Tiamulin is a diterpene antimicrobial with a pleuromutilin chemical structure similar to that of valnemulin. The activity of tiamulin is largely confined to gram-positive micro-organisms and mycoplasma. Tiamulin acts by inhibiting protein synthesis at the ribosomal level. In veterinary medicine, tiamulin is used for treatment and prophylaxis of dysentery, pneumonia and mycoplasmal infections in pigs and poultry. Tiamulin is available as a 2, 10 or 20% premix for pigs and poultry, a 12.5% solution or 45% water soluble powder for addition to drinking water for pigs and poultry, or a 10% injectable formulation for pigs. Tiamulin inhibits protein synthesis by targeting the 50S bacterial ribosomal subunit and binding to peptidyl transferase, the enzyme responsible for forming peptide bonds between amino acids.

Domperidone is a peripherally selective D2 receptor antagonist. It acts as an antiemetic and a prokinetic agent through its effects on the chemoreceptor trigger zone and motor function of the stomach and small intestine. Domperidone was not approved in USA due to risks of cardiac arrhythmias, cardiac arrest, and sudden death, but is available in other countries. However, FDA allows access to Domperidone through an expanded access investigational new drug application (IND) to patients with gastroesophageal reflux disease with upper GI symptoms, gastroparesis, and chronic constipation. As an “off-label” use, domperidone is prescribed to breastfeeding women to enhance their milk production.

Metomidate is a non-barbiturate imidazole which produces a sleepy condition of 20-60 minutes duration without substantial analgesia. Since the beginning of 1997 the use of the hypnotic drug metomidate (Hypnodil) in swine is nor longer allowed. This ban caused a substantial therapeutic deficit for anesthesia in swine. 11C-metomidate may be used with positron emission tomography which can differentiate adrenocortical from nonadrenocortical tumors and a suspected adrenocortical cancer may be characterized and staged before surgery. Metomidate hydrochloride is for the sedation and anesthesia of aquarium and non-food fish species. Aquacalm has been granted Indexed status by the FDA for this purpose.

Medronic acid (conjugate base, medronate) is a diagnostic agent that is used in complex with technetium Tc-99m for imaging delineate areas of altered osteogenesis. Upon administration the complex binds to hydroxyapatite crystals in bone.

Danofloxacin is a quinolone antibacterial agent for veterinary medicine. The drug is approved by FDA for the treatment of bovine infectious respiratory disease under the name Advocin (mesylate salt). Danofloxacin exerts its action by inhibiting bacterial DNA gyrase.

Thioctic acid also known as alpha-lipoic acid is a dietary supplement, which is a common ingredient in OTC (over-the-counter) multivitamin formulas and anti-aging supplements. Thioctic acid exists in both R- and S-enantiomeric forms, however, only R-form is essential as a cofactor in biological systems (the acid is coupled via an amide linkage to a lysine of several multienzyme complexes, such as the pyruvate dehydrogenase complex, the alpha-ketoglutarate dehydrogenase complex, the glycine cleavage system and the branched-chain oxo acid dehydrogenase complex). Most commercially available thioctic acid supplements are a mixture of both R and S enantiomers or R-form alone. Several studies have shown that the acid has beneficial effect on diabetes complications, cancer, glaucome, liver disease, etc. The mechanisms of thioctic acid is related to its antioxidant properties, metal chelator properties, however, those mechanisms need futher confirmation.
