Abstract
The antiparasitic medicine prepared with macrolide antibiotics and in the form of powder, tablet, ointment, cream, or paste uses an 8-component oily mixture as main active component, as well as imidazole drug for high parasite-expelling effect to tapeworm, blood fluke, etc., and it is safe less consumption of B1, and easy to use.
Description
The present invention relates to prepare animal anthelmintic field with microorganism synthetic ten hexa-atomic macrolide antibiotics.
Avilamycin (Avermectins) is the metabolite of streptomycete Streptomyces Avermitilis, have wide spectrum, anti-insect activity efficiently, found this material in 76 years, the eighties U.S. Merok company successively succeeds in developing insecticide, anti-post the worm medicine and put on market.The mixture that avilamycin (Avermectins) is made up of eight quite similar homologues of structure, i.e. Avermeotin A

2The oily mixture of four pairs of components adds that as main effective ingredient adjuvant makes that the anthelmintic drug of different dosage form realizes, below is relevant detailed description of the present invention.
One, avilamycin oily mixture (hereinafter to be referred as AVM grease)
Avilamycin oily mixture (hereinafter to be referred as AVM grease) through PROCESS FOR TREATMENT such as decolourings and get, is main anthelmintic ingredient by lixiviating solution, this mixture consist of A
13～10%, A
28-15%, B
16-15%, B
23～10%, 14-18 carbon fatty acid: 35-40%, water: 10-15%.Its preparation technology is as follows:
Producing bacterial strain decolours → concentrates → AVM grease with acetone or ethyl acetate lixiviate → filtration (or centrifugal) → lixiviating solution through 10-11 days fermentation → filtration → mycelium.
Most side effect compositions can be removed through technologies such as decolourings.
Two, form formula and technology
The present invention includes the prescription and the production technology thereof that prepare powder, tablet, unguentum, ointment, five kinds of dosage forms of paste with AVM grease.
1. powder:

More than all can add B in five kinds of form formulas
1The imidazoles that 30-60 doubly measures, as albendazole, benzene sulfur imidazoles, several class parasites of not killing in order to avilamycin such as hold concurrently killing cestode and trematodiasis simultaneously.
Above-mentioned various dosage form shows that through the clinical practice on Xinjiang and other places to the most parasites in the control spectrum, its repelling and killing efficacy reaches more than 95%.
The present invention compared with prior art has following good effect
1. and B
1Crystallization product preparation is compared has identical curative effect, B still less
1Loss, lower cost, cost can reduce 50%-70%, and technology is simple, and is easy and simple to handle, aspect side effect such as toxicity and B
1The elaboration preparation is suitable.
2. compare with the mycelium preparation, it is close to have price, the characteristics higher to animal safety, and safety index is greater than more than 10 times of medicine regulation.
3. because of the equal tool insecticidal activity of its four pairs of components, on insecticidal spectrum, has complementary action, therefore at B
1Under the identical situation of concentration, because the effect of other component, anthelminthic effect is better.
Described below is several examples of five kinds of dosage form preparations:
