Problems solved by technology

Because the cell structure of mammals is quite different from that of microorganisms, and the liver and kidney functions of children are weaker than those of adults, the same concentration of preservatives is relatively safe for adults, but it will increase the burden on the liver and kidneys of children

Embodiment 1

[0107] Example 1 Sample 1 # ~Sample 6 # preparation of

[0108] The sample preparation steps are:

[0109] a) dissolving chlorpheniramine maleate and dextromethorphan hydrobromide in water to obtain aqueous solution I;

[0110] b) sequentially adding sodium citrate, citric acid, disodium edetate, sucralose, sodium metabisulfite and sorbitol to the aqueous solution obtained in step a), stirring and dissolving to obtain aqueous solution II;

[0111] c) adding phenylephrine hydrochloride to the aqueous solution II obtained in step b) and stirring to dissolve to obtain aqueous solution III;

[0112] d) Add grape essence to the aqueous solution III obtained in step c), stir evenly, and dilute with purified water to obtain the liquid preparation.

[0113] The relationship between the type and mass concentration of each component in the liquid preparation and the sample number is shown in Table 1.

[0114] Table 1

[0115]

Embodiment 2

[0116] Example 2 Sample 1 # ~Sample 6 # Determination of antibacterial ability

[0117] Get sample 1 obtained in embodiment 1 respectively # ~Sample 6 #Each of five samples was inoculated with Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, and Aspergillus niger, and cultured in an incubator. On the 28th day, samples were taken and the viable bacteria content in the samples was determined. The initial viable bacteria content and test results are shown in Table 2.

[0118] Table 2 Sample antibacterial ability test

[0119]

[0120] As can be seen from the data in Table 2, the liquid preparation provided by the technical solution of the present application still has a strong antibacterial effect and can achieve a complete antibacterial effect when the formula does not contain organic solvents and preservatives. .

Embodiment 3

[0121] Embodiment 3 accelerated test

[0122] According to the experimental procedure and formula in embodiment 1, repeat preparation sample 6 respectively # , to investigate the repeatability of the samples obtained during the preparation process. Take samples separately 6 # Samples from three different batches are recorded as sample 6 according to different batches # -n where n represents the batch number. For example sample 6 # -1 is the first batch of samples 6 # , sample 6 # -2 is the second batch of sample 6 # , sample 6 # -3 is the third batch of sample 6 # .

[0123] Respectively for the above sample 6 # -1~sample 6 # -3. A total of 3 batches of samples were used for accelerated experiments.

[0124] The test conditions are: stored at a temperature of 40±2°C and a relative humidity of 75±5%, at the 0th month, 1st month, 2nd month, 3rd month, and 6th month of storage respectively Sampling and analyzing the content of active ingredients, related substances a...

Abstract

The invention discloses a liquid preparation. The liquid preparation contains 0.13-0.15g / L of chlorpheniramine, 0.69-0.85g / L of dextromethorphan, 0.37-0.45g.L of phenylephrine, 0-100g / L of an organic solvent and 0-1g / L of an antiseptic. The liquid preparation has the advantages of good stability and strong bacteriostasis ability, and is suitable for being orally taken and being taken by children. The invention also discloses a preparation method of the liquid preparation. The preparation method has the advantages of simple process and high product quality stability.

Description

technical field [0001] The application relates to an oral liquid preparation, which belongs to the field of medicine. Background technique [0002] Cold is a common disease. It often occurs in the upper respiratory tract, and in severe cases, the lower respiratory tract will also be involved and cause complications. The onset is more acute, with symptoms such as dry throat and sneezing in the early stage, and then chills, runny nose, nasal congestion, low-grade fever, body aches, headache, and fatigue , anorexia (lack of appetite), bloating, constipation or diarrhea. Due to the many symptoms of colds, there is no single medicine that can alleviate all the above symptoms, so most of the current anti-cold medicines are compound preparations. [0003] A variety of compound cold liquid preparations composed of phenylephrine hydrochloride, dextromethorphan hydrobromide and chlorpheniramine maleate have been listed, but the formulations all contain organic solvents and preservat...
