Warning Letter of the Week: non-uniformity edition

A love note for the CEO of Mylan Pharmaceuticals from the Center for Drug Evaluation and Research:
2. Your firm failed to thoroughly investigate any unexplained discrepancy or failure of a batch or any of its components to meet any of its specifications, whether or not the batch has already been distributed (21 CFR 211.192). 
Your investigations into out-of-specification (OOS) results and process deviations were inadequate. Root causes did not consistently include scientifically supported conclusions.... 
B. Your firm opened two manufacturing investigation reports, No. 1071629 on December 12, 2016, and No. 1106258 on January 25, 2017, to investigate atypically high assay and high variability content uniformity results for three batches of prednisolone sodium phosphate 10 mg orally disintegrating tablets (ODT). The investigations identified a root cause of untrained or inexperienced operators [redacted]. The investigation did not fully evaluate the processing factors that contribute to variability in your finished tablets. In particular, it did not evaluate the inherent variability of the [redacted] method used for charging [redacted], and identify more robust methods for performing this critical transfer that could prevent blend segregation and tablet dose non-uniformity. It also did not ensure improvements were adequately specified in batch records to enable an ongoing state of control. We acknowledge your firm’s market recall on April 30, 2018, of all batches of prednisolone sodium phosphate ODT within expiry from the U.S. market. 
C. Your firm opened multiple manufacturing investigation reports and trending assessments from July 2016 to October 2017 related to out-of-trend and OOS content uniformity results for metolazone 2.5 mg tablets. A scientifically justified root cause had not been identified, and effective CAPA plans had not been implemented. Despite substantial non-uniformity observed in multiple batches of metolazone 2.5 mg tablets, you continued to manufacture and release this drug product up to the time of the inspection.
I don't know anything about tableting, but I bet that non-uniformity isn't a fun problem to solve.

‘My friend, sorry, you must wait.’

An amusing aside in a New York Times article about luxury brands and their supply chains: 
Parterre, the British fragrance house, created its own on-site botanical garden at Keyneston Mill in Dorset, England, to grow the aromatic plants that would form the cornerstone of its limited-edition fragrances. Much the same instinct underpins the rise of cottage gardens at high-end hotels like Borgo Santo Pietro in Tuscany, Italy. Its Michelin-starred restaurant relies primarily on the organic farm attached to the property, which includes a dairy and an apiary. 
“They are securing the sources of their competitive advantage,” said Mario Ortelli, a luxury analyst with Ortelli & Company of London. “If your supplier works with 10 other luxury brands, and you’re not the most important client? When you ask for extra quantities, he can tell you, ‘My friend, sorry, you must wait.’”
It'd be interesting to know if Parterre purchased its own extraction as well?

Coke dissolves road dust?

Via the New York Times, this odd little article about using food as cleaning agents, including the classic 101 uses for Coca-Cola: 
...Speaking of sticky things, our reader Peggy offers this suggestion: “I use a product called Goo Gone but its main ingredient is orange oil. If you have no Goo Gone, rub a piece of orange on the gunk from stick-on labels and Bob’s your uncle.” 
Ketchup — yes, it’s a vegetable, just go with us — can be used to polish brass and copper. But if you’re out, and you happen to have a pineapple handy, you’re in luck. 
“Whenever I trim a pineapple, I grab a saltshaker and whichever of my copper bottom pots needs tarnish removed: Sprinkle salt, rub with pineapple peel — Voilà!” wrote another reader.... 
...We noted that Coca-Cola can be used to clear a slow-moving drain, clean a toilet bowl and remove motor oil and grease from clothing and pavement. You all had many uses to add. Bill writes: “If road oil and dust have made your windshield smeary, pour Coke on it. The windshield comes clean,” and Thomas added, “Coke rejuvenates old windshield wiper blades.”
Orange oil as a handy solvent makes sense to me, but ketchup to remove metal oxides? Also carbonated sugar water for motor oil?
