Embodiment 1

[0021] The decoquinate solution, calculated by weight percentage, is mainly composed of decoquinate as the main material, and is prepared with an appropriate amount of polyethylene glycol and dimethylformamide.

[0022] Recipe and method:

[0023] Decoquinate 5%

[0024] Polyethylene Glycol 75%

[0025] Dimethylformamide 20%.

[0026] production method

[0027] (1) In the preparation in advance, the decoquinate weighed as required is dissolved with an appropriate amount of dimethylformamide for subsequent use;

[0028] (2) Add polyethylene glycol to the full amount, continue to stir to make it evenly mixed, stir the liquid medicine evenly under the condition of stirring, and then test it;

[0029] (3) After passing the inspection, it is filled and sealed under the condition of stirring, and then labeled, packaged, randomly inspected, and put into storage.

Embodiment 2

[0031] Study data and results of stability experiments, accelerated and long-term experiments.

[0032] accelerated test

[0033] Take this product, imitate the marketing package, put it in a desiccator filled with saturated sodium chloride solution (RH 75%±5%), and then place it in a constant temperature box with a temperature of 40°C±2°C. , Sampling in March and June to investigate the appearance, color, content, clarity, related substances, insoluble particles, sterility and bacterial endotoxin of the samples.

[0034] The results are shown in Table 1.

Abstract

The invention discloses a decoquinate solution which comprises the following raw materials by weight: 5% of decoquinate, 75% of alcoholic solvents, 20% of dimethyl formamide. The invention also discloses a preparation method of the decoquinate solution. With the mode that decoquinate is dissolved in organic solvents, the decoquinate is in a solution form, and is administrated in an oral liquid form. Decoquinate is highly liposoluble, is difficult to dissolve in water and common organic solvents, has a low premix dissolution rate, and low bioavailability; when decoquinate is developed into a solvent through a pharmaceutical method, the administration is convenient, and the bioavailability is high.

Description

technical field [0001] The invention relates to a decoquinate solution and a preparation method thereof. Background technique [0002] Decoxyquinate (English name: decoquinate; Deccox, chemical name: 6-decyloxy-7-ethoxy-4-hydroxy-3-quinolinecarboxylic acid ethyl ester), is an anticoccidial drug of quinolines , is effective against a variety of Eimeria coccidia, and is used to prevent chicken coccidiosis caused by various coccidiosis. Decoxyquinate plays a role in the asexual reproduction stage of coccidia. After entering the sporozoite cell, it prevents its development by interfering with DNA synthesis. It starts to play a role in the early life cycle of coccidia, so as to avoid damage to poultry intestinal tract, and can more effectively help farmers obtain higher economic benefits. Compared with maduramycin, the results show that the anti-coccidia If the index is greater than 180, decoquinate anticoccidial is a high-efficiency drug. No coccidia oocysts were detected in...
