Abstract

The invention relates to a composite gel suppository, which is characterized in that sodium carboxymethyl cellulose is compounded with other gels to form a suppository base. The suppository has a hollow thin shell shape. The composite gel suppository has the following advantages that: 1, the suppository has the function of hemostasis; 2, the suppository has the function of inhibiting fungus growth; 3, a preparation of the suppository is more stable; 4, the pharmaceutical ingredients of the suppository can be released slowly and lastingly to improve the curative effect; 5, the suppository is convenient to use because the gel suppository can absorb water (tissue fluid) quickly to expand and is dissolved in anus, vagina or uterus, nasal cavity and auditory meatus to generate bio-adhesion so that the gel suppository is adhered to cavities and meatuses and the medicinal liquid of the suppository is not easy to flow out without generating overflow, thus an obstructing object is unnecessary to be used in the vagina or the anus; 6, the gel suppository does not have pungency; and 7, the suppository is biodegradable in a body without residues and toxic side effects, and is easier to be accepted by a patient under the condition of enhancing curative effect.

Description

technical field [0001] The invention relates to a composite gel suppository capable of carrying multiple medicines, which is composed of sodium carboxymethyl cellulose and other gels to form a suppository base. The suppository is in the shape of a hollow thin shell. Background technique [0002] Suppository bases are generally divided into fatty bases and water-soluble bases. Water-soluble matrices are generally considered slightly more irritating than aliphatic matrices, which are widely used. However, suppositories with aliphatic bases soften or melt at body temperature. Therefore, during preparation, their melting points need to be adjusted below human body temperature. Such a suppository has a storage condition problem, and the suppository needs to be stored at a temperature of 20° C. to 30° C. Since the lipid has a tendency to flow downward after melting, the drug solution overflows, which also affects part of the curative effect. The solution is to plug the barrie...
