Embodiment 1

[0033] A kind of tilmicosin injection is made up of tilmicosin, astragaloside IV, ATP, cosolvent, antioxidant, stabilizer and injection water, wherein every 100ml solution contains tilmicosin 10g, astragaloside IV 1g , ATP 1g, lactic acid 5g, sodium bisulfite 0.1g, propylene glycol 15g, and water for injection to make up to 100ml.

[0034] Its preparation method is:

[0035] (1) Dissolve sodium bisulfite, ATP, and lactic acid in water for injection respectively, add tilmicosin, and stir to dissolve.

[0036] (2) Add astragaloside IV into propylene glycol and stir until dissolved. If necessary, it can be heated slowly, and the heating temperature is 55-60°C.

[0037] (3) Mix the two, adjust the pH value to 5.5 with lactic acid, dilute with water for injection, filter and sterilize.

Embodiment 2

[0039] A kind of tilmicosin injection is made up of tilmicosin, astragaloside IV, ATP, cosolvent, antioxidant, stabilizer and injection water, wherein every 100ml solution contains tilmicosin 20g, astragaloside IV 2g , ATP1.5g, citric acid 15g, Diaobaikuai 0.2g, polyethylene glycol-20015ml, water for injection to make up to 100ml.

[0040] Its preparation method is:

[0041] (1) Dissolve Diaobaikuai, ATP, and citric acid in water for injection, add tilmicosin, and stir to dissolve it.

[0042] (2) Add astragaloside IV into polyethylene glycol-200 and stir until dissolved. If necessary, it can be heated slowly, and the heating temperature is 55-60°C.

[0043] (3) Mix the two, adjust the pH value to 5.5 with citric acid, dilute with water for injection, filter and sterilize.

Embodiment 3

[0045] A kind of tilmicosin injection is made up of tilmicosin, astragaloside IV, ATP, cosolvent, antioxidant, stabilizer and injection water, wherein every 100ml solution contains tilmicosin 30g, astragaloside IV 3g , ATP 1.5g, Phosphoric Acid 12.5ml, Sodium Bisulfite 0.1g, Hangbaikuai 0.1g, Propylene Glycol 5ml, Polyethylene Glycol-200 15ml water for injection to make up to 100ml.

[0046] Its preparation method is:

[0047] Dissolve sodium bisulfite, diaobaikuai, ATP, and phosphoric acid in water for injection respectively, add tilmicosin, and stir to dissolve it.

[0048] Add astragaloside IV into the mixed solution of propylene glycol and polyethylene glycol-200 and stir until dissolved. If necessary, it can be heated slowly, and the heating temperature is 55-60°C.

[0049] Mix the two, adjust the pH value to 5.5 with phosphoric acid, dilute with water for injection, filter and sterilize.

Abstract

The invention provides tilmicosin injection as well as a preparation method and an application thereof. The tilmicosin injection is prepared from the following components in parts by weight: 10-50 parts of tilmicosin, 1-5 parts of astragaloside, 0.5-2 parts of ATP, 5-20 parts of a cosolvent, 0.1-0.5 part of an antioxidant, and 15-30 parts of a stabilizer. The tilmicosin injection is stable in property, remarkable in effect, and small in irritation and safe to the injected part, and can be mixed with inactivated vaccines for injection, so that the clinic application of the tilmicosin injection is expanded.

Description

technical field [0001] The invention relates to a tilmicosin injection and a preparation method and application thereof. Background technique [0002] Tilmicosin belongs to macrolide antibiotics for animals, and has good antibacterial activity against Gram-positive bacteria, Gram-negative bacteria, anaerobic cocci, Legionella, Mycoplasma, Chlamydia, etc. Linear bacilli, Pasteurella and mycoplasma have strong activity, and are widely used in the prevention and treatment of diseases such as bovine mastitis, swine mycoplasma pneumonia and livestock and poultry mycoplasma infection. It is sensitive to more than 95% of hemolytic Pasteurella, and its pharmacological effects are relatively Tylosin, erythromycin thiocyanate and other drugs were 3 to 5 times higher. [0003] However, tilmicosin injection must be used with caution. In the third chapter of the second edition of the "Handbook of Veterinary Medicine" edited by Zeng Zhenling, when introducing the macrolide tilmicosin, in...
