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).

Sterility USP <71>

A sterility test detects microbial contamination. A satisfactory result indicates that no contaminating microorganism has been found in the sample examined under the conditions of the test.

Rapid Sterility

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

Endotoxin USP <85>

An endotoxin test detects toxins that are released from the cell wall of disrupted gram-negative bacteria.

Microbial Identification

This test identifies microorganisms isolated during environmental monitoring 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>

An antimicrobial effectiveness test demonstrates the effectiveness of antimicrobial preservatives in preventing microbial proliferation in injections, topicals, oral products, single dose vials, and antacids packaged in multiple-dose containers.

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.

Available drugs:

  • Estriol

  • Estradiol

  • Estrone

  • Testosterone

  • Progesterone

  • Testosterone Propionate

  • Testosterone enanthate

  • Testosterone Cypionate

  • Methotrexate
