Problems solved by technology

Water injections and capsules are administered systemically and cannot be applied locally; gels are used locally, but the existing gels have poor adhesion and the matrix is ​​a water-soluble substance. If used for local application in the oral cavity, the retention time is very long. short, does not have the desired effect

Abstract

A deproteinized oral cream of calf serum is prepared proportionally from the deproteinized extract powder of calf serum, anesthone, carboxymethyl cellulose sodium, pectin, hydroxyphenyl ethylester, menthol, atoleine and white vaseline. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a biochemical drug oral ointment preparation and a preparation method thereof. Background technique [0002] At present, the pharmaceutical dosage forms of deproteinized calf serum extract include water injection, gel and capsule, among which water injection is the most widely used. Water injections and capsules are administered systemically and cannot be applied locally; gels are used locally, but the existing gels have poor adhesion and the matrix is ​​a water-soluble substance. If used for local application in the oral cavity, the retention time is very long. Short and not as effective as it should be. Contents of the invention [0003] The object of the present invention is to provide a kind of oral ointment which uses calf serum deproteinized extract as active ingredient. [0004] Calf serum deproteinized oral ointment provided by the present invention, its formula comprises the following components in parts by weight:...
