-2-
Deoxy-d-glucose it) forms.
Chitosan has a variety of pharmacological activity, and such as bacteriostasis, antitumor action reduce blood glucose, reduce lipid-loweringing sterol, anti-
Hypertension, strengthen liver function, Acidinhibitor, the healthcare function for gastrointestinal system, anticoagulant active, anti thrombotic action,
Immunologic enhancement.But chitosan is insoluble in water, and bioavilability is poor in body, it is difficult to give full play to its bioactivity work(
Energy.
Chinese patent CN101298502 discloses a kind of chitosan solid dispersion, specifically by chitosan and poly- second two
Alcohol 4000- Macrogol 6000s are mixed with to obtain, to increase the water solubility of chitosan.Still there are chitosan microball, nanoparticle system
The report of agent, as Chinese patent CN101978954A discloses a kind of preparation method and its usage of chitosan microball.
Dispersion degree of the oral liquid with drug is big, it is fast to absorb, and drug effect can be played rapidly by comparing with solid dosage forms;Easily
It is convenient to take in divided dose, therefore be clinically widely used.Currently, not finding the oral solution of chitosan in the market.
Invention content
The purpose of the present invention is being directed to problems of the prior art, a kind of chitosan oral solution, the oral solution are provided
Middle chitosan dissolubility is high, and better stability of preparation can ensure clinical application safety and validity, and convenient to take.
In view of chitosan poorly water-soluble, inventor is added to solubilizer, to carry during studying chitosan oral solution
Rise its solute effect.The increase of solubilizer can make solubilizing effect have certain increase, but excessive solubilizer can make biological utilisation
The raising of degree reaches saturation.Type and dosage of the present invention also to solubilizer in chitosan oral solution have carried out preferably.The present invention
Chitosan oral solution solubilizer and chitosan are interacted so that chitosan is completely dissolved in the solution.
Since the dispersion degree of drug in liquid preparation is big, there is larger boundary and interface energy, accordingly, there exist certain journeys
The unstability of degree, and aqueous liquid preparation is easy to go mouldy.For different drugs, it should be selected according to its own feature
Suitable auxiliary material and its amount ranges ensure safety and the validity of clinical application to obtain preferable stability.
The present inventor finally determines technical scheme of the present invention by a large amount of experimental study.
The present invention is achieved by the following technical solutions.
The present invention provides a kind of chitosan oral solution, which includes the supplementary material of following weight proportion:
6~12 parts by weight of chitosan;
0.5~3.5 parts by weight of solubilizer;
0.1~0.5 parts by weight of preservative.
Preferably, the chitosan oral solution includes the supplementary material of following weight proportion:
8~10 parts by weight of chitosan;
1.2~2.0 parts by weight of solubilizer;
0.2~0.3 parts by weight of preservative.
In the chitosan oral solution of the present invention, the one kind of the solubilizer in propylene glycol, polyethylene glycol, tween
Or it is a variety of;Preservative is one or more in ethylparaben, propylben, Potassium Benzoate.
The polyethylene glycol is cetomacrogol 1000, Macrogol 4000, Macrogol 6000 or PEG 8000
In one kind.
The tween is one kind in polysorbas20, polysorbate40 or polysorbate60.
As more preferred embodiment, the solubilizer is that weight ratio is 1:0.2 propylene glycol and polysorbate40;On
The dissolubility of chitosan can be significantly improved by stating the solubilizer, and chitosan oral solution obtained is clarified, no muddiness.
Further, it is 1 that the preservative, which is weight ratio,:1 ethylparaben and propylben.
The present invention also provides the preparation methods of the chitosan oral solution.
The preparation method of oral solution comprises the steps of:Solubilizer is added in 1/3~2/3 purified water, is stirred evenly, so
After be added chitosan, 35~40 DEG C of stirrings are to being completely dissolved;Preservative is added, after mixing plus purified water is to 1000ml, fills
Dress, 115 DEG C sterilizing 15~20 minutes to get.
The present invention chitosan oral solution accelerated test investigate the result shows that, character, microbial limit, pH value and drug
Content has no significant change compared with 0 month, and stability is good.The present invention chitosan oral solution long term test investigate the result shows that,
Its character, microbial limit, pH value and medicament contg have no significant change compared with 0 month, and stability is good.With comparative example 1, comparison
Example 2 is compared, and chitosan stability of Oral of the invention is more preferable, shows that the chitosan oral solution component of the present invention and proportioning are closed
Reason.
The chitosan oral solution of the present invention compared with prior art, has the following advantages that:
1, by the present invention in that with specific auxiliary material and its dosage so that the stability of oral solution is good, ensure that clinical use
The safety of medicine and validity.
2, chitosan oral medicine liquid dispersion degree of the present invention is big, it is fast to absorb, and convenient to take, drug effect plays rapid.
3, chitosan oral solution of the invention is simple for process, at low cost, is suitble to industrialized production.
