Amoxicillin Injection - Shijiazhuang Shimu Pharmaceutical Co., Ltd.|Veterinary Antibiotic, Broad-Spectrum Treatment

Amoxicillin Injection is a critical pharmaceutical product designed for the treatment of bacterial infections in veterinary medicine. Manufactured by Shijiazhuang Shimu Pharmaceutical Co., Ltd., this antibiotic belongs to the amino-penicillin family and is widely used in the treatment of respiratory diseases in cattle and pigs. This article delves into the pharmacokinetic properties, applications, advantages, technical specifications, and company background of Amoxicillin Injection, providing a detailed understanding of its role in modern veterinary care.

Pharmacokinetic Properties

Amoxicillin is a broad-spectrum antibiotic of the amino-penicillin family with close structural relationships to ampicillin. It acts as a bactericide, inhibiting the synthesis and repair of the bacterial mucopeptide cell wall. This mechanism makes it effective against both Gram-positive and Gram-negative bacteria. However, it is susceptible to bacterial beta-lactamases, which can reduce its efficacy in certain cases.

Pharmacokinetic studies reveal that in cattle, the maximum plasma concentration (Cmax) of 3.45 µg/ml is achieved 2.45 hours after intramuscular administration. In pigs, the Cmax of 3.54 µg/ml is reached within 2 hours. Amoxicillin is primarily distributed in the extracellular compartment, with a low degree of plasma protein binding (17%). This allows it to diffuse into tissues such as the lungs, pleura, and bronchial tissues, where it reaches concentrations similar to plasma levels. It also distributes into pleural, synovial, and lymphatic tissues.

The drug is metabolized in the liver through the hydrolysis of the β-lactam ring, forming inactive penicilloic acid (20%). Excretion occurs mainly via the kidneys, with a smaller portion eliminated through the biliary route and milk. This distribution and elimination profile ensures sustained therapeutic levels in the target tissues.

Indications and Applications

Amoxicillin Injection is indicated for the treatment of infections caused by both Gram-positive and Gram-negative bacteria. It is particularly effective against microorganisms involved in respiratory diseases in cattle, such as Mannheimia haemolytica and Pasteurella multocida. In pigs, it is also active against Pasteurella multocida, making it a valuable tool in veterinary medicine for managing respiratory infections.

The product is available in a concentration of 150 mg/ml, with a packaging of 100 ml/bottle. Its formulation ensures ease of administration and stability, making it suitable for use in various clinical settings.

Advantages of Amoxicillin Injection

One of the primary advantages of Amoxicillin Injection is its broad-spectrum activity, which allows it to target a wide range of bacterial pathogens. Its time-dependent mechanism of action ensures that it remains effective over extended periods, reducing the need for frequent dosing. Additionally, its low plasma protein binding facilitates rapid distribution to affected tissues, enhancing its therapeutic efficacy.

The product is also known for its safety profile when used as directed. While hypersensitivity reactions are possible, they are relatively rare. The withdrawal period for cattle and pigs is 28 days, and milk must be discarded for 4 hours post-treatment. These guidelines ensure the safety of both the animals and the food supply.

Important Considerations and Warnings

As with all penicillins, Amoxicillin Injection may cause hypersensitivity reactions in animals with known allergies to beta-lactams. It is crucial to avoid its use in such cases. Local reactions at the injection site, though rare, may occur and are typically transient.

Users are advised to shake the product well before administration to ensure uniform distribution of the active ingredient. Additionally, milk from treated animals should not be used for human consumption during the treatment period. For cattle, milk can be safely used 96 hours after the last dose.

Ensuring Compliance and Safety

Compliance with withdrawal periods is essential to prevent residues in animal products. The 28-day withdrawal period for cattle and pigs ensures that the drug is fully metabolized and excreted before the animals are processed for meat or milk. Adhering to these guidelines not only protects animal health but also safeguards the integrity of the food supply chain.

The product's storage requirements—sealing, protection from light, and keeping it out of children's reach—highlight the importance of proper handling and storage to maintain its efficacy and prevent accidental exposure.

Conclusion

Amoxicillin Injection is a vital tool in the management of bacterial infections in veterinary medicine. Its broad-spectrum activity, favorable pharmacokinetic profile, and safety considerations make it a preferred choice for treating respiratory diseases in cattle and pigs. Manufactured by Shijiazhuang Shimu Pharmaceutical Co., Ltd., the product exemplifies the company's commitment to quality and innovation in veterinary pharmaceuticals.
