Amoxicillin Injection for Cattle & Pigs | Shijiazhuang Shimu Pharmaceutical Co., Ltd.

Amoxicillin Injection is a critical veterinary medication designed to combat bacterial infections in livestock, particularly in cattle and pigs. Developed by Shijiazhuang Shimu Pharmaceutical Co., Ltd., this broad-spectrum antibiotic is widely used in veterinary medicine for its efficacy and safety profile. This article provides a comprehensive overview of its pharmacokinetic properties, technical specifications, application scenarios, and the company's commitment to quality.

Understanding Amoxicillin Injection

Amoxicillin is a semisynthetic penicillin derivative that belongs to the amino-penicillin family. It is structurally similar to ampicillin but offers enhanced activity against a broader range of bacteria. As a bactericidal agent, amoxicillin works by inhibiting the synthesis and repair of bacterial cell walls, making it highly effective against both Gram-positive and Gram-negative microorganisms. This mechanism of action is crucial for treating infections caused by pathogens such as Mannheimia haemolytica and Pasteurella multocida, which are commonly associated with respiratory diseases in cattle and pigs.

One of the key advantages of Amoxicillin Injection is its time-dependent efficacy. Unlike concentration-dependent antibiotics, amoxicillin requires sustained exposure to bacterial targets to achieve optimal therapeutic outcomes. This characteristic necessitates careful dosing and administration protocols to ensure prolonged drug levels in the bloodstream.

Pharmacokinetic Properties

The pharmacokinetics of amoxicillin in livestock are well-documented, providing insights into its absorption, distribution, metabolism, and excretion. After intramuscular administration, the drug reaches peak plasma concentrations (Cmax) within 2–2.45 hours in cattle and 2 hours in pigs. The bioavailability of amoxicillin is approximately 80–90%, ensuring rapid systemic availability.

Amoxicillin exhibits low plasma protein binding (17%), allowing it to distribute effectively into extracellular compartments. It achieves therapeutic concentrations in critical tissues such as the lungs, pleura, and bronchial tissues, which are often affected by respiratory infections. The drug also diffuses into pleural and synovial fluids, making it suitable for treating infections in these areas.

Metabolism of amoxicillin primarily occurs in the liver, where the β-lactam ring is hydrolyzed to form inactive penicilloic acid (20% of the dose). The majority of the drug is excreted unchanged via the kidneys, with a smaller fraction eliminated through the biliary route and milk. This excretion pattern is important for determining withdrawal periods and ensuring compliance with food safety regulations.

Application Scenarios

Amoxicillin Injection is widely used in veterinary medicine for the treatment of respiratory infections in cattle and pigs. Its efficacy against Mannheimia haemolytica and Pasteurella multocida makes it a preferred choice for managing bovine respiratory disease (BRD) and porcine respiratory disease (PRD). These infections are major economic concerns for livestock producers, as they can lead to significant morbidity, mortality, and reduced productivity.

In addition to respiratory infections, Amoxicillin Injection is effective against a range of systemic bacterial infections, including skin and soft tissue infections, urinary tract infections, and septicemia. Its broad-spectrum activity ensures that it can address multiple pathogens simultaneously, reducing the need for combination therapies.

The short withdrawal period (4 hours for milk) and long shelf life (3 years) make this product ideal for large-scale livestock operations. Farmers and veterinarians can rely on its stability and safety, ensuring compliance with food safety standards while maintaining animal health.

Important Safety Information

As with all beta-lactam antibiotics, Amoxicillin Injection carries a risk of hypersensitivity reactions. It should not be administered to animals with a known allergy to penicillins or cephalosporins. Local reactions at the injection site, such as swelling or redness, are rare but may occur. These reactions are typically transient and resolve without intervention.

Milk for human consumption must be discarded during treatment and for 4 hours post-administration. For cattle and pigs, the withdrawal period of 28 days ensures that residual drug levels in meat are below detectable limits, safeguarding consumer health.

Proper storage is essential to maintain the integrity of the product. The medication should be kept in a sealed container111, protected from light, and stored in a cool, dry place. It is also critical to keep the product out of reach of children to prevent accidental ingestion.
