According to an FDA spokesperson, an inspection revealed the firm "fails to test finished product for potency, failed to investigate complaints for ineffective products, failed to investigate violations of their own environmental sampling plan and fails to adequately maintain equipment and facilities used to manufacture sterile drug products".
21 C.F.R. 211.110 (a)(6) states that bioburden in-process testing must be conducted pursuant to written procedures during the manufacturing process of drug products. [3] The United States Pharmacopeia (USP) outlines several tests that can be done to quantitatively determine the bioburden of non-sterile drug products. [4]
Aseptic sampling is the process of aseptically withdrawing materials used in biopharmaceutical processes for analysis so as not contaminate or alter the sample or the source of the sample. [1] Aseptic samples are drawn throughout the entire biopharmaceutical process ( cell culture /fermentation, buffer & media prep, purification , final fill ...
Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.
A sampling plan to outline sampling methods both during and between production batches; Analysis methodology that allows for data scientific and risk oriented decision making based on statistical data. Variability limits should be defined and contingencies in the event of non-conforming data established
BFS-packaged eye drops for single use. Blow-Fill-Seal, also spelled as Blow/Fill/Seal, in this article abbreviated as BFS, is an automated manufacturing process by which plastic containers, such as bottles or ampoules are, in a continuous operation, blow-formed, filled, and sealed.
MIL-STD-105 D Quick reference Table, TABLE I and TABLE IIA. MIL-STD-105 was a United States defense standard that provided procedures and tables for sampling by attributes based on Walter A. Shewhart, Harry Romig, and Harold F. Dodge sampling inspection theories and mathematical formulas.
The laboratory procedure involves making serial dilutions of the sample (1:10, 1:100, 1:1000, etc.) in sterile water and cultivating these on nutrient agar in a dish that is sealed and incubated. Typical media include plate count agar for a general count or MacConkey agar to count Gram-negative bacteria such as E. coli .
