Neomycin Sulfate for Prescription Compounding; Withdrawal of Approval of One Abbreviated New Drug Application

Краткое содержание

The Food and Drug Administration (FDA or Agency) is withdrawing approval of abbreviated new drug application (ANDA) 061579 for nonsterile neomycin sulfate powder for prescription compounding. The basis for the withdrawal is that the product is no longer considered safe as labeled due to clinical evidence that systemic exposure to neomycin sulfate can induce significant toxicity, including ototoxicity (manifested as sensorineural hearing loss), nephrotoxicity, and neuromuscular blockade. The holder of this ANDA has waived its opportunity for a hearing.
