Iron-dextrin long-acting injection and preparation method thereof

Abstract

The invention relates to iron-dextrin long-acting injection and a preparation method thereof. The iron-dextrin long-acting injection is used for piglet iron supplement iron, and has the advantages that the release, absorption, distribution, metabolism and excretion processes of an iron preparation can be prolonged in vivo, so that the purpose of prolonging the action of a drug can be achieved, the number of the dosing times can be reduced, the complicance of livestocks is improved, the blood concentration can be stable, the peak and valley phenomena can be avoided, the side effects of the drug can be facilitated to be reduced, the total drug dosage is reduced, and further, the maximum drug effect by the minimum dosage is achieved. Thus, the iron-dextrin long-acting injection can completely play the role of long-acting iron supplement in the prevention and the cure of piglet iron-deficiency anemia.

Description

technical field [0001] The invention belongs to the field of veterinary drugs, in particular to a long-acting iron supplement injection used for preventing and treating piglet iron deficiency anemia and a preparation method thereof. Background technique [0002] Iron is an essential trace element for the growth and development of suckling piglets, and is a component of various enzymes in the body. Newborn piglets have the least amount of iron in their bodies, requiring 15 mg of iron per day, and up to 1 mg of iron can be obtained in breast milk per day. Therefore, the iron stored in the piglet will soon be depleted, and if it is not replenished in time, anemia may occur. Iron deficiency anemia in piglets can occur throughout the year, but it occurs more in winter and spring than in other seasons. In general closed feeding, the disease is more common in suckling piglets within 1 month of age (especially within 2 weeks to 3 weeks). Piglets suffering from anemia have decreas...

Problems solved by technology

Although this method can effectively prevent iron deficiency symptoms in piglets, such iron injections on the market generally have high injection stress, and the drug is not released smoothly in the body. After the basic metabolism is completed, iron deficiency symptoms will appear again. Therefore, re-injection is often required to ensure the iron requirement in the body. This will not only cause waste, but also cause injection stress to piglets after multiple injections, which is not conducive to the growth of piglets. waste of manpower and material resources
