Compounding liquids for veterinary use often focusses on concentrating the medication and ensuring that the dose is measurable. A good vehicle is cod liver oil, since the fishy odour may appeal to many cats. As noted above, pastes are often used in dosing large animals. These may be prepared using an anhydrous polyethylene base, flavoured to improve palatability.
Troches are prepared as they are for humans.
Biscuits may be prepared by incorporating the drug into a dough of wheat germ, powedered milk, and a flavouring agent, rolled and cut to obtain appropriate doses, and baked or dried. Percutaneous patches may be prepared by placing the drug in a pluronic lecithin organogel, applied to the skin. The animal does not like to have dirty paws and will consequently lick the paste off, thereby providing an oral dosage route. Sweeting agents will often be employed to mask the bitter flavour of the drug. In this instance, when lick is NOT desired, a bitter agent will be added to the formulation to discourage licking.
