Selected passages from the FDA letter
Quoted FDA text from the published dataset. These selected excerpts are not the complete letter.
Passage 1Your firm compounded drug products using ammonium tetrathiomolybdate. Drug products compounded using ammonium tetrathiomolybdate are not eligible for the exemptions provided by section 503A(a), because ammonium tetrathiomolybdate is not the subject of an applicable USP or NF monograph, is not a component of an FDA-approved human drug and does not appear on the 503A bulks list.
Passage 2Your firm compounded drug products using a bulk drug substance manufactured by **(b)(4)**, which is not a registered establishment under section 510 of the FDCA.
Passage 3The ineligible drug products you compounded are intended for conditions not amenable to self-diagnosis and treatment by individuals who are not medical practitioners; therefore, adequate directions for use cannot be written so that a layman can use these products safely for their intended uses. Consequently, their labeling fails to bear adequate directions for their intended uses.
Passage 4Tranilast was nominated for inclusion on the 503A bulks list, was evaluated by Pharmacy Compounding Advisory Committee and by FDA and FDA determined not to include tranilast on the list of bulk drug substances that can be used in compounding under section 503A, found at 21 C.F.R. 216.23(a). See 21 C.F.R. 216.23(b)(4). Accordingly, drug products compounded using tranilast are not eligible for the exemptions provided by section 503A(a).
