AI Technical Summary

Benefits of technology

This patented technology describes how certain compounds like sabetoxacillustrel or other types of herb extract have potential benefits such as improved absorption efficiency, increased safety due to their low molecular weight compared to common synthetically produced medicine ingredient(SDM)-Oral Liquid Mixture (OLMS)). These properties make them more effective than existing methods used alone. They improve patient acceptance and tolerances, lower costs associated with manufacturing these products, provide greater flexibility towards developing new therapies targeting specific diseases without causing damage to animals themselves, and offer longer periods before they die out naturally. Additionally, the use of nanopartides allows for precise control over administration amounts and reduces environmental impact caused by disposable plastic containers. Overall, this innovant product provides technical solutions for delivering safer and more efficacious treatments against various illnesses related to buckling turtles.

Problems solved by technology

This patent describes different ways to make certain compounds called macrocidones like avermitcs act similarly without causing harmful side reactions when taken into humans. However, these techniques can lead to reduced effectiveness due to their low solubilities in aqueous solutions compared to others.

preparation example Construction

[0032] The preparation method of selamectin injection of the present invention is as follows:

[0033] (1) ethyl oleate, OP, n-butanol, water for injection and selamectin of formula quantity are taken for subsequent use;

[0034] (2) At room temperature, stir and mix the ethyl oleate, OP, n-butanol, and selamectin weighed in step (1) at a constant temperature until the drug is completely dissolved in the system, and no traces are visible to the naked eye. up to solids;

[0035] (3) Slowly add water for injection to the mixture, and stir while adding; at the beginning, the viscosity of the system is small, and as the amount of water increases, the system gradually becomes viscous, and when the liquid crystal phase changes in the system, it is W / O type injection Continue to add water for injection dropwise and stir constantly. When the amount of water reaches a certain amount, the system becomes clear and thin, and the fluidity becomes better, that is, O / W type injection; then ...

Embodiment 1

[0041] The formula of selamectin injection of the present invention is as follows:

[0042] Ethyl oleate 8mL, OP 12mL, n-butanol 10mL, selamectin 10g, ultrapure water 70mL.

[0043] The preparation method of selamectin injection of the present invention is as follows:

[0044] 1) Weigh 8 mL of ethyl oleate, 12 mL of OP, 10 mL of n-butanol, 10 g of selamectin, and 70 mL of ultrapure water;

[0045] 2) At room temperature, place the above-mentioned weight of ethyl oleate, OP, n-butanol, and selamectin on a constant temperature magnetic stirrer at 200-400rpm and stir until the selamectin is completely dissolved in the system , until no solid matter is visible to the naked eye;

[0046] 3) Slowly add ultrapure water to the mixture, and stir while adding; at the beginning, the viscosity of the system is small, and as the amount of water increases to 16mL, the system gradually becomes viscous, and at this time the system may appear liquid crystal phase or W / O (Water-in-oil type) ...

Embodiment 2

[0049] Continue to add water for injection dropwise to the system of Example 1 under the stirring condition of 200~400rpm. When the amount of water for injection reaches 170mL, a clear and transparent O / W type Selamectin content of 5% (W / V) is prepared. Laramectin injection, at this time, the content of other medical excipients is reduced to 15%, which are all within the dosage range of medical excipients; it is suitable for clinical use of animals with larger body weight such as cattle, horses, camels, and elephants, and the higher drug content can be reduced Dosage for injection.

[0050] 5% (W / V) selamectin injection is detected by transmission electron microscope, and the appearance of the injection prepared according to the formula is clear and translucent, light yellow liquid; the particle size distribution of emulsion droplets is between 10-100nm, and the average particle size 65nm.

Abstract

The invention provides selamectin injection. The selamectin injection is prepared from the following components with percentage composition: 0.08-8% (V/V) of ethylis oleas, 0.12%-12% (V/V) of OP, 0.1%-10% (V/V) of n-butyl alcohol, 70%-99.7% (V/V) of water for injection, and 0.1%-10% of selamectin. The invention further provides a preparation method of the selamectin injection. The selamectin injection is high in drug-loading capacity and stable in placement, compared with the transdermal preparation, the selamectin injection has the advantages that the clinical use amount of selamectin is reduced, namely, the clinical use amount is reduced to 0.2mg/kg from 6mg/kg, but the curative effects are the same, and no obvious toxic and side effects exist; the selamectin injection is clear and transparent in appearance, for the 1% of preparation liquid commonly used clinically, the particle size distribution is 10-100 nm, 50nm in average, and the dispersity is good; the selamectin injection can be diluted to nanometer injections with different concentration gradients by adopting water for injection according to the actual clinical demand.
