Abstract

An improved weight and growth stimulant for domesticated animals such as cattle, pigs and sheep is comprised of an anabolic agent that is subcutaneously administered in the form of a dual release implant formulation. Increased gains are particularly improved when zeranol is administered in an immediate-release and controlled-release formulation which allows for a one-time dosage injection.

More particularly, the present invention discloses a dual formulation; a sputum that stimulates growth and weight gain σ of livestock. BACKGROUND OF THE INVENTION Recent advances in veterinary science and veterinary § pharmacology have resulted in the growth and development of larger, healthier and heavier cattle, pigs, sheep and horses. In particular, with regard to cattle, sheep and herds, the need to feed the world's population through the production of meat provides the impetus to raise livestock as quickly and as large as possible.

合成代謝劑廣泛地用以促進牛與其他家畜之生長,而且 經刺激之生長促進對養牛業者為希望的,因為其使體重增 加速率及平均所消耗食物量之體重增加之絕對量(稱為餵 食效率)最大。通常,類固醇以生物可降解或非生物可降 解之可移植,隨時間釋放藥丸之形式供應給動物,其使用 移植裝置注射至皮膚下。其已證明為成功的;然而,動物 在其生長期間可能必須移植2-4次。Anabolic agents are widely used to promote the growth of cattle and other livestock, and stimulated growth promotion is desirable for cattle farmers because it increases the rate of weight gain and the average amount of weight gain of the average amount of food consumed (called Feeding efficiency is the biggest. Typically, the steroid is supplied to the animal as a biodegradable or non-biodegradable, transplantable tablet over time, which is injected into the skin using a graft device. It has proven to be successful; however, animals may have to be transplanted 2-4 times during their growth.

用於這些類固醇藥丸之皮下輸送之移植裝置包括一個具 有把手之手搶形外殼,一個位於外殼前侧之用以將藥丸注 射動物體内之中空針頭,及一個推棒。推棒可滑入針頭中 且支撐於外殼中而可縱向地排放。外殼中提供一個室且連 接針頭。插入含藥丸之藥盒且可在其中排放。可縱向地排 放之回壓裝置(針筒退出器)平行外殼中之推棒及中空針頭 而安置於外殼中。推棒與回壓裝置籍驅動機構移動,其類 似地提供於外殼中且其藉由操作緊固於把手之槓桿(板機)The grafting device for subcutaneous delivery of these steroid pellets includes a handle-shaped outer casing having a handle, a hollow needle on the front side of the outer casing for injecting the pill into the animal, and a pusher. The push rod can be slid into the needle and supported in the housing for longitudinal discharge. A chamber is provided in the housing and the needle is connected. The pill-containing kit is inserted and can be discharged therein. The longitudinally retractable back pressure device (needle retractor) is placed in the outer casing in parallel with the push rod and the hollow needle in the outer casing. The push rod and the back pressure device are moved by a drive mechanism, which is similarly provided in the housing and which is operated by a lever fastened to the handle (board machine)

Inventions and actions. Thus, the arcuate gear segment of the coupling lever and the gear returning device and the gear of the push rod are coupled to the driving mechanism and the back pressure device. This device is described, for example, in U.S. Patent 5,5 1 4,1 0 1 . Protein anabolic hormone (Formula I, C A S registration number: 2 6 5 3 8 - 4 4 - 3 ) is a synthetic generation that shows significant results in the promotion of bovine weight gain and growth.

式I 謝劑。蛋白同化激素,一種間苯二酚酸内酯衍生物,已顯 示對動態蛋白質新陳代謝有正面之影響。然而,在牛之生 長與發育時,為了最適之結果,現今含蛋白同化激素或其 他此種合成代謝劑之配方必須在1 7 0天生長與發育期間施 藥至少兩次。明顯地,此必要性將牛由草原帶回,再注射 移植物而且再送出,其為費力且費時之程序。 已測定蛋白同化激素與其他合成代謝在早期及在動物全 部生長循環施藥時提供最佳之生長及重量增加結果。其需 要迄今仍為不可能之立即釋放/持續釋放雙重配方。Formula I herbicide. Protein anabolic hormone, a resorcinol lactone derivative, has been shown to have a positive effect on dynamic protein metabolism. However, in the growth and development of cattle, for the most appropriate results, the formulation of protein-containing anabolic hormones or other such anabolic agents must be administered at least twice during the growth and development period of 170 days. Obviously, this necessity brings the cattle back from the grasslands, injects the grafts and delivers them again, which is a laborious and time consuming procedure. It has been determined that protein anabolic hormones and other anabolic enzymes provide optimal growth and weight gain results in early and throughout the growth cycle of the animal. It requires an immediate release/sustained release dual formulation that is still not possible to date.

