What is compounding and why do you need it?
Compounding is a process in which a pharmacist mixes certain drugs to either create a customized medication or a different drug delivery method suited to a patient's unique needs.
These are some examples of why compounding may be done:
- A medication is no longer being manufactured.
- A medication needs to be made without certain inactive ingredients such as preservatives, dyes, or binders for a patient who is allergic to these components.
- A specific dosage strength is unavailable commercially for the patient (for example, for a child or infant).
- Certain medications need to be combined, by the order of the physician.
- The medication formulation needs to be changed for a patient's needs, for example, from oral to topical (a cream, ointment, or patch) if a patient has trouble swallowing medication in pill or capsule form.
- The taste of the medication needs to be improved; this is an option for certain antibiotics often prescribed for young children.
- The purpose is for veterinary use. This is extremely important in the veterinary community because this group of patients may require a wide variety of flavors, dosage forms, and potency levels that often are commercially unavailable. Many drugs used for humans are also prescribed for animals.
