Methacycline is a tetracycline antibiotic. Similar to other tetracyclines, it has a wide spectrum of antimicrobial action. It is active against most Gram-positive bacteria (pneumococci, streptococci, staphylococci) and Gram-negative bacteria (E. coli, salmonella, shigella, etc.), and towards agents causing onithosis, psittacosis, trachoma, and some Protozoa. Like other tetracyclines, the general usefulness of methacycline has been reduced with the onset of bacterial resistance. Methacycline inhibits the binding of aminoacyl-tRNA to the mRNA-ribosome complex. Methacycline inhibits cell growth by inhibiting translation. It binds to the 16S part of the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. Methacycline is mostly used for the treatment of acute bacterial exacerbations of chronic bronchitis.

Flunixin meglumine is a potent, non-narcotic, non-steroidal, analgesic agent with anti-inflammatory and anti-pyretic activity was approved to use in horses, cattle and pigs. In horses it is recommended for the alleviation of inflammation and pain associated with musculoskeletal disorders. It is also recommended for the alleviation of visceral pain associated with colic. In the cattle: it is indicated for the control of pyrexia associated with bovine respiratory disease, endotoxemia and acute bovine mastitis. It is also indicated for the control of inflammation in endotoxemia. Flunixin persists in inflammatory tissues and is associated with anti-inflammatory properties which extend well beyond the period associated with detectable plasma drug concentration. Flunixin meglumine is classified as a carboxylic acid. Its mechanism of action is believed to be primarily via the inhibition of cyclooxygenase (COX) enzymes. This inhibition results in decreased formation of cyclooxygenase-derived eicosanoids involved in the pathophysiology of inflammation, such as thromboxanes and prostaglandins.