Suitable descriptive steps for making such biodegradable polymers and implants with non-biodegradable polymers are described below in this case.

控制釋放配方中合成代謝劑之釋放速率可藉許多方法控 制。關於聚(D,L-乳交酯—共—乙交酯)扶聚物,載體基質之 降解速率可藉由減小聚合物鏈之大小及必然地分子量而增 加。增加活性合成代謝劑之量,其必然地降低活性共聚物 重量比例,可增加釋放速率。額外塑性劑與其他賦形劑之 加入甚至可加速降解與釋放。此種修改對熟悉此技藝者為 顯而易知的。 含生物可降解聚合物(例如,如聚(D,L-乳交酯-共—乙交 酯)共聚物)之移植物之製備可利用此技藝已知之任何方法The release rate of the anabolic agent in the controlled release formulation can be controlled in a number of ways. With regard to the poly(D,L-lactide-co-glycolide) eupolymer, the degradation rate of the carrier matrix can be increased by reducing the size of the polymer chain and the molecular weight inevitably. Increasing the amount of active anabolic agent, which inevitably reduces the weight ratio of the active copolymer, increases the rate of release. The addition of additional plasticizers and other excipients can even accelerate degradation and release. Such modifications are readily apparent to those skilled in the art. The preparation of a graft comprising a biodegradable polymer (e.g., a poly(D,L-lactide-co-glycolide) copolymer) can utilize any method known in the art.

I is completed. A descriptive step is as follows. Preferably, the anabolic active compound I is first dissolved in a suitable solvent which also dissolves, emulsifies or disperses the poly(D,L-lactide-co-glycolide) copolymer. Suitable dissolutions include organic solvents such as acetone, oxime, dioxins, other aromatic hydrocarbons, cyclic ethers, esters, alcohols, and the like, and mixtures thereof. The polymeric matrix material is also dissolved or dispersed in the solvent, and the resulting emulsion or solution can be mixed into a continuous phase. Surfactants can be added to the solution to prevent cohesion. The solvent is then removed, which is usually applied by heat, low pressure applications or both. The temperature used is not critical, but should not be too high to produce degradation of the active compound or the transplanted biodegradable matrix material. Once the solvent is removed, the solid dose graft can then be prepared using a standard ingot molding machine known in the art. Preferably, the anabolic agent used in the formulation of the present invention is a protein assimilating i. A commercially available formula for protein anabolic hormones is Ralgro® (from |

The amount of each type is determined based on the amount of protein assimilating the protein that is desired to be injected into the animal. For comparison purposes, dual-injection injections can be compared and controlled! Formulation tablets alone or protein anabolic hormone tablets are injected separately, so that the total amount of protein 1 anabolic hormone remains to be combined with the total protein assimilation factor of the dual formulation of the present invention. Growth-enhancing graft pills are usually injected subcutaneously into the ear or other livestock. After application, the water diffuses from the tissue of the animal into the drug bond and is driven by the hydration of the lactose i and the low degree of hydration by the anabolic agent. The dissolved activity is then diffused from the matrix structure into the systemic circulation of the animal. As evidenced by the examples, Applicants have found that the dual-prepared tablet of the present invention surprisingly produces a higher growth and weight gain in the test animals than in the controlled release tablet alone or in the protein anabolic hormone tablet alone. Another specific embodiment of the present invention reveals an anabolic metabolic composition and formulation for increasing the rate of growth of bovine stimuli, greater growth, and greater foraging efficiency.
