Oral suspensions, or drenches, are a popular and common approach to overcoming the many obstacles of administering medicines to animals. Formulating solid dosage forms into suspensions enables line extensions of existing products for various animal species. Suspensions can be administered orally by drench guns or syringes, and can be mixed into feed or metered by dosing pumps into drinking water. The selection of a suitable stabilizer to adjust the required rheological properties is a major challenge in the development of suspensions. The goal of this study was to develop an oral suspension for animals with optimal stability, administration, and palatability.
