Technical Field
The invention belongs to the technical field of veterinary medicines, and particularly relates to a suspension injection containing iron dextran and potazuril and a preparation method thereof, which are suitable for simultaneously preventing and treating coccidiosis and iron deficiency anemia of animals.
Background
Coccidiosis and iron deficiency anemia, which are frequently caused by animal diseases in the modern livestock breeding industry, are frequently generated in young animals, have high morbidity and rapid disease aggravation, seriously affect the growth and development of the animals and even cause death.
The iron storage at birth (40-50 mg) and the iron obtained from breast milk during lactation (about 1mg/d) are very limited, which results in piglets being prone to iron deficiency during the first week after birth. Clinically, the method mainly adopts intramuscular injection iron supplement or indirect iron supplement for sows, and farmers mostly adopt an intramuscular injection mode to supplement iron for piglets because the iron supplement amount for the supplementary feeding of sows is limited.
As coccidiosis is also frequently occurred in the young stage, piglets are usually caught again within 2-3 days after iron supplement is completed in clinic, and the anti-coccidiosis drugs are orally taken.
The mode of treating only one disease brings huge workload to farmers, increases the drug cost, brings huge pressure to animals, influences the normal growth and development of the animals, and finally influences the economic benefit of cultivation.

Viscosity-mPas | 76.3 | 36.3 | 90.4 | 84.1 | 65.7 | 80.1 |
Volume ratio of sedimentation | 0.99 | 0.50 | 0.99 | 0.98 | 0.96 | 0.98 |
From the experimental results, the preparation of example 2 without n-butanol has low viscosity, obvious drug sedimentation during standing, no compliance with the standard requirements of veterinary drugs, and poor stability; the formulations of examples 1, 3, 4, 5 and 6 all had drug precipitation ratios greater than 0.9 during standing, indicating good dispersibility, suggesting that the use of n-butanol can significantly improve the precipitation of patotelepril and improve formulation stability.
Experimental example 2 stability test
Referring to the requirements of 'technical specification for veterinary drug stability test', the following tests are designed:
the suspension injection products of examples 1, 4, 5 were subjected to stability acceleration tests. The test conditions are as follows: the formulation samples of the above examples were placed in an incubator at 40 + -2 deg.C/RH 75 + -5%, sampled at 1 st, 3 rd and 6 th months, observed for their properties, and measured for their contents by HPLC, and the test results are shown in Table 2 below.
The method for measuring the content of the patozeli comprises the following steps:
octadecylsilane chemically bonded silica is used as a filling agent; acetonitrile-phosphate buffer (v/v 45:55) is used as mobile phase, the detection wavelength is 254nm, and the number of theoretical plates is not less than 3000 according to the calculation of Paltoreq Lifeng.
The determination method comprises the following steps: taking a proper amount of sample, precisely weighing, adding acetonitrile for quantitative dilution to prepare a solution containing about 0.2mg in each 1ml, precisely weighing 10 mu l, injecting into a liquid chromatograph, recording a spectrogram until the retention time of a main peak is 2 times, and taking a Potiron reference substance for determination by the same method. And taking another sample, simultaneously measuring the relative density of the sample, converting the mass of the sample into milliliters, and calculating by peak area according to an external standard method to obtain the product.
TABLE 2 accelerated stability test results
From the above experimental results, the products of examples 1, 4 and 5 have no change in properties and sedimentation ratio of more than 0.9 in the accelerated stability test period, which indicates that the dispersibility is good and the content has no obvious change, and all indexes are in accordance with the requirements, indicating that the product has good stability.
Experimental example 3 detection of free iron
Refer to the examination method of free iron under the item of "iron dextran" in the 2015 edition of Chinese pharmacopoeia. 0.7ml of the injection suspensions prepared in examples 1 and 6, 1ml of the injection suspension prepared in example 2, 0.4ml of the injection suspension prepared in example 3, and 0.9ml of the injection suspension prepared in example 5 (both approximately equivalent to about 0.1g of iron dextran) were taken, placed in a 50ml Nardostachys colorimetric tube, 10ml of water was added and shaken to dissolve, 1.0ml of standard iron stock solution and 15g of potassium thiocyanate solution were added and placed in a 100ml measuring flask, and after dissolving about 50ml of water, 15ml of acetone was added, diluted to the scale with water and shaken to mix with 24ml of acetone, shaken to stand, and the color of the supernatant was observed. If color development occurs, it should not be darker (0.2%) than the control solution prepared by the same method, which is 3.0ml of the standard iron stock solution.
The colors were observed according to the above method as follows:
TABLE 3 color observations
From the above experimental results, the products of examples 1, 3, 5, and 6 showed no color change compared to the product of example 2 with a very small amount of disodium ethylenediaminetetraacetate added, showing a reddish-brown color; example 4 the level of free iron is higher due to the simultaneous increase in active iron content, but is still controlled by disodium edetate. The results show that the disodium ethylene diamine tetraacetate is used in the preparation of the invention, so that the content of free iron can be obviously reduced, and the risk of adverse reaction in the injection process can be reduced.
Experimental example 4 evaluation of bubble Performance
Appropriate amounts of the suspension injection samples prepared in examples 1 to 6 were selected, respectively, and loaded into test tubes with scales, and the test tubes were vigorously shaken for 30 seconds, respectively, and the heights of the formed foams were measured at time points of 1min, 3min, 5min, and 10min immediately after shaking, with the following results:
TABLE 4 evaluation of bubble Properties
The above experiments show that the products of examples 2, 5 and 6, which are not added or added with a very small amount of simethicone, have long dissipation time of bubbles generated in the shaking process, and are not beneficial to clinical use; the samples of examples 1, 3 and 4 can inhibit the generation of foam during the shaking process of the injection by adding simethicone, accelerate the disappearance of the foam, facilitate the clinical use and reduce the risk of injecting air.
Experimental example 5 evaluation of anticoccidial Effect
Coccidian-infected piglets of 3 days old (body weight about 3-4 kg) were selected as subjects, and 3 groups were provided, each group having 10 subjects. One group of animals orally took drinking water as a blank group, one group of animals orally took toltrazuril (Baycox 5% oral suspension, Bayer, administered once as a prescription, 20mg per kg body weight) as a control group, and the other group injected 1.5ml of the suspension injection of example 4 intramuscularly once for treatment, and the excretion of oocysts of piglets in each group was observed, and the excretion of oocysts among different groups was quantitatively evaluated by using Mann-whitney U test; piglets of the combined control group of the example were bled at different time points after administration, and the serum concentration of the drug was measured (the detection method can be found in Shen morning, Hohao Yuan, Hokking, et al. the methodology for measuring patozuril in pig plasma by HPLC method [ J ]. Chinese veterinary medicine journal, 2019). The day of administration was taken as day one and the day before as day 0. The results are shown in tables 5 and 6.
