Potency and stability of compounded cyclophosphamide: a pilot study.
1Department of Medical Sciences, School of Veterinary Medicine, University of Wisconsin-Madison, Madison, WI, USA.
Compounded veterinary oncology drugs, specifically cyclophosphamide capsules, showed concerning potency issues in a pilot study. Stability was generally good, but further research and collaboration are needed for safe drug delivery.
Area of Science:
- Veterinary Pharmacology
- Compounded Medications
- Oncology Drug Analysis
Background:
- Compounding of drugs for veterinary oncology is a growing practice.
- Ensuring the quality and accuracy of compounded medications is crucial for patient safety.
Purpose of the Study:
- To evaluate the potency and stability of compounded cyclophosphamide capsules for veterinary use.
- To identify potential quality control issues in veterinary drug compounding.
Main Methods:
- Obtained 15 mg cyclophosphamide capsules from five compounding pharmacies.
- Performed potency analyses at two time points.
- Assessed drug stability over 60 days.
Main Results:
- Potency results were inadequate for 4 out of 10 analyzed samples (four out of five pharmacies).
- Stability at 60 days was acceptable for all but one sample.
- The study highlights significant concerns regarding the quality of compounded chemotherapy drugs.
Conclusions:
- Pilot study indicates potential issues with potency in compounded veterinary oncology drugs.
- Further studies are required to validate these findings.
- Collaboration among pharmacists, veterinarians, and regulatory bodies is essential for ensuring safe and accurate compounded drug delivery in animals.

Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
