There are three typical situations that would result in a veterinarian needing to turn to a compounded medication for their patients.
When the best therapy for a patient is not commercially available
Drugs can become unavailable for any number of reasons. The most common factors are manufacturer backorders, recalls and discontinuations (for reasons other than safety). Frequently, and at an increasingly regular pace, a pharmaceutical manufacturer may temporarily halt production. Manufacturers can experience interruptions in the supply of active pharmaceutical ingredients (API) and other components of the commercial medicines they make. When situations like these occur, veterinarians often turn to compounding pharmacies to assure continuation of critical therapies.
When a manufactured drug is not available in the necessary strength, dosage form or flavor
In a typical companion-animal practice, veterinarians treat all sizes and shapes of pets from many species. In a single day, a practice may see a chubby cat, a chatty cockatiel, a charming Chihuahua and a cantankerous Collie. The animals seen in daily veterinary practice vary greatly in weight and food preferences, creating unique challenges for dosing and compliance. For some disease states, getting the dose exactly right can make the difference between helping and hurting a patient. Because of these factors, veterinarians frequently need to depart from commercially available options to get the right strength, dosage form or flavor. In many cases, compounded preparations are prescribed instead of manufactured drugs because an animal, literally, won’t swallow it. A specialized compounding pharmacy can be a critical ally in patient care.
When a patient is sensitive or allergic to a non-active component of a manufactured product
Some animals are allergic to components of manufactured medicines such as lactose, dyes, flavors, sweeteners and preservatives. Through custom compounding, veterinarians can finely tune not only the strength of the active pharmaceutical ingredients but also the other components of a medicine (for example, an ophthalmic can be changed from a corn oil base to an aqueous base to reduce irritation in the eye). Custom compounding can be a life-saving option when a pet can't tolerate a drug component.
