Valnemulin hydrochloride self-emulsified oral nano emulsion for veterinary use and preparation method thereof

The invention discloses valnemulin hydrochloride self-emulsified oral nano emulsion for veterinary use and a preparation method thereof. The valnemulin hydrochloride self-emulsified oral nano emulsion for veterinary use comprises the following components: valnemulin hydrochloride, oil, surfactant, preservative, antioxygen and auxiliary surfactant. After disintegrating in water and being stirred slightly or being taken orally and moving with intestine movement, the self-emulsified emulsion can spontaneously form emulsion with emulsion droplet size of 10 to 100 nanometers; the drawbacks of decomposition of valnemulin during long standing and content reduction of the valnemulin or valnemulin hydrochloride nano emulsion prepared in the prior art are overcome and the content stability of the product is increased; the palatability of the valnemulin product is improved; and the preparation process is simple, and the valnemulin hydrochloride self-emulsified oral nano emulsion is suitable to be produced in large scale by veterinary medicine enterprises.
