A Texas man pleaded guilty Tuesday to one count of adulterating a drug that was used in cataract surgeries. According to court documents, Jack Randall Munn, 71, of Dallas, a licensed pharmacist and former owner of Guardian Pharmacy Services (Guardian), a Dallas pharmacy, oversaw the compounding of the drug for two outpatient Dallas surgical centers in 2016 and 2017. The drug, a combination of an antibiotic and a steroid, contained an excessive amount of an inactive ingredient that can damage sensitive eye tissue. At the time of the events described in court documents, Munn represented to the surgical centers that Guardian could compound the drug in a manner safe for injection into patients’ eyes. However, the drug made by Guardian contained an excessive amount of the inactive ingredient, causing its purity and quality to fall below that which it was represented to possess.
