Supports compounding standards.

The research article titled, “Effects of compounding and storage conditions on stability of pergolide mesylate” investigates the importance of adhering to the official US Pharmacopeia (USP) when formulating pergolide mesylate for horses. The paper warns about potential issues arising from extended shelf life imposed by some vets, against the recommended 30-day expiration date.

Elucidating the Research

• The research paper validates the necessity of adhering to the official US Pharmacopeia (USP) monograph for compounding pergolide, a medicine prescribed to horses. This particular monograph serves as a standard guideline for the compounding industry, ensuring the production of safe and effective medication.
• According to the guideline, compounding pharmacies are required to impose a 30-day expiration date on compounded pergolide prescriptions. This reflects the shelf-life of the medication and how its stability can be influenced by storage conditions.
• The author warns about the prevalent but inappropriate practice in the compounding industry where veterinarians receive pergolide with extended expiry dates, ranging from 30 to 180 days. This discrepancy can lead to potential risks and liabilities due to diminished drug effectiveness.

Concerns Raised

• The author emphasizes the responsibility of the veterinary profession to adhere to evidence-based practices and uphold ethical standards. This includes following the USP standard for pergolide compounding without exception.
• Deviating from these standards, like extending the shelf life of a drug for client convenience, is admonished as it jeopardizes the health of the animals and compromises the reputation of the profession.
• The author highlights that educated clients will favor what’s best for their pets and any issues arising from poor drug practices can have far-reaching negative impacts.

Takeaway

• The paper puts forth a strong argument for the veterinary profession to be proactive in adhering to prescribed compounding standards to maintain trust and to prevent any potential negative consequences.
• It appreciates the role of veterinary pharmacologists in providing these necessary guidelines and encourages the profession to give them due credit.
