Zeleris is a veterinary tratment used to treat cattle with bovine respiratory illness (BRD, a condition affecting the lungs) associated with a high temperature, which is due to the bacteria Mannheimia haemolytica, Pasteurella multocida and Histophilus somni. Zeleris contains the active substances florfenicol and meloxicam.
Florfenicol is a broad-spectrum antibiotic which stops bacteria from growing by blocking the activity of ribosomes, the part of the bacterial cells where proteins are produced. Meloxicam belongs to a class of tratments called non-steroidal anti-inflammatory drugs (NSAIDs). Meloxicam acts by blocking an enzyme called cyclooxygenase which is involved in the production of prostaglandins. As prostaglandins are substances that trigger inflammation, pain, exudation (fluid that leaks out of blood vessels during an inflammation) and fever, meloxicam reduces these signs of illness.
