Preservative Efficacy Test

Antimicrobial EfficacyAntimicrobials are substances that inhibit or inactivate the growth of microorganisms. Pharmacopoeial standards require multi-dose pharmaceutical products to contain antimicrobial preservatives in order to protect against microbial growth and will also require preservative efficacy testing to ensure the safety of the product throughout its life cycle. Similarly, regulations on medical devices may also require proof of antimicrobial barrier efficacy, particularly if the marketing of the device makes claims in regards to antimicrobial efficacy. At Wickham Laboratories, we offer a range of antimicrobial efficacy testing services.

Efficacy of Antimicrobial Preservatives in Pharmaceutical Products

Preservative efficacy testing is a routine method in our microbiology labs and we offer validation and analysis to assess the efficacy of preservation systems across a wide range of product types including parenteral, ophthalmic, topical or oral.

Our extensive in-house culture collection also enables us to offer efficacy studies following pharmacopoeial requirements, or customised to clients’ individual requirements.
