Stability Studies (Beyond Use Dating)

A stability study measures the extent to which a product retains, within specified limits, and throughout its period of storage and use, the same properties and characteristics that it possessed at the time of compounding.

A study commonly includes: a stability indicating method assay, sterility (for sterile preparations), endotoxin (for most sterile preparations), pH, visual inspection, particulate matter, preservative effectiveness, preservative quantification, microbial limits (for non-sterile preparations), and the absence of specified organisms (for non-sterile preparations).



Container Closure Testing

The container closure system for a drug product provides critical protection for stability and sterility. ARL offers USP <1207> container closure integrity testing (CCIT) on IV bags, syringes, cassettes, and vials. Three types of leaks that can be detected during CCIT include: 

  1. Entry of microorganisms
  2. Escape of the product dosage form or entry of liquids or solids
  3. Escape of nitrogen gas or entry of oxygen, water vapor, or air gase



Rapid Sterility

A rapid sterility test detects microbial contamination. This validated alternative sterility test method per USP <1223> is effective and reliable for 503A and 503B Facilities. Rapid test provides objective results in as little as six days.



Microbial Identification

This test identifies microorganisms isolated during different phases of manufacturing and quality testing to the genus/species level using DNA sequencing.


Environmental Monitoring Plate Testing - Personnel and Surfaces

ARL will incubate client growth media samples at a specified time and temperature.  Once complete, the media will be examined for microbial growth and a CFU count provided to the client on a CoA.

Antimicrobial Effectiveness Testing USP <51>

Particulate Matter USP <788>/<789>

A particulate matter tests for the presence of extraneous substances including: dust, glass, drug precipitates, rubber and other insoluble materials.


Microbial Disinfectant Cleaning Challenge Studies

Microbial cleaning studies are essential to validating a facility’s cleaning SOP.  Pharmacies must demonstrate that cleaning agents, combined with instructions and procedures for their use, remove microbial contamination from surface areas where sterile drug products are compounded.


USP <800> Surface Wipe Sampling Test

This test measures the level of hazardous drug surface residue to verify workplace safety.

Drug Diversion Testing

Drug Diversion is the transfer of licit drugs for illicit purposes. ARL Bio Pharma's investigative services can provide additional evidence of drug diversion. Testing services include: drug identity confirmation, unknown drug identification and drug concentration analysis.
