Preservative Efficacy Testing (PET)
Preservative efficacy testing (PET) is a crucial part of ensuring the safety and effectiveness of pharmaceutical formulations such as eye drops, nasal sprays, creams, and lotions. These products are susceptible to microbial contamination, which can compromise their safety and effectiveness.
What is Preservative Efficacy Testing?
Preservative efficacy testing involves subjecting pharmaceutical products to rigorous testing procedures to evaluate the effectiveness of their preservative systems. This testing assesses the ability of preservatives to inhibit or reduce the growth of microorganisms that may be introduced into the product during manufacturing or use.
Testing Procedure
-
Inoculation
Samples of the pharmaceuticals are inoculated with standardized cultures of relevant microorganisms.
-
Incubation
These samples are then incubated under conditions that promote microbial growth.
-
Evaluation
At specified intervals, samples are evaluated to enumerate the viable microbial population.
The effectiveness of the preservative system is determined by comparing the microbial growth in test samples with growth in control samples that lack preservatives. Significant inhibition or reduction in microbial growth in the test samples indicates the efficacy of the preservative system.
