Stability Studies 

According to the United States Food and Drug Administration (FDA) and the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), the purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re-test period for the drug substance or a shelf life for the drug product and recommended storage conditions.

Sterile vs Non-Sterile

Stability studies for sterile products generally include:

  • Appearance (Color, clarity, order)
  • Antimicrobial effectiveness testing
  • Assy/Potency measurement using stability indication validated analytical method(s)
  • Container-closure integrity testing

USP <51> Antimicrobial Effectiveness Testing

A microbiologist looking at a contact plate under a magnifying glass.


Antimicrobial effectiveness, whether inherent in the product or as a result of an antimicrobial preservative, must be demonstrated through USP <51> antimicrobial effectiveness testing. Sterile articles packaged in multi-dose containers must be free of microorganisms throughout their entire shelf life. Due to the potential for the introduction of microorganisms through the repeated withdrawal of individual doses, sterile products that are packaged in multi-dose containers should contain an antimicrobial preservative. However, the concentration of an added antimicrobial preservative can be kept to a minimum if the ingredients of the compounded formulation possess an intrinsic antimicrobial activity.  Microbiological Department

USP <60> Burkholderia Cepacia Complex (Bcc)

Determining the presence of Bcc is vital, especially for inhalation use or aqueous preparations for oral, oromucosal, cutaneous, or nasal use. A USP <60> Burkholderia Cepacia Complex test determines whether a substance or preparation complies with an established specification for microbiological quality.

USP <71> Method Suitability Testing

USP <71> Method Suitability Testing (MST) must be performed prior to being able to claim that the results of a USP <71> sterility test provide evidence of a preparation’s sterility. 

USP <71> Sterility Tests

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.  Method suitability is performed to ensure contamination can be detected under the conditions of the test, providing confidence in the test result.

USP <71> outlines the compendial requirements for sterility testing that must be followed in order to be able to claim that the results of the test provide evidence that the product is sterile.  Testing Services

USP <85> Bacterial Endotoxins Testing 

​As bacterial endotoxins can pose health and safety hazards to patients, USP <85> requires bacterial endotoxin testing to detect and quantify the presence of endotoxins from Gram-negative bacteria in sterile compounds.

To ensure patient safety, the quantity of bacterial endotoxins may not exceed threshold limits defined in USP <85>. For each bacterial endotoxin test, inhibition validation testing is performed. This testing confirms that there are no components of the formulation that will interfere with the bacterial endotoxin test and that the testing used is sensitive enough to provide meaningful, accurate data.  Pricing Request

USP <788> & USP <789> — Particulate Matter

Solutions must be essentially free from observable particulate matter. Due to the small amount of material and the heterogenous composition that particulate matter represents, it cannot be quantitated by chemical analysis alone. Particulate Matter testing is performed on all parenteral solutions to determine the cleanliness and stability of the solution.

Injections and Ophthalmic Solutions

USP <788> Particle Matter In Injections

The USP (United States Pharmacopeial) General Chapter <788> states,  “Particulate matter in injections and parenteral infusions consists of extraneous mobile undissolved particles, other than gas bubbles, unintentionally present in the solutions.”  There are two procedures that may be used to determine the particulate matter:

Method 1: Light Obscuration Particle Count Test

This method is preferred when examining injections and parenteral infusions for subvisible particles. Method 1 is broken down into Test 1.A and Test 1.B. Please see the USP <788> reference for details.

Method 2: Microscopic Particle Count Test

When Method 1 is not applicable, e.g., in the case of preparations having reduced clarity or increased viscosity, the test should be carried out according to Method 2. Method 2 uses a suitable binocular microscope, a filter assembly for retaining particulate matter, and a membrane filter for examination.

USP <789> Particle Matter in Ophthalmic Solutions

USP <788> states, “Particulate matter consists of mobile, randomly sourced, extraneous substances, other than gas bubbles, that cannot be quantitated by chemical analysis because of the small amount of material they represent and because of their heterogeneous composition. Ophthalmic solutions should be essentially free from particles that can be observed on visual inspection. The tests described herein are physical tests performed for the purpose of enumerating extraneous particles within specific size ranges.”

USP <1207> Container-Closure Integrity Testing

USP <1207> container-closure integrity testing demonstrates the ability of the container-closure system to maintain the integrity of its microbial barrier throughout the entire shelf-life of a product.

Eagle utilizes a pressure decay to test container-closure integrity, which is one of the deterministic methods recommended by USP <1207>. As sterility is an event-related occurrence, container-closure integrity testing is performed to support the claim that the sterile containers in which the preparation is packaged are capable of maintaining the sterility of the product throughout its shelf life.
