What happened

Amerisource Health Services LLC has initiated a Class III recall for Primidone Tablets USP (50 mg) due to trace amounts of Acemetacin API cross-contamination within the drug's active pharmaceutical ingredient.

Who it affects

This recall affects Amerisource Health Services LLC, American Health Packaging, and healthcare facilities or pharmacies utilizing unit-dose blister packs of 50 mg Primidone tablets.

Why it matters

A Class III recall indicates that use of or exposure to the product is not likely to cause adverse health consequences. However, the presence of trace API contamination suggests a potential failure in cleaning validation or supplier quality management at the API manufacturing level, which may require an investigation into the robustness of the manufacturer's contamination control strategy.

Practical takeaway

QA teams should verify if any batches of Primidone (NDC 68084-202-01) remain in inventory; Regulatory and Supply Chain departments should monitor for potential supply disruptions if this API contamination affects multiple lots or alternative repackagers.
